Enemy of God

PART ONE The Dark Road

Today I have been thinking about the dead. This is the last day of the old year. The bracken on the hill has turned brown, the elms at the valley’s end have lost their leaves and the winter slaughter of our cattle has begun. Tonight is Samain Eve.

Tonight the curtain that separates the dead from the living will quiver, fray, and finally vanish. Tonight the dead will cross the bridge of swords. Tonight the dead will come from the Otherworld to this world, but we shall not see them. They will be shadows in darkness, mere whispers of wind in a windless night, but they will be here.

Bishop Sansum, the saint who rules our small community of monks, scoffs at this belief. The dead, he says, do not have shadow-bodies, nor can they cross the sword bridge, but instead they lie in their cold graves and wait for the final coming of our Lord Jesus Christ. It is proper, he says, for us to remember the dead and to pray for their immortal souls, but their bodies are gone. They are corrupt. Their eyes have melted to leave dark holes in their skulls, worms liquefy their bellies, and mould furs their bones. The saint insists that the dead do not trouble the living on Samain Eve, yet even he will take care to leave a loaf of bread beside the monastery hearth this night. He will pretend it is carelessness, but all the same there will be a loaf of bread and a pitcher of water beside the kitchen ashes tonight. I shall leave more. A cup of mead and a piece of salmon. They are small gifts, but all I can afford, and tonight I shall place them in the shadows by the hearth then go to my monk’s cell and welcome the dead who will come to this cold house on its bare hill.

I shall name the dead. Ceinwyn, Guinevere, Nimue, Merlin, Lancelot, Galahad, Dian, Sagramor; the list could fill two parchments. So many dead. Their footsteps will not stir a rush on the floor nor frighten the mice that live in the monastery’s thatched roof, but even Bishop Sansum knows that our cats will arch their backs and hiss from the kitchen corners as the shadows that are not shadows come to our hearth to find the gifts that deter them from working mischief.

So today I have been thinking about the dead.

I am old now, maybe as old as Merlin was, though not nearly so wise. I think that Bishop Sansum and I are the only men living from the great days and I alone remember them fondly. Maybe some others still live. In Ireland, perhaps, or in the wastes north of Lothian, but I do not know of them, though this much I do know: that if any others do live, then they, like me, cower from the encroaching darkness like cats shrinking from this night’s shadows. All that we loved is broken, all that we made is pulled down and all that we sowed is reaped by the Saxons. We British cling to the high western lands and talk of revenge, but there is no sword that will fight a great darkness. There are times, too frequent now, when all I want is to be with the dead. Bishop Sansum applauds that wish and tells me it is only right that I should yearn to be in heaven at God’s right hand, but I do not think I shall reach the saints’ heaven. I have sinned too much and thus fear hell, but still hope, against my faith, that I will pass to the Otherworld instead. For there, under the apple trees of four-towered Annwn, waits a table heaped with food and crowded with the shadowbodies of all my old friends. Merlin will be cajoling, lecturing, grumbling and mocking. Galahad will be bursting to interrupt and Culhwch, bored with so much talk, will steal a larger portion of beef and think no one notices. And Ceinwyn will be there, dear lovely Ceinwyn, bringing peace to the turmoil roused by Nimue.

But I am still cursed by breath. I live while my friends feast, and as long as I live I shall write this tale of Arthur. I write at the behest of Queen Igraine, the young wife of King Brochvael of Powys who is the protector of our small monastery. Igraine wanted to know all I can remember of Arthur and so I began to write these tales down, but Bishop Sansum disapproves of the task. He says Arthur was the Enemy of God, a spawn of the devil, and so I am writing the tales in my native Saxon tongue that the saint does not speak. Igraine and I have told the saint that I am writing the gospel of our Lord Jesus Christ in the enemy’s language and maybe he believes us, or maybe he is biding his time until he can prove our falsehood and then punish me.

I write each day. Igraine comes frequently to the monastery to pray that God will grant her womb the blessing of a child, and when her prayers are done she takes the finished skins away and has them translated into British by the clerk of Brochvael’s justice. I think she changes the story then, making it match the Arthur she wants rather than the Arthur who was, but perhaps that does not matter for who will ever read this tale? I am like a man building a wall of mud and wattle to resist an imminent flood. The darkness comes when no man will read. There will just be Saxons.

So I write about the dead and the writing passes the time until I can join them; the time when Brother Derfel, a humble monk of Dinnewrac, will again be Lord Derfel Cadarn, Derfel the Mighty, Champion of Dumnonia and beloved friend of Arthur. But now I am just a cold old monk scribbling memories with my one remaining hand. And tonight is Samain Eve and tomorrow is a new year. The winter is coming. The dead leaves lie in shining drifts against the hedgerows, there are redwings in the stubble, gulls have flown inland from the sea and woodcock gather under the full moon. It is a good season, Igraine tells me, to write of old things and so she has brought me a fresh pile of skins, a flask of newly mixed ink and a sheaf of quills. Tell me of Arthur, she says, of golden Arthur, our last and best hope, our king who never was a king, the Enemy of God and the scourge of Saxons. Tell me of Arthur. A field after battle is a dreadful thing.

We had won, but there was no elation in our souls, just weariness and relief. We shivered about our fires and tried not to think of the ghouls and spirits that stalked the dark where the dead of Lugg Vale lay. Some of us slept, but none slept well for the nightmares of battle’s end harried us. I woke in the black hours, startled out of sleep by the memory of a spear thrust that had so nearly skewered my belly. Issa had saved me, pushing the enemy’s spear away with the edge of his shield, but I was haunted by what had so nearly happened. I tried to sleep again, but the memory of that spear thrust kept me awake, and so at last, shivering and weary, I stood and drew my cloak about me. The vale was lit by guttering fires, and in the dark between the flames there drifted a miasma of smoke and river mist. Some things moved in the smoke, but whether they were ghosts or the living I could not tell.

‘You can’t sleep, Derfel?’ A voice spoke softly from the doorway of the Roman building where the body of King Gorfyddyd lay.

I turned to see it was Arthur who watched me. ‘I can’t sleep. Lord,’ I admitted. He picked his way through the sleeping warriors. He wore one of the long white cloaks that he liked so much and, in the fiery night, the garment seemed to shine. There was no mud on it, or any blood, and I realized he must have kept the cloak bundled safe for something clean to wear after battle. The rest of us would not have cared if we had ended the fight stark naked so long as we lived, but Arthur was ever a fastidious man. He was bare-headed and his hair still showed the indentations where the helmet had clasped his skull. ‘I never sleep well after battle,’ he said, ‘not for a week at least. Then comes a blessed night of rest.’ He smiled at me. ‘I am in your debt.’

‘No, Lord,’ I said, though in truth he was in my debt. Sagramor and I had held Lugg Vale all that long day, fighting in the shield-wall against a vast horde of enemies, and Arthur had failed to rescue us. A rescue had come at last, and victory with it, but of all Arthur’s battles Lugg Vale was the nearest to a defeat. Until the last battle.

‘I, at least, will remember the debt,’ he said fondly, ‘even if you do not. It is time to make you wealthy, Derfel, you and your men.’ He smiled and took my elbow to lead me to a bare patch of earth where our voices would not disturb the restless sleep of the warriors who lay closer to the smoking fires. The ground was damp and rain had puddled in the deep scars left by the hoofs of Arthur’s big horses. I wondered if horses dreamed of battle, then wondered if the dead, newly arrived in the Otherworld, still shuddered at the memory of the sword stroke or spear blow that had sent their souls across the bridge of swords. ‘I suppose Gundleus is dead?’ Arthur interrupted my thoughts.

‘Dead, Lord,’ I confirmed. The King of Siluria had died earlier in the evening, but I had not seen Arthur since the moment when Nimue had pinched out her enemy’s life.

‘I heard him screaming,’ Arthur said in a matter-of-fact voice.

‘All Britain must have heard him screaming,’ I answered just as drily. Nimue had taken the King’s dark soul piece by piece, all the while crooning her revenge on the man who had raped her and taken one of her eyes.

‘So Siluria needs a King,’ Arthur said, then stared down the long vale to where the black shapes drifted in the mist and smoke. His clean-shaven face was shadowed by the flames, giving him a gaunt look. He was not a handsome man, but nor was he ugly. Rather he had a singular face; long, bony and strong. In repose it was a rueful face, suggesting sympathy and thoughtfulness, but in conversation it was animated by enthusiasm and a quick smile. He was still young then, just thirty years old, and his short-cropped hair was untouched by grey. ‘Come,’ he touched my arm and gestured down the vale.

‘You’d walk among the dead?’ I pulled back aghast. I would have waited till dawn had chased the ghouls away before venturing away from the protective firelight.

‘We made them into the dead, Derfel, you and I,’ Arthur said, ‘so they should fear us, should they not?’ He was never a superstitious man, not like the rest of us who craved blessings, treasured amulets and watched every moment for omens that might warn against dangers. Arthur moved through that spirit world like a blind man. ‘Come,’ he said, touching my arm again.

So we walked into the dark. They were not all dead, those things that lay in the mist, for some called piteously for help, but Arthur, normally the kindest of men, was deaf to the feeble cries. He was thinking about Britain. ‘I’m going south tomorrow,’ he said, ‘to see Tewdric’ King Tewdric of Gwent was our ally, but he had refused to send his men to Lugg Vale, believing that victory was impossible. The King was in our debt now, for we had won his war for him, but Arthur was not a man to hold a grudge. ‘I’ll ask Tewdric to send men east to face the Saxons,’ Arthur went on, ‘but I’ll send Sagramor as well. That should hold the frontier through the winter. Your men,’ he gave me a swift smile, ‘deserve a rest.’

The smile told me that there would be no rest. ‘They will do whatever you ask,’ I answered dutifully. I was walking stiffly, wary of the circling shadows and making the sign against evil with my right hand. Some souls, newly ripped from their bodies, do not find the entrance to the Otherworld, but instead wander the earth’s surface looking for their old bodies and seeking revenge on their killers. Many of those souls were in Lugg Vale that night and I feared them, but Arthur, oblivious of their threat, strolled carelessly through the field of death with one hand holding up the skirts of his cloak to keep it free of the wet grass and thick mud.

‘I want your men in Siluria,’ he said decisively. ‘Oengus Mac Airem will want to plunder it, but he must be restrained.’ Oengus was the Irish King of Demetia who had changed sides in the battle to give Arthur victory and the Irishman’s price was a share of slaves and wealth from the dead Gundleus’s kingdom. ‘He can take a hundred slaves,’ Arthur decreed, ‘and one third of Gundleus’s treasury. He’s agreed to that, but he’ll still try to cheat us.’

‘I’ll make sure he doesn’t, Lord.’

‘No, not you. Will you let Galahad lead your men?’

I nodded, hiding my surprise. ‘So what do you want of me?’ I asked.

‘Siluria is a problem,’ Arthur went on, ignoring my question. He stopped, frowning as he thought about Gundleus’s kingdom. ‘It’s been ill-ruled, Derfel, ill-ruled.’ He spoke with a deep distaste. To the rest of us corrupt government was as natural as snow in winter or flowers in the springtime, but Arthur was genuinely horrified by it. These days we remember Arthur as a warlord, as the shining man in polished armour who carried a sword into legend, but he would have wanted to be remembered as nothing but a good, honest and just ruler. The sword gave him power, but he gave that power to the law. ‘It isn’t an important kingdom,’ he continued, ‘but it will make endless trouble if we don’t put it right.’ He was thinking aloud, trying to anticipate every obstacle that lay between this night after battle and his dream of a peaceful united Britain. ‘The ideal answer,’ he said, ‘would be to divide it between Gwent and Powys.’

‘Then why not do that?’ I asked.

‘Because I have promised Siluria to Lancelot,’ he said in a voice that brooked no contradiction. I said nothing, but just touched Hywelbane’s hilt so that the iron would protect my soul from the evil things of this night. I was gazing southwards to where the dead lay like a tide-rill by the tree fence where my men had fought the enemy all that long day.

There had been so many brave men in that fight, but no Lancelot. In all the years that I had fought for Arthur, and in all the years that I had been acquainted with Lancelot, I had yet to see Lancelot in the shield-wall. I had seen him pursuing beaten fugitives, and seen him lead captives off to parade them before an excited crowd, but I had never seen him in the hard, sweaty, clanging press of struggling shield-walls. He was the exiled King of Benoic, unthroned by the horde of Franks that had erupted out of Gaul to sweep his father’s kingdom into oblivion, and not once, so far as I knew, had he ever carried a spear against a Frankish war-band, yet bards throughout the length and breadth of Britain sang of his bravery. He was Lancelot, the King without land, the hero of a hundred fights, the sword of the Britons, the handsome lord of sorrows, the paragon, and all of that high reputation was made by song and none of it, so far as I knew, with a sword. I was his enemy, and he mine, but both of us were friends of Arthur and that friendship kept our enmity in an awkward truce.

Arthur knew my hostility. He touched my elbow so that we both walked on south towards the tide-rill of the dead. ‘Lancelot is Dumnonia’s friend,’ he insisted, ‘so if Lancelot rules Siluria then we shall have nothing to fear from it. And if Lancelot marries Ceinwyn, then Powys will support him too.’

There, it was said, and now my hostility was brittle with anger, yet still I said nothing against Arthur’s scheme. What could I say? I was the son of a Saxon slave, a young warrior with a band of men but no land, and Ceinwyn was a Princess of Powys. She was called seren, the star, and she shone in a dull land like a spark of the sun fallen into mud. She had been betrothed to Arthur, but had lost him to Guinevere, and that loss had brought on the war that had just ended in the slaughter of Lugg Vale. Now, for peace, Ceinwyn must marry Lancelot, my enemy, while I, a mere nothing, was in love with her. I wore her brooch and I carried her image in my thoughts. I had even sworn an oath to protect her, and she had not spurned the oath. Her acceptance had filled me with an insane hope that my love for her was not hopeless, but it was. Ceinwyn was a Princess and she must marry a King, and I was a slave-born spearman and would marry where I could.

So I said nothing about my love for Ceinwyn, and Arthur, who was disposing of Britain in this night after his victory, suspected nothing. And why should he? If I had confessed to him that I was in love with Ceinwyn he would have thought it as outrageous an ambition as a dunghill rooster wanting to mate with an eagle. ‘You know Ceinwyn, don’t you?’ he asked me.

‘Yes, Lord.’

‘And she likes you.’ he said, only half as a question.

‘So I dare to think,’ I said truthfully, remembering Ceinwyn’s pale, silvery beauty and loathing the thought of it being given into Lancelot’s handsome keeping. ‘She likes me well enough,’ I went on, ‘to have told me she has no enthusiasm for this marriage.’

‘Why should she?’ Arthur asked. ‘She’s never met Lancelot. I don’t expect enthusiasm from her, Derfel, just obedience.’

I hesitated. Before the battle, when Tewdric had been so desperate to end the war that threatened to ruin his land, I had gone on a peace mission to Gorfyddyd. The mission had failed, but I had talked with Ceinwyn and told her of Arthur’s hope that she should marry Lancelot. She had not rejected the idea, but nor had she welcomed it. Back then, of course, no one believed Arthur could defeat Ceinwyn’s father in battle, but Ceinwyn had considered that unlikely possibility and had asked me to request one favour of Arthur if he should win. She wanted his protection, and I, falling so hard in love with her, translated that request as a plea that she should not be forced into a marriage she did not want. I told Arthur now that she had begged his protection. ‘She’s been betrothed too often, Lord,’ I added, ‘and too often disappointed, and I think she wants to be left alone for a time.’

‘Time!’ Arthur laughed. ‘She hasn’t got time, Derfel. She’s nearly twenty! She can’t stay unmarried like a cat that won’t catch mice. And who else can she marry?’ He walked on a few paces. ‘She has my protection,’ he said, ‘but what better protection could she want than to be married to Lancelot and placed on a throne? And what about you?’ he asked suddenly.

‘Me, Lord?’ For a moment I thought he was proposing that I should marry Ceinwyn and my heart leapt.

‘You’re nearly thirty,’ he said, ‘and it’s time you were married. We’ll see to it when we’re back in Dumnonia, but for now I want you to go to Powys.’

‘Me, Lord? Powys?’ We had just fought and defeated Powys’s army and I could not imagine that anyone in Powys would welcome an enemy warrior.

Arthur gripped my arm. ‘The most important thing in the next few weeks, Derfel, is that Cuneglas is acclaimed King of Powys. He thinks no one will challenge him, but I want to be sure. I want one of my men in Caer Sws to be a witness to our friendship. Nothing more. I just want any challenger to know that he will have to fight me as well as Cuneglas. If you’re there and if you’re seen to be his friend then that message will be clear.’

‘So why not send a hundred men?’ I asked.

‘Because then it will look as if we’re imposing Cuneglas on Powys’s throne. I don’t want that. I need him as a friend, and I don’t want him returning to Powys looking like a defeated man. Besides,’ he smiled, ‘you’re as good as a hundred men, Derfel. You proved that yesterday.’

I grimaced, for I was always uncomfortable with extravagant compliments, but if the praise meant that I was the right man to be Arthur’s envoy in Powys then I was happy, for I would be close to Ceinwyn again. I still treasured the memory of her touch on my hand, just as I treasured the brooch she had given me so many years before. She had not married Lancelot yet, I told myself, and all I wanted was a chance to indulge my impossible hopes. ‘And once Cuneglas is acclaimed,’ I asked, ‘what do I do then?’

‘You wait for me,’ Arthur said. ‘I’m coming to Powys as soon as I can, and once we’ve settled the peace and Lancelot is safely betrothed, we’ll go home. And next year, my friend, we’ll lead the armies of Britain against the Saxons.’ He spoke with a rare relish for the business of making war. He was good at fighting, and he even enjoyed battle for the unleashed thrills it gave his usually so careful soul, but he never sought war if peace was available because he mistrusted the uncertainties of battle. The vagaries of victory and defeat were too unpredictable, and Arthur hated to see good order and careful diplomacy abandoned to the chances of battle. But diplomacy and tact would never defeat the invading Saxons who were spreading westwards across Britain like vermin. Arthur dreamed of a well-ordered, lawfully governed, peaceful Britain and the Saxons were no part of that dream.

‘We’ll march in the spring?’ I asked him.

‘When the first leaves show.’

‘Then I would ask one favour of you first.’

‘Name it,’ he said, delighted that I should want something in return for helping to give him victory.

‘I want to march with Merlin, Lord,’ I said.

He did not answer for a while. He just stared down at the damp ground where a sword lay with its blade bent almost double. Somewhere in the dark a man moaned, cried out, then was silent. ‘The Cauldron,’ Arthur said at last, his voice heavy.

‘Yes, Lord,’ I said. Merlin had come to us during the battle and pleaded that both sides should abandon the fight and follow him on a quest to find the Cauldron of Clyddno Eiddyn. The Cauldron was the greatest Treasure of Britain, the magical gift of the old Gods, and it had been lost for centuries. Merlin’s life was dedicated to retrieving those Treasures, and the Cauldron was his greatest prize. If he could find the Cauldron, he told us, he could restore Britain to her rightful Gods. Arthur shook his head. ‘Do you really think the Cauldron of Clyddno Eiddyn has stayed hidden all these years?’ he asked me. ‘Through all the Roman years? It was taken to Rome, Derfel, and it was melted down for pins or brooches or coins. There is no Cauldron!’

‘Merlin says there is, Lord,’ I insisted.

‘Merlin has listened to old women’s tales,’ Arthur said angrily. ‘Do you know how many men he wants to take on this search for his Cauldron?’

‘No, Lord.’

‘Eighty, he told me. Or a hundred. Or, better still, two hundred! He won’t even say where the Cauldron is, he just wants me to give him an army and let him march it away to some wild place. Ireland, maybe, or the Wilderness. No!’ He kicked the bent sword, then prodded a finger hard into my shoulder.

‘Listen, Derfel, I need every spear I can muster next year. We’re going to finish the Saxons once and for ever, and I can’t lose eighty or a hundred men to the chase of a bowl that disappeared nearly five hundred years ago. Once Aelle’s Saxons are defeated you can chase this nonsense if you must. But I tell you it is a nonsense. There is no Cauldron.’ He turned and began to walk back to the fires. I followed, wanting to argue with him, but I knew I could never persuade him for he would need every spear he could muster if he was to defeat the Saxons, and he would do nothing now that would weaken his chances of victory in the spring. He smiled at me as if to compensate for his harsh refusal of my request.

‘If the Cauldron does exist,’ he said, ‘then it can stay hidden another year or two. But in the meantime, Derfel, I plan to make you rich. We shall marry you to money.’ He slapped my back. ‘One last campaign, my dear Derfel, one last great slaughter, then we shall have peace. Pure peace. We won’t need any cauldrons then.’ He spoke exultingly. That night, among the dead, he really did see peace coming.

We walked towards the fires that lay around the Roman house where Ceinwyn’s father, Gorfyddyd, lay dead. Arthur was happy that night, truly happy, for he saw his dream coming true. And it all seemed so easy. There would be one more war, then peace for evermore. Arthur was our warlord, the greatest warrior in Britain, yet that night after battle, among the shrieking souls of the smoke-wreathed dead, all he wanted was peace. Gorfyddyd’s heir, Cuneglas of Powys, shared Arthur’s dream. Tewdric of Gwent was an ally, Lancelot would be given the kingdom of Siluria and together with Arthur’s Dumnonian army the united kings of Britain would defeat the invading Saxons. Mordred, under Arthur’s protection, would grow to assume Dumnonia’s throne and Arthur would retire to enjoy the peace and prosperity his sword had given Britain.

Thus Arthur disposed the golden future.

But he did not reckon on Merlin. Merlin was older, wiser and subtler than Arthur, and Merlin had smelt the Cauldron out. He would find it, and its power would spread through Britain like a poison. For it was the Cauldron of Clyddno Eiddyn. It was the Cauldron that broke men’s dreams. And Arthur, for all his practicality, was a dreamer.

In Caer Sws the leaves were heavy with the last ripeness of summer.

I had travelled north with King Cuneglas and his defeated men and so I was the only Dumnonian present when the body of King Gorfyddyd was burned on Dolforwyn’s summit. I saw the flames of his balefire gust huge in the night as his soul crossed the bridge of swords to its shadowbody in the Otherworld. The fire was surrounded by a double ring of Powys’s spearmen who carried flaming torches that swayed together as they sang the Death Lament of Beli Mawr. They sang for a long time and the sound of their voices echoed from the near hills like a choir of ghosts. There was much sorrow in Caer Sws. So many in the land had been made widows and orphans, and on the morning after the old King was burned and when his balefire was still sending a pyre of smoke towards the northern mountains, there was still more sorrow when the news of Ratae’s fall arrived. Ratae had been a great fortress on Powys’s eastern frontier, but Arthur had betrayed it to the Saxons to buy their peace while he fought against Gorfyddyd. None in Powys knew of Arthur’s treachery yet and I did not tell them. I did not see Ceinwyn for three days, for they were the days of mourning for Gorfyddyd and no women went to the balefire. Instead the women of Powys’s court wore black wool and were shut up inside the women’s hall. No music was played in the hall, only water was given for drink and their only food was dry bread and a thin gruel of oats. Outside the hall the warriors of Powys gathered for the new King’s acclamation and I, obedient to Arthur’s orders, tried to detect whether any man would challenge Cuneglas’s right to the throne, but I heard no whisper of opposition. At the end of the three days the door of the women’s hall was thrown open. A maidservant appeared in the doorway and scattered rue on the hall’s threshold and steps, and a moment later a billow of smoke gushed from the door and we knew the women were burning the old king’s marriage bedding. The smoke swirled from the hall’s door and windows, and only when the smoke had dissipated did Helledd, now Queen of Powys, come down the steps to kneel before her husband, King Cuneglas of Powys. She wore a dress of white linen which, when Cuneglas raised her, showed muddy marks where she had knelt. He kissed her, then led her back into the hall. Black-cloaked Iorweth, Powys’s chief Druid, followed the King into the women’s hall, while outside, ringing the hall’s wooden walls in ranks of iron and leather, the surviving warriors of Powys watched and waited.

They waited while a choir of children chanted the love duet of Gwydion and Aranrhod, the Song of Rhiannon, and then every long verse of Gofannon’s March to Caer Idion, and it was only when that last song was finished that Iorweth, now robed in white and carrying a black staff tipped with mistletoe, came to the door and announced that the days of mourning were at last over. The warriors cheered and broke from the ranks to seek their own women. Tomorrow Cuneglas would be acclaimed on Dolforwyn’s summit and if any man wanted to challenge his right to rule Powys then the acclamation would provide that chance. It would also be my first glimpse of Ceinwyn since the battle. Next day I stared at Ceinwyn as Iorweth performed the rites of acclamation. She stood watching her brother and I gazed at her in a kind of wonder that any woman could be so lovely. I am old now, so perhaps my old man’s memory exaggerates Princess Ceinwyn’s beauty, but I do not think so. She was not called the seren, the star, for nothing. She was of average height, but very slightly built and that slenderness gave her an appearance of fragility that was, I later learned, a deception, for Ceinwyn had, above all things, a will of steel. Her hair, like mine, was fair, only hers was pale gold and sun-bright while mine was more like the colour of dirty straw. Her eyes were blue, her demeanour was demure and her face as sweet as honey from a wild comb. That day she was dressed in a blue linen gown that was trimmed with the black-flecked silver-white fur of a winter stoat, the same dress she had worn when she had touched my hand and taken my oath. She caught my eye once and smiled gravely and I swear my heart checked in its beating.

The rites of Powys’s kingship were not unlike our own. Cuneglas was paraded about Dolforwyn’s stone circle, he was given the symbols of kingship, and then a warrior declared him King and dared any man present to challenge the acclamation. The challenge was answered by silence. The ashes of the great balefire still smoked beyond the circle to show that a King had died, but the silence about the stones was proof that a new King reigned. Then Cuneglas was presented with gifts. Arthur, I knew, would be bringing his own magnificent present, but he had given me Gorfyddyd’s war sword that had been found on the battlefield and I now gave it back to Gorfyddyd’s son as a token of Dumnonia’s wish to have peace with Powys.

After the acclamation there was a feast in the lone hall that stood on Dolforwyn’s summit. It was a meagre feast, richer in mead and ale than in food, but it was a chance for Cuneglas to tell the warriors his hopes for his reign.

He spoke first of the war that had just ended. He named the dead of Lugg Vale, and promised his men that those warriors had not died in vain. ‘What they achieved,’ he said, ‘is peace between the Britons. A peace between Powys and Dumnonia.’ That caused some growls among the warriors, but Cuneglas stilled them with a raised hand. ‘Our enemy,’ he said, and his voice was suddenly hard, ‘is not Dumnonia. Our enemy is the Saxon!’ He paused, and this time no one growled in dissent. They just waited in silence and watched their new King, who was in truth no great warrior, but a good and honest man. Those qualities seemed obvious on his round, guileless young face to which he had vainly attempted to add dignity by growing long, plaited moustaches that hung to his breast. He might be no warrior, but he was shrewd enough to know that he had to offer these warriors the chance of war, for only by war could a man earn glory and wealth. Ratae, he promised them, would be retaken and the Saxons punished for the horrors they had inflicted on its inhabitants. Lloegyr, the Lost Lands, would be reclaimed from the Saxons, and Powys, once the mightiest of Britain’s kingdoms, would once again stretch from the mountains to the German Sea. The Roman towns would be rebuilt, their walls raised to glory again and the roads repaired. There would be farmland, booty and Saxon slaves for every warrior in Powys. They applauded that prospect, for Cuneglas was offering his disappointed chieftains the rewards that such men always sought from their kings. But, he went on after raising a hand to still the cheering, the wealth of Lloegyr would not be reclaimed by Powys alone. ‘Now,’ he warned his followers, ‘we march alongside the men of Gwent and beside the spearmen of Dumnonia. They were my father’s enemies, but they are my friends and that is why my Lord Derfel is here.’ He smiled at me. ‘And that is why,’ he continued,

‘under the next full moon, my dear sister will pledge her betrothal to Lancelot. She will rule as Queen in Siluria and the men of that country will march with us, and with Arthur and with Tewdric, to rid the land of Saxons. We shall destroy our true enemy. We shall destroy the Sais!’

This time the cheers were unstinted. He had won them over. He was offering them the wealth and power of old Britain and they clapped their hands and stamped their feet to show their approval. Cuneglas stood for a while, letting the acclamation continue, then he just sat and smiled at me as if he recognized how Arthur would have approved of all he had just said.

I did not stay on Dolforwyn for the drinking that would go on all night, but instead walked back to Caer Sws behind the ox-drawn wagon that carried Queen Helledd, her two aunts and Ceinwyn. The royal ladies wanted to be back in Caer Sws by sunset and I went with them, not because I felt unwelcome among Cuneglas’s men, but because I had found no chance to talk with Ceinwyn. So, like a moonstruck calf, I joined the small guard of spearmen who escorted the wagon homewards. I had dressed carefully that day, wanting to impress Ceinwyn, and so I had cleaned my mail armour, brushed the mud from my boots and cloak, then woven my long fair hair into a loose plait that hung down my back. I wore her brooch on my cloak as a sign of my allegiance to her. I thought she would ignore me, for all through that long walk back to Caer Sws she sat in the wagon and stared away from me, but at last, as we turned the corner and the fortress came into sight, she turned and dropped off the wagon to wait for me beside the road. The escorting spearmen moved aside to let me walk beside her. She smiled as she recognized the brooch, but made no reference to it. ‘We were wondering, Lord Derfel,’ she said instead, ‘what brought you here.’

‘Arthur wanted a Dumnonian to witness your brother’s acclamation. Lady,’ I answered.

‘Or did Arthur want to be sure that he would be acclaimed?’ she asked shrewdly.

‘That too,’ I admitted.

She shrugged. ‘There’s no one else who could be King here. My father made certain of that. There was a chieftain called Valerin who might have challenged Cuneglas for the kingship, but we hear Valerin died in the battle.’

‘Yes, Lady, he did,’ I said, but I did not add that it had been I who had killed Valerin in single combat by the ford at Lugg Vale. ‘He was a brave man, and so was your father. I am sorry for you that he’s dead.’

She walked in silence for a few paces as Helledd, Powys’s Queen, watched us suspiciously from the ox-cart. ‘My father,’ Ceinwyn said after a while, ‘was a very bitter man. But he was always good to me.’

She spoke bleakly, but shed no tears. Those tears had all been wept already and now her brother was King and Ceinwyn faced a new future. She hitched up her skirts to negotiate a muddy patch. There had been rain the night before and the clouds to the west promised more soon. ‘So Arthur comes here?’ she asked.

‘Any day now, Lady.’

‘And brings Lancelot?’ she asked.

‘I would think so.’

She grimaced. ‘The last time we met, Lord Derfel, I was to marry Gundleus. Now it is to be Lancelot. One King after another.’

‘Yes, Lady,’ I said. It was an inadequate, even a stupid answer, but I had been struck by the exquisite nervousness that ties a lover’s tongue. All I ever wanted was to be with Ceinwyn, but when I found myself at her side I could not say what was in my soul.

‘And I am to be Queen of Siluria,’ Ceinwyn said, without any relish at the prospect. She stopped and gestured back down the Severn’s wide valley. ‘Just past Dolforwyn,’ she told me, ‘there’s a little hidden valley with a house and some apple trees. And when I was a little girl I always used to think the Otherworld was like that valley; a small, safe place where I could live, be happy and have children.’ She laughed at herself and began walking again. ‘All across Britain there are girls who dream of marrying Lancelot and being a Queen in a palace, and all I want is a small valley with its apple trees.’

‘Lady,’ I said, nerving myself to say what I really wanted to say, but she immediately guessed what was on my mind and touched my arm to hush me.

‘I must do my duty. Lord Derfel,’ she said, warning me to guard my tongue.

‘You have my oath,’ I blurted out. It was as near to a confession of love as I was capable of at that moment.

‘I know,’ she said gravely, ‘and you are my friend, are you not?’

I wanted to be more than a friend, but I nodded. ‘I am your friend, Lady.’

‘Then I will tell you,’ she said, ‘what I told my brother.’ She looked up at me, her blue eyes very serious. ‘I don’t know that I want to marry Lancelot, but I have promised Cuneglas that I will meet him before I make up my mind. I must do that, but whether I shall marry him, I don’t know.’ She walked in silence for a few paces and I sensed she was debating whether to tell me something. Finally she decided to trust me. ‘After I saw you last,’ she went on, ‘I visited the priestess at Maesmwyr and she took me to the dream cave and made me sleep on the bed of skulls. I wanted to discover my fate, you see, but I don’t remember having any dreams at all. But when I woke the priestess said that the next man who wanted to marry me would marry the dead instead.’ She gazed up at me. ‘Does that make sense?’

‘None, Lady,’ I said and touched the iron on Hywelbane’s hilt. Was she warning me? We had never spoken of love, but she must have sensed my yearning.

‘It makes no sense to me either,’ she confessed, ‘so I asked Iorweth what the prophecy meant and he told me I should stop worrying. He said the priestess talks in riddles because she’s incapable of talking sense. What I think it means is that I should not marry at all, but I don’t know. I only know one thing, Lord Derfel. I will not marry lightly.’

‘You know two things, Lady,’ I said. ‘You know my oath holds.’

‘I know that too’ she said, then smiled at me again. ‘I’m glad you’re here, Lord Derfel.’ And with those words she ran on ahead and scrambled back into the ox-cart, leaving me to puzzle over her riddle and to find no answer that could give my soul peace.

Arthur came to Caer Sws three days later. He came with twenty horsemen and a hundred spearmen. He brought bards and harpists. He brought Merlin, Nimue and gifts of the gold taken from the dead in Lugg Vale, and he also brought Guinevere and Lancelot.

I groaned when I saw Guinevere. We had won a victory and made peace, yet even so I thought it cruel of Arthur to bring the woman for whom he had spurned Ceinwyn. But Guinevere had insisted on accompanying her husband and so she arrived in Caer Sws in an ox-drawn wagon that was furnished with furs, hung with dyed linens and draped with green branches to signify peace. Queen Klaine, Lancelot’s mother, rode in the cart with Guinevere, but it was Guinevere, not the Queen, who commanded attention. She stood as the cart pulled slowly through Caer Sws’s gate and she remained standing as the oxen drew her to the door of Cuneglas’s great hall, where once she had been an unwanted exile and to which she now came like a conqueror. She wore a robe of linen dyed gold, she wore gold about her neck and on her wrists, while her springing red hair was trapped by a circle of gold. She was pregnant, but the pregnancy did not show beneath the precious gold linen. She looked like a Goddess.

Yet if Guinevere looked a Goddess, Lancelot rode into Caer Sws like a God. Many folk assumed he must be Arthur for he looked magnificent on a white horse draped with a pale linen cloth that was studded with small golden stars. He wore his white-enamelled scale armour, his sword was scabbarded in white and a long white cloak, lined with red, hung from his shoulders. His dark, handsome face was framed by the gilded edges of his helmet that was now crested with a pair of spread swan’s wings instead of the sea-eagle wings he had worn in Ynys Trebes. People gasped when they saw him and I heard the whispers hurry through the crowd that this was not Arthur after all, but King Lancelot, the tragic hero of the lost kingdom of Benoic and the man who would marry their own Princess Ceinwyn. My heart sank at the sight of him, for I feared his magnificence would dazzle Ceinwyn. The crowd hardly noticed Arthur, who wore a leather jerkin and a white cloak and seemed embarrassed to be in Caer Sws at all. That night there was a feast. I doubt Cuneglas could have felt much welcome for Guinevere, but he was a patient, sensible man who, unlike his father, did not choose to take offence at every imagined slight, and so he treated Guinevere like a Queen. He poured her wine, served her food and bent his head to talk with her. Arthur, seated on Guinevere’s other side, beamed with pleasure. He always looked happy when he was with his Guinevere, and there must have been a keen pleasure for him to see her treated with such ceremony in the very same hall where he had first glimpsed her standing among the lesser folk at the back of the crowd.

Arthur paid most of his attentions to Ceinwyn. Everyone in the hall knew how he had spurned her once and how he had broken their betrothal to marry the penniless Guinevere, and many men of Powys had sworn they could never forgive Arthur that slight, yet Ceinwyn forgave him and made her forgiveness obvious. She smiled on him, laid a hand on his arm and leaned close to him, and later in the feast, when mead had melted away all the old hostilities, king Cuneglas took Arthur’s hand, then his sister’s, and clasped them together in his and the hall cheered to see that sign of peace. An old insult was laid to rest. A moment later, in another symbolic gesture, Arthur took Ceinwyn’s hand and led her to a seat that had been left empty beside Lancelot. There were more cheers. I watched stony-faced as Lancelot stood to receive Ceinwyn, then as he sat beside her and poured her wine. He took a heavy golden bracelet from his wrist and presented it to her, and though Ceinwyn made a show of refusing the generous gift, she at last slipped it onto her arm where the gold gleamed in the rush light. The warriors on the hall floor demanded to see the bracelet and Ceinwyn coyly lifted her arm to show the heavy band of gold. I alone did not cheer. I sat as the sound thundered about me and as a heavy rain beat on the thatch. She had been dazzled, I thought, she had been dazzled. The star of Powys had fallen before Lancelot’s dark and elegant beauty.

I would have left the hall there and then to carry my misery into the rainswept night, but Merlin had been stalking the floor of the hall. At the beginning of the feast he had been seated at the high table but he had left it to move among the warriors, stopping here and there to listen to a conversation or to whisper in a man’s ear. His white hair was drawn back from his tonsure into a long plait that he had bound in a black ribbon, while his long beard was similarly plaited and bound. His face, dark as the Roman chestnuts that were such a delicacy in Dumnonia, was long, deeply lined and amused. He was up to mischief, I thought, and I had shrunk down in my place so that he would not work that mischief on me. I loved Merlin like a father, but I was in no mood for more riddles. I just wanted to be as far from Ceinwyn and Lancelot as the Gods would let me go.

I waited until I thought Merlin was on the far side of the hall and that it was safe for me to leave without him spotting me, but it was just at that moment that his voice whispered in my ear. ‘Were you hiding from me, Derfel?’ he asked, then he gave an elaborate groan as he settled on the floor beside me. He liked pretending that his great age had made him feeble, and he made a great play of massaging his knees and groaning at the pain in his joints. Then he took the horn of mead out of my hand and drained it.

‘Behold the virgin Princess,’ he said, gesturing with the empty horn towards Ceinwyn, ‘going to her grisly fate. Let’s see now.’ He scratched between the plaits of his beard as he thought about his next words. ‘A half month till the betrothal? Marriage a week or so later, then a handful of months till the child kills her. No chance of a baby coming out of those little hips without splitting her in two.’ He laughed. ‘It will be like a pussy cat giving birth to a bullock. Very nasty, Derfel.’ He peered at me, enjoying my discomfort.

‘I thought,’ I responded sourly, ‘that you had made Ceinwyn a charm of happiness?’

‘So I did,’ he said blandly, ‘but what of it? Women like having babies and if Ceinwyn’s happiness consists of being ripped into two bloody halves by her firstborn then my charm will have worked, will it not?’ He smiled at me.

‘ “She will never be high,”‘ I said, quoting Merlin’s prophecy that he had uttered in this very hall not a month before, ‘ “and she will never be low, but she will be happy.”‘

‘What a memory for trivia you do have! Isn’t the mutton awful? Under-cooked, you see. And it’s not even hot! I can’t abide cold food.’ Which did not stop him stealing a portion from my dish. ‘Do you think that being Queen of Siluria is high?’

‘Isn’t it?’ I asked sourly.

‘Oh, dear me, no. What an absurd idea! Siluria’s the most wretched place on earth, Derfel. Nothing but grubby valleys, stony beaches and ugly people.’ He shuddered. ‘They burn coal instead of wood and most of the folk are black as Sagramor as a result. I don’t suppose they know what washing is.’ He pulled a piece of gristle from his teeth and tossed it to one of the hounds that scavenged among the feasters. ‘Lancelot will soon be bored by Siluria! I can’t see our gallant Lancelot enduring those ugly, coal-blackened slugs for very long, so, if she survives childbirth, which I doubt, poor little Ceinwyn will be left all alone with a heap of coal and a squalling baby. That’ll be the end of her!’ He seemed pleased at the prospect. ‘Have you ever noticed, Derfel, how you find a young woman in the height of her beauty, with a face to snatch the very stars out of their heavens, and a year later you discover her stinking of milk and infant shit and you wonder how you could ever have found her beautiful? Babies do that to women, so look on her now, Derfel, look on her now, for she will never again be so lovely.’

She was lovely, and worse, she seemed happy. She was robed in white this night and about her neck was hung a silver star looped on a silver chain. Her golden hair was bound by a fillet of silver, and silver raindrops hung from her ears. And Lancelot, that night, looked as striking as Ceinwyn. He was said to be the handsomest man in Britain, and so he was if you liked his dark, thin, long, almost reptilian face. He was dressed in a black coat striped with white, wore a gold torque at his throat and had a circle of gold binding his long black hair that was oiled smooth against his scalp before cascading down his back. His beard, trimmed to a sharp point, was also oiled.

‘She told me,’ I said to Merlin, and knowing as I spoke that I revealed too much of my heart to that wicked old man, ‘that she isn’t certain about marrying Lancelot.’

‘Well, she would say that, wouldn’t she?’ Merlin answered carelessly, beckoning to a slave who was carrying a dish of pork towards the high table. He scooped a handful of ribs into the lap of his grubby white robe and sucked greedily on one of them. ‘Ceinwyn,’ he went on when he had sucked most of the rib bare, ‘is a romantic fool. She somehow convinced herself she could marry where she liked, though the Gods alone know why any girl should think that! Now, of course,’ he said with his mouth full of pork,

‘everything changes. She’s met Lancelot! She’ll be dizzy with him by now. Maybe she won’t even wait for the marriage? Who knows? Maybe, this very night, in the secrecy of her chamber, she’ll tup the bastard dry. But probably not. She’s a very conventional girl.’ He said the last three words disparagingly.

‘Have a rib,’ he offered. ‘It’s time you were married.’

‘There is no one I want to marry,’ I said sulkily. Except Ceinwyn, of course, but what hope did I have against Lancelot?

‘Marriage has nothing to do with wanting,’ Merlin said scornfully. ‘Arthur thought it was, and what a fool for women Arthur is! What you want, Derfel, is a pretty girl in your bed, but only a fool thinks the girl and the wife have to be the same creature. Arthur thinks you should marry Gwenhwyvach.’ He said the name carelessly.

‘Gwenhwyvach!’ I said too loudly. She was Guinevere’s younger sister and was a heavy, dull, pale-skinned girl whom Guinevere could not abide. I had no particular reason to dislike Gwenhwyvach, but nor could I imagine marrying such a drab, soulless and unhappy girl.

‘And why ever not?’ Merlin asked in pretended outrage. ‘A good match, Derfel. What are you, after all, but the son of a Saxon slave? And Gwenhwyvach is a genuine Princess. No money, of course, and uglier than the wild sow of Llyffan, but think how grateful she’ll be!’ He leered at me. ‘And consider Gwenhwyvach’s hips, Derfel! No danger there of a baby getting stuck. She’ll spit the little horrors out like greased pips!’

I wondered if Arthur had really proposed such a marriage, or whether it was Guinevere’s idea? More likely it was Guinevere. I watched her as she sat arrayed in gold beside Cuneglas and the triumph on her face was unmistakable. She looked uncommonly beautiful that night. She was ever the most striking-looking woman in Britain, but on that rainy feast night in Caer Sws she seemed to glow. Maybe that was because of her pregnancy, but the likelier explanation was that she was revelling in her ascendancy over these people who had once dismissed her as a penniless exile. Now, thanks to Arthur’s sword, she could dispose of these people just as her husband disposed of their kingdoms. It was Guinevere, I knew, who was Lancelot’s chief supporter in Dumnonia, and Guinevere who had made Arthur promise Lancelot Siluria’s throne, and Guinevere who had decided that Ceinwyn should be Lancelot’s bride. Now, I suspected, she wanted to punish me for my hostility to Lancelot by making her inconvenient sister into my lumpen bride.

‘You look unhappy, Derfel,’ Merlin provoked me.

I did not rise to the provocation. ‘And you, Lord?’ I asked. ‘Are you happy?’

‘Do you care?’ he asked airily.

‘I love you, Lord, like a father,’ I said.

He hooted at that, then half choked on a sliver of pork, but was still laughing when he recovered. ‘Like a father! Oh, Derfel, what an absurdly emotional beast you are. The only reason I raised you was because I thought you were special to the Gods, and maybe you are. The Gods do sometimes choose the strangest creatures to love. So tell me, loving would-be son, does your filial love extend to service?’

‘What service, Lord?’ I asked, though I knew well enough what he wanted. He wanted spearmen to go and seek the Cauldron.

He lowered his voice and leaned closer to me, though I doubt anyone could have heard our conversation in the loud, drunken hall. ‘Britain,’ he said, ‘suffers from two sicknesses, but Arthur and Cuneglas recognize only one.’

‘The Saxons.’

He nodded. ‘But Britain without the Saxons will still be diseased, Derfel, for we risk losing the Gods. Christianity spreads taster than the Saxons, and Christians are a bigger offence to our Gods than any Saxon. If we don’t restrain the Christians then the Gods will desert us utterly, and what is Britain without her Gods? But if we harness the Gods and restore them to Britain, then the Saxons and the Christians will both vanish. We attack the wrong disease, Derfel.’

I glanced at Arthur who was listening intently to something Cuneglas was saying. Arthur was not an irreligious man, but he carried his beliefs lightly and bore no hatred in his soul for men and women who believed in other Gods, yet Arthur, I knew, would hate to hear Merlin talk of fighting against the Christians. ‘And no one listens to you, Lord?’ I asked Merlin.

‘Some,’ he said grudgingly, ‘a few, one or two. Arthur doesn’t. He thinks I’m an old fool on the edge of senility. But what about you, Derfel? Do you think I’m an old fool?’

‘No, Lord.’

‘And do you believe in magic, Derfel?’

‘Yes, Lord,’ I said. I had seen magic work, but I had seen it fail too. Magic was difficult, but I believed in it.

Merlin leaned even closer to my ear. ‘Then be at Dolforwyn’s summit this night, Derfel,’ he whispered,

‘and I will grant you your soul’s desire.’

A harpist struck the chord that would summon the bards for the singing. The warriors’ voices died away as a chill wind gusted rain through the open door and flickered the small flames of the tallow candles and the grease-soaked rush lights. ‘Your soul’s desire,’ Merlin whispered again, but when I looked to my left he had somehow vanished.

And in the night the thunder growled. The Gods were abroad and I was summoned to Dolforwyn. I left the feast before the giving of gifts, before the bards sang and before the drunken warriors’ voices swelled in the haunting Song of Nwyfre. I heard the song far behind me as I walked alone down the river valley where Ceinwyn had told me of her visit to the bed of skulls and of the strange prophecy that made no sense.

I wore my armour, but carried no shield. My sword, Hywelbane, was at my side and my green cloak was about my shoulders. No man walked the night lightly, for night belonged to ghouls and spirits, but I had been summoned by Merlin so I knew I would be safe.

My path was made easy for there was a road that led east from the ramparts towards the southern edge of the range of hills where Dolforwyn lay. It was a long walk, four hours in the wet dark, and the road was black as pitch, but the Gods must have wanted me to arrive for I neither lost the road, nor met any dangers in the night.

Merlin, I knew, could not be far ahead of me, and though I was two lifetimes younger than he, I neither caught up with him nor even heard him. I just heard the fading song and afterwards, when the singing had faded into the dark, I listened to the rill of the river running over the stones and the patter of rain falling in the leaves and the scream of a hare caught by a weasel and the shriek of a badger calling for her mate. I passed two crouching settlements where the dying glow of fires showed through the low openings beneath the bracken thatch. From one of those huts a man’s voice called out in challenge, but I called to him that I was travelling in peace and he quieted his barking dog. I left the road to find the narrow track that twisted up Dolforwyn’s flank and I feared the darkness would make me lose my way under the oaks that grew thick on the hill’s side, but the rain clouds thinned to let a wan moonlight drift through the wet heavy leaves and show me the stony path that climbed sunwise up the royal hill. No man lived here. It was a place of oaks, stone and mystery. The path led from the trees into the wide open space of the summit where the lone feasting hall stood and where the circle of standing stones marked where Cuneglas had been acclaimed. This summit was Powys’s most sacred place, yet for most of the year it stood deserted, used only at high feasts and at times of great solemnity. Now, in the wan moonlight, the hall stood dark and the hilltop seemed empty. I paused at the edge of the oaks. A white owl flew above me, its stubby body rushing on short wings close to my helmet’s wolf-tailed crest. The owl was an omen, but I could not tell whether the omen was good or evil and I was suddenly afraid. Curiosity had drawn me here, but now I sensed the danger. Merlin would not offer me my soul’s desire for nothing, and that meant I was here to make a choice, and it was a choice I suspected I would not want to make. Indeed, I feared it so much that I almost turned back into the dark of the trees, but then a pulse on the scar of my left hand held me in place. The scar had been put there by Nimue and whenever the scar throbbed I knew that my fate was gone from my choosing. I was oath-sworn to Nimue. I could not go back.

The rain had stopped and the clouds were tattered. There was a cold wind beating the treetops, but no rain. It was still dark. Dawn could not be far off, but as yet no hint of light rose across the eastern hills. There was only the glimmering wash of moonlight that turned the stones of Dolforwyn’s royal circle into silvered shapes in the dark.

I walked towards the stone circle and the sound of my heart seemed louder than the footfall of my heavy boots. Still no one appeared and for a moment I wondered if this was some elaborate jest on Merlin’s part, but then, in the centre of the stone ring, where the single stone of Powys’s kingship lay, I saw a gleam that was brighter than any reflection of misted moonlight from rain-glossed rock. I moved closer, my heart thumping, then stepped between the circle’s stones and saw that the moonlight was reflecting from a cup. A silver cup. A small silver cup which, when I came close to the royal stone, I saw was filled with a dark, moon-glossed liquid.

‘Drink, Derfel,’ Nimue’s voice said in a whisper that barely carried above the sound of the wind in the oaks. ‘Drink.’

I turned, looking for her, but could see no one. The wind lifted my cloak and flapped some loose thatch on the hall’s roof. ‘Drink, Derfel,’ Nimue’s voice said again, ‘drink.’

I looked up into the sky and prayed to Lleullaw that he would preserve me. My left hand, that was now throbbing in pain, was clasped tight about Hywelbane’s hilt. I wanted to do the safe thing, and that, I knew, was to walk away and go back to the warmth of Arthur’s friendship, but the misery in my soul had brought me to this cold bare hill and the thought of Lancelot’s hand resting on Ceinwyn’s slender wrist made me look down to the cup.

I lifted it, hesitated, then drained it.

The liquid tasted bitter so that I shuddered when it was all gone. The rank taste stayed in my mouth and throat as I carefully laid the cup back on the king’s stone.

‘Nimue?’ I called almost beseechingly, but there was no answer except for the wind in the trees.

‘Nimue!’ I called again, for my head was reeling now. The clouds were churning black and grey, and the moon was splintering into spikes of silvered light that slashed up from the distant river and shattered in the thrashing dark of the twisting trees. ‘Nimue!’ ‘ called as my knees gave way and as my head spun in lurid dreams. I knelt by the royal stone that suddenly loomed as large as a mountain before me, then I then fell forward so heavily that my sprawling arm sent the empty cup flying. I flit sick, but no vomit would come, there were just dreams, terrible dreams, shrieking ghouls of nightmare that screamed inside my head. I was crying, I was sweating and my muscles were twitching in uncontrollable spasms. Then hands seized my head. My helmet was dragged from my hair, then a forehead was pressed against mine. It was a cool white forehead and the nightmares skittered away to be replaced by a vision of a long, naked white body with slender thighs and small breasts. ‘Dream, Derfel,’ Nimue soothed me, her hands stroking my hair, ‘dream, my love, dream.’

I was crying helplessly. I was a warrior, a Lord of. Dumnonia, beloved of Arthur and so in his debt after the last battle that he would grant me land and wealth beyond my dreams, yet now I wept like an orphaned child. My soul’s desire was Ceinwyn, but Ceinwyn was being dazzled by Lancelot and I thought I could never know happiness again.

‘Dream, my love,’ Nimue crooned, and she must have swept a black cloak over both our heads for suddenly the grey night vanished and I was in a silent darkness with her arms about my neck and her face pressed close to mine. We knelt, cheek beside each other’s cheek, with my hands shuddering spasmodically and helplessly on the cool skin of her bare thighs. I let my body’s twitching weight lean on her slender shoulders and there, in her arms, the tears ended, the spasms faded and suddenly I was calm. No vomit edged my throat, the ache in my legs was gone and I felt warm. So warm that the sweat still poured off me. I did not move, I did not want to move, but just let the dream come. At first it was a wondrous dream for it seemed I had been given the wings of a great eagle and I was flying high above a land I did not know. Then I saw it was a terrible land, broken by great chasms and by tall mountains of jagged rock down which small streams cascaded white towards dark peaty lakes. The mountains seemed to have no end, nor any refuge, for as I coasted above them on the wings of my dream, I saw no houses, no huts, no fields, no flocks, no herds, no souls, but only a wolf running between the crags and the bones of a deer lying in a thicket. The sky above me was as grey as a sword, the mountains below were dark as dried blood and the air beneath my wings as cold as a knife in the ribs.

‘Dream, my love,’ Nimue murmured, and in the dream I swept low on my wide wings to see a road twisting between the dark hills. It was a road of beaten earth, broken by rocks, that picked its cruel way from valley to valley, sometimes climbing to bleak passes before it dropped again to the bare stones of another valley floor. The road edged black lakes, cut through shadowed chasms, skirted snow-streaked hills, but always led towards the north. How it was the north I did not know, but this was a dream in which knowledge needs no reason.

The dream wings dropped me down to the road’s surface and suddenly I was flying no longer, but climbing the road towards a pass in the hills. The slopes on either side of the pass were steep black slabs of slate running with water, but something told me the road’s end lay just beyond the black pass and that if I could just keep walking on my tired legs I would cross the crest and find my soul’s desire at the farther side.

I was panting now, my breath coming in agonized gasps as I dreamed my way up the last few paces of the road and there, suddenly, at the summit, I saw light and colour and warmth. For the road dropped beyond the pass to a coastline where there were trees and fields, and beyond the coast was a glittering sea in which an island lay, and in the island, shining in the sudden sun, was a lake. ‘There!’ I spoke aloud for I knew the island was my goal, but just when it seemed I was given a renewed energy to run down the road’s last miles and plunge into that sunlit sea, a ghoul sprang into my path. It was a black thing in black armour with a mouth spitting black slime and a black-bladed sword twice as long as Hywelbane in its black-clawed hand. It screamed a challenge at me. And I screamed too, and my body stiffened in Nimue’s embrace.

Her arms gripped my shoulders. ‘You have seen the Dark Road, Derfel,’ she whispered, ‘you have seen the Dark Road.’ And suddenly she pulled away from me and the cloak was whipped from my back and I fell forward onto Dolforwyn’s wet grass as the wind swirled cold about me. I lay there for long minutes. The dream had passed and I wondered what the Dark Road had to do with my soul’s desire. Then I jerked aside and vomited, and after that my head felt clear again and I could see the fallen silver cup beside me. I picked it up, rocked back onto my haunches and saw that Merlin was watching me from the far side of the royal stone. Nimue, his lover and priestess, was beside him, her thin body swathed in a vast black cloak, her black hair held in a ribbon and her golden eye shining in the moonlight. The eye in that socket had been prised out by Gundleus, and for that injury he had paid a thousandfold.

Neither spoke, but just watched as I spat the last vomit from my mouth, cuffed at my lips, shook my head, then tried to stand. My body was still weak, or else my skull was still reeling, for I could not raise myself and so, instead, I knelt beside the stone and leaned on my elbows. Small spasms still made me twitch from time to time. ‘What did you make me drink?’ I asked, putting the silver cup back on the rock.

‘I made you drink nothing,’ Merlin answered. ‘You drank of your own free will, Derfel, just as you came here of your own free will.’ His voice, that had been so mischievous in Cuneglas’s hall, was now cold and distant. ‘What did you see?’

‘The Dark Road,’ I answered obediently.

‘It lies there,’ Merlin said, and pointed north into the night.

‘And the ghoul?’ I asked.

‘Is Diwrnach,’ he said.

I closed my eyes for I knew now what he wanted. ‘And the island,’ I said, opening my eyes again, ‘is Ynys Mon?’

‘Yes,’ Merlin said. ‘The blessed isle.’

Before the Romans came and before the Saxons were even dreamed of, Britain was ruled by the Gods and the Gods spoke to us from Ynys Mon, but the island had been ravaged by the Romans who had cut down its oaks, destroyed its sacred groves and slaughtered its guardian Druids. That Black Year had occurred more than four hundred years before this night, yet Ynys Mon was still sacred to the few Druids who, like Merlin, tried to restore the Gods to Britain. But now the blessed island was a part of the kingdom of Lleyn, and Lleyn was ruled by Diwrnach, the most terrible of all the Irish Kings who had crossed the Irish Sea to take British land. Diwrnach was said to paint his shields with human blood. There was no King in all Britain more cruel or more feared, and it was only the mountains that hemmed him in and the smallness of his army that kept him from spreading his terror south through Gwynedd. Diwrnach was a beast that could not be killed; a creature that lurked at the dark edge of Britain and, by common consent, he was best left unprovoked. ‘You want me,’ I said to Merlin, ‘to go to Ynys Mon?’

‘I want you to come with us to Ynys Mon,’ he said, indicating Nimue, ‘with us and a virgin.’

‘A virgin?’ I asked.

‘Because only a virgin, Derfel, can find the Cauldron of Clyddno Eiddyn. And none of us, I think, qualifies,’ he added the last words sarcastically.

‘And the Cauldron,’ I said slowly, ‘is on Ynys Mon.’ Merlin nodded and I shuddered to think of such an errand. The Cauldron of Clyddno Eiddyn was one of the thirteen magical Treasures of Britain that had been dispersed when the Romans had laid waste Ynys Mon, and Merlin’s final ambition of his long life was to reassemble the Treasures, but the Cauldron was his real prize. With the Cauldron, he claimed, he could control the Gods and destroy the Christians, and that was why, with a bitter tasting mouth and a belly rank with sourness, I was kneeling on a wet hilltop in Powys. ‘My job,’ I said to Merlin, ‘is to fight the Saxons.’

‘Fool!’ Merlin snapped. ‘The war against the Sais is lost unless we regain the Treasures.’

‘Arthur doesn’t agree.’

‘Then Arthur is a fool as great as you. What do the Saxons matter, fool, if our Gods have deserted us?’

T am sworn to Arthur’s service,’ I protested.

‘You are sworn to my bidding too,’ Nimue said, holding up her left hand to show the scar that matched mine.

‘But I want no man on the Dark Road,’ Merlin said, ‘who does not come willingly. You must choose your loyalty, Derfel, but I can help you choose.’

He swept the cup off the rock and put in its place a heap of the rib bones that he had taken from Cuneglas’s hall. He knelt, picked up one bone and placed it in the centre of the royal stone. ‘That is Arthur,’ he said, ‘and this,’ he took another bone, ‘is Cuneglas, and this,’ he laid a third bone so that it made a triangle with the first two, ‘we shall speak of later. This,’ he laid a fourth bone across one of the triangle’s corners, ‘is Tewdric of Gwent, and this is Arthur’s alliance with Tewdric, and this is his alliance with Cuneglas.’ The second triangle was thus formed on top of the first and the two now resembled a crude, six pointed star. ‘This is Elmet,’ he began the third layer that was parallel with the first, ‘and this is Siluria, and this bone,’ he held up the last, ‘is the alliance of all those kingdoms. There.’ He leaned back and gestured at the precarious tower of bones standing at the stone’s centre. ‘You see, Derfel, Arthur’s careful scheme, though I tell you, I promise you, that without the Treasures the scheme will tail.’

He fell silent. I stared at the nine bones. All of them, except for the mysterious third bone, were still hung with scraps of meat, tendon and gristle. It was just that third bone that had been scraped clean and white. I touched it very gently with my finger, taking care not to disturb the fragile balance of the squat tower. ‘And what is the third bone?’ I asked.

Merlin smiled. ‘The third bone, Derfel,’ he said, ‘is the marriage between Lancelot and Ceinwyn.’ He paused. ‘Take it.’

I did not move. To take the third bone would be to collapse Arthur’s fragile network of alliances that were his best, indeed his only hope of defeating the Saxons.

Merlin sneered at my reluctance, then he took hold of the third bone, but he did not pull it free. ‘The Gods hate order,’ he snarled at me. ‘Order, Derfel, is what destroys the Gods, so they must destroy order.’ He pulled the bone out and the pile immediately collapsed into chaos. ‘Arthur must restore the Gods, Derfel,’ Merlin said, ‘if he is to bring peace to all Britain.’ He held the bone out to me. ‘Take it.’

I did not move.

‘It is just a pile of bones,’ Merlin said, ‘but this bone, Derfel, is your soul’s desire.’ He held the clean bone towards me. ‘This bone is Lancelot’s marriage to Ceinwyn. Snap this bone in two, Derfel, and the marriage will never happen. But leave this bone whole, Derfel, and your enemy will take your woman to his bed and maul her like a dog.’ He thrust the bone towards me again, and again I did not take it. ‘You think your love for Ceinwyn isn’t written all over your face?’ Merlin asked derisively. ‘Take it! Because I, Merlin of Avalon, grant you, Derfel, power of this bone.’

I took it, the Gods help me, but I took it. What else could I do? I was in love and I took that cleansed bone and I placed it in my pouch.

‘It won’t help you,’ Merlin mocked me, ‘unless you break it.’

‘It may not help me anyway,’ I said, at last discovering that I could stand.

‘You are a fool, Derfel,’ Merlin said, ‘But you are a fool who is good with a sword and that is why I need you if we’re to walk the Dark Road.’ He stood. ‘It’s your choice now. You can break the bone and Ceinwyn will come to you, that I promise, but you will then be sworn to the Cauldron’s quest. Or you can marry Gwenhwyvach and waste your life battering Saxon shields while the Christians connive to take Dumnonia. I leave the choice to you, Derfel. Now close your eyes.’

I closed my eyes and dutifully kept them closed for a long time, but at last, when no more instructions were given, I opened them.

The hilltop was empty. I had heard nothing, but Merlin, Nimue, the eight bones and the silver cup were all gone. Dawn showed in the east, the birds were loud in the trees and I had a clean-picked bone in my pouch.

I walked downhill to the road beside the river, but in my head I saw the other road, the Dark Road that led to Diwrnach’s lair, and I was frightened.

We hunted boar that morning and Arthur deliberately sought my company as we walked out of Caer Sws. ‘You left early last night, Derfel,’ he greeted me.

‘My belly, Lord,’ I said. I did not want to tell him the truth, that I had been with Merlin, for then he would have suspected that I had not yet abandoned the Cauldron’s quest. It was better to lie. ‘I had a sour belly,’ I explained.

He laughed. ‘I never know why we call them feasts,’ he said, ‘for they’re nothing but an excuse to drink.’ He paused to wait for Guinevere, who liked to hunt and who was dressed this morning in boots and leather trews that were strapped tight to her long legs. She hid her pregnancy beneath a leather jerkin over which she wore a green cloak. She had brought a brace of her beloved deerhounds and she handed me their leashes so that Arthur could carry her through the ford that lay beside the old fortress. Lancelot offered the same courtesy to Ceinwyn who cried out in evident delight as Lancelot swept her into his arms. Ceinwyn was also dressed in men’s clothes, but hers were not cut close and subtle like Guinevere’s. Ceinwyn had probably borrowed whatever hunting clothes her brother did not want and the baggy, over-long garments made her look boyish and young beside Guinevere’s sophisticated elegance. Neither woman carried a spear, but Bors, Lancelot’s cousin and his champion, carried a spare weapon in case Ceinwyn wanted to join a kill. Arthur had insisted that the pregnant Guinevere should not carry a spear. ‘You must take care today,’ he said as he restored her to her feet on the Severn’s southern bank.

‘You worry too much,’ she said, then took the hounds’ leashes from me and pushed a hand through her thick, springing red hair as she turned back to Ceinwyn. ‘Become pregnant,” she said, ‘and men think you’re made of glass.’ She fell into step beside Lancelot, Ceinwyn and Cuneglas, leaving Arthur to walk beside me towards the leafy valley where Cuneglas’s huntsmen had reported plenty of game. There might have been fifty of us hunters altogether, mostly warriors, though a handful of women had chosen to come and two score of servants brought up the rear. One of those servants sounded a horn to tell the huntsmen at the valley’s far end that it was time to drive the game down towards the river and we hunters hefted our long, heavy boar spears as we spread out into a line. It was a cold late summer’s day, cold enough to cloud our breath, but the rain had cleared and the sun shone on fallow fields laced with a morning mist. Arthur was in high spirits, revelling in the day’s beauty, his own youth and the prospect of a hunt. ‘One more feast,’ he said to me, ‘then you can go home and rest.’

‘One more feast?’ I asked dully, my mind fuddled with tiredness and from the lingering effects of whatever Merlin and Nimue had given me to drink on Dolforwyn’s peak. Arthur clapped my shoulder. ‘Lancelot’s betrothal, Derfel. Then back to Dumnonia. And to work!’

He sounded delighted at the prospect and he enthusiastically told me his plans for the coming winter. There were four broken Roman bridges that he wanted rebuilt, then the kingdom’s stonemasons would be sent to finish the royal palace at Lindinis. Lindinis was the Roman town close to Caer Cadarn, the place of Dumnonia’s royal acclamations, and Arthur wanted to make it the new capital. ‘There are too many Christians in Durnovaria,’ he said, though he hastily, and typically, added that he had nothing personal against Christians.

‘It’s just, Lord,’ I said drily, ‘that they have something against you.’

‘Some do,’ he admitted. Before the battle, when Arthur’s cause had seemed utterly lost, a party opposed to Arthur had grown bold in Dumnonia and that party had been led by the Christians, the same Christians who had the guardianship of Mordred. The immediate cause of their hostility had been a loan that Arthur had forced from the church to pay for the campaign that ended in Lugg Vale, and that loan had sparked a bitter enmity. It was odd, I thought, how the church preached the merits of poverty, but never forgave a man for borrowing its money.

‘I wanted to talk to you of Mordred,’ Arthur said, explaining why he had sought my company on this fine morning. ‘In ten years,’ Arthur went on, ‘he’ll be old enough to take the throne. That’s not long, Derfel, not long at all, and he needs to be raised well in those ten years. I le must be taught letters, he must learn to use a sword and he must learn responsibility.’ I nodded agreement, though not with any enthusiasm. The five-year-old Mordred would doubtless learn all the things Arthur wanted, but I did not see what business it was of mine. Arthur had other ideas. ‘I want you to be his guardian,’ he said, surprising me.

‘Me!’ I exclaimed.

‘Nabur cares more about his own advancement than he does about Mordred’s character,’ Arthur said. Nabur was the Christian magistrate who was the child King’s present guardian, and it was Nabur who had plotted most vigorously to destroy Arthur’s power; Nabur and, of course, Bishop Sansum.

‘And Nabur is no soldier,’ Arthur went on. ‘I pray that Mordred will rule in peace, Derfel, but he needs the skills of war, all kings do, and I can think of no one better than you to train him.’

‘Not me,’ I protested. ‘I’m too young!’

Arthur laughed at that objection. ‘The young should be raised by the young, Derfel,’ he said. A distant horn sounded to signal that game had been started from the valley’s end. We hunters entered the trees and stepped over the tangles of briar and the dead trunks that were thick with fungi. We advanced slowly now, listening for the terrifying sound of a boar crashing through the brush. ‘Besides,’ I went on, ‘my place is in your shield-wall, not in Mordred’s nursery.’

‘You’ll still be in my shield-wall. You think I would lose you, Derfel?’ Arthur said with a grin. ‘I don’t want you tied to Mordred, I just want him in your household. I need him to be raised by an honest man.’

I shrugged that compliment away, then thought guiltily of the clean, unbroken bone in my pouch. Was it honest, I wondered, to use magic to change Ceinwyn’s mind? I looked at her, and she glanced my way and gave me a shy smile. ‘I have no household,’ I said to Arthur.

‘But you will, and soon,’ he said. Then he held up a hand and I froze, listening to the sounds ahead of us. Something heavy was trampling in the trees and we both instinctively crouched with our spears held a few inches above the ground, but then we saw that the frightened beast was a fine stag with good antlers and we relaxed as the animal pounded past. ‘We’ll hunt him tomorrow, maybe,’ Arthur said, watching the stag run past. ‘Give your hounds a run in the morning!’ he shouted to Guinevere. She laughed and came down the hill towards us, her hounds straining at their leashes. ‘I should like that,’ she said. Her eyes were bright and her face flushed by the cold. ‘The hunting’s better here than in Dumnonia,’ she said.

‘But not the land,’ Arthur said to me. ‘There’s an estate north of Durnovaria,’ he went on, ‘that is Mordred’s by right and I plan to make you its tenant. I’ll grant you other land, too, for your own, but you can make a hall on Mordred’s land and raise him there.’

‘You know the estate,’ Guinevere said. ‘It’s the one north of Gyllad’s holding.’

‘I know it,’ I said. The estate had good river land for crops and fine uplands for sheep. ‘But I’m not sure I know how to raise a child,’ I grumbled. The horns sounded loud ahead and the huntsmen’s hounds were baying. Cheers sounded far to our right, signifying that someone had found quarry, though our part of the wood was still empty. A small stream tumbled to our left and the wooded ground climbed to our right. The rocks and twisted tree roots were thick with moss.

Arthur dismissed my fears. ‘You won’t raise Mordred,’ he said, ‘but I do want him raised in your hall, with your servants, your manners, your morals and your judgments.’

‘And,’ Guinevere added, ‘your wife.’

A snapping of a twig made me look uphill. Lancelot and his cousin Bors were there, both standing in front of Ceinwyn. Lancelot’s spear shaft was painted white and he wore tall leather boots and a cloak of supple leather. I looked back to Arthur. ‘The wife, Lord,’ I said, ‘is news to me.’

He clasped my elbow, the boar hunt forgotten. ‘I plan to appoint you Dumnonia’s champion, Derfel,’

he said.

‘The honour is above me, Lord,’ I said cautiously, ‘besides, you are Mordred’s champion.’

‘Prince Arthur,’ Guinevere said, for she liked to call him Prince even though he was bastard born, ‘is already chief of the Council. He can’t be champion as well, not unless he’s expected to do all Dumnonia’s work?’

‘True, Lady,’ I said. I was not averse to the honour, for it was a high one, though there was a price. In battle I would have to tight whatever champion presented himself for single combat, but in peace it would mean wealth and status far above my present rank. I already had the title of Lord and the men to uphold that rank and the right to paint my own device on these men’s shields, but I shared these honours with two score other Dumnonian war leaders. To be the King’s champion would make me the foremost warrior of Dumnonia, though how any man could claim that status while Arthur lived, I could not see. Nor, indeed, while Sagramor lived. ‘Sagramor,’ I said carefully, ‘is a greater warrior than I, Lord Prince.’ With Guinevere present I had to remember to call him Prince once in a while, though it was a title he disliked.

Arthur waved my objection aside. ‘I am making Sagramor Lord of the Stones,’ he said, ‘and he wants nothing more.’ The lordship of the Stones made Sagramor into the man who guarded the Saxon frontier and I could well believe that the black-skinned, dark-eyed Sagramor would be well content with such a belligerent appointment. ‘You, Derfel,’ he prodded my chest, ‘will be the champion.’

‘And who,’ I asked drily, ‘will be the champion’s wife?’

‘My sister Gwenhwyvach,’ Guinevere said, watching me closely.

I was grateful that I had been forewarned by Merlin. ‘You do me too much honour, Lady,’ I said blandly.

Guinevere smiled, satisfied that my words implied acceptance. ‘Did you ever think, Derfel, that you would marry a Princess?’

‘No, Lady,’ I said. Gwenhwyvach, like Guinevere, was indeed a Princess, a Princess of Henis Wyren, though Henis Wyren was no more. That sad kingdom was now called Lleyn and was ruled by the dark Irish invader, King Diwrnach.

Guinevere yanked the leashes to subdue her excited hounds. ‘You can be betrothed when we return to Dumnonia,’ she said. ‘Gwenhwyvach has agreed.’

‘There is one obstacle, Lord,’ I said to Arthur.

Guinevere yanked on the leashes again, quite unnecessarily, but she hated all opposition and so she took out her frustration on the hounds instead of on me. She did not dislike me at that time, but nor did she particularly like me either. She knew of my aversion for Lancelot, and that doubtless prejudiced her against me, but she would not have thought my dislike significant, for she doubtless dismissed me as merely one of her husband’s war leaders; a tall, dull, flaxen-haired man who lacked the civilized graces that Guinevere so valued. ‘An obstacle?’ Guinevere asked me dangerously.

‘Lord Prince,’ I said, insisting on talking to Arthur and not to his wife, ‘I am oath-sworn to a lady.’ I thought of the bone in my pouch. ‘I have no claim on her, nor can I expect anything from her, but if she does claim me then I am obligated to her.’

‘Who?’ Guinevere demanded immediately.

‘I can’t say, Lady.’

‘Who?’ Guinevere insisted again.

‘He doesn’t need to say,’ Arthur defended me. He smiled. ‘How long can this lady claim your loyalty?’

‘Not long, Lord,’ I said, ‘only days now.’ For once Ceinwyn was betrothed to Lancelot then I could consider my oath to her voided.

‘Good,’ he said vigorously, and smiled at Guinevere as though inviting her to share his pleasure, but Guinevere was scowling instead. She detested Gwenhwyvach, finding her graceless and boring, and she desperately wanted to marry her sister out of her life. ‘If all goes well,’ Arthur said, ‘you can be married in Glevum at the same time that Lancelot marries Ceinwyn.’

‘Or are you demanding these few days,’ Guinevere asked acidly, ‘to conjure up reasons why you should not marry my sister?’

‘Lady,’ I said earnestly, ‘it would be an honour to marry Gwenhwyvach.’ That, I think, was the truth, for Gwenhwyvach would doubtless prove an honest wife, though whether I would prove a good husband was another matter, for my only reason for marrying Gwenhwyvach would be the high rank and great wealth she would bring as her dowry; but those, for most men, were the purpose of marriage. And if I could not have Ceinwyn, what did it matter who I married? Merlin ever warned us against confusing love and marriage, and though the advice was cynical, there was truth there. I was not expected to love Gwenhwyvach, just to marry her, and her rank and dowry were my rewards for fighting that long bloody day in Lugg Vale. If those rewards were tinged with Guinevere’s mockery, they were still a rich gift. ‘I will marry your sister gladly,’ I promised Guinevere, ‘so long as the keeper of my oath does not call on me.’

‘I pray she does not,’ Arthur said with a smile, then whipped round as a shout sounded uphill. Bors was crouched with his spear. Lancelot was beside him, but was glancing down the slope towards us, perhaps worried that the animal would escape through the gap between us. Arthur gently pushed Guinevere back, then gestured for me to climb the hill and plug the gap.

‘Two of them!’ Lancelot called to us.

‘One will be a sow,’ Arthur called, then ran a few paces upstream before starting to climb uphill.

‘Where?’ he asked. Lancelot pointed with his white-shafted spear, but I could still see nothing in the bushes.

‘There!’ Lancelot said petulantly, prodding his spear towards a tangle of briars. Arthur and I climbed another few feet and then at last we could see the boar deep inside the undergrowth. He was a big old beast with yellow tusks, small eyes and humps of muscle under his dark scarred hide. That muscle could move him at lightning speed and make him hook his sword sharp tusks with a fatal skill. We had all seen men die from tusk wounds, and nothing made a boar more dangerous than to be cornered with a sow. All hunters prayed for a boar charging in open ground so that they could use the beast’s own speed and bulk to drive the spear into his body. Such a confrontation demanded nerve and skill, but not nearly so much nerve as when a man had to charge the boar.

‘Who saw him first?’ Arthur asked.

‘My Lord King did.’ Bors indicated Lancelot.

‘Then he’s yours, Lord King.’ Arthur graciously waived the honour of the kill to Lancelot.

‘He is my gift to you, Lord,’ Lancelot answered. Ceinwyn was standing behind him, biting her lower lip and with eyes wide. She had taken the spare spear from Bors, not because she hoped to use it, but to spare him the burden, and she held the weapon nervously.

‘Put the hounds on him!’ Guinevere joined us. Her eyes were bright and her face animated. She was, I think, often bored in Dumnonia’s great palaces and the hunting field gave her an excitement she craved.

‘You’ll lose both dogs,’ Arthur warned her. ‘This pig knows how to fight.’ He moved cautiously forward, judging how best to provoke the beast, then he stepped sharply ahead and beat hard down on the bushes with his spear as though to offer the boar a path out of its sanctuary. The beast grunted, but did not move, not even when the spear blade flashed down within inches of its snout. The sow was behind the boar, watching us.

‘It’s done this before,’ Arthur said happily.

‘Let me take him. Lord,’ I said, suddenly anxious for him.

‘You think I’ve lost my skill?’ Arthur asked with a smile. He beat the bushes again, but the briars would not lie flat, nor would the boar move. ‘The Gods bless you.’ Arthur said to the beast, then he shouted a challenge and jumped into the tangle of thorns. He leapt to one side of the path he had crudely beaten and as he landed he rammed the spear hard forward, aiming its glittering blade at the boar’s left flank just forward of its shoulder.

The boar’s head seemed to twitch, only a slight twitch, but it was enough to deflect the spear blade off the tusk so that it slashed a bloody and harmless cut down the animal’s flank, and then it charged. A good boar can come from a still stance into instant madness with its head down and tusks ready to gut upwards, and this beast was already past Arthur’s spearhead when it charged and Arthur was trapped by the brambles.

I shouted to distract the boar and plunged my own spear into its belly. Arthur was on his back, his spear abandoned, and the boar was on top of him. The hounds howled and Guinevere was shouting at us to help. My spear was deep in the beast’s belly and its blood spurted up to my hands as I levered up and over to roll the wounded beast off my Lord. The creature weighed more than two full sacks of grain, and its muscles were like iron ropes that twitched my spear. I gripped hard and pushed up, but then the sow charged and swept my feet away from under me. I fell, and my weight pulled the spear shaft down and thus brought the boar back onto Arthur’s belly.

Arthur had somehow gripped both the beast’s tusks and, using all his strength, was now forcing its head away from his chest. The sow vanished, plunging downhill towards the stream. ‘Kill him!’ Arthur shouted, though he was half laughing as well. He was just inches from death, but he was loving the moment. ‘Kill him!’ he called again. The boar’s back legs were thrusting, its spittle was spattering Arthur’s face and its blood was soaking his clothes.

I was on my back, my face lacerated with thorns. I scrambled to my feet and reached for my jerking, twisting spear that was still buried in the great brute’s belly, but then Bors plunged a knife into the boar’s neck and I saw the enormous strength of the animal begin to ebb as Arthur managed to force the squat, stinking, bloody head away from his ribs. I seized my spear and twisted the blade, searching for the animal’s life blood deep in its guts as Bors stabbed a second time. The boar suddenly pissed on Arthur, gave one last desperate lunge of its huge neck and then abruptly slumped down. Arthur was awash in its blood and urine, and half buried under its bulk.

He cautiously let go of the tusks, then dissolved into helpless laughter. Bors and I took a tusk each and, with a concerted heave, hauled the corpse away from Arthur. One of the tusks had caught in Arthur’s jerkin and it ripped the cloth as we tugged it away. We dropped the beast into the brambles, then helped Arthur to his feet. The three of us stood grinning, our clothes muddied and torn and covered with leaves, twigs and the blood of the boar. ‘I’ll have a bruise there,’ Arthur said, tapping his chest. He turned to Lancelot, who had not moved to help during the struggle. There was the briefest pause, then Arthur bowed his head. ‘You gave me a noble gift, Lord King,’ he said, ‘and I took it most ignobly.’ He wiped his eyes. ‘But I enjoyed it all the same. And we shall all enjoy it at your betrothal feast.’ He looked at Guinevere and saw that she was pale, almost trembling, and immediately he crossed to her. ‘Are you ill?’

‘No, no,’ she said, and she put her arms about him and leaned her head against his bloodied chest. She was crying. It was the first time I had ever seen her cry.

Arthur patted her back. ‘There was no danger, my love,’ he said, ‘no danger. I just made a hash of the killing.’

‘Are you hurt?’ Guinevere asked, pulling away from him and cuffing away her tears.

‘Only scratched.’ His face and hands were lacerated by thorns, but he was otherwise unwounded except for the bruise caused by the tusk. He stepped away from her, picked up his spear and gave a whoop. ‘I haven’t been put on my back like that in a dozen years!’

King Cuneglas came running, worried about his guests, and the huntsmen arrived to truss and carry the corpse away. They must all have noted the comparison between Lancelot’s unstained clothes and our dishevelled and bloody state, but no one remarked on it. We were all excited, pleased to have survived and eager to share the story of Arthur holding the brute away from his body by its tusks. The story spread and the sound of men’s laughter rang loud among the trees. Lancelot alone did not laugh. ‘We must find you a boar now, Lord King,’ I said to him. We were standing a few paces from the excited crowd that had gathered to watch as the huntsmen gralloched the beast to give Guinevere’s hounds a meal of its guts.

Lancelot gave me a sidelong, considering glance. He disliked me every scrap as much as I disliked him, but suddenly he smiled. ‘A boar,’ he said, ‘would be better than a sow, I think.’

‘A sow?’ I asked, smelling an insult.

‘Didn’t the sow charge you?” he asked, then opened his eyes guilelessly wide. ‘Surely you don’t think I was referring to your marriage!’ He offered me an ironic bow. ‘I must congratulate you, Lord Derfel!

To marry Gwenhwyvach!’

I forced my anger down, and made myself look into his narrow mocking face with its delicate beard, dark eyes, and long hair oiled as black and shining as a raven’s wing. ‘And I must congratulate you, Lord King, on your betrothal.’

‘To Seren,’ he said, ‘the star of Powys.’ He gazed at Ceinwyn who stood with her hands clasped to her face as the huntsmen’s knives ripped out the long coils of the boar’s intestines. She looked so young with her bright hair drawn up at the nape of her neck. ‘Doesn’t she look charming?’ Lancelot asked me in a voice like the purr of a cat. ‘So vulnerable. I never believed the stories of her beauty, for who would expect to find such a jewel among Gorfyddyd’s whelps? But she is beautiful, and I am so very fortunate.’

‘Yes, Lord King, you are.’

He laughed and turned away. He was a man in his glory, a King come to take his bride, and he was also my enemy. But I had his bone in my pouch. I touched it, wondering if the struggle with the boar had broken the rib, but it was still whole, still hidden and just waiting for my pleasure. Cavan, my second-in-command, came to Caer Sws on the eve of Ceinwyn’s betrothal and brought with him forty of my spearmen. Galahad had sent them back, reckoning that his work in Siluria could be completed by the twenty remaining men. The Silurians, it seems, had glumly accepted their country’s defeat and there had been no unrest at the news of their King’s death, merely a docile submission to the exactions of the victors. Cavan told me that Oengus of Demetia, the Irish King who had brought Arthur victory at Lugg Vale, had taken his allotted portion of slaves and treasure, stolen as much again, and had then gone home, and the Silurians were evidently happy enough that the renowned Lancelot was now to be their King. ‘And I reckon the bastard’s welcome to the place,’ Cavan said when he found me in Cuneglas’s hall where I spread my blanket and took my meals. He scratched at a louse in his beard.

‘Scrubby place, Siluria.’

‘They breed good warriors,’ I said.

‘Fighting to get away from home, I wouldn’t wonder.’ He sniffed. ‘What clawed your face, Lord?’

‘Thorns. Fighting a boar.’

‘I thought you might have got married when I wasn’t watching you,’ he said, ‘and that was her wedding gift.’

‘I am to be married,’ I told him as we walked out of the hall into Caer Sws’s sunlight, and I described Arthur’s proposal to make me Mordred’s champion and his own brother-in-law. Cavan was pleased at the news of my imminent enrichment for he was an Irish exile who had sought to turn his skills with spear and sword into a fortune in Uther’s Dumnonia, but somehow the fortune had kept slipping away across the throwboard. He was twice my age, a squat man, broad-shouldered, grey-bearded and with hands thick with the warrior rings we forged from the weapons of defeated enemies. He was delighted that my marriage would mean gold and he was tactful about the bride who would bring that metal. ‘She isn’t a beauty like her sister,’ he said.

‘True,’ I admitted.

‘In fact,’ he said, abandoning tact, ‘she’s as ugly as a sack of toads.’

‘She is plain,’ I conceded.

‘But plain ones make the best wives, Lord,’ he declared, never having been married himself, though never lonely either. ‘And she’ll bring us all wealth,’ he added happily, and that, of course, was the reason I would marry poor Gwenhwyvach. My common sense could not put faith in the pork rib in my pouch, and my duty to my men was to reward them for their fidelity, and those rewards had been few in the last year. They had lost virtually all their possessions at the fall of Ynys Trebes and had then struggled against Gorfyddyd’s army at Lugg Vale; now they were tired, they were impoverished and no men had ever deserved more of their lord.

I greeted my forty men who were waiting to be assigned quarters. I was glad to see Issa among them, for he was the best of my spearmen: a young farm boy of huge strength and undying optimism who protected my right side in battle. I embraced him, then expressed my regrets that I had no gifts for them.

‘But our reward is coming soon,’ I added, then glanced at the two dozen girls they must have attracted in Siluria, ‘though I’m glad to see most of you have already found some rewards for yourselves.’

They laughed. Issa’s girl was a pretty dark-haired child of perhaps fourteen summers. He introduced her to me. ‘Scarach, Lord.’ He named her proudly.

‘Irish?’ I asked her.

She nodded. ‘I was a slave. Lord, to Ladwys.’ Scarach spoke the tongue of Ireland; a language like ours, but different enough, like her name, to mark her race. I guessed she had been captured by Gundleus’s men in a raid on King Oengus’s lands in Demetia. Most Irish slaves came from such settlements on Britain’s west coast though none, I suspected, were ever captured from Lleyn. No one but a fool ventured uninvited into Diwrnach’s territory.

‘Ladwys!’ I said. ‘How is she?’ Ladwys had been Gundleus’s mistress, a dark, tall woman whom Gundleus had secretly married, though he had been ready enough to disown the marriage when Gorfyddyd had offered him the prospect of Ceinwyn’s hand.

‘She’s dead, Lord,’ Scarach said happily. ‘We killed her in the kitchen. I put a spit in her belly.’

‘She’s a good girl,’ Issa said eagerly.

‘Evidently,’ I said, ‘so look after her.’ His last girl had deserted him for one of the Christian missionaries who wandered Dumnonia’s roads, but somehow I doubted that the redoubtable Scarach would prove such a fool.

That afternoon, using lime from Cuneglas’s stores, my men painted a new device on their shields. The honour of carrying my own device had been granted to me by Arthur on the eve of the battle at Lugg Vale, but we had been given no time to change the shields which, till now, had all carried Arthur’s symbol of the bear. My men expected me to choose a wolf’s mask as our symbol, to echo the wolf-tails that we had begun to wear on our helmets in the forests of Benoic, but I insisted that we each painted a five-pointed star. ‘A star!’ Cavan growled in disappointment. He wanted something fierce, with claws and beak and teeth, but I insisted on the star. ‘Seren,’ I said, ‘for we are the stars of the shield-wall.’

They liked that explanation, and none suspected the hopeless romanticism that lay behind my choice. So we first laid a coat of black pitch on the round, leather-covered willow-board shields, then painted the stars in lime, using a scabbard to get the edges straight, and when the limewash had dried we applied a varnish made of pine resin and egg-white that would protect the stars from rain for a few months. ‘It’s different,’ Cavan grudgingly allowed when we admired the finished shields.

‘It’s splendid,’ I said, and that night, when I dined in the circle of warriors who ate on the floor of the hall, Issa stood behind me as shield-bearer. The varnish was still wet, but that only made the star seem brighter. Scarach served me. It was a poor meal of barley gruel, but Caer Sws’s kitchens could provide no better for they were busy preparing the next night’s great feast. Indeed the whole compound was busy with those preparations. The hall had been decorated with boughs of dusk-red beech, the floor had been swept and strewn with new rushes, and from the women’s quarters we heard tales of dresses being made and delicately embroidered. At least four hundred warriors were now in residence at Caer Sws, most of them quartered in crude shelters thrown up on the fields outside the ramparts, and the warriors’ women, children and dogs thronged the fort. Half the men belonged to Cuneglas, the other half were Dumnonians, but despite the recent war there was no trouble, not even when the news spread that Ratae had fallen to Aelle’s Saxon horde because of Arthur’s treachery. Cuneglas must have suspected that Arthur had purchased Aelle’s peace by some such means and he accepted Arthur’s oath-promise that the men of Dumnonia would extract vengeance for the dead of Powys who lay in the ashes of the captured fortress. I had seen neither Merlin nor Nimue since the night on Dolforwyn. Merlin had left Caer Sws, but Nimue, I heard, was still in the fortress and was staying hidden in the women’s quarters where, rumour said, she was much in the Princess Ceinwyn’s company. That seemed unlikely to me because Nimue and Ceinwyn were so very different. Nimue was a few years older than Ceinwyn and she was dark and intense and forever trembling on the narrow divide between madness and anger, while Ceinwyn was fair and gentle and, as Merlin had told me, so very conventional. I could not imagine that either woman had much to say to the other, and so I assumed that the rumours were false and that Nimue was with Merlin who, I believed, had gone to find the men who would carry their swords into Diwrnach’s dreaded land to seek the Cauldron.

But would I go with him? On the morning of Ceinwyn’s betrothal I walked northwards into the great oaks that lapped around Caer Sws’s wide valley. I sought a particular place and Cuneglas had told me where to find it. Issa, loyal Issa, came with me, but he had no idea what business took us into the dark, deep wood.

This land, the heart of Powys, had been lightly touched by the Romans. They had built forts here, like Caer Sws, and they had left a few roads that arrowed along the river valleys, but there were no great villas or towns like those that gave Dumnonia its gloss of a lost civilization. Nor, here in Cuneglas’s heartland, were there many Christians; the worship of the old Gods survived in Powys without the rancour that soured religion in Mordred’s realm, where Christian and pagan vied for royal favour and the right to erect their shrines in the holy places. No Roman altars had replaced Powys’s Druid groves and no Christian churches stood by its holy wells. The Romans had cut down some of the shrines, but many had been preserved and it was to one of those ancient holy places that Issa and I came in the leafy twilight of the midday forest.

It was a Druid shrine, a grove of oaks deep within a massive wood. The leaves above the shrine had yet to fade to bronze, but soon they would turn and fall onto the low stone wall that lay in a semicircle at the grove’s centre. Two niches had been made in the wall and two human skulls were set in the niches. Once there had been many such places in Dumnonia, and many more had been remade after the Romans had left. Too often, though, the Christians would come and break the skulls, pull down the drystone walls and cut down the oaks, but this shrine in Powys might have stood among these deep woods for a thousand years. Little scraps of wool had been pushed between the stones as markers for the prayers that folk offered in this grove.

It was silent in the oaks; a heavy silence. Issa watched from the trees as I walked to the centre of the semicircle where I unstrapped Hywelbane’s heavy belt.

I laid the sword on the flat stone that marked the shrine’s centre and took from my pouch the clean white rib bone that gave me power over Lancelot’s marriage. This I placed beside the sword. Last of all I put down on the stone the small golden brooch that Ceinwyn had given me so many years before. Then I lay down flat in the leaf mould.

I slept in hope of a dream that would tell me what to do, but no dream came. Maybe I should have sacrificed some bird or beast before I slept, a gift that might have provoked a God to grant me the answer I sought, but no answer came. There was just silence. I had put my sword and the power of the bone into the hands of the Gods, into the keeping of Bel and Manawydan, of Taranis and Lleullaw, but they ignored my gifts. There was only the wind in the high leaves, the scratching of squirrel claws on the oak branches and the sudden rattle of a woodpecker.

I lay still when I woke. There had been no dream, but I knew what I wanted. I wanted to take the bone and snap it in two, and if that gesture meant walking the Dark Road into Diwrnach’s kingdom, then so be it. But I also wanted Arthur’s Britain to be whole and good and true. And I wanted my men to have gold and land and slaves and rank. I wanted to drive the Saxons from Lloegyr. I wanted to hear the screams of a broken shield-wall and the blare of war horns as a victorious army pursued a shattered enemy to ruin. I wanted to march my starry shields into the flat eastern land that no free Briton had seen in a generation. And I wanted Ceinwyn.

I sat up. Issa had come to sit close beside me. He must have wondered why I stared so fixedly at the bone, but he asked no questions.

I thought of Merlin’s small, squat tower of bones that represented Arthur’s dream and wondered if that dream would really collapse if Lancelot did not marry Ceinwyn. The marriage was hardly the clasp that held Arthur’s alliance together; it was merely a convenience to give Lancelot a throne and Powys a stake in Siluria’s royal house. If the marriage never happened then the armies of Dumnonia and Gwent and Powys and Elmet would still march against the Sais. All that I knew, and all that was true, yet I also sensed that the bone could somehow jar Arthur’s dream. The moment I snapped the bone in two I became sworn to Merlin’s search, and that search promised to bring enmity to Dumnonia; the enmity of the old pagans who so hated the upstart Christian religion.

‘Guinevere,’ I suddenly said the name aloud.

‘Lord?’ Issa asked in puzzlement.

I shook my head to show that I had nothing more to say. Indeed, I had not meant to speak Guinevere’s name aloud, yet I had suddenly understood that to break the bone would do more than encourage Merlin’s campaign against the Christian God, it would also make Guinevere into my enemy. I closed my eyes. Could my Lord’s wife be an enemy? And what if she were? Arthur would still love me, and I him, and my spears and starry shields were worth more to him than all Lancelot’s fame. I stood and retrieved the brooch, the bone and the sword. Issa watched as I pulled a thread of green-dyed wool from my cloak and jammed it between the stones. ‘You were not at Caer Sws,’ I asked him, ‘when Arthur broke his betrothal to Ceinwyn?’

‘No, Lord. I heard about it, though.’

‘It was at the betrothal feast,’ I said, ‘just like the one we’ll attend tonight. Arthur was sitting at the high table with Ceinwyn beside him and he saw Guinevere at the back of the hall. She was standing in a shabby cloak with her hounds beside her and Arthur saw her there and nothing was ever the same again. The Gods alone know how many men died because he saw that head of red hair.’ I turned back to the low stone wall and saw there was an abandoned nest inside one of the mossy skulls. ‘Merlin tells me that the Gods love chaos,’ I said.

‘Merlin loves chaos,’ Issa said lightly, though there was more truth in his words than he knew.

‘Merlin loves it,’ I agreed, ‘but most of us fear chaos and that’s why we try to make order.’ I thought of the carefully ordered pile of bones. ‘But when you have order, you don’t need Gods. When everything is well ordered and disciplined then nothing is unexpected. If you understand everything,’ I said carefully,

‘then there’s no room left for magic. It’s only when you’re lost and frightened and in the dark that you call on the Gods, and they like us to call on them. It makes them feel powerful, and that’s why they like us to live in chaos.’ I was repeating the lessons of my childhood, the lessons given to us on Merlin’s Tor.

‘And now we have a choice,’ I told Issa. ‘We can live in Arthur’s well-ordered Britain or we can follow Merlin to chaos.’

‘I’ll follow you, Lord, whatever you do,’ Issa said. I do not think he understood what I was saying, but he was content to trust me anyway.

‘I wish I knew what to do,’ I confessed. How easy it would be, I thought, if the Gods just walked Britain as they used to. Then we could see them, hear them and talk to them, but now we were like blindfolded men seeking a clasp-pin in a thorn thicket. I strapped the sword back into its place, then tucked the unbroken bone safe back in the pouch. ‘I want you to give a message to the men,’ I told Issa.

‘Not to Cavan, for I’ll talk to him myself, but I want you to tell them that if anything strange happens this night, they are released from their oaths to me.’

He frowned at me. ‘Released from our oaths?’ he asked, then shook his head vigorously. ‘Not me, Lord.’

I hushed him. ‘And tell them,’ I went on, ‘that if something strange does happen, and it may not, then loyalty to my oath could mean fighting against Diwrnach.’

‘Diwrnach!’ Issa said. He spat and made the symbol against evil with his right hand.

‘Tell them that, Issa,’ I said.

‘So what might happen tonight?’ he asked me anxiously.

‘Maybe nothing,’ I said, ‘maybe nothing at all,’ because the Gods had given me no sign in the grove and I still did not know what I would choose. Order or chaos. Or neither, for maybe the bone was nothing but a piece of kitchen scrap and its breaking would do nothing except symbolize my own shattered love for Ceinwyn. But there was only one way to find out, and that was to break the bone. If I dared.

At Ceinwyn’s betrothal feast.

Of all the feasts of those late summer nights the betrothal feast of Lancelot and Ceinwyn was the most lavish. Even the Gods seemed to favour it, for the moon was full and clear, and that was a wonderful omen for a betrothal. The moon rose shortly after sunset, a silver orb that loomed huge above the peaks where Dolforwyn lay. I had wondered if the feast would be held in Dolforwyn’s hall, but Cuneglas, seeing the huge number to be fed, had decided to keep the celebrations inside Caer Sws. There were far too many guests for the King’s hall, and so only the most privileged were allowed inside its thick wooden walls. The rest sat outside, grateful that the Gods had sent a dry night. The ground was still wet from the rain earlier in the week, but there was plenty of straw for men to make dry seats. Pitch-soaked torches had been tied to stakes and, moments after the moonrise, those torches were lit so that the royal compound was suddenly bright with leaping flames. The wedding would be held in the daylight so that Gwydion, the God of light, and Belenos, the God of the sun, would grant their blessing, but the betrothal was given to the moon’s blessing. Every now and then a burning wisp from a torch would float to earth to set alight a patch of straw and there would be bellows of laughter, screaming children, barking dogs and a flurry of panic until the fire was extinguished. Over a hundred men were guests inside Cuneglas’s hall. Tapers and rush lights were clustered together to flicker weird shadows in the high, beamed thatch where the sprays of beech leaves were now mixed with the year’s first clusters of holly berries. The hall’s one table was set on the dais beneath a row of shields and each shield had a taper below it to illuminate the device painted on the leather. At the centre was Cuneglas’s royal shield of Powys with its spread-winged eagle, and on one side of the eagle was Arthur’s black bear and on the other Dumnonia’s red dragon. Guinevere’s device of a moon-crowned stag was hung next to the bear, while Lancelot’s sea-eagle flew with a fish in its claws next to the dragon. No one was present from Gwent, but Arthur had insisted that Tewdric’s black bull be hung, along with Elmet’s red horse and the fox mask of Siluria. The royal symbols marked the great alliance; the shield-wall that would batter the Saxons back to the sea.

Iorweth, Powys’s chief Druid, announced the moment when he was certain that the last rays of the dying sun had vanished into the far Irish Sea, and then the guests of honour took their places on the dais. The rest of us were already seated on the hall’s floor where men were calling for more of Powys’s famously strong mead that had been specially brewed for this night. Cheers and applause greeted the honoured guests.

Queen Elaine came first. Lancelot’s mother was dressed in blue with a gold torque at her throat and a golden chain binding the coils of her grey hair. A huge roar welcomed Cuneglas and Queen Helledd next. The King’s round face beamed with pleasure at the prospect of this night’s celebration in honour of which he had tied small white ribbons to his dangling moustaches. Arthur came in sober black, while Guinevere, following him to the dais, was splendid in her gown of pale gold linen. It was cut and stitched cunningly so that the precious fabric, skilfully dyed with soot and hive-gum, seemed to cling to her tall, straight body. Her belly barely betrayed her pregnancy and a murmur of appreciation for her beauty sounded among the watching men. Small gold scales had been sewn into the gown’s cloth so that her body appeared to glint as she slowly followed Arthur to the centre of the dais. She smiled at the lust she knew she had provoked, and that she wanted to provoke, for this night Guinevere was determined to outshine whatever Ceinwyn wore. A circlet of gold held Guinevere’s unruly red hair in place, a belt of golden chain links was looped around her waist, while in honour of Lancelot she wore at her neck a golden brooch depicting a sea-eagle. She kissed Queen Elaine on both cheeks, kissed Cuneglas on one, bobbed her head to Queen Helledd, then sat at Cuneglas’s right hand while Arthur slipped into the empty chair beside Helledd.

Two seats remained, but before either was filled Cuneglas stood and rapped the table with his fist. Silence fell, and in the silence Cuneglas mutely gestured towards the treasures that were arrayed on the edge of the dais in front of the linen hanging from the table.

The treasures were the gifts Lancelot had brought for Ceinwyn and their magnificence caused a storm of acclamation in the hall. We had all inspected the gifts and I had listened sourly as men extolled the King of Benoic’s generosity. There were torques of gold, torques of silver and torques made of a mixture of gold and silver, so many torques that they merely served as the foundation on which the greater gifts were piled. There were Roman hand mirrors, flasks of Roman glass and piles of Roman jewels. There were necklaces, brooches, ewers, pins and clasps. There was a king’s ransom in glittering metal, in enamel, coral and precious gems and all of it, I knew, had been rescued from burning Ynys Trebes when Lancelot, disdaining to carry his sword against the rampaging Franks, had fled on the first ship to escape the city’s slaughter.

The applause for the gifts was still sounding when Lancelot arrived in his glory. Like Arthur he was dressed in black, but Lancelot’s black clothes were hemmed by strips of rare gold cloth. His black hair had been oiled and sleeked back so that it lay close to his narrow skull and flat against his back. The fingers of his right hand glittered with rings of gold while his left was dull with warrior rings, none of which, I sourly assumed, he had earned in battle. Around his neck he wore a heavy gold torque with finials glinting with bright stones, and on his breast, in Ceinwyn’s honour, he wore her royal family’s symbol of the spread-winged eagle. He wore no weapons, for no man was allowed to bring a blade into a King’s hall, but he wore the enamelled sword belt that had been a gift from Arthur. He acknowledged the cheers with a raised hand, kissed his mother on the cheek, kissed Guinevere on the hand, bowed to Helledd, then sat.

The one chair remained empty. A harpist had begun to play, her plangent notes scarcely audible above the buzz of talk. The smell of roasting meat wafted into the hall, where slave girls carried round the jugs of mead. Iorweth the Druid bustled up and down the hall making a corridor between the men seated on the rush-strewn floor. He pushed men aside, bowed to the King when the corridor was made, then gestured with his staff for silence.

A great cheer erupted from the crowd outside.

The guests of honour had entered the hall from the rear, stepping straight from the night’s shadows onto the dais, but Ceinwyn would make her entrance through the large door at the front of the hall and to reach that door she had to walk through the throng of guests waiting in the tire-lit compound. The cheer we heard was the sound of those guests applauding her progress from the women’s hall, while inside the King’s hall we waited for her in expectant silence. Even the harpist lifted her ringers from the strings to watch the door.

A child entered first. It was a small girl dressed in white linen who walked backwards up the aisle made by Iorweth for Ceinwyn’s passage. The child strewed dried petals of spring flowers on the newly laid rushes. No one spoke. Every eye was fixed on the door except for mine, for I was watching the dais. Lancelot gazed at the door, a half smile on his face. Cuneglas kept cuffing tears from his eyes, so great was his happiness. Arthur, the maker of peace, beamed. Guinevere alone was not smiling. She just looked triumphant. She had once been scorned in this hall and now she was disposing of its daughter in marriage.

I watched Guinevere as, with my right hand, I took the bone from my pouch. The rib felt smooth in my grasp and Issa, standing behind me with my shield, must have wondered what significance that piece of kitchen waste carried in this moon-bright night of gold and fire.

I looked at the hall’s great door just as Ceinwyn appeared and, in the instant before the cheers began in the hall, there was a gasp of astonishment. Not all the gold in Britain, not all the Queens of old, could have outshone Ceinwyn that night. I did not even need to look at Guinevere to know that she had been utterly outwitted on this night of beauty.

This, I knew, was Ceinwyn’s fourth betrothal feast. She had come here once for Arthur, but he had broken that oath under the spell of Guinevere’s love, and afterwards Ceinwyn had been betrothed to a Prince from distant Rheged, but he had died of a fever before they could marry; then, not long ago, she had carried the betrothal halter to Gundleus of Siluria, but he had died screaming under Nimue’s cruel hands, and now, for the fourth time, Ceinwyn carried the halter to a man. Lancelot had given her a hoard of gold, but custom demanded that she return to him the gift of a common ox halter as a symbol that from this day on she would submit to his authority.

Lancelot stood as she entered and the half smile spread into a look of joy, and no wonder, for her beauty was dazzling. At her other betrothals, as befitted a Princess, Ceinwyn had come in jewels and silver, in gold and finery, but this night she wore only a simple bone-white gown that was belted with a pale blue cord that hung by the dress’s simple skirt to end in tassels. No silver decked her hair, no gold showed at her throat, she wore no precious jewels anywhere, just the linen dress and, about her pale blonde hair, a delicate blue wreath made from the last dog-violets of summer. She wore no shoes, but stepped barefoot among the petals. She displayed no sign of royalty or any symbol of wealth, but had just come to the hall dressed as simply as any peasant girl, and it was a triumph. No wonder men gasped, and no wonder they cheered as she paced slow and shy-between the guests. Cuneglas was weeping for happiness, Arthur led the applause, Lancelot smoothed his oiled hair and his mother beamed her approval. For a moment Guinevere’s face was unreadable, but then she smiled, and it was a smile of pure triumph. She might have been outshone by Ceinwyn’s beauty, but this night was still Guinevere’s night and she was seeing her old rival being consigned to a marriage of her own devising. I saw that smirk of triumph on Guinevere’s face and maybe it was her gloating satisfaction that made up my mind. Or maybe it was my hatred for Lancelot, or my love for Ceinwyn, or maybe Merlin was right and the Gods do love chaos for, in a sudden surge of anger, I gripped the bone in both my hands. I did not think of the consequences of Merlin’s magic, of his hatred for the Christians or the risk that we would all die pursuing the Cauldron in Diwrnach’s realm. I did not think of Arthur’s careful order, I was only aware that Ceinwyn was being given to a man I hated. I, like the other guests on the floor, was standing and watching Ceinwyn between the heads of the warriors. She had reached the great central oak pillar of the high hall where she was surrounded and besieged by the wolfish din of cheers and whistles. I alone was silent on the floor. I watched her and I placed my two thumbs at the centre of the rib and gripped its ends between my fists. Now, Merlin, I thought, now, you old rogue, let me see your magic now.

I snapped the rib. The noise of its splintering was lost among the cheers. I pushed the rib’s broken halves into the pouch, and I swear my heart was hardly beating as I watched the Princess of Powys who had stepped from the night with flowers in her hair. And who now suddenly stopped. Just beside the pillar hung with berries and leaves, she stopped. From the moment Ceinwyn had entered the hall she had kept her eyes on Lancelot and they were on him still and a smile was still on her face, but she stopped and her sudden stillness caused a slow puzzled silence to fall across the hall. The child scattering petals frowned and looked about for guidance. Ceinwyn did not move.

Arthur, smiling still, must have thought she had been overcome by nerves for he beckoned her encouragingly. The halter in her hands trembled. The harpist struck one uncertain chord, then lifted her fingers from the strings, and as her notes died away in the silence I saw a black-cloaked figure come from the crowd beyond the pillar.

It was Nimue, her one gold eye reflecting the flames in the puzzled hall. Ceinwyn looked from Lancelot to Nimue and then, very slowly, she held out a white-sleeved arm. Nimue took her hand and looked into the Princess’s eyes with a quizzical expression. Ceinwyn paused for a heartbeat, then gave the smallest nod of consent. Suddenly the hall was urgent with talk as Ceinwyn turned away from the dais and, following Nimue’s lead, plunged into the crowd. The talk died away for no one could find any explanation for what was now happening. Lancelot, left standing on the dais, could only watch. Arthur’s mouth had dropped open while Cuneglas, half risen from his seat, stared incredulously as his sister threaded the crowd that edged aside from Nimue’s fierce, scarred and derisive face. Guinevere looked ready to kill.

Then Nimue caught my eye and smiled and I felt my heart beating like a trapped wild thing. Then Ceinwyn smiled at me and I had no eyes for Nimue, only for Ceinwyn, sweet Ceinwyn, who was carrying the ox halter through the crowd of men towards my place in the hall. The warriors edged aside, but I seemed made of stone, unable to move or to speak as Ceinwyn, with tears in her eyes, came to where I stood. She said nothing, but just held the halter in offering to me. A babble of astonishment brewed all around us, but I ignored the voices. Instead I fell to my knees and took the halter, then I seized Ceinwyn’s hands and pressed them against my face that, like hers, was wet with tears. The hall was erupting in anger, in protest and amazement, but Issa stood over me with his shield raised. No man carried an edged weapon into a king’s hall, but Issa was holding the shield with its five-pointed star as though he would beat down any man who challenged the astonishing moment. Nimue, on my other side, was hissing curses into the hall, daring any man to challenge the Princess’s choice.

Ceinwyn knelt so that her face was close to mine. ‘You swore an oath. Lord,’ she whispered, ‘to protect me.’

‘I did, Lady.’

‘I release you from the oath if that is your wish.’

‘Never,’ I promised.

She pulled away slightly. ‘I will marry no man, Derfel,’ she warned me softly, her eyes on mine. ‘I will give you everything but marriage.’

‘Then you give me everything I could ever want, Lady,’ I said, my throat full and my eyes blurred with tears of happiness. I smiled and gave her back the halter. ‘Yours,’ I said. She smiled at that gesture, then dropped the halter into the straw and kissed me softly on the cheek. ‘I think,’ she whispered mischievously in my ear, ‘that this feast will go better without us.’ Then we both stood and, hand in hand, and ignoring the questions and protests and even some cheers, we walked into the moonlit night. Behind us was confusion and anger, and in front of us was a crowd of puzzled people through whom we walked side by side. ‘The house beneath Dolforwyn,’ Ceinwyn said, ‘is waiting for us.’

‘The house with the apple trees?’ I asked, remembering her telling me about the little house that she had dreamed of as a child.

‘That house,’ she said. We had left the crowd gathered about the hall doors and were walking towards Caer Sws’s torchlit gate. Issa had rejoined me after retrieving our swords and spears, and Nimue was at Ceinwyn’s other side. Three of Ceinwyn’s servants were hurrying to join us, as were a score of my men. ‘Are you certain of this?’ I asked Ceinwyn as though, somehow, she could turn back the last few minutes and restore the halter to Lancelot.

‘I am more certain,’ Ceinwyn said calmly, ‘than of anything I ever did before.’ She gave me an amused glance. ‘Did you ever doubt me, Derfel?’

‘I doubted myself,’ I said.

She squeezed my hand. ‘I am no man’s woman,’ she said, ‘only my own,’ and then she laughed with pure delight, let go of my hand and broke into a run. Violets fell from her hair as she ran for sheer joy across the grass. I ran after her, while behind us, from the astonished hall’s doorway, Arthur called for us to come back.

But we ran on. To chaos.

Next day I took a sharp knife and trimmed the snapped ends of the two bone fragments, and then, working very carefully, I made two long narrow troughs in Hywelbane’s wooden handgrips. Issa walked to Caer Sws and fetched back some glue that we heated over the fire and, once we were sure that the two troughs exactly matched the shape of the bone fragments, we coated the troughs with the glue, then pushed the two scraps into the sword’s hilt. We wiped off the excess glue, then bound the strips with bands of sinew to set them firmly into the wood. ‘It looks like ivory,’ Issa said admiringly when the job was done.

‘Strips of pig bone,’ I said dismissively, though in fact the two scraps did look like ivory and gave Hywelbane a rich appearance. The sword was named for its first owner, Merlin’s steward Hywel, who had taught me my weapons.

‘But the bones are magic?’ Issa asked me anxiously.

‘Merlin’s magic,’ I said, but I did not explain any further.

Cavan came to me at midday. He knelt on the grass and bowed his head, but he did not speak, nor did he need to speak for I knew why he had come. ‘You are free to go, Cavan,’ I told him. ‘I release you from your oath.’ He looked up at me, but the business of being freed of an oath was too heavy for him to say anything, so I smiled. ‘You’re not a young man, Cavan,’ I said, ‘and you deserve a lord who will offer you gold and comfort instead of a Dark Road and uncertainty.’

‘I have a mind. Lord,’ he found his voice at last, ‘to die in Ireland.’

‘To be with your people?’

‘Yes, Lord. But I cannot go back a poor man. I need gold.’

‘Then burn your throwboard,’ I advised him.

He grinned at that, then kissed Hywelbane’s hilt. ‘No resentment. Lord?’ he asked me anxiously.

‘No,’ I said, ‘and if you ever need my help, send word.’

He stood and embraced me. He would go back to Arthur’s service and take with him half my men, for only twenty stayed with me. The others feared Diwrnach, or else were too eager to find riches, and I could not blame them. They had earned honour, warrior rings and wolf-tails in my service, but little gold. I gave them permission to keep the wolf-tails on their helmets, for those they had earned in the terrible fights in Benoic, but I made them paint out the newly made stars on their shields. The stars were for the twenty men who stayed with me, and those twenty were the youngest, the strongest and the most adventurous of my spearmen and, the Gods know, they needed to be, for by snapping the bone I had committed them to the Dark Road.

I did not know when Merlin would summon us and so I waited in the small house to which Ceinwyn had led us in the moonlight. The house lay north and east of Dolforwyn in a small valley so steep that the shadows did not flee from the stream until the sun was halfway up its climb in the morning sky. The valley’s steep sides were shrouded by oaks, though around the house was a patchwork of tiny fields where a score of apple trees had been planted. The house had no name; nor even did the valley, it was simply called Cwm Isaf, the Lower Valley, and it was now our home.

My men built huts among the trees on the valley’s southern slope. I did not know how I was to provide for twenty men and their families, for Cwm Isaf’s little farm would have been hard pressed to feed a fieldmouse, let alone a warrior band, but Ceinwyn had gold and, as she promised me, her brother would not let us starve. The farm, she told me, had belonged to her father, one of the thousands of scattered tenancies that had supported Gorfyddyd’s wealth. The last tenant had been a cousin of Caer Sws’s candleman, but he had died before Lugg Vale and no other tenant had yet been chosen. The house itself was a poor thing, a little rectangle of stone with a roof thickly thatched with rye-straw and bracken that desperately needed repair. There were three chambers inside. One, the central room, had been for the farm’s few beasts, and that room we swept clean to give ourselves a living space. The other rooms were sleeping chambers, one for Ceinwyn and the other one for me.

‘I have promised Merlin,’ she had said that first night in explanation of the two sleeping chambers. I felt my flesh crawl. ‘Promised him what?’ I asked.

She must have blushed, but no moonlight came into deep Cwm Isaf and so I could not see her face, but only feel the pressure of her fingers in mine. ‘I have promised him,’ she said slowly, ‘that I will stay a virgin till the Cauldron is found.’

I had begun to understand then just how subtle Merlin had been. How subtle and wicked and clever. He needed a warrior to protect him while he travelled into Lleyn and he needed a virgin to find the Cauldron, and so he had manipulated us both. ‘No!’ I protested. ‘You can’t go into Lleyn!’

‘Only a virgin can discover the Cauldron,’ Nimue had hissed at us from the dark. ‘Would you have us take a child, Derfel?’

‘Ceinwyn cannot go to Lleyn,’ I insisted.

‘Quiet,’ Ceinwyn had hushed me. ‘I promised. I made an oath.’

‘Do you know what Lleyn is?’ I asked her. ‘You know what Diwrnach does?’

‘I know,’ she said, ‘that the journey there is the price I pay for being here with you. And I promised Merlin,’ she said again. ‘I made an oath.’

And so I slept alone that night, but in the morning, after we had shared a scanty breakfast with our spearmen and servants, and before I put the bone scraps into Hywelbane’s hilt, Ceinwyn walked with me up Cwm Isaf’s stream. She listened to my passionate arguments why she should not travel the Dark Road, and she dismissed them all by saying that if Merlin was with us then who could prevail against us?

‘Diwrnach could,’ I said grimly.

‘But you’re going with Merlin?’ she asked me.

‘Yes.’

‘Then don’t prevent me,’ she insisted. ‘I will be with you, and you with me.’ And she would hear no more argument. She was no man’s woman. She had made up her mind.

And then, of course, we spoke of what had happened in the last few days and our words tumbled out. We were in love, smitten just as hard as Arthur had been smitten by Guinevere, and we could not hear enough of the other’s thoughts and stories. I showed her the pork bone and she laughed when I told her how I had waited till the last moment to snap it in two.

‘I really didn’t know if I dared turn away from Lancelot,’ Ceinwyn admitted. ‘I didn’t know about the bone, of course. I thought it was Guinevere who made up my mind.’

‘Guinevere?’ I asked, surprised.

‘I couldn’t bear her gloating. Is that awful of me? I felt as though I was her kitten, and I couldn’t bear it.’ She walked on in silence for a while. Leaves drifted down from the trees that were still mostly green. That morning, waking to my first dawn in Cwm Isaf, I had seen a martin fly away from the thatch. He did not come back and I guessed we would not see another till the spring. Ceinwyn walked barefoot beside the stream, her hand in mine. ‘And I’ve been wondering about that prophecy of the skull bed,’ she went on, ‘and I think it means I’m not supposed to marry. I’ve been betrothed three times, Derfel, three times!

And three times I lost the man, and if that isn’t a message from the Gods, what is?’

‘I hear Nimue,’ I said.

She laughed. ‘I like her.’

‘I couldn’t imagine the two of you liking each other,’ I confessed.

‘Why ever not? I like her belligerence. Life is for the taking, not for submission, and all my life, Derfel, I’ve done what people told me to do. I’ve always been good,’ she said, giving the word ‘good’ a wry stress. ‘I was always the obedient little girl, the dutiful daughter. It was easy, of course, for my father loved me and he loved so few people, but I was given everything I ever wanted and in return all they ever wanted of me was that I should be pretty and obedient. And I was very obedient.’

‘Pretty, too.’

She dug an elbow into my ribs as reproof. A flock of pied wagtails flew up from the mist that shrouded the stream ahead of us. ‘I was always obedient,’ Ceinwyn said wistfully. ‘I knew I would have to marry where I was told to marry, and that didn’t worry me because that’s what kings’ daughters do, and I can remember being so happy when I first met Arthur. I thought that my whole lucky life would go on for ever. I had been given such a good man, and then, suddenly, he vanished.’

‘And you didn’t even notice me,’ I said. I had been the youngest spearman in Arthur’s guard when he came to Caer Sws to be betrothed to Ceinwyn. It was then that she had given me the small brooch I still wore. She had rewarded all Arthur’s escort, but never knew what a fire she started in my soul that day.

‘I’m sure I did notice you,’ she said. ‘Who could miss such a big, awkward, straw-haired lump?’ She laughed at me, then let me help her over a fallen oak. She wore the same linen dress she had worn the previous night, though now the bleached skirt was soiled with mud and moss. ‘Then I was betrothed to Caelgyn of Rheged,’ she continued her tale, ‘and I wasn’t quite so sure I was lucky any more. He was a sullen beast, but he promised to bring father a hundred spearmen and a bride-price of gold and I convinced myself I would be happy all the same, even if I did have to live in Rheged, but Caelgyn died of the fever. Then there was Gundleus.’ She frowned at that memory. ‘I realized then that I was just a throwpiece in a game of war. My father loved me, but he would even let me go to Gundleus if that meant more spears to carry against Arthur. That was when I first understood that I would never be happy unless I made my own happiness, and it was just then that you and Galahad came to see us. Remember?’

‘I remember.’ I had accompanied Galahad on his failed mission of peace and Gorfyddyd, as an insult, had made us dine in the women’s hall. There in the candlelight, as a harpist played, I had talked to Ceinwyn and given her my oath to protect her.

‘And you cared whether I was happy,’ she said.

‘I was in love with you,’ I confessed. ‘I was a dog howling at a star.’

She smiled. ‘And then came Lancelot. Lovely Lancelot. Handsome Lancelot, and everyone told me I was the luckiest woman in Britain, but do you know what I sensed? That I would just be another possession to Lancelot, and he seems to have so many already. But I still wasn’t sure what I should do, then Merlin came and talked to me, and he left Nimue and she talked and talked, but I already knew I didn’t want to belong to any man. I’ve belonged to men all my life. So Nimue and I made an oath to Don and I swore to Her that if She gave me the strength to take my own freedom then I would never marry. I will love you,’ she promised me, looking up into my face, ‘but I will not be any man’s possession.’

Maybe not, I thought, but she, like me, was still Merlin’s gaming piece. How busy he had been, he and Nimue, but I said nothing of that, nor of the Dark Road. ‘But you will be Guinevere’s enemy now,’ I warned Ceinwyn instead.

‘Yes,’ she said, ‘but I always was, right from the moment when she decided to take Arthur away from me, but I was just a child then and I didn’t know how to tight her. Last night I struck back, but from now on I’ll just stay out of sight.’ She smiled. ‘And you were to marry Gwenhwyvach?’

‘Yes,’ I confessed.

‘Poor Gwenhwyvach,’ Ceinwyn said. ‘She was always very good to me when they lived here, but I remember every time her sister came into the room she’d run away. She was like a big plump mouse and her sister was the cat.’

Arthur came to the lower valley that afternoon. The glue holding the scraps of bone were still drying in Hywelbane’s hilt as his warriors filled the trees on Cwm Isaf’s southern slope that faced our small house. The spearmen did not come to threaten us, but had merely diverted themselves from their long march home to comfortable Dumnonia. There was no sign of Lancelot, nor of Guinevere, as Arthur walked alone across the stream. He carried no sword or shield.

We met him at our door. He bowed to Ceinwyn, then smiled at her. ‘Dear Lady,’ he said simply.

‘You are angry with me, Lord?’ she asked him anxiously.

He grimaced. ‘My wife believes I am, but no. How can I be angry? You only did what I once did, and you had the grace to do it before the oath was given.’ He smiled at her again. ‘You have, perhaps, inconvenienced me, but I deserved that. May I walk with Derfel?’

We followed the same path that I had taken that morning with Ceinwyn, and Arthur, once he was out of sight of his spearmen, put an arm about my shoulders. ‘Well done, Derfel,’ he said quietly.

‘I am sorry if it hurt you, Lord.’

‘Don’t be a fool. You did what I once did and I envy you the newness of it. It just changes things, that’s all. It is, as I said, inconvenient.’

‘I won’t be Mordred’s champion,’ I said.

‘No. But someone will. If it was up to me, my friend, I would take you both home and make you champion and give you all I had to give, but things cannot always be as we want.’

‘You mean,’ I said bluntly, ‘that the Princess Guinevere will not forgive me.’

‘No,’ Arthur said bleakly. ‘Nor will Lancelot.’ He sighed. ‘What shall I do with Lancelot?’

‘Marry him to Gwenhwyvach,’ I said, ‘and bury them both in Siluria.’

He laughed. ‘If only I could. I’ll send him to Siluria, certainly, but I doubt Siluria will hold him. He has ambitions above that small kingdom, Derfel. I’d hoped that Ceinwyn and a family would keep him there, but now?’ He shrugged. ‘I would have done better to give the kingdom to you.’ He took his arm from about my shoulders and faced me. ‘I do not release you from your oaths, Lord Derfel Cadarn,’ he said formally, ‘you are still my man and when I send for you, you will come to me.’

‘Yes, Lord.’

‘That will be in the spring,’ he said. ‘I am sworn to three months’ peace with the Saxons and I will keep that peace, and when the three months are up the winter will keep our spears stacked. But in the spring we march and I shall want your men in my shield-wall.’

‘They will be there, Lord,’ I promised him.

He raised both hands and put them on my shoulders. ‘Are you also sworn to Merlin?’ he asked, staring into my eyes.

‘Yes, Lord,’ I admitted.

‘So you’ll chase a Cauldron that doesn’t exist?’

‘I shall seek the Cauldron, yes.’

He closed his eyes. ‘Such stupidity!’ He dropped his hands and opened his eyes. ‘I believe in the Gods, Derfel, but do the Gods believe in Britain? This isn’t the old Britain,’ he said vehemently. ‘Maybe once we were a people of one blood, but now? The Romans brought men from every corner of the world! Sarmatians, Libyans, Gauls, Numidians, Greeks! Their blood is mingled with ours, just as it seethes with Roman blood and mixes now with Saxon blood. We are what we are, Derfel, not what we once were. We have a hundred Gods now, not just the old Gods, and we cannot turn the years back, not even with the Cauldron and every Treasure of Britain.’

‘Merlin disagrees.’

‘And Merlin would have me fight the Christians just so his Gods can rule? No, I won’t do it, Derfel.’

He spoke angrily. ‘You can look for your imaginary Cauldron, but don’t think I’ll play Merlin’s game by persecuting Christians.’

‘Merlin,’ I said defensively, ‘will leave the fate of the Christians to the Gods.’

‘And what are we but the Gods’ implements?’ Arthur asked. ‘But I won’t fight other Britons just because they worship another God. Nor will you, Derfel, so long as you’re oath-sworn.’

‘No, Lord.’

He sighed. ‘I do hate all this rancour about Gods. But then, Guinevere always tells me I am blind to the Gods. She says it’s my one fault.’ He smiled. ‘If you’re sworn to Merlin, Derfel, then you must go with him. Where will he take you?’

‘To Ynys Mon, Lord.’

He stared at me in silence for a few heartbeats, then shuddered.

‘You go to Lleyn?’ he asked incredulously. ‘No one comes alive from Lleyn.’

‘I shall,’ I boasted.

‘Make sure you do, Derfel, make sure you do.’ He sounded gloomy. ‘I need you to help me beat the Saxons. And after that, maybe, you can return to Dumnonia. Guinevere isn’t a woman to hold grudges.’ I doubted that, but said nothing. ‘So I shall summon you in the spring,’ Arthur went on, ‘and pray you survive Lleyn.’ He put an arm through mine and walked me back towards the house. ‘And if anyone asks you, Derfel, then I have just reproved you angrily. I have cursed you, even struck you.’

I laughed. ‘I forgive you the blow, Lord.’

‘Consider yourself reproved,’ he said, ‘and consider yourself,’ he went on, ‘the second luckiest man in Britain.’

The luckiest in the world, I thought, for I had my soul’s desire.

Or I would have it, the Gods preserve us, when Merlin had his.

I stood and watched the spearmen go. Arthur’s banner of the bear showed briefly in the trees, he waved, hoisted himself onto his horse’s back and then was gone.

And we were alone.

So I was not in Dumnonia to see Arthur’s return. I should have liked that, for he rode back a hero to a country that had dismissed his chances of survival and had plotted to replace him by lesser creatures. Food was scarce that autumn, for the sudden flare of war had depleted the new harvest, but there was no famine and Arthur’s men collected fair taxes. That sounds like a small improvement, but after the recent years it caused a stir in the land. Only the rich paid taxes to the Royal Treasury. Some paid in gold, but most paid in grain and leather and linen and salt and wool and dried fish that they, in turn, had demanded from their tenants. In the last few years the rich had paid little to the King and the poor had paid much to the rich, so Arthur sent spearmen to inquire of the poor what tax had been levied of them and used their answers to make his own levy of the rich. From the proceeds he returned a third of the yield back to the churches and magistrates so that they could distribute the food in the winter. That action alone told Dumnonia that a new power had come to the land, and though the wealthy grumbled, none dared raise a shield-wall to tight Arthur. He was the warlord of Mordred’s kingdom, the victor of Lugg Vale, the slaughterer of Kings, and those who opposed him now feared him. Mordred was moved into the care of Culhwch, Arthur’s cousin and a crude, honest warrior who probably took small interest in the fate of a small and troublesome child. Culhwch was too busy suppressing the revolt that had been started by Cadwy of Isca deep in Dumnonia’s west, and I heard that he led his spears in a swift campaign across the great moor, then south into the wild land on the coast. He ravaged Cadwy’s heartland, then stormed the rebellious Prince in the old Roman stronghold of Isca. The walls had decayed and the veterans of Lugg Vale swarmed over the town’s ramparts to hunt the rebels through the streets. Prince Cadwy was caught in a Roman shrine and there dismembered. Arthur ordered parts of his body to be displayed in Dumnonia’s towns, and his head, with its easily recognizable blue tattoos on the cheeks, to be sent to King Mark of Kernow who had encouraged the revolt. King Mark sent back a tribute of tin ingots, a tub of smoked fish, three polished turtle shells that had washed up on the shores of his wild country and an innocent disavowal of any complicity in Cadwy’s rebellion. Culhwch, in capturing Cadwy’s stronghold, found letters there that he sent to Arthur. The letters were from the Christian party in Dumnonia and had been written before the campaign that ended in Lugg Vale, and they revealed the full extent of the plans to rid Dumnonia of Arthur. The Christians had disliked Arthur ever since he had revoked High King Uther’s rule that the church was to be exempt from taxes and loans, and they had become convinced that their God was leading Arthur to a great defeat at Gorfyddyd’s hands. It was the prospect of that almost certain defeat that had encouraged them to put their thoughts into writing, and those same writings were now in Arthur’s keeping. The letters revealed a worried Christian community who wanted Arthur’s death, but also feared the incursion of Gorfyddyd’s pagan spearmen. To save themselves and their riches they had been ready to sacrifice Mordred, and the letters encouraged Cadwy to march on Durnovaria during Arthur’s absence, kill.Mordred and then yield the kingdom to Gorfyddyd. The Christians promised him help, and hoped that Cadwy’s spears would protect them once Gorfyddyd ruled.

Instead it brought them punishment. King Melwas of the Iklgae, a client King who had sided with the Christians who opposed Arthur, was made the new ruler of Cadwy’s land. It was hardly a reward, for it took Melwas far away from his own people to a place where Arthur could keep him under close watch. Nabur, the Christian magistrate who had held Mordred’s guardianship, and who had used that guardianship to raise the party that opposed Arthur and who was the writer of the letters suggesting Mordred’s murder, was nailed to a cross in Durnovaria’s amphitheatre. These days, of course, he is called a saint and martyr, but I only remember Nabur as a smooth, corrupt liar. Two priests, another magistrate and two landowners were also put to death. The last conspirator was Bishop Sansum, though he had been too clever to let his name be put into writing, and that cleverness, together with his strange friendship for Arthur’s maimed pagan sister, Morgan, saved Sansum’s life. He swore undying loyalty to Arthur, put a hand on a crucifix and swore he had never plotted to kill the King, and so remained as the guardian of the shrine of the Holy Thorn at Ynys Wydryn. You could bind Sansum in iron and hold a sword to his throat, and still he would slither free.

Morgan, his pagan friend, had been Merlin’s most trusted priestess until the younger Nimue usurped that position, but Merlin and Nimue were both far away and that left Morgan as virtual ruler of Merlin’s lands in Avalon. Morgan, with her gold mask hiding her fire-ravaged face and her black robe shrouding her flame-twisted body, assumed Merlin’s power and it was she who finished the rebuilding of Merlin’s hall on the Tor, and she who organized the tax-collectors in the northern part of Arthur’s land. Morgan became one of Arthur’s most trusted advisers; indeed, after Bishop Bedwin died of a fever that autumn, Arthur even suggested, against all precedence, that Morgan be named as a full councillor. No woman had ever sat on a King’s Council in Britain and Morgan might well have been the first, but Guinevere made sure she was not. Guinevere would let no woman be a councillor if she could not be one herself, and besides, Guinevere hated anything that was ugly and, the Gods know, poor Morgan was grotesque even with her gold mask in place. So Morgan stayed in Ynys Wydryn, while Guinevere supervised the building of the new palace at Lindinis.

It was a gorgeous palace. The old Roman villa that Gundlcus had burned was rebuilt and extended so that its cloistered wings enclosed two great courtyards where water flowed in marble channels. Lindinis, close to the royal hill of Caer Cadarn, was to be Dumnonia’s new capital, though Guinevere took good care that Mordred, with his twisted left foot, was allowed nowhere near the place. Only the beautiful were allowed in Lindinis, and in its arcaded courtyards Guinevere assembled statues from villas and shrines throughout Dumnonia. There was no Christian shrine there, but Guinevere made a great dark hall for the women’s Goddess Isis, and she provided a lavish suite of rooms where Lancelot could stay when he visited from his new kingdom in Siluria. Elaine, Lancelot’s mother, lived in those rooms and she, who had once made Ynys Trebes so beautiful, now helped Guinevere make Lindinis’s palace into a shrine of beauty.

Arthur, I know, was rarely at Lindinis. He was too busy preparing for the great war against the Saxons, to which end he began re-fortifying the ancient earth citadels in southern Dumnonia. Even Caer Cadarn, deep in our heartland, had its wall strengthened and new timber fighting platforms poised on its ramparts, but his greatest work was at Caer Ambra, just a half hour’s walk east of the Stones, which was to be his new base against the Sais. The old people had made a fort there, but all that autumn and winter the slaves toiled to steepen the ancient earth walls and to make new palisades and fighting platforms on their summits. More forts were strengthened south of Caer Ambra to defend the lower parts of Dumnonia against the southern Saxons led by Cerdic, who were sure to attack us while Arthur assaulted Aelle in the north. Not since the Romans, I dare say, had so much British earth been dug or timber split, and Arthur’s honest taxes could never pay for half that labour. He therefore made a levy on the Christian churches that were plentiful and powerful in southern Britain, the same churches that had supported Nabur and Sansum’s effort to topple him. That levy was eventually repaid, and it protected the Christians from the ghastly attentions of the Saxon heathens, but the Christians never forgave Arthur, nor did they notice that the same levy was taken from the handful of pagan shrines that still possessed wealth.

Not all the Christians were Arthur’s enemies. At least a third of his spearmen were Christians and those men were as loyal as any pagan. Many other Christians approved of his rule, but most of the leaders of the church let their greed dictate their loyalty and they were the ones who opposed him. They believed that their God would one day return to this earth and walk among us like a mortal man, but He would not come again until all pagans had been converted to His faith. The preachers, knowing that Arthur was a pagan, hissed curses at him, but Arthur ignored their words as he made his ceaseless tours of southern Britain. One day he would be with Sagramor on Aelle’s border, the next he would be fighting one of Cerdic’s war-bands as it probed deep into the river valleys of the south, and then he would ride north through Dumnonia and across Gwent to Isca where he would argue with local chieftains about the number of spearmen who could be raised from western Gwent or eastern Siluria. Thanks to Lugg Vale Arthur was now far more than Dumnonia’s chief lord and Mordred’s protector; he was Britain’s warlord, the undisputed leader of all our armies, and no King dared refuse him, nor, in those days, wanted to.

But all this I missed, for I was in Caer Sws and I was with Ceinwyn and I was in love. And waiting for Merlin.

Merlin and Nimue came to Cwm Isaf just days before the winter solstice. Dark clouds were pressing close above the bare oak tops on the ridges, and the morning frost had lingered well into the afternoon. The stream was a patchwork of ice ledges and trickling water, the fallen leaves were crisp and the valley’s soil as hard as stone. We had a fire in the central chamber so our house was warm enough, though it was choking with the smoke that billowed about the un-trimmed beams before finding the small hole in the roof’s ridge. Other fires smoked from the shelters that my spearmen had made across the valley; stout little huts with walls of earth and stone supporting roofs of timber and bracken. We had made a beast shed behind the house where a bull, two cows, three sows, a boar, a dozen sheep and a score of chickens were penned at night to protect them from the wolves. We had plenty of wolves in our woods and their howling echoed at every dusk, and at night we would sometimes hear them scrabbling beyond the beast shed. The sheep would bleat piteously, the hens would set up a cackling panic, and then Issa, or whoever else stood guard, would shout and hurl a firebrand into the wood’s edge and the wolves would skitter away. One morning, going early to fetch water from the stream, I came face to face with a big old dog wolf. He had been drinking, but as I stepped out of the bushes he raised a grey muzzle, stared at me, then waited for my salute before he loped silently upstream. It was, I decided, a good omen and, in those days as we waited for Merlin, we counted the omens. We also hunted the wolves. Cuneglas gave us three brace of longhaired wolfhounds that were bigger and shaggier than the famous Powysian deerhounds like those Guinevere kept in Dumnonia. The sport kept my spearmen active and even Ceinwyn liked those long cold days in the high woods. She wore leather breeches, high boots and a leather jerkin, and hung a hunter’s long knife at her waist. She would braid her fair hair into a knot at the back of her head, then scramble up rocks and down gullies and over dead trees behind her brace of hounds who were leashed on long horsehair ropes. The simplest way to hunt wolves was with a bow and arrow, but as few of us possessed that skill we used the dogs, war spears and knives, and by the time Merlin returned we had a pile of pelts stacked in Cuneglas’s store hall. The King had wanted us to move back to Caer Sws, but Ceinwyn and I were as happy as our anticipation of Merlin’s ordeal allowed us and so we stayed in our small valley and counted the days. And we were happy in Cwm Isaf. Ceinwyn took a ridiculous pleasure in doing all the things that till now had been done for her by servants, though strangely she was never able to wring a chicken’s neck and I always used to laugh when she killed a hen. She had no need to do it, for any one of the servants could have killed the fowl and my spearmen would do anything for Ceinwyn, but she insisted on sharing the work, though when it came to killing hens, ducks or geese she could not make herself do it properly. The only method she ever devised was to lay the poor creature down on the earth, put a small foot on its neck and then, with her eyes tight closed, give the head one quick decisive tug. She was more successful with the distaff. Every woman in Britain, save for the very richest, was forever with a distaff and spindle, for spinning wool into thread was one of those endless jobs that will presumably last until the sun has made its last turn about the earth. As soon as one year’s fleeces had been turned into yarn, so the next year’s fleeces came to the storehouses and the women would collect their apronfuls, wash and comb the wool, then start spinning the thread again. They spun when they walked, they spun as they talked, they spun whenever there was no other task needing their hands. It was monotonous, mindless work, but not unskilled; at first Ceinwyn could only produce pathetic little tatters of wool, but she became better, though never as quick as those women who had spun the wool since the very first day their hands were big enough to hold the distaff. She would sit of an evening, telling me about her day, and her left hand would turn the staff and her right would flick the weighted spindle that hung from the distaff to elongate and twist the emerging thread. When the spindle reached the floor she would wind the thread around it, fix the spooled yarn with the bone clip on the spindle’s top and then start spinning again. The wool she made that winter was often lumpy, or else fragile, but I loyally wore one of the shirts she made from that thread until it fell apart.

Cuneglas visited us often, though his wife, Helledd, never came. Queen Helledd was truly conventional and she disapproved deeply of what Ceinwyn had done. ‘She thinks it brings disgrace on the family,’

Cuneglas told us cheerfully. He became, like Arthur and Galahad, one of my dearest friends. He was, I think, lonely in Caer Sws, for other than Iorweth and some of the younger Druids he had few men with whom he could talk of anything but hunting and war, and so I replaced the brothers he had lost. His older brother, who should have become King, had been killed in a fall from a horse, the next son had died of a fever and the youngest had been killed fighting the Saxons. Cuneglas, like me, deeply disapproved of Ceinwyn’s going on the Dark Road, but he told me that nothing short of a sword blow would ever stop her. ‘Everyone always thinks she’s so sweet and kind,’ he told me, ‘but there’s a will of iron there. Stubborn.’

‘Can’t kill chickens.’

‘I can’t even imagine her trying!’ he laughed. ‘But she is happy, Derfel, and for that I thank you.’

It was a happy time, one of the happiest of all our happy times, but always shadowed by the knowledge that Merlin would come and demand the fulfilment of our oaths. He came on a frosty afternoon. I was outside the house, using a Saxon war axe to split newly chopped logs that would fill our house with smoke, and Ceinwyn was inside, hushing a squabble that had risen between her maidservants and the fiery Scarach, when a horn sounded across the valley. The horn was a signal from my spearmen that a stranger approached Cwm Isaf and I lowered the axe in time to see Merlin’s tall figure striding among the trees. Nimue was with him. She had stayed a week with us after the night of Lancelot’s betrothal and then, without a word of explanation, had slipped away one night, but now, dressed in black beside her lord in his long white robe, she returned. Ceinwyn came from the house. Her face was smudged with soot and her hands bloodied from a hare she had been jointing. ‘I thought he was bringing a war-band,’ she said, her blue eyes fixed on Merlin. That was what Nimue had told us before she left; that Merlin was raising the army that would protect him on the Dark Road.

‘Maybe he’s left them at the river?’ I suggested.

She pushed a lock of hair away from her face, adding a smudge of blood to the soot. ‘Aren’t you cold?’ she asked, for I had been stripped to the waist as I chopped the wood.

‘Not yet,’ I said, though I pulled on a wool shirt as Merlin leapt long legged over the stream. My spearmen, anticipating news, trailed from their huts to follow him, but they stayed outside the house when he ducked his tall figure under our low lintel.

He offered us no greeting, but just went past us into the house. Nimue followed him, and by the time Ceinwyn and I entered they were already squatting beside the fire. Merlin held his thin hands to the blaze, then seemed to give a long sigh. He said nothing, and neither of us wanted to ask his news. I, like him, sat at the fire’s edge while Ceinwyn put the half jointed hare into a bowl then wiped her hands free of blood. She waved Scarach and the servants out of the house, then sat beside me. Merlin shivered, then seemed to relax. His long back was bowed as he hunched forward with his eyes closed. He stayed thus for a long time. His brown face was deeply lined and his beard a startling white. Like all Druids he shaved the front part of his skull, but now that tonsure was smothered with a fine layer of short white hair, evidence that he had been a long time on the road without a razor or a bronze mirror. He looked so old that day, and hunched by the fire he even looked feeble. Nimue sat opposite him, saying nothing. She did rise once to take Hywelbane from its nail hooks in the main beam and I saw her smile as she recognized the two strips of bone set into the handle. She unsheathed the blade, then held it into the smokiest part of the fire, and once the steel was covered in soot she carefully scratched an inscription into the soot with a piece of straw. The letters were not like these I write now, that both we and the Saxons employ, but were older magical letters, mere strokes slashed by bars, that only the Druids and sorcerers used. She propped the scabbard against the wall and hung the sword back on its nails, but did not explain the significance of what she had written. Merlin ignored her.

He opened his eyes suddenly, and the appearance of feebleness was replaced by a terrible savagery.

‘I put a curse,’ he said slowly, ‘on the creatures of Siluria.’ He flicked his fingers towards the fire and a puff of brighter flame hissed in the wood. ‘May their crops be blighted,’ he growled, ‘their cattle barren, their children crippled, their swords blunted and their enemies triumphant.’ It was, for him, a mild enough curse, but there was a hissing malevolence in his voice. ‘And on Gwent,’ he went on, ‘I give a murrain, and frosts in summer and wombs shrivelled to dry husks.’ He spat into the flames. ‘In Elmet,’ he said,

‘the tears will make lakes, plagues will fill graves, and rats shall rule their houses.’ He spat again. ‘How many men will you bring, Derfel?’

‘All I have, Lord.’ I hesitated to admit how few that was, but I finally gave him the answer, ‘Twenty shields.’

‘And those of your men who are still with Galahad?’ He gave me a quick glance from beneath his bushy white eyebrows. ‘How many of those?’

‘I have heard nothing from them, Lord.’

He sneered. ‘They form a palace guard for Lancelot. He insists on it. He makes his brother into a doorkeeper.’ Galahad was Lancelot’s half-brother and as unlike him as any man could be. ‘It is a good thing, Lady,’ Merlin looked at Ceinwyn, ‘that you did not marry Lancelot.’

She smiled at me. ‘I think so, Lord.’

‘He finds Siluria tedious. I can’t blame him for that, but he’ll seek Dumnonia’s comforts and be a snake in Arthur’s belly.’ He smiled. ‘You, my Lady, were supposed to be his plaything.’

‘I had rather be here,’ Ceinwyn said, gesturing at our rough stone walls and smoke-stained roof beams.

‘But he’ll try to strike at you,’ Merlin warned her. ‘His pride climbs higher than Lleullaw’s eagle, Lady, and Guinevere is cursing you. She killed a dog in her temple of Isis and draped its pelt on a crippled bitch that she gave your name.’

Ceinwyn looked pale, made the sign against evil and spat into the fire. Merlin shrugged. ‘I have countered the curse. Lady,’ he said, then stretched his long arms and bent his head back so that his ribboned plaits almost touched the rush-covered floor behind him. ‘Isis is a foreign Goddess,’ he said, ‘and her power is feeble in this land.’ He brought his head forward again, then rubbed his eyes with his long hands, I have come empty-handed,’ he said bleakly. ‘No man in Elmet would step forward, and none elsewhere. Their spears, they say, are dedicated to Saxon bellies. I offered them no gold, I offered no silver, only a fight on behalf of the Gods, and they offered me their prayers, then let their womenfolk talk to them of children and hearths and cattle and land and so they slunk away. Eighty men! That’s all I wanted. Diwrnach can field two hundred, maybe a handful more, but eighty would have sufficed, yet there were not even eight men who would come. Their Lords are sworn to Arthur now. The Cauldron, they tell me, can wait till Lloegyr is ours again. They want Saxon land and Saxon gold and all I offered them was blood and cold on the Dark Road.’

There was a silence. A log collapsed in the fire to spring a constellation of sparks toward the blackened roof. ‘Not one man offered a spear?’ I asked, shocked at the news.

‘A few,’ he said dismissively, ‘but none I would trust. None worthy of the Cauldron.’ He paused, then looked tired again. ‘I am struggling against the lure of Saxon gold and against Morgan. She opposes me.’

‘Morgan!’ I could not hide my astonishment. Morgan, Arthur’s eldest sister, had been Merlin’s closest companion until Nimue usurped her place, and though Morgan hated Nimue I did not think that hatred extended to Merlin.

‘Morgan,’ he said flatly. ‘She has spread a tale through Britain. The tale says that the Gods oppose my quest and that I am to be defeated, and that my death will embrace all my companions. She dreamed the tale and folk believe her dreams. I am old, she says, and feeble, and loose-witted.’

‘She says,’ Nimue spoke softly, ‘that a woman will kill you, not Diwrnach.’

Merlin shrugged. ‘Morgan plays her own game and I don’t yet understand it.’ He rooted about in a pocket of his gown and brought out a handful of dried knotted grasses. Each knotted stem looked alike to me, but he sorted through them and selected one that he held towards Ceinwyn. ‘I release you from your oath, Lady.’

Ceinwyn glanced at me, then looked back to the knot of grass. ‘Will you still take the Dark Road, Lord?’ she asked Merlin.

‘Yes.’

‘But how will you find the Cauldron without me?’

He shrugged, but offered no answer.

‘How will you find it with her?’ I asked, for I still did not understand why a virgin must find the Cauldron, or why that virgin should have to be Ceinwyn.

Merlin shrugged again. ‘The Cauldron,’ he said, ‘was ever under the guard of a virgin. One guards it now, if my dreams tell me correctly, and only another virgin can reveal its hiding-place. You will dream it,’ he said to Ceinwyn, ‘if you are willing to come.’

‘I shall come, Lord,’ Ceinwyn said, ‘as I promised you.’

Merlin pushed the grass knot back into the pocket before rubbing his face again with his long hands.

‘We leave in two days,’ he announced flatly. ‘You must bake bread, pack dried meat and fish, sharpen your weapons, and make sure you have furs against the cold.’ He looked at Nimue. ‘We shall sleep at Caer Sws. Come.’

‘You can stay here,’ I offered.

‘I must speak to Iorweth.’ He stood, his head level with the rafters. ‘I release you both from your oaths,’ he said very formally, ‘but pray you will come anyway. But it will be harder than you know and harder than you fear in your worst dreams, for I have pledged my life on the Cauldron.’ He looked down at us and his face was immensely sad. ‘The day we step on the Dark Road,’ he told us, ‘I shall begin to die, for that is my oath, and I have no certainty that the oath will bring me success, and if the search fails then I shall be dead and you will be alone in Lleyn.’

‘We shall have Nimue,’ Ceinwyn said.

‘And she is all you will have,’ Merlin said darkly, then ducked out of the door. Nimue followed him. We sat in silence. I put another log on the fire. It was green, for all our firewood was fresh-cut unseasoned timber which was why it smoked so badly. I watched the smoke thicken and swirl about the rafters, then took Ceinwyn’s hand. ‘Do you want to die in Lleyn?’ I chided her.

‘No,’ she said, ‘but I want to see the Cauldron.’

I stared into the fire. ‘He will fill it with blood,’ I said softly. Ceinwyn’s fingers caressed mine. ‘When I was a child,’ she said, ‘I heard all the tales of old Britain, how the Gods lived among us and everyone was happy. There was no famine then, and no plagues, just us and the Gods and peace. I want that Britain back, Derfel.’

‘Arthur says it can never return. We are what we are, not what we once were.’

‘So who do you believe?’ she asked. ‘Arthur or Merlin?’

I thought a long time. ‘Merlin,’ I finally said, and perhaps that was because I wanted to believe in his Britain where all our sorrows would be magically taken away. I loved the idea of Arthur’s Britain too, but that would take war and hard work and a trust that men would behave well if they were treated well. Merlin’s dream demanded less and promised more.

‘They we’ll go with Merlin,’ Ceinwyn said. She hesitated, watching me. ‘Are you worried by Morgan’s prophecy?’ she asked.

I shook my head. ‘She has power,’ I said, ‘but not like his. And not like Nimue, either.’ Nimue and Merlin had both suffered the Three Wounds of Wisdom, and Morgan had only endured the wound to the body, never the wound to the mind or the wound to pride; but Morgan’s prophecy was a shrewd tale, for in some ways Merlin was defying the Gods. He wanted to tame their caprices and in return give them a whole land dedicated to their worship, but why would the Gods want to be tamed? Maybe they had chosen Morgan’s lesser power to be their instrument against Merlin’s meddling, for what else could explain Morgan’s hostility? Or maybe Morgan, like Arthur, believed that Merlin’s quest was a nonsense, an old man’s hopeless search for a Britain that had vanished with the coming of the Legions. For Arthur there was only one fight, and that was to hurl the Saxon Kings from Britain, and Arthur would have supported his sister’s whispering tale if that meant no British spears were to be wasted against Diwrnach’s blood-painted shields. So perhaps Arthur was using his sister to make certain that no precious Dumnonian lives were to be thrown away in Lleyn. Except for my life, and my men’s lives, and my beloved Ceinwyn’s life. For we were oath-sworn.

But Merlin had released us from our oaths and so I tried one last time to persuade Ceinwyn to stay in Powys. I told her how Arthur believed that the Cauldron no longer existed, how it must have been stolen by the Romans and taken to that great sink of treasure, Rome, and melted down to make hair-combs or cloak-pins or coins or brooches. All that I told her, and when I was done she smiled and asked me once again who I believed, Merlin or Arthur.

‘Merlin,’ I said again.

‘And so do I,’ Ceinwyn said. ‘And I’m going.’

We baked bread, packed food and sharpened our weapons. And the next night, the eve of our going on Merlin’s quest, the first snow fell.

Cuneglas gave us two ponies that we loaded with food and furs, then we slung our star-painted shields on our backs and took the northern road. Iorweth gave us a blessing and Cuneglas’s spearmen accompanied us for the first few miles, but once we had passed the great ice wastes of the Dugh bog that lay beyond the hills north of Caer Sws those spearmen stepped aside and we were alone. I had promised Cuneglas that I would protect his sister’s life with my own and he had embraced me, then whispered in my ear. ‘Kill her, Derfel,’ he said, ‘rather than let Diwrnach have her.’

There were tears in his eyes and they almost made me change my mind. ‘If you order her not to go, Lord King,’ I said, ‘she might obey.’

‘Never,’ he said, ‘but she is happier now than she has ever been. Besides, Iorweth tells me you will return. Go, my friend.’ He had stepped back. His parting gift had been a bag of gold ingots that we stowed on one of the ponies.

The snowy road led north into Gwynedd. I had never been to that kingdom before and found it a crude, hard place. The Romans had come here, but only to dig lead and gold. They had left few marks on the land and given it no law. The folk lived in squat, dark huts that huddled together inside circling stone walls from which dogs snarled at us and on which the skulls of wolves and bears were mounted to deter the spirits. Cairns marked the summits of hills and every few miles we would find a pole struck into the road’s verge and hung with dead men’s bones and ribbons of tattered cloth. There were few trees, the streams were frozen and snow blocked some of the passes. At night we sheltered in the huddled houses where we paid for our warmth with slivers of gold chopped from Cuneglas’s ingots. We dressed in furs. Ceinwyn and I, like my men, were swathed in lice-ridden wolf-pelts and deerskins, but Merlin wore a suit made from the coat of a great black bear. Nimue had grey otter skins that were much lighter than our furs, but even so she seemed not to feel the cold as the rest of us did. Nimue alone carried no weapons. Merlin had his black staff, a fearsome thing in battle, while my men had spears and swords and even Ceinwyn carried a light spear and had her long-bladed hunting knife scabbarded at her waist. She wore no gold and the folk who gave us shelter had no conception of her rank. They did notice her bright hair and assumed that she, like Nimue, was one of Merlin’s adepts. Merlin they loved, for they all knew of him and they brought their crippled children to be touched by his hand.

It took us six days to reach Caer Gei where Cadwallon, King of Gwynedd, was spending the winter. The caer itself was a hilltop fort, but under the fort’s shoulder there was a deep valley with tall trees growing from its steep sides and in the valley a wooden palisade circling a timber hall, some store-rooms and a score of sleeping huts, all of them ghosted white with snow and with long icicles hanging from their eaves. Cadwallon proved to be a sour old man while his hall was merely one third the size of Cuneglas’s hall and the press of warriors meant that its earth floor was already packed tight with beds. A space was grudgingly made for us and a corner screened for Nimue and Ceinwyn. That night Cadwallon gave us a feast, a poor thing of salted mutton and stewed carrots, but the best his stores could provide. He did generously offer to take Ceinwyn off our hands by making her his eighth wife, but he seemed neither offended nor disappointed when she refused. His seven existing wives were dark, sullen women who shared a round hut where they squabbled and persecuted each other’s children. It was a wretched place, Caer Gei, though a royal one, and it was hard to believe that Cadwallon’s father, Cunedda, had been the High King before Uther of Dumnonia. Gwynedd’s spears had fallen on lean times since those great days. It was hard to believe, too, that it was here, beneath the high peaks that were now brilliant with ice and snow, that Arthur had been raised. I went to see the house where his mother had been given shelter after Uther had rejected her and found it to be an earth-walled hall about the same size as our house in Cwm Isaf. It stood among fir trees whose boughs were bent low by snow, and it looked north towards the Dark Road. The house was now home to three spearmen, their families and livestock. Arthur’s mother had been half sister to King Cadwallon who was thus Arthur’s uncle, though Arthur’s birth had been illegitimate and the relationship could hardly be expected to yield many spears for Arthur’s spring campaign against the Saxons. Cadwallon, indeed, had sent men to fight against Arthur at Lugg Vale, but that gift of men had been a precaution to keep Powys’s friendship rather than because the King of Gwynedd hated Dumnonia. Most of the time Cadwallon’s spears faced north towards Lleyn.

The King summoned Byrthig, his Edling, to the feast so that he could tell us of Lleyn. Prince Byrthig was a short, squat man with a scar running from his left temple across his broken nose and down into his thick beard. He had only three teeth, which made his efforts to chew meat lengthy and messy. He would use his fingers to chafe the meat against his one front tooth, thus abrading the food into shreds that he washed down with mead, and the laborious work had left his bristling black beard filthy with meat juices and half chewed scraps. Cadwallon, in his gloomy manner, offered him as a husband to Ceinwyn and again seemed unmoved by her gentle refusal.

Diwrnach, Prince Byrthig told us, had his home at Boduan, a fort that lay far to the west in the peninsula of Lleyn. The King was one of the Irish Lords Across the Sea, but his war-band, unlike that of Oengus of Demetia, was not composed of men from a single Irish tribe but was a collection of fugitives from every tribe. ‘He welcomes whatever comes across the water, and the more murderous they are, the better,’ Byrthig told us. ‘The Irish use him to rid themselves of their outlaws and there have been many of those of late.’

‘The Christians,’ Cadwallon grumbled in curt explanation, then spat.

‘Lleyn is Christian?’ I asked in surprise.

‘No,’ Cadwallon snapped as though I should have known better. ‘But Ireland is bowing to the Christian God. Bowing in droves, and those who can’t stand that God flee to Lleyn.’ He pulled a scrap of bone from his mouth and inspected it gloomily. ‘We’ll have to fight them soon,’ he added.

‘Diwrnach’s numbers increase?’ Merlin asked.

‘So we hear, though we hear little enough,’ Cadwallon replied. He looked up as the heat in the hall melted a swathe of snow from the sloping roof. There was a scraping rumble, then a soft crash as the mass slid off the thatch.

‘Diwrnach,’ Byrthig explained, his voice made sibilant by his ravaged teeth, ‘asks only to be left alone. If we do not disturb him, he will only occasionally disturb us. His men come to take slaves, but we have few people left in the north now, and his men will not travel far, but if his war-band grows too large for Lleyn’s crops then he will seek new land somewhere.’

‘Ynys Mon is famous for its crops,’ Merlin said. Ynys Mon was the big island that lay off Lleyn’s northern coast.

‘Ynys Mon could feed a thousand,’ Cadwallon agreed, ‘but only if its people are spared to plough and reap, and its people are not spared. No one is. Any Briton with sense left Lleyn years ago, and the ones who are left crouch in terror. So would you if Diwrnach came visiting to search for what he wants.’

‘Which is?’ I asked.

Cadwallon looked at me, paused, then shrugged. ‘Slaves,’ he said.

‘In which,’ Merlin asked silkily, ‘you pay him tribute?’

‘A small price for peace,’ Cadwallon dismissed the accusation.

‘How much?’ Merlin demanded.

‘Forty a year,’ Cadwallon finally admitted. ‘Mostly orphaned children and maybe some prisoners. He’s happiest, though, with girls.’ He looked broodingly at Ceinwyn. ‘He has an appetite for girls.’

‘Many men do, Lord King,’ Ceinwyn answered drily.

‘But not like Diwrnach’s appetite,’ Cadwallon warned her. ‘His wizards have told him that a man armed with a shield covered with the tanned skin of a virgin girl will be invincible in battle.’ He shrugged.

‘Can’t say I’ve ever tried it myself.’

‘So you send him children?’ Ceinwyn said accusingly.

‘Do you know any other kind of virgin?’ Cadwallon retorted.

‘We think he’s touched by the Gods,’ Byrthig said, as though that explained Diwrnach’s appetite for virgin slaves, ‘for he seems mad. One of his eyes is red.’ He paused to grind a piece of grey mutton on his front tooth. ‘He covers his shields in skin,’ he went on when the meat had been reduced to a tissue,

‘then paints them with blood and that’s why his men call themselves the Bloodshields.’ Cadwallon made the sign against evil. ‘And some men say he eats the girls’ flesh,’ Byrthig went on, ‘but we don’t know that; who knows what the mad do?’

‘The mad are close to the Gods,’ Cadwallon growled. He was plainly terrified of his northern neighbour, and no wonder, I thought.

‘Some of the mad are close to the Gods,’ Merlin said. ‘Not all.’

‘Diwrnach is,’ Cadwallon warned him. ‘He does what he wants, to whom he wants, how he wants and the Gods keep him safe while he does it.’ Again I made the sign against evil, and suddenly wished I was back in far Dumnonia where there were lawcourts and palaces and long Roman roads.

‘With two hundred spears,’ Merlin said, ‘you could scour Diwrnach from Lleyn. You could wash him into the sea.’

‘We tried once,’ Cadwallon said, ‘and fifty of our men died of the flux in one week, and another fifty were shivering in their own excrement, and always his howling warriors circled us on ponies and their long spears showered out of the night. When we reached Boduan there was only a great wall hung with dying things that bled and screamed and twisted on their hooks and none of my men would scale that horror. Nor would I,’ he admitted. ‘And if I had, what then? He would have tied to Ynys Mon and it would have taken me days and weeks to find the ships to follow him over the water. I have neither the time, the spearmen, nor the gold to scour Diwrnach into the sea, so I give him children instead. It’s cheaper.’ He shouted for a slave to bring him more mead, then gave Ceinwyn a sour glance. ‘Give her to him,’ he said to Merlin, ‘and he might give you the Cauldron.’

‘I will give him nothing for the Cauldron,’ Merlin snapped. ‘Besides, he does not even know the Cauldron exists.’

‘He does now,’ Byrthig put in. ‘All Britain knows why you go north. And do you think his wizards don’t want to find the Cauldron?’

Merlin smiled. ‘Send your spearmen with me, Lord King, and we shall take both the Cauldron and Lleyn.’

Cadwallon snorted at that proposal. ‘Diwrnach, Merlin, teaches a man to be a good neighbour. I will let you travel my land, for I fear your curse if I don’t, but not one man of mine will go with you, and when your bones are buried in Lleyn’s sands I shall tell Diwrnach that your trespass was none of my doing.’

‘Will you tell him by which road we travel?’ Merlin asked, for we faced two roads now. One led around the coast and was the usual winter road north, while the other was the Dark Road that most men reckoned was impassable in winter. Merlin hoped that by using the Dark Road we could surprise Diwrnach and be gone from Ynys Mon almost before he knew we had even come. Cadwallon smiled for the only time that night. ‘He knows already,’ the King said, then glanced at Ceinwyn, the brightest figure in that smoke-dark hall. ‘And doubtless he looks forward to your coming.’

Did Diwrnach know we planned to use the Dark Road? Or was Cadwallon guessing? I spat anyway, to protect us all from evil. The solstice was due, the long night of the year when life ebbs, hope is bleak and the demons have dominion of the air, and that was when we would be on the Dark Road. Cadwallon thought us fools, Diwrnach waited for us, and we wrapped ourselves in fur and slept. The sun shone next morning, making the surrounding peaks into dazzling spikes of whiteness that hurt our eyes. The sky was almost clear and a strong wind blew snow from the ground to make clouds of glittering specks that wafted across the white land. We loaded the ponies, accepted the grudging gift of a sheepskin from Cadwallon, then marched towards the Dark Road that began just north of Caer Gei. It was a road without settlements, without farms, without a soul to offer us shelter; nothing but a rugged path through the wild mountain barrier that protected Cadwallon’s heartland from Diwrnach’s Bloodshields. Two poles marked the beginning of the road and both were topped by rag-draped human skulls from which long icicles clinked in the wind. The skulls faced north towards Diwrnach, two talismans to keep his evil beyond the mountains. I saw Merlin touch an iron amulet that hung around his neck as we passed between the twin skulls and remembered his dreadful promise that he would begin to die the moment we reached the Dark Road. Now, as our boots squeaked and crunched through the road’s undisturbed layer of snow, I knew that oath of death had begun its work. I watched him, but saw no signs of distress as, all that day, we climbed into the hills, sliding on snow and trudging in a cloud of our own misting breath. We slept that night in an abandoned shepherd’s hut that still blessedly had a ragged roof of old timbers and decaying straw with which we built a fire that flickered feebly in the snowy darkness.

Next morning we had gone no more than a quarter mile when a horn sounded above and behind us. We stopped, turned, and shaded our eyes to see a dark line of men cresting a hill down which we had slithered the previous evening. There were fifteen of them, all with shields, swords and spears, and when they saw they had gained our attention they half ran and half slid down the treacherous slope of snow. Their progress made great cloudy plumes that drifted westwards on the wind. My men, without orders from me, formed a line, unstrapped their shields and lowered their spears so that they formed a shield-wall across the road. I had given Cavan’s responsibilities to Issa and he growled at them to stand firm, but no sooner had he spoken than I recognized the curious device painted on one of the approaching shields. It was a cross, and that Christian symbol was carried by only one man I knew. Galahad.

‘Friends!’ I called to Issa, then broke into a run. I could see the approaching men clearly now, and they were all from those of my men who had been left in Siluria and forced to serve as Lancelot’s palace guard. Their shields still bore the device of Arthur’s bear, but Galahad’s cross led them. He was waving and shouting, and I was doing the same, so that neither of us heard a word the other spoke until we had already met and embraced. ‘Lord Prince,’ I greeted him, then embraced him again, for of all the friends I ever had in this world he was the best.

He had fair hair and a face as broad and strong as his half-brother Lancelot’s was narrow and subtle. Like Arthur he invited trust on sight, and if all Christians had been like Galahad I think I would have taken the cross in those early days. ‘We slept all night across the ridge,’ he gestured back up the road, ‘and half froze, while you must all have rested there?’ He pointed towards the wisp of smoke still drifting from our fire.

‘Warm and dry,’ I said, and then, when the newcomers had greeted their old companions, I embraced them all and gave their names to Ceinwyn. One by one they knelt and swore her loyalty. They had all heard how she had fled her betrothal feast to be with me, and they loved her for that and now held their naked sword blades for her royal touch. ‘What of the other men?’ I asked Galahad.

‘Gone to Arthur.’ He grimaced. ‘None of the Christians came, sadly. Except me.’

‘You think this is worth a pagan Cauldron?’ I asked, gesturing towards the cold road ahead.

‘Diwrnach lies at the road’s end, my friend,’ Galahad said, ‘and I hear he is a King as evil as anything that ever crawled from the devil’s pit. A Christian’s task is to fight evil, so here I am.’ He greeted Merlin and Nimue, and then, because he was a Prince and so of equal rank to Ceinwyn, embraced her. ‘You are a fortunate woman,’ I heard him whisper.

She smiled and kissed his cheek. ‘More fortunate now that you are here, Lord Prince.’

‘That’s true, of course.’ Galahad stepped back and looked from her to me, and from me to her. ‘All Britain speaks of you two.’

‘Because all Britain is stuffed with idle tongues,’ Merlin snapped in a surprising burst of shrewishness,

‘and we have a journey to make when you two have finished gossiping.’ His face was pinched and his temper short. I put it down to age and the hard road we walked in cold weather, and tried not to think of his death-oath.

The journey through the mountains took us two more days. The Dark Road was not long, but it was hard and it climbed up steep hills and went through gaping valleys where the smallest sound echoed hollow and cold from the ice-locked walls. We found an abandoned settlement to spend the second night on the road, a place of round stone huts that were huddled inside a wall the height of a man on which we set three guards to watch the glittering moonlit slopes. There was no fuel for a fire and so we sat close together and sang songs and told tales and tried not to think of the Bloodshields. Galahad gave us news of Siluria that night. His brother, he told us, had refused to occupy Gundleus’s old capital at Nidum because it was too far from Dumnonia and had no comforts other than a decaying Roman barrack block, so he had moved Siluria’s government to Isca, the huge Roman fort that lay beside the Usk at the very edge of Siluria’s territory and just a stone’s throw from Gwent. It was as close as Lancelot could get to Dumnonia while still staying in Siluria. ‘He likes mosaic floors and marble walls,’ Galahad said, ‘and there’s just enough of them at Isca to keep him satisfied. He’s gathered every Druid in Siluria there.’

‘There are no Druids in Siluria,’ Merlin growled. ‘None that are any good, anyway.’

‘Those who call themselves Druids, then,’ Galahad said patiently. ‘He has two he particularly values and he pays them to make curses.’

‘On me?’ I asked, touching the iron on Hywelbane’s hilt.

‘Among others,’ Galahad said, glancing at Ceinwyn and making the sign of the cross. ‘He’ll forget in time,’ he added, trying to reassure us.

‘He’ll forget when he’s dead,’ Merlin said, ‘and even then he’ll carry a grudge across the bridge of swords.’ He shivered, not because he feared Lancelot’s enmity, but because he was cold. ‘Who are these so-called Druids he particularly values?’

‘Tanaburs’s grandsons,’ Galahad said, and I felt an icy hand creep round my heart. I had killed Tanaburs, and though I had possessed the right to take his soul, it was still a brave fool who killed a Druid and Tanaburs’s dying curse still hovered about me.

We went slowly the next day, our pace held back by Merlin. He insisted he was well and refused any assistance, but his step faltered too often, his face looked yellow and haggard, and his breath came in short, harsh gasps. We had hoped to be over the last pass by nightfall, but we were still climbing towards it as the short day’s light faded. All afternoon the Dark Road had twisted uphill, though to call it a road was a mockery for it was nothing but a stony, dreadful path that crossed and re-crossed a frozen stream where the ice hung thick from the ledges of the frequent small waterfalls. The ponies kept slipping and sometimes refused to move at all; it seemed we spent more time supporting them than leading them, but as the last light drained cold into the west we reached the pass and it was just as I had seen it in my shivering dream on Dolforwyn’s summit. It was just as bleak, just as cold, though with no black ghoul barring the Dark Road that now dropped steeply onto Lleyn’s narrow coastal plain and then ran north to the shore.

And beyond that shore lay Ynys Mon.

I had never seen the blessed isle. I had heard of it all my life and known of its power and lamented the destruction worked on it by the Romans in the Black Year, but I had never seen it except in the dream. Now, in the winter’s dusk, it looked nothing like that lovely vision. It was not sunlit, but shadowed by cloud, so that the big isle looked dark and menacing, a threat made worse by the sullen glint of black pools that broke its low hills. The isle was almost free of snow, though its rocky edges were fretted white by a grey and miserable sea. I fell to my knees at the sight of the island, we all did except for Galahad, and even he finally went on one knee as a mark of respect. As a Christian he sometimes dreamed of going to Rome or even to far-off Jerusalem, if such a place really existed, but Ynys Mon was our Rome and our Jerusalem, and we were now in sight of its holy soil.

We were also now in Lleyn. We had crossed the unmarked border and the few settlements on the coastal plain beneath us were the holdings of Diwrnach. The fields were lightly covered with snow, smoke rose from huts, but nothing human seemed to move in that dark space and all of us, I think, were wondering how we were to go from the mainland to the island. ‘There are ferrymen on the straits,’ Merlin said, reading our thoughts. He alone of us had been to Ynys Mon, but it had been many years ago and long before he had ever known that the Cauldron still existed. He had gone there when Leodegan, Guinevere’s father, had ruled the land in the days before Diwrnach’s ragged ships had come from Ireland to sweep Leodegan and his motherless daughters out of their kingdom, in the morning,’ Merlin said, ‘we shall walk to the shore and pay our ferrymen. By the time Diwrnach knows we have reached his land, we shall already have gone.’

‘He’ll follow us to Ynys Mon,’ Galahad said nervously.

‘And we shall be gone again,’ Merlin said. He sneezed. He looked wretchedly cold. His nose was running, his cheeks were pale and from time to time he shivered uncontrollably, but he found some dusty herbs in a small leather pouch and he swallowed them with a handful of melted snow and insisted he was well.

He looked much worse next morning. We had spent that night in a cleft of the rocks where we had not dared light a fire, despite Nimue’s charm of concealment that she had worked with the help of a polecat’s skull we had found higher up the road. Our sentries had watched the coastal plain where three small glints of fire betrayed the presence of life, while the rest of us had clung together in the deep rocks where we shivered and cursed the cold and wondered if morning would ever dawn. It came at last with a seeping, leprous light that made the distant isle look darker and more menacing than ever. But Nimue’s charm seemed to have worked, for no spearmen guarded the Dark Road’s ending. Merlin was shaking now and was much too weak to walk, and so four of my spearmen carried him in a litter made of cloaks and spears as we slid and edged our way down to the first small wind-bent trees in the hedgerows of Lleyn. The road was sunken here and its ruts were frosted hard where it twisted between hunched oaks, thin hollies and the small neglected fields. Merlin was moaning and shuddering, and Issa wondered if we should turn back. ‘To cross the mountains again,’ Nimue said, ‘would surely kill him. We go on.’

We came to a fork in the road and there found our first sign of Diwrnach. It was a skeleton, bound together with horsehair ropes and hung from a pole so that its dry bones rattled in the brisk west wind. Three crows had been nailed to the post below the human bones and Nimue sniffed their stiffened bodies to decide what kind of magic had been imbued into their deaths. ‘Piss! Piss!’ Merlin managed to say from his litter. ‘Quick, girl! Piss!’ He coughed horribly, then turned his head to spit the sputum towards the ditch. ‘I won’t die,’ he said to himself, ‘I will not die!’ He lay back as Nimue squatted by the pole.

‘He knows we’re here,’ Merlin warned me.

‘Is he here?’ I asked, crouching beside him.

‘Someone is. Be careful, Derfel.’ He closed his eyes and sighed. ‘I am so old,’ he said softly, ‘so horribly old. And there’s badness here, all about us.’ He shook his head. ‘Get me to the island, that’s all, just reach the island. The Cauldron will cure all.’

Nimue finished, then waited to see which way the steam from her urine blew, and the wind took it towards the right-hand fork and that omen decided our path. Before we set off Nimue went to one of the ponies and found a leather bag from which she took a handful of elf bolts and eagle stones that she distributed among the spearmen. ‘Protection,’ she explained as she laid a snake stone in Merlin’s litter.

‘Onwards,’ she ordered us.

We walked all morning, our pace slowed by the need to carry Merlin. We saw no one and that absence of life put a dreadful fear into my men for it seemed as though we had come to a land of the dead. There were rowan and holly berries in the hedgerows, and thrushes and robins in the branches, but there were no cattle, no sheep and no men. We did see one settlement from which a wisp of smoke blew in the wind, but it was far off and no one appeared to be watching us from its circling wall. Yet men were in this dead land. We knew that when we paused to rest in a small valley where a stream trickled sluggishly between icy banks under a grove of small, black, wind-bent oaks. The intricate branches were each delicately limned with a white frost and we rested beneath them until Gwilym, one of the spearmen who was standing guard at the rear, called to me.

I went to the oaks’ edge to see that a fire had been set on the lower slope of the mountains. There were no flames visible, just a thick gruel of grey smoke that boiled fiercely before being snatched away by the west wind. Gwilym pointed to the smoke with his spear-blade, then spat to avert its evil. Galahad came to stand beside me. ‘A signal?’ he asked.

‘Probably.’

‘So they know we’re here?’ He crossed himself.

‘They know.’ Nimue joined us. She was carrying Merlin’s heavy black staff and she alone seemed to burn with energy in this cold, dead place. Merlin was sick, the rest of us were besieged by fear, but the deeper we pierced into Diwrnach’s black land the fiercer Nimue became. She was nearing the Cauldron, and the lure of it was like a fire in her bones. ‘They’re watching us,’ she said.

‘Can you hide us?’ I asked, wanting another of her concealment spells. She shook her head. ‘This is their land, Derfel, and their Gods are powerful here.’ She sneered as Galahad made the sign of the cross a second time. ‘Your nailed God won’t defeat Crom Dubh,’ she said.

‘He’s here?’ I asked fearfully.

‘Or one like him,’ she said. Crom Dubh was the Black God, a crippled and malevolent horror who gave dark nightmares. The other Gods, it was said, avoided Crom Dubh, which suggested we were alone in his power.

‘So we’re doomed,’ Gwilym said flatly.

‘Fool!’ Nimue hissed at him. ‘We’re only doomed if we fail to find the Cauldron. Then we’d all be doomed anyway. Are you going to watch that smoke all morning?’ she asked me. We walked on. Merlin could not speak any longer and his teeth chattered, even though we piled him with furs. ‘He’s dying,’ Nimue told me calmly.

‘Then we should find shelter,’ I said, ‘and build a fire.’

‘So we can all be warm while we’re slaughtered by Diwrnach’s spearmen?’ She scoffed at the idea.

‘He’s dying, Derfel,’ she explained, ‘because he’s close to his dream and because he made his bargain with the Gods.’

‘His life for the Cauldron?’ Ceinwyn, walking on my other side, asked the question.

‘Not quite,’ Nimue admitted. ‘But while you two were setting up your little house,’ she made that statement sarcastically, ‘we went to Cadair Idris. We made a sacrifice there, the old sacrifice, and Merlin pledged his life, hot for the Cauldron, but for the search. If we find the Cauldron, he’ll live, but if we fail then he dies and the shadow-soul of the sacrifice can claim Merlin’s soul for all time.’

I knew what the old sacrifice ‘was, though I had never heard of it being made in our time. ‘Who was the sacrifice?’ I asked.

‘No one you knew. No one we knew. Just a man.’ Nimue was dismissive. ‘But his shadow-soul is here, watching us, and it wants us to fail. It wants Merlin’s life.’

‘What if Merlin dies anyway?’ I asked.

‘He won’t, you fool! Not if we find the Cauldron.’

‘If I find it,’ Ceinwyn said nervously.

‘You will,’ Nimue said confidently.

‘How?’

‘You’ll dream,’ Nimue said, ‘and the dream will lead us to the Cauldron.’

And Diwrnach, I realized when we reached the straits dividing the mainland from the island, wanted us to find it. The signal fire told us his men had been watching us, but they had neither shown themselves nor tried to stop our journey, and that suggested Diwrnach knew of our quest and wanted it to succeed so that he could take the Cauldron for himself. There could be no other reason why he was making it so easy for us to reach Ynys Mon.

The straits were not wide, but the grey water swirled and sucked and foamed as it swept through the channel. The sea ran fast in those narrows, twisting itself into sullen whirlpools or else breaking white on hidden rocks, but the sea was not as frightening as the far shore that stood so utterly empty and dark and bleak, almost as if it waited to suck our souls away. I shivered as I looked at that distant grassy slope and could not help thinking of the far-off Black Day when the Romans had stood on this same rocky shore and that far bank had been thick with Druids who had hurled their dread curses at the foreign soldiers. The curses had failed, the Romans had crossed, and Ynys Mon had died, and now we stood in the same place in a last, desperate attempt to wind back the years and spool back the centuries of sadness and hardship so that Britain would be restored to its blessed state before the Romans came. It would be Merlin’s Britain then, a Britain of the Gods, a Britain without Saxons, a Britain full of gold and feasting halls and miracles.

We walked east towards the narrowest part of the straits and there, rounding a point of rock and beneath the earth loom of a deserted fortress, we found two boats hauled up on the pebbles of a tiny cove. A dozen men waited with the boats, almost as though they had expected us. ‘The ferrymen?’

Ceinwyn asked me.

‘Diwrnach’s boatmen,’ I said, and touched the iron in Hywel-bane’s hilt. ‘They want us to cross,’ I said, and I was afraid because the King was making it so easy for us. The sailors were quite unafraid of us. They were squat, hard-looking creatures with fish scales sticking to their beards and their thick woollen clothes. They carried no weapons other than their gutting knives and fish-spears. Galahad asked if they had seen any of Diwrnach’s spearmen, but they simply shrugged as if his language made no sense to them. Nimue spoke to them in her native Irish and they responded politely enough. They claimed to have seen no Blood-shields, but did tell her that we must wait until the tide had reached its height before we could cross. Only then, it seemed, were the straits safe for boats. We made Merlin a bed in one of the boats, then Issa and I climbed to the deserted fort and stared inland. A second pyre of smoke blew skyward from the valley of twisted oaks, but otherwise nothing had changed and no enemies were in sight. But they were there. You did not need to see their blood-daubed shields to know that they were close. Issa touched his spear-blade. ‘It seems to me. Lord,’ he said, ‘that Ymys Mon would be a good place to die.’

I smiled. ‘It would be a better place to live, Issa.’

‘But our souls will surely be safe if we die on the blessed isle?’ he asked anxiously.

‘They will be safe,’ I promised him, ‘and you and I will cross the bridge of swords together.’ And Ceinwyn, I promised myself, would be just a pace or two ahead of us, for I would kill her myself before any of Diwrnach’s men could lay their hands on her. I drew Hywel-bane, its long blade still smeared with the soot in which Nimue had written her charm, and I held its tip to Issa’s face. ‘Make me an oath,’ I ordered him.

He went on one knee. ‘Say it, Lord.’

‘If I die, Issa, and Ceinwyn still lives, then you must kill her with one sword stroke before Diwrnach’s men can take her.’

He kissed the sword’s tip. ‘I swear it, Lord.’

At high tide the swirling currents died away so that the sea lay still except for the wind-fretted waves that had floated the two boats up from the shingle. We lifted the ponies on board, then took our places. The boats were long and narrow and, as soon as we had settled amidst the sticky fishing nets, the boatmen gestured that we were to bail out the water that seeped between the tarred planks. We used our helmets to scoop the cold sea back to its place and I prayed to Manawydan, the sea God, that he would preserve us as the boatmen put their long oars between the tholes. Merlin shivered. His face was whiter that I had ever seen it, but touched by a nauseous yellow and smeared by flecks of foam that dribbled from the corners of his lips. He was not conscious, but muttered odd things in his delirium. The boatmen chanted a strange song as they pulled on their oars, but fell silent when they reached the middle of the straits. They paused there and one man in each boat gestured back towards the mainland. We turned. At first I could only see the dark strip of the shore beneath the snow-white and slate-black loom of the mountains beyond, but then I saw a ragged black thing moving just beyond the stony beach. It was a banner, mere fluttering strips of rags tied to a pole, but an instant after it appeared a line of warriors showed themselves above the strait’s bank. They laughed at us, their cackling coming clear through the cold wind above the sound of the lapping sea. They were all mounted on shaggy ponies and all were dressed in what appeared to be torn strips of ragged black cloth that caught the breeze and fluttered like pennants. They carried shields and the hugely long war spears that the Irish favoured, and neither the shields nor the spears frightened me, but there was something about their tattered, long-haired wildness that struck a sudden chill through me. Or perhaps that chill came from the sleet that had begun to spit on the west wind to dimple the sea’s grey surface.

The ragged, dark riders watched as our boats grounded on Ynys Mon. The boatmen helped us lift Merlin and the ponies safe ashore, then they ran their boats back into the sea.

‘Shouldn’t we have kept the boats here?’ Galahad asked me.

‘How?’ I asked. ‘We’d have to divide the men, some to guard the boats and some to go with Ceinwyn and Nimue.’

‘So how do we get off the island?’ Galahad asked.

‘With the Cauldron,’ I adopted Nimue’s confidence, ‘all things will be possible.’ I had no other answer to give him and dared not tell him the truth. That truth was that I felt doomed. I felt as though the curses of those ancient Druids were even now congealing around our souls. We struck north from the beach. Gulls screamed at us, whirling around us in the flying sleet as we climbed up from the rocks into a bleak moorland broken only by outcrops of stone. In the old days, before the Romans came to destroy Ynys Mon, the land had been thick with sacred oaks amongst which the greatest mysteries of Britain were performed. The news of those rituals governed the seasons in Britain, Ireland, and even Gaul, for here the Gods had come to earth, and here the link between man and the Gods had been strongest before it had been sundered by the short Roman stabbing swords. This was holy ground, but it was also difficult ground, for after just an hour’s walking we came to a vast bog that seemed to bar our path into the island’s interior. We ranged along the bog’s edge, seeking a path, but there was none; so, as the light began to fade, we used our spear-shafts to discover the firmest passage through the spiky tussocks of grass and the sucking, treacherous patches of marsh. Our legs were soaked in freezing mud and the sleet found its way inside our furs. One of the ponies became stuck and the other began to panic, so we unloaded both beasts, distributed their remaining burdens amongst ourselves, then abandoned them.

We struggled on, sometimes resting on our circular shields that served like shallow coracles to support our weight until, inevitably, the brackish water seeped over their edges and forced us to stand again. The sleet became harder and thicker, whipped by a rising wind that flattened the marsh grass and drove the cold deep into our bones. Merlin was shouting strange words and thrashing his head from side to side, while some of my men were weakening, sapped by the cold as well as by the malevolence of whatever Gods now ruled this ruined land.

Nimue was the first to reach the bog’s far side. She leapt from tussock to tussock, showing us a path, and finally reached firm ground where she jumped up and down to show us that safety was close. Then, for a few seconds, she froze before pointing Merlin’s staff back the way we had come. We turned to see that the dark riders were with us, only now there were more of them; a whole horde of tattered Bloodshields was watching us from the bog’s far side. Three ragged banners were hoisted above them, and one of those banners was lifted in ironic salute before the riders turned their ponies eastwards. ‘I should never have brought you here,’ I said to Ceinwyn.

‘You didn’t bring me, Derfel,’ she said. ‘I came of my own will.’ She touched a gloved finger to my face. ‘And we shall leave the same way, my love.’

We climbed up from the bog to find, beyond a low crest, a landscape of small fields that lay between lumpish moors and sudden rock outcrops. We needed a refuge for the night and found it in a settlement of eight stone huts that were circled by a wall the height of a spear. The place was deserted, though people clearly lived there for the small stone huts were swept clean and the ashes in the hearth were still just warm to the touch. We stripped the turf roof off one hut and cut the roof timbers into shreds with which we made a fire for Merlin, who was now shivering and raving. We set a guard, then stripped off our furs and tried to dry our sopping boots and wet leggings.

Then, as the very last of the light seeped from the grey sky, I went to stand on the wall and searched all about the landscape. I saw nothing.

Four of us stood guard for the first part of the night, then Galahad and another three spearmen watched through the rest of that rainy darkness and not one of us heard anything other than the wind and the crackle of the fire in the hut. We heard nothing, we saw nothing, yet in the morning’s first wan light there was a newly severed head of a sheep dripping blood on one part of the wall. Nimue angrily pushed the sheep’s head oft the wall’s coping, then screamed a challenge towards the sky. She took a pouch of grey powder and scattered it on the fresh blood, and afterwards she rapped the wall with Merlin’s staff and told us the malevolence had been countered. We believed her because we wanted to believe her, just as we wanted to believe that Merlin was not dying. But he was deathly pale, breathing shallowly and making no sound. We tried to feed him with the last of our bread, but he clumsily spat the crumbs out. ‘We must find the Cauldron today,’ Nimue said calmly, ‘before he dies.’

We gathered our burdens, hoisted our shields onto our backs, picked up our spears and followed her northwards.

Nimue led us. Merlin had told her all he knew of the sacred isle and that knowledge took us northwards all morning long. The Blood-shields appeared soon after we had left our shelter and, now that we neared our goal, they became bolder so that at any one time there were always a score in sight and sometimes three times that number. They formed a loose ring about us, but took care to stay well outside the range of our spears. The sleet had stopped with the dawn, leaving just a cold, damp wind that bent the grass on the moors and lifted the black tatters of the dark riders’ cloaks. It was just after midday that we came to the place Nimue called Llyn Cerrig Bach. The name means the ‘lake of little stones’ and it was a dark sheet of shallow water, surrounded by bogs. Here, Nimue said, the old Britons had held their most sacred ceremonies, and here too, she told us, our search would begin; but it seemed a bleak place in which to seek the greatest Treasure of Britain. To the west was a small, shallow neck of the sea beyond which lay another island, to the south and north were just farmlands and rocks, and to the east there rose a very small steep hill that was crowned with a group of grey rocks like a score of other such outcrops we had passed that morning. Merlin lay as if dead. I had to kneel beside him and put my ear close to his face to hear the tiny scratching of each laboured breath. I laid my hand on his forehead and found it was cold. I kissed his cheek. ‘Live, Lord,’ I whispered to him,

‘live.’

Nimue told one of my men to plant a spear in the ground. He forced the point into the hard soil, then Nimue took a half dozen cloaks and, by hanging them from the spear’s butt and weighting their hems with stones, she formed a kind of tent. The dark riders made a ring about us, but stayed far enough away so that they could not interfere with us, nor we with them.

Nimue groped under her otter skins and brought out the silver cup from which I had drunk on Dolforwyn and a small clay bottle stoppered with wax. She ducked under the tent and beckoned Ceinwyn to follow.

I waited and watched as the wind chased black ripples across the lake, then suddenly Ceinwyn screamed. She screamed again, terribly, and I started towards the tent, only to be stopped by Issa’s spear. Galahad, who as a Christian was not supposed to believe in any of this, stood beside Issa and shrugged at me. ‘We’ve come this far,’ he said. ‘We should see it to the end.’

Ceinwyn screamed again, and this time Merlin echoed the noise by uttering a faint and pathetic moan. I knelt beside him and stroked his forehead and tried not to think what horrors Ceinwyn dreamed inside the black tent.

‘Lord?’ Issa called to me.

I twisted round to see that he was looking southwards to where a new group of riders had joined the Bloodshields’ ring. Most of the newcomers were on ponies, but one man was mounted on a gaunt black horse. That man, I knew, had to be Diwrnach. His banner flew behind him; a pole on which was mounted a crosspiece and from the crosspiece there hung two skulls and a clutch of black ribbons. The King was cloaked in black and his black horse was hung with a black saddle cloth, and in his hand was a great black spear that he raised vertically into the air before riding slowly forward. He came alone and when he was fifty paces from us he unslung his round shield and ostentatiously turned it about to show that he did not come looking for a fight.

I walked to meet him. Behind me Ceinwyn gasped and moaned inside the tent about which my men made a protective ring.

The King was dressed in black leather armour beneath his cloak and wore no helmet. His shield looked flaky with rust and I supposed the flakes had to be the layers of dried blood, just as its leather covering had to be the flayed skin of a slave girl. He let the grim shield hang beside his long black sword scabbard as he curbed his horse and rested the great spear’s butt on the ground. ‘I am Diwrnach,’ he said.

I bowed my head to him. ‘I am Derfel, Lord King.’

He smiled. ‘Welcome to Ynys Mon, Lord Derfel Cadarn,’ he said, and doubtless he wanted to surprise me by knowing my full name and title, but he astonished me more by being a good-looking man. I had expected a hook-nosed ghoul, a thing from nightmare, but Diwrnach was in early middle age and had a broad forehead, a wide mouth and a short clipped black beard that accentuated his strong jawline. There was nothing mad about his appearance, but he did have one red eye and that was enough to make him fearsome. He leaned his spear against his horse’s flank and took an oatcake from a pouch. ‘You look hungry, Lord Derfel,’ he said.

‘Winter is a time for hunger, Lord King.’

‘But you will not refuse my gift, surely?’ He broke the oatcake into halves and tossed one half to me.

‘Eat.’

I caught the oatcake, then hesitated. ‘I am sworn not to eat, Lord King, till my purpose is finished.’

‘Your purpose!’ he teased me, then slowly put his half of the oatcake into his mouth. ‘It wasn’t poisoned, Lord Derfel,’ he said when it was eaten.

‘Why should it be, Lord King?’

‘Because I am Diwrnach and I kill my enemies in so many ways.’ He smiled again. ‘Tell me about your purpose, Lord Derfel.’

‘I come to pray, Lord King.’

‘Ah!’ he said, drawing the sound out as if to suggest that I had cleared up all the mystery. ‘Are prayers said in Dumnonia so very ineffective?’

‘This is holy ground, Lord King,’ I said.

‘It is also my ground, Lord Derfel Cadarn,’ he said, ‘and I believe strangers should seek my permission before they dung its soil or piss on its walls.’

‘If we have offended you, Lord King,’ I said, ‘then we apologize.’

‘Too late for that,’ he said mildly. ‘You are here now, Lord Derfel, and I can smell your dung. Too late. So what shall I do with you?’ His voice was low, almost gentle, suggesting that here was a man who would see reason very easily. ‘What shall I do with you?’ he asked again, and I said nothing. The ring of dark riders was unmoving, the sky was leaden with cloud and Ceinwyn’s moans had subsided to small whimpers. The King lifted his shield, not in threat but because its weight rested uncomfortably on his hip, and I saw with horror that the skin of a human arm and hand hung from its lower edge. The wind stirred the fat fingers of the hand. Diwrnach saw my horror and smiled. ‘She was my niece,’ he said, then he stared past me and another slow smile showed on his face. ‘The vixen is out of the covert. Lord Derfel,’ he said.

I turned to see that Ceinwyn had come out from under the tent.

She had discarded her wolfskins and was dressed in the bone-white dress she had worn to her betrothal feast, its hems still soiled by the mud she had kicked onto the linen when she had run away from Caer Sws. She was barefoot, her golden hair had been unloosed and to me it seemed she was in a trance. ‘The Princess Ceinwyn, I believe,’ Diwrnach said.

‘Indeed, Lord King.’

‘And still a maid, I hear?’ the King asked. I said nothing in answer. Diwrnach leaned forward to ruffle his horse’s ears fondly. ‘It would have been courteous of her, do you not think, to have greeted me when she arrived in my country?’

‘She too has prayers to say, Lord King.’

‘Then let us hope they work.’ He laughed. ‘Give her to me, Lord Derfel, or else you will die the slowest of deaths. I have men who can take the skin from a man inch by inch until he is nothing but a thing of raw flesh and blood and yet still he can stand. He can even walk!’ He patted his horse’s neck with a black-gloved hand, then smiled on me again. ‘I have choked men on their own dung, Lord Derfel, I have pressed them beneath the stones, I have burned them, I have buried them alive, I have bedded them down with vipers, I have drowned them, I have starved them and I have even frightened them to death. So many interesting ways, but just give the Princess Ceinwyn to me, Lord Derfel, and I will promise you a death as swift as a bright star’s fall.’

Ceinwyn had started to walk westwards and my men had snatched up Merlin’s litter, their cloaks, weapons and bundles, and were now going with her. I looked up at Diwrnach. ‘One day, Lord King,’ I said, ‘I will put your head in a pit and bury it in slave dung.’ I walked away from him. He laughed. ‘Blood, Lord Derfel!’ he shouted after me. ‘Blood! It’s what the Gods feed on, and yours will make a rich brew! I’ll make your woman drink it in my bed!’ And with that he kicked back his spurred boots and wheeled his horse towards his men.

‘Seventy-four of them,’ Galahad told me as I caught up with him. ‘Seventy-four men and spears. And we are thirty-six spears, one thing man and two women.’

‘They won’t attack yet,’ I reassured him. ‘They’ll wait till we’ve discovered the Cauldron.’

Ceinwyn must have been freezing in her thin dress and without any boots, but she was sweating as if it was a summer’s day as she staggered across the grass. She was finding it difficult to stand, let alone walk, and she was twitching just as I had twitched on Dolforwyn’s summit after drinking from the silver cup; but Nimue was beside her, talking to her and supporting her, but also, oddly, tugging her away from the direction she wanted to take. Diwrnach’s dark riders were keeping pace with us, a moving ring of Bloodshields that moved across the island in a loose, wide circle that was centred on our small party. Ceinwyn, despite her dizziness, was almost running now. She seemed barely conscious and was mouthing words I could not catch. Her eyes looked empty. Nimue constantly dragged her to one side, making her follow a sheep path that twisted north about the knoll that was crowned with grey stones, but the closer we came to those high and lichen-covered rocks the more Ceinwyn resisted until Nimue was forced to use all her wiry strength to keep her on the narrow path. The front edge of the ring of dark riders had already gone past the steep knoll so that it, like us, lay within their circle. Ceinwyn was whimpering and protesting, then she began to hit at Nimue’s hands, but Nimue held her hard and dragged her on, and all the while Diwrnach’s men moved with us.

Nimue waited until the path was at its closest point to the steep crest of rocks, then at last she let Ceinwyn run free. ‘To the rocks!’ she shrieked. ‘All of you! To the rocks! Run!’

We ran. I saw then what Nimue had done. Diwrnach dared not touch us until he knew where we were going and if he had seen Ceinwyn heading for the rocky knoll he would surely have sent a dozen spearmen to garrison its summit, then sent the rest of his men to capture us. But now, thanks to Nimue’s cleverness, we would have the steep jumble of huge boulders to protect us, the same boulders, if Ceinwyn was right, that had protected the Cauldron of Clyddno Eiddyn through more than four and a half centuries of gathering darkness. ‘Run!’ Nimue screamed, and all about us the ponies were being whipped inwards as the ring of dark riders closed to cut us off.

‘Run!’ Nimue shrieked again. I was helping to carry Merlin, Ceinwyn was already clambering up the rocks and Galahad was shouting at men to find themselves places where they could stand amidst the stones and use their spears. Issa stayed with me, his spear ready to cut down any dark rider who came close. Gwilym and three others snatched Merlin from us and carried him to the foot of the rocks just as the two leading Bloodshields reached us. They shrieked a challenge as they kicked their ponies up the hill, but I knocked the first man’s long spear aside with my shield then swung my own spear so that its steel blade cracked like a club across the pony’s skull. The beast screamed and fell sideways and Issa slid his spear into the rider’s belly while I slashed my spear back at the second rider. His spear-shaft clattered on mine, then he was past me, but I managed to seize a handful of his long tattered ribbons and so dragged him backwards off the small beast. He flailed at me as he fell. I put a boot on his throat, raised the spear and rammed it hard down at his heart. There was a leather breastplate beneath his ragged tunic, but the spear cut through both and suddenly his black beard was frothing with a bloody foam.

‘Back!’ Galahad shouted at us, and Issa and I tossed our shields and spears to the men already safe on the high rocks’ summit, then clambered up ourselves. A black-shafted spear clattered on the rocks beside me, then a strong hand reached down, grasped my wrist and hauled me up. Merlin had been similarly dragged up the rocks, then unceremoniously dropped in the summit’s centre where, like a cup crowned by the ring of vast boulders, there was a deep stony hollow. Ceinwyn was in that hollow, scrabbling like a frantic dog at the little stones that filled the cup. She had vomited and her hands obliviously scratched among the mix of vomit and small cold stones.

The knoll was ideal for defence. Our enemy could only climb the rocks with hands and feet, while we could shelter in the clefts of the summit’s crown to deal with them as they appeared. A few tried to reach us, and those men screamed as the blades slashed into their faces. A shower of spears was thrown at us, but we held our shields aloft and the weapons clattered harmlessly away. I put six men down in the central hollow and they used their shields to shelter Merlin, Nimue and Ceinwyn while the other spearmen guarded the summit’s outer rim. The Bloodshields, their ponies abandoned, made one more rush and for a few moments we were busy stabbing and lunging. One of my men took a spear cut on his arm during that brief fight, but otherwise we were unhurt, while the dark riders carried four dead and six wounded men back to the knoll’s foot. ‘So much,’ I told my men, ‘for shields made of virgins’ skins.’

We waited for another attack, but none came. Instead Diwrnach walked his horse up the slope alone.

‘Lord Derfel?’ he called in his deceptively pleasant voice and, when I showed my face between two rocks, he offered me his placid smile. ‘My price has risen,’ the King said. ‘Now, in return for your swift death, I demand the Princess Ceinwyn and the Cauldron. It is the Cauldron that you’ve come for, is it not?’

‘It is all Britain’s Cauldron, Lord King,’ I said.

‘Ah! And you think I would be an unworthy guardian?’ He shook his head sadly. ‘Lord Derfel, you do insult a man so very easily. What was it to be? My head in a pit being dunged by slaves? What a paltry imagination you do have. Mine, I fear, sometimes seems excessive, even to me.’ He paused and glanced towards the sky as if judging how much daylight remained. ‘I have few enough warriors, Lord Derfel,’ he went on in his reasonable voice, ‘and I do not want to lose any more of them to your spears. But sooner or later you must come out of the rocks and I shall wait for you, and as I wait I shall let my imagination rise to new heights of achievement. Give the Princess Ceinwyn my greetings, and tell her I so look forward to a closer acquaintance.’ He raised his spear in mocking salute, then rode back to the ring of dark riders who now had the knoll entirely surrounded.

I let myself down into the bowl in the knoll’s centre and saw that whatever we found here would prove too late for Merlin; death was plain on his face. His jaw was hanging open and his eyes were as empty as the space between the worlds. His teeth chattered once to show he was still alive, but that life was a thread now and it was fraying fast. Nimue had taken Ceinwyn’s knife and was scratching and clawing at the small stones that filled the hollow of the summit, while Ceinwyn, her face looking exhausted, had slumped against a rock where she shivered and watched as Nimue dug. Whatever trance had possessed Ceinwyn had now passed and I helped her clean the mess from her hands, found her suit of wolfskins and covered her over.

She pulled on her gloves. ‘I had a dream,’ she whispered to me, ‘and saw the end.’

‘Our end?’ I asked in alarm.

She shook her head. ‘Ynys Mon’s end. There were lines of soldiers, Derfel, in Roman skirts and breastplates and bronze helmets. Great hunting lines of soldiers and their sword arms were bloody to their shoulders because they just killed and killed. They came through the forests in a great line, just killing. Arms going up and down, and all the women and children running away, only there was nowhere to run and the soldiers just closed on them and chopped them down. Little children, Derfel!’

‘And the Druids?’

‘All dead. All but three, and they brought the Cauldron here. They’d made a pit for it already, you see, before the Romans crossed the water, and they buried it here, then covered it with stones from the lake, and after that they put ashes on the stones and lifted fire with their bare hands so that the Romans would think nothing could be buried here. And when that was done they walked singing into the woods to die.’

Nimue hissed in alarm, and I twisted around to see that she had uncovered a small skeleton. She fumbled among her otter skins and brought out a leather bag that she tore open to take out two dried plants. They had spiky leaves and small, faded golden flowers and I knew she was placating the dead bones with a gift of asphodel. ‘It was a child they buried,’ Ceinwyn explained the smallness of the bones,

‘the guardian of the Cauldron and the daughter of one of the three Druids. She had short hair and a fox-skin bracelet on her wrist, and they buried her alive so she would guard the Cauldron till we found it.’

Nimue, the dead soul of the Cauldron’s guardian placated by the asphodel, dragged the girl’s bones from the small stones, then attacked the deepening hole with her knife and snapped at me to come and help her. ‘Dig with your sword, Derfel!’ she ordered, and I obediently thrust Hywelbane’s tip into the pit. And found the Cauldron.

At first it was just a glimpse of dirty gold, then a sweep of Nimue’s hand showed a heavy golden rim. The Cauldron was much bigger than the hole we had made and so I ordered Issa and another man to help make it wider. We scooped the stones out with our helmets, working in a desperate haste for Merlin’s soul was flickering out the very last of his long life. Nimue was panting and weeping as she attacked the tight packed stones that had been brought to this summit from the sacred lake of Llyn Cerrig Bach.

‘He’s dead!’ Ceinwyn cried. She was kneeling beside Merlin.

‘He is not dead!’ Nimue spat between clenched teeth, then she seized the golden rim with both her hands and began to tug at the Cauldron with all her strength. I joined her, and it seemed impossible that the huge vessel could be moved with all the weight of stones that still pressed into its deep belly but somehow, with the Gods’ help, we shifted that great thing of gold and silver out of its dark pit. And thus we brought the lost Cauldron of Clyddno Eiddyn into the light. It was a great bowl as wide as a man’s outstretched hands and as deep as the blade of a hunting knife. It was made of thick uneven silver, stood on three short golden legs and was decorated with lavish traceries of gold. Three golden hoops were fixed to its rim so that it could be hung above a fire. It was the greatest Treasure of Britain and we ripped it from its grave, shedding stones, and I saw how the gold that decorated it was shaped into warriors and Gods and deer. But we had no time to admire the Cauldron, for Nimue frantically scattered the last stones from its belly and placed it back in the hole before tearing the black furs from Merlin’s body. ‘Help me!’ she screamed, and together we rolled the old man into the pit and down into the belly of the great silver bowl. Nimue tucked his legs inside the golden rim and laid a cloak over him. Only then did Nimue lean back against the boulders. It was freezing, but her face was shining with sweat.

‘He’s dead,’ Ceinwyn said in a small, frightened voice.

‘No,’ Nimue insisted tiredly, ‘no, he’s not.’

‘He was cold!’ Ceinwyn protested. ‘He was cold and there was no breath.’ She clung to me and began weeping softly. ‘He’s dead.’

‘He lives,’ Nimue said harshly.

It had begun to rain again; a small, spitting, wind-hurried rain that slicked the stones and beaded our bloodied spear-blades. Merlin lay shrouded and unmoving in the Cauldron’s pit, my men watched the enemy across the tops of the grey stones, the dark riders ringed us and I wondered what madness had brought us to this miserable place at the dark cold end of Britain.

‘So what do we do now?’ Galahad asked.

‘We wait,’ Nimue snapped, ‘we just wait.’

I will never forget the cold of that night. Frost made crystals on the rock and to touch a spear-blade was to leave a scrap of skin frozen to the steel. It was so bitterly cold. The rain turned to snow at dusk, then stopped, and after the snow’s passing the wind dropped and the clouds sailed off to the east to reveal an enormous moon rising full above the sea. It was a moon full of portent; a great swollen silver ball that was hazed by a shimmer of distant cloud above an ocean crawling with black and silver waves. The stars had never seemed so bright. The great shape of Bel’s chariot blazed above us, eternally chasing the constellation we called the trout. The Gods lived among the stars and I sent a prayer winging up through the cold air in the hope that it would reach those far bright fires. Some of us dozed, but it was the shallow sleep of weary, cold and frightened men. Our enemies, ringing the knoll with their spears, had made fires. Ponies brought the Bloodshields fuel and the flames burned vast in the night to spew sparks into the clear sky.

Nothing moved in the Cauldron’s pit where Merlin’s cloaked body was shadowed from the moon by the loom of high rock where we took turns to watch the riders’ shapes against the fires. At times a long spear would fly out of the night and its head would glitter in the moonlight before the weapon clattered harmlessly against the stones.

‘So what will you do with the Cauldron now?’ I asked Nimue.

‘Nothing till Samain,’ she said dully. She lay crumpled near the heap of discarded bundles that had been thrown into the summit’s hollow, her feet resting on the spoil we had scrabbled so desperately from the pit. ‘Everything has to be right, Derfel. The moon must be full, the weather right and all the thirteen Treasures assembled.’

‘Tell me of the Treasures,’ Galahad said from the hollow’s farther side. Nimue spat. ‘So you can mock us, Christian?’ she challenged him.

Galahad smiled. ‘There are thousands of folk, Nimue, who mock you. They say the Gods are dead and that we should put our faith in men. We should follow Arthur, they say, and they believe your search for cauldrons and cloaks and knives and horns is so much nonsense that died with Ynys Mon. How many Kings of Britain would send you men for this search?’ He stirred, trying to find some comfort in this cold night. ‘None, Nimue, none, because they mock you. It’s all too late, they say. The Romans changed everything and sensible men say that your Cauldron is as dead as Ynys Trebes. The Christians say you are doing the devil’s work, but this Christian, dear Nimue, carried his sword to this place and for that, dear lady, you owe me at least civility.’

Nimue was not used to being reprimanded, except perhaps by Merlin, and she stiffened at Galahad’s mild rebuke, but then at last she relented. She pulled Merlin’s bearskin about her shoulders and hunched forward. ‘The Treasures,’ she said, ‘were left to us by the Gods. It was long ago, when Britain was quite alone in all the world. There were no other lands; just Britain and a wide sea that was covered by a great mist. There were twelve tribes of Britain then, and twelve Kings and twelve feasting halls and just twelve Gods. Those Gods walked as we do on the land and one of them, Bel, even married a human; our Lady here,’ she gestured towards Ceinwyn, who was listening as avidly as any of the spearmen, ‘is descended from that marriage.’

She paused as a shout sounded from the ring of fires, but the shout presaged no threat and silence fell on the night again as Nimue went on with her tale. ‘But other Gods who were jealous of the twelve who ruled Britain came from the stars and tried to take Britain from the twelve Gods, and in the battles the twelve tribes suffered. One spear stroke from a God could kill a hundred people, and no earthly shield could stop a God’s sword, so the twelve Gods, because they loved Britain, gave the twelve tribes twelve Treasures. Each Treasure was to be kept in a royal hall and the presence of the Treasure would keep the spears of the Gods from falling on the hall or any of its people. They were not grand things. If the twelve Gods had given us splendid things then the other Gods would have seen them, guessed their purpose and stolen them for their own protection. So the twelve gifts were just common things: a sword, a basket, a horn, a chariot, a halter, a knife, a whetstone, a sleeved coat, a cloak, a dish, a throw-board and a warrior ring. Twelve ordinary things, and all the Gods asked of us was that we should cherish the twelve Treasures, to keep them safe and offer them honour, and in return, as well as having the protection of the Treasures, each tribe could use its gift to summon their God. They were allowed one summons a year, only one, but that summons gave the tribes some power in the terrible war of the Gods.’

She paused and pulled the furs tighter about her thin shoulders. ‘So the tribes had their Treasures,’ she went on, ‘but Bel, because he loved his earthly girl so very much, gave her a thirteenth Treasure. He gave her the Cauldron and he told her that whenever she began to grow old she had only to fill the Cauldron with water, immerse herself, and she would be young again. Thus, in all her beauty, she could walk beside Bel for ever and ever. And the Cauldron, as you saw, is splendid; it is gold and silver, lovely beyond anything man can make. The other tribes saw it and were jealous, and in this way the wars of Britain began. The Gods warred in the air and the twelve tribes warred on earth, and one by one the Treasures were captured, or else they were bartered for spearmen, and in their anger the Gods withdrew their protection. The Cauldron was stolen, Bel’s lover grew old and died, and Bel placed a curse on us. The curse was the existence of other lands and other peoples, but Bel promised us that if one Samain we drew the twelve Treasures of the twelve tribes together again and made the proper rites, and filled the thirteenth Treasure with the water that no man drinks but without which no man can live, then the twelve Gods would come to our aid again.’ She stopped, shrugged and looked at Galahad. ‘There, Christian,’

she said, ‘that is why your sword came here.’

There was a long silence. The moonlight slid down the rocks, creeping ever nearer to the pit where Merlin lay beneath the thin cover of a cloak.

‘And you have all twelve Treasures?’ Ceinwyn asked.

‘Most,’ Nimue said evasively. ‘But even without the twelve, the Cauldron has immense power. Vast power. More power than all the other Treasures together.’ She looked belligerently across the pit towards Galahad. ‘And what will you do, Christian, when you see that power?’

Galahad smiled. ‘I shall remind you that I carried my sword in your quest,’ he said softly.

‘We all did. We are the warriors of the Cauldron,’ Issa said quietly, displaying a streak of poetry I had not suspected in him, and the other spearmen smiled. Their beards were frosted white, their hands were wrapped in strips of cloth and fur and their eyes looked hollow, but they had found the Cauldron and the pride of that achievement filled them, even if, at first light, they must face the Bloodshields and the dawning knowledge that we were all doomed.

Ceinwyn leaned against me, sharing my wolfskin cloak. She waited till Nimue was sleeping, then tipped her face up to mine. ‘Merlin’s dead, Derfel,’ she said in a small sad voice.

‘I know,’ I said, for there had been neither motion nor sound from the Cauldron’s pit.

‘I felt his face and hands,’ she whispered, ‘and they were cold as ice. I put my knife blade beside his mouth and it didn’t cloud. He’s dead.’

I said nothing. I loved Merlin because he had stood to me as a father and I could not truly believe he had died at this moment of his triumph, but nor could I find the hope to see his life’s soul again. ‘We should bury him here,’ Ceinwyn said softly, ‘inside his Cauldron.’ Again I did not speak. Her hand found mine. ‘What shall we do?’ she asked.

Die, I thought, but still I said nothing.

‘You will not let me be taken?’ she whispered.

‘Never,’ I said.

‘The day I met you, Lord Derfel Cadarn,’ she said, ‘was the best day of my life,’ and that made my tears come, but whether they were tears of joy or a lament for all that I would lose in the next cold dawn, I do not know.

I fell into a shallow sleep and dreamed I was trapped in a bog and surrounded by dark riders who were magically able to move across the soaking land, and then I found I could not raise my shield arm and I saw the sword coming down on my right shoulder and I woke with a start, reaching for my spear, only to see that it was Gwilym who had inadvertently touched my shoulder as he clambered up the rock to take over guard duty. ‘Sorry, Lord,’ he whispered.

Ceinwyn slept in the crook of my arm and Nimue was huddled on my other side. Galahad, his fair beard whitened by frost, was snoring gently and my other spearmen either dozed or else lay in cold stupefaction. The moon was almost above me now, its light slanting down to show the stars painted on my men’s stacked shields and on the stony side of the pit we had scrabbled in the summit’s hollow. The mist that had shimmered the moon’s swollen face when it had hung just above the sea was gone and now it was a pure, hard, clear, cold disc etched as sharp as a newly minted coin. I half remembered my mother telling me the name of the man in the moon, but I could not pin the memory down. My mother was a Saxon and I had been in her belly when she had been captured in a Dumnonian raid. I had been told she was still alive in Siluria, but I had not seen her since the day the Druid Tanaburs had snatched me from her arms and tried to kill me in the death pit. Merlin had raised me after that, and I had become a Briton, a friend of Arthur and the man who had taken the star of Powys from her brother’s hall. What an odd thread of life, I thought, and how sad that it would be cut short here on Britain’s sacred isle.

‘I don’t suppose,’ Merlin said, ‘that there is any cheese?’

I stared at him, thinking I must still be dreaming.

‘The pale sort, Derfel,’ he said anxiously, ‘that crumbles. Not the hard dark yellow stuff. I can’t abide that hard dark yellow cheese.’

He was standing in the pit and peering earnestly at me with the cloak that had covered his body now hanging about his shoulders like a shawl.

‘Lord?’ I said in a tiny voice.

‘Cheese, Derfel. Did you not hear me? I am hungry for cheese. We did have some. It was wrapped in linen. And where is my staff? A man lies down for a small sleep and immediately his staff is stolen. Is there no honesty left? It’s a terrible world. No cheese, no honesty and no staff.’

‘Lord!’

‘Stop shouting at me, Derfel. I’m not deaf, just hungry’

‘Oh, Lord!’

‘Now you’re weeping! I do hate blubbing. All I ask is a morsel of cheese and you start weeping like a child. Ah, there’s my staff. Good.’ He plucked it from beside Nimue and used it to hoist himself out of the pit. The other spearmen were awake now and gaping at him. Then Nimue stirred and I heard Ceinwyn gasp. ‘I suppose, Derfel,’ Merlin said as he began rummaging in the piled bundles to find his cheese, ‘that you’ve landed us in a predicament? Surrounded, are we?’

‘Yes, Lord.’

‘Outnumbered?’

‘Yes, Lord.’

‘Dear me, Derfel, dear me. And you call yourself a lord of warriors? Cheese! Here it is. I knew we had some. Wonderful.’

I pointed a tremulous finger at the pit. ‘The Cauldron, Lord.’ I wanted to know whether the Cauldron had performed a miracle, but I was too confused with wonder and relief to be coherent.

‘And a very nice Cauldron it is, Derfel. Capacious, deep, full of the qualities one wants in a cauldron.’

He bit a hunk of the cheese. ‘I am famished!’ He took another bite, then settled back against the rocks and beamed at us all. ‘Outnumbered and surrounded! Well, well! Whatever next?’ He crammed the last of the cheese into his mouth then brushed the crumbs from his hands. He bestowed a special smile on Ceinwyn, then held out a long arm for Nimue. ‘All well?’ he asked her.

‘All well,’ she said calmly as she settled into his embrace. She alone did not seem surprised by his appearance or by his evident health.

‘Except that we’re surrounded and outnumbered!’ he said mockingly. ‘What shall we do? Usually the best thing to do in an emergency is to sacrifice someone.’ He peered expectantly about the stunned circle of men. His face had recovered its colour and all his old mischievous energy had returned. ‘Derfel, perhaps?’

‘Lord!’ Ceinwyn protested.

‘Lady! Not you! No, no, no, no, no. You’ve done enough.’

‘No sacrifice, Lord,’ Ceinwyn pleaded.

Merlin smiled. Nimue appeared to have gone to sleep in his arm, but for the rest of us there could be no more sleep. A spear clattered on the lower rocks and the sound made Merlin hold his staff out to me.

‘Climb to the top, Derfel, and hold my staff to the west. To the west, remember, not the east. Try and do something right for a change, will you? Of course, if you want a job done properly then you should always do it yourself, but I don’t want to wake Nimue. Off you go.’

I took the staff and clambered up the rocks to stand on the highest point of the knoll and there, following Merlin’s instructions, I pointed it towards the distant sea.

‘Don’t prod with it!’ Merlin called up to me. ‘Point it! Feel its power! It isn’t an ox goad, boy, it’s a Druid’s staff!’

I held the staff westward. Diwrnach’s dark riders must have scented magic, for his own sorcerers suddenly howled and a pack of spearmen scuttled up the slope to hurl their weapons at me.

‘Now,’ Merlin called as the spears fell beneath me, ‘give it power, Derfel, give it power!’ I concentrated on the staff, but truly felt nothing, though Merlin seemed satisfied with my effort. ‘Bring it down now,’ he said, ‘and get some rest. We have a fair walk to make in the morning. Is there any more cheese? I could eat a sackful!’

We lay in the cold. Merlin would not discuss the Cauldron, nor his illness, but I sensed the change of mood in all of us. We were suddenly hopeful. We would live, and it was Ceinwyn who first saw the way of our salvation. She prodded my side, then pointed up at the moon, and I saw that what had been a clear clean shape was now hazed by a torque of shimmering mist. That misty torque looked like a ring of powdered gems, so hard and bright did those tiny points shine about the full silver moon. Merlin did not care about the moon, he was still talking of cheese. ‘There used to be a woman in Dun Seilo who made the most wonderful soft cheese,’ he told us. ‘She wrapped it in nettle leaves as I remember, then insisted it spent six months sitting in a wooden bowl that had been steeped in ram’s urine. Ram’s urine! Some people do possess the most absurd superstitions, but all the same her cheese was very good.’ He chuckled. ‘She made her poor husband collect the urine. How did he do it? I never liked to ask. Grasp it by the horns and tickle, do you think? Or maybe he used his own and never told her. I would have done. Is it getting warmer, do you think?’

The glittering ice mist about the moon had faded, but the fading had not made the moon’s edges any duller. Instead they were being diffused by a gentler mist that was now being wafted on a small west wind that was indeed warmer. The bright stars were hazed, the crystal frost on the rocks was melting to a wet sheen and we had all stopped shivering. Our spear-points could be touched again. A fog was forming.

‘The Dumnonians, of course, insist their cheese is the very finest in Britain,’ Merlin said earnestly, as though none of us had anything better to do than listen to a lecture on cheese, ‘and, admittedly, it can be good, but too often it is hard. I remember Uther broke a tooth once on a piece of cheese from a farm near Lindinis. Clean in two! Poor fellow was in pain for weeks. He never could abide having a tooth pulled. He insisted I work some magic, but it’s a strange thing, magic never works with teeth. Eyes, yes, bowels, every time, and even brains sometimes, though there’s few enough of those in Britain these days. But teeth? Never. I must work on that problem when I have some time. Mind you, I do enjoy pulling teeth.’ He smiled extravagantly, showing off his own rare set of perfect teeth. Arthur was similarly blessed, but the rest of us were plagued by toothaches.

I looked up to see that the topmost rocks were almost hidden by the fog that was thickening by the minute. It was a Druid’s fog, brewing dense and white beneath the moon and smothering the whole of Ynys Mon in its thick cloak of vapour.

‘In Siluria,’ Merlin said, ‘they serve a pale bowl of slops and call it cheese. It’s so repellent that even the mice won’t eat it, but what else does one expect of Siluria? Was there something you wished to say to me, Derfel? You look excited.’

‘Fog, Lord,’ I said.

‘What an observant man you are,’ he said admiringly. ‘So perhaps you would pull the Cauldron from the pit? It’s time we went, Derfel, it’s time we went.’

And so we did.
