False Gods

SIX Land of decay Dead things Glory of Terra

The Astartes spread out through the fog, moving as swiftly as the boggy conditions allowed and following the source of the vox signal. Horus led from the front, a living god marching tall through the stinking quagmires and rank swamps of Davin's moon, untroubled by the noxious atmosphere. He disdained the wearing of a helmet, his superhuman physique easily able to withstand the airborne poisons.

Four blocks of Astartes marched, phalanx-like, into the mists, with each member of the Mournival leading nearly two hundred warriors. Behind them came the soldiers of the Imperial army, company after company of red-jacketed warriors with gleaming lasguns and silver tipped lances. Each man was equipped with rebreather apparatus after it was discovered that their mortal constitutions were unable to withstand the moon's toxic atmosphere. Initial landings of armour proved to be disastrous, as tanks sank into the marshland and dropships found themselves caught in the sucking mud.

Though the greatest of all the engines of war were those that emerged from the Mechanicum landers. Even the Astartes had paused in their advance to watch the descent of the three monstrously huge craft. Slowly dropping through the yellow skies in defiance of gravity like great primeval monoliths, the blackened hulks travelled on smoking pillars of fire as their colossal retros fought to slow them down. Even with such fiery deceleration, the ground shook with the hammerblow of their impacts, geysers of murky water thrown hundreds of metres into the air along with blinding clouds as the swamps flashed to steam. Massive hatches blew open and the motion resistant scaffolding fell away as the Titans of the Legio Mortis stepped from their landing craft and onto the moon's surface.

The Dies Irae led the Death's Head and Xestor's Sword, Warlord Titans with long, fluttering honour rolls hung from their armoured thorax. Each thunderous footstep of the mighty Titans sent Shockwaves through the swamps for kilometres in all directions, their bastion legs sinking several metres through the marshy ground to the bedrock beneath. Their steps churned huge gouts of mud and water, their appearance that of awesome gods of war come to smite the Warmaster's enemies beneath their mighty tread.

Loken watched the arrival of the Titans with a mixture of awe and unease: awe for the majesty of their colossal appearance, unease for the fact that the Warmaster felt it necessary to deploy such powerful engines of destruction.

The advance was slow going, trudging through clinging mud and stinking, brackish water, all the while unable to see much more than a few dozen metres. The thick fog banks deadened sound such that something close by might be inaudible while Loken could clearly hear the splash of warriors from Luc Sedirae's men, far to his right. Of course he couldn't see them through the yellow mist, so each company kept in regular vox contact to try and ensure they weren't separating.

Loken wasn't sure it was helping though. Strange groans and hisses, like the expelled breath of a corpse, bubbled from the ground and blurred shadow forms moved in the mist. Each time he raised his bolter to take aim in readiness, the mist would part and an armoured figure in the green of the Sons of Horus or the steel grey of the Word Bearers would be revealed. Erebus had led his warriors to Davin's moon in support of the Warmaster and Horus had welcomed their presence.

The mist gathered in thickness with unsettling speed, slowly swallowing them up until all Loken could see were warriors from his own company. They passed through a dark forest of leafless, dead trees, the bark glistening and wet looking. Loken paused to examine one, pressing his gauntlet against the tree's surface and grimacing as its bark sloughed off in wet chunks. Writhing maggots and burrowing creatures curled and wriggled within the rotten sapwood.

'These trees…' he said.

'What about them?' asked Vipus.

'I thought they were dead, but they're not.'

'No?'

'They're diseased. Rotten with it.'

Vipus shrugged and carried onwards, and once again Loken was struck by the certainty that something terrible had happened here. And looking at the diseased heart-wood of the tree, he wasn't sure that it was over. He wiped his stained gauntlet on his leg armour and set off after Vipus.

The eerily silent march continued through the fog and, assisted by the servo muscles of their armour, the Astartes quickly began to outpace the soldiers of the Imperial Army, who were finding the going much more difficult.

'Mournival,' said Loken over the inter-suit link. 'We need to slow our advance, we're leaving too big a gap between ourselves and the Army detachments.'

'Then they need to pick up the pace,' returned Abaddon. 'We don't have time to wait for lesser men. We're almost at the source of the vox.'

'Lesser men,' said Aximand. 'Be careful, Ezekyle, you're starting to sound a little like Eidolon now.'

'Eidolon? That fool would have come down here on his own to gain glory,' snarled Abaddon. 'I'll not be compared to him!'

'My apologies, Ezekyle. You're obviously nothing like him,' deadpanned Aximand.

Loken listened with amusement to his fellow Mournival's bantering, which, together with the quiet of Davin's moon began to reassure him that his concerns over their deployment here might be unfounded. He lifted his armoured boot from the swamp and took another step forward, this time feeling something crack under his step. Glancing down, he saw something round and greenish white bob upwards in the water.

Even without turning it over he could see it was a skull, the paleness of bone wreathed in necrotic strands of rotted flesh and muscle. A pair of shoulders rose from the depths behind it, the spinal column exposed beneath a layer of bloated green flesh.

Loken's lip curled in disgust as the decomposed corpse rolled onto its back, its sightless eye sockets filled with mud and weeds. Even as he saw the rotted cadaver, more bobbed to the surface, no doubt disturbed from their resting places on the bottom of the swamps by the footfalls of the Titans.

He called a halt and opened the link to his fellow commanders once again as yet more bodies, hundreds now, floated to the surface of the swamp. Grey and lifeless meat still clung to their bones and the imparts of the Titans' footfalls gave their dead limbs a horrid animation.

'This is Loken,' he said. 'I've found some bodies.'

'Are they Temba's men?' asked Horus.

'I can't tell, sir,' answered Loken. 'They're too badly decomposed. It's hard to tell. I'm checking now.'

He slung his bolter and leaned forwards, gripping the nearest corpse and lifting it from the water. Its bloated, rancid flesh was alive with wriggling motion, burrowing carrion insects and larvae nesting within it. Sure enough, mouldering scraps of a uniform hung from it and Loken wiped a smear of mud from its shoulder.

Barely legible beneath the scum and filth of the swamps he found a sewn patch bearing the number sixty-three emblazoned over the outline of a snarling wolfs head.

'Yes, 63rd Expedition,' confirmed Loken. 'They're Temba's, but I—'

Loken never finished the sentence as the bloated body suddenly reached up and fastened its bony fingers around his neck, its eyes filled with lambent green fire.

'Loken?' said Horus as the link was suddenly cut off. 'Loken?'

'Something amiss?' asked Torgaddon.

'I don't know yet, Tarik,' answered the Warmaster.

Suddenly the hard bangs of bolter fire and the whoosh of flame units could be heard from all around them.

'Second Company!' shouted Torgaddon. 'Stand to, weapons free!'

'Where's it coming from?' bellowed Horus.

'Can't say,' replied Torgaddon. 'The mist's playing merry hell with the acoustics.'

'Find out,' ordered the Warmaster.

Torgaddon nodded, demanding contact reports from all companies. Garbled shouts of impossible things came over the link, along with the louder bark of heavy bolter fire.

Gunfire sounded to his left and he spun to face it, his bolter raised before him. He could see nothing but the staccato flashes of weapon fire and the occasional blue streak of a plasma shot. Even the external senses of his armour were unable to penetrate the creeping mist.

'Sir, I think we—'

Without warning the swamp exploded as something vast and bloated erupted from the water before him. Its gangrenous, rotten flesh barrelled into him, its bulk sufficient to knock him onto his back and into the swamp.

Before he went under the dark water, Torgaddon had the fleeting impression of a yawning mouth filled with hundreds of fangs and a glaucous, cyclopean eye beneath a horn of yellowed bone.

'I don't know. The command net just went crazy,' said Moderati Primus Aruken in response to Princeps Turner's question. The external surveyors had suddenly and shockingly filled with returns that hadn't been there a second ago and his princeps had demanded to know what was going on.

'Well find out, damn you!' ordered Tumet. 'The Warmaster's out there.'

'Main guns spooled up and ready to fire,' reported Moderati Primus Titus Cassar.

'We need a damn target first, I'm not about to fire into that mess without knowing what I'm shooting at,' said Turnet. 'If it was Army I'd risk it, but not Astartes.'

The bridge of the Dies Irae was bathed in a red light, its three command officers seated upon their control seats on a raised dais before the green glow of the tactical plot. Wired into the very essence of the Titan, they could feel its every motion as though it were their own.

Despite the mighty war machine beneath him, Jonah Aruken suddenly felt powerless as this unknown enemy arose to engulf the Sons of Horus. Expecting armoured opposition and an enemy they could see, they had been little more than a focus for the Imperial forces to rally around so far. For all the Titan's overwhelming superiority in firepower, there was little they could do to aid their fellows.

'Getting something,' reported Cassar. 'Incoming signal.'

'What is it? I need better information than that, damn you,' shouted Turnet.

'Aerial contact. Signal's firming up. Fast moving and heading towards us.'

'Is it a Stormbird?'

'No, sir. All Stormbirds are accounted for in the deployment zone and I'm not picking up any military transponder signals.'

Turnet nodded. 'Then it's hostile. Do you have a solution, Aruken?'

'Running it now, princeps.'

'Range six hundred metres and closing,' said Cassar. 'God-Emperor protect us, it's coming right for us.'

'Aruken! That's too damn close, shoot it down.'

'Working on it, sir.'

'Work faster!'

The dense mists made looking through the frontal windshield pointless; nevertheless, there was an irresistible fascination in looking out at an alien world - not that there was much, or indeed anything, to see. Thus, Petronella's first impressions upon breaching the upper atmosphere were of disappointment, having expected exotic vistas of unimaginable alien strangeness.

Instead, they had been buffeted by violent storm winds and could see nothing but the yellow skies and banks of fog that seemed to be gathered around another unremarkable patch of brown swampland ahead.

Though the Warmaster had politely, but firmly, declined her request to travel to the surface with the warriors of the speartip, she had been sure there was a glint of mischief in his eye. Taking that for a sign of tacit approval, she had immediately gathered Maggard and her flight crew in the shuttle bay in preparation for descent to the moon below. Her gold-skinned landing skiff launched in the wake of the Army dropships, losing itself in the mass of assault craft heading to the moon's surface. Unable to keep pace with the invasion force, they had been forced to follow the emission trails and now found themselves circling deep in a soup of impenetrable fog that rendered the ground below virtually invisible.

'Getting some returns from up ahead, my lady,' said the first officer. 'I think it's the speartip.'

'At last,' she said. 'Get as close as you can then set us down. I want to get out of this mist so I can see something worth writing about.

'Yes, ma'am.'

Petronella settled back into her seat as the skiff angled its course towards the source of the surveyor return, irritably altering the position of her restraint harness to try to avoid creasing the folds of her dress. She gave up, deciding that the dress was beyond saving, and returned her gaze to the windshield as the pilot gave a sudden yell of terror.

Hot fear seethed in her veins as the mist before them cleared and she saw a huge mechanical giant before them, its proportions massive and armoured. Saw-toothed bastions and towers filled her vision, massive cannons and a terrible, snarling face of dark iron.

'Throne!' cried the pilot, hauling on the controls in a desperate evasive manoeuvre as roaring fire and light horrifyingly filled the windshield.

Petronella's world exploded in pain and broken glass as the guns of the Dies Irae opened fire and blasted her skiff from the yellow skies.

Loken surged backwards in horror and disgust as the cadaver attempted to strangle the life from him with its slimy fingers. For something as apparently fragile as a rotted corpse, the thing was possessed of a fearsome strength and he was dragged to his knees by the weight and power of the creature.

With a thought, he flooded his metabolism with battle stimms and fresh strength surged into his limbs. He gripped the arms of his attacker and pulled them from its reeking torso in a flood of dead fluids and a wash of brackish blood. The fire died in the thing's eyes and it flopped lifeless to the swamp.

He pushed himself to his feet and took stock of the situation, his Astartes training suppressing any notion of panic or disorientation. From all around them, the bodies he had previously thought to be lifeless were rising from the dark waters and launching themselves at his warriors.

Bolters blasted chunks of mouldered flesh from their bodies or tore limbs from putrefied torsos, but still they kept coming, tearing at the Astartes with diseased, yellowed claws. More of the things were rising all around them and Loken shot three down with as many shots, shattering skulls and exploding chests with mass-reactive shells.

'Sons of Horus, on me!' he yelled. 'Form on me.'

The warriors of 10th Company calmly began falling back to their captain, firing as they went at the necrotic horrors rising from the swamp like creatures from their worst nightmares. Hundreds of dead dungs surrounded them, mouldering corpses and bloated, muttering abominations, each with a single milky, distended eye and a scabrous horn sprouting from its forehead.

What were they? Monstrous xeno creatures with the power to reanimate dead flesh or something far worse? Thick, buzzing clouds of flies flew round them, and Loken saw an Astartes go down, the feeds on his helmet thick with fat bodied insects. The warrior frenziedly tore his helmet off and Loken was horrified to see his flesh rotting away with an unnatural rapidity, his skin greying and peeling away to reveal the liquefying tissue beneath.

The bark of bolter fire focussed him and he returned his attention to the battle before him, emptying magazine after magazine into the shambling mass of repulsive creatures before him.

'Head shots only!' he cried as he put another of the dead things down, its skull a ruin of blackened bone and sloshing ooze. The tide of the battle began to turn as more and more of the shambling horrors went down and stayed down. The green-fleshed things with grotesquely distended bellies took more killing, though it seemed to Loken that they dissolved into stinking matter as they fell into the water of the swamp.

More shapes moved through the mist as a thunderous roar of heavy cannon fire came from behind them, followed by the bright flare of an explosion high above. Loken looked up to see a golden landing skiff trailing smoke and fire wobble in the sky, though he had not the time to wonder what a civilian craft was doing in a warzone as yet more of the dead things climbed from the water.

Too close for bolters, he drew his sword and brought the monstrously toothed blade to life with a press of the activation stud. A ghastly thing of decomposed flesh and rotten meat hurled itself at him and he swung his blade two handed for its skull.

The blade roared as it slew, gobbets of wet, grey meat spattering his armour as he ripped the sword through from brainpan to groin. He swung at another creature, the green fire of its eyes flickering out as he hacked it in two. All about him, Sons of Horus went toe to toe with the terrible creatures that had once been members of the 63rd Expedition.

Rotted hands clamped onto his armour from beneath the water and Loken felt himself being dragged down. He roared and reversed his grip on his sword, stabbing it straight down into leering skulls and rotted faces, but incredibly their strength was the greater and he could not resist their pull.

'Garvi!' shouted Vipus, hacking enemies from his path as he forged through the swamp towards him.

'Luc! Help me!' cried Vipus, grabbing onto Loken's outstretched arm. Loken gripped onto his friend's hand as he felt another set of hands grip him around his chest and haul backwards.

'Let go, you bastards!' roared Luc Sedirae, hauling with all his might.

Loken felt himself rising and kicked out as the swamp creatures finally released him. He scrambled back and clambered to his feet. Together, he, Luc and Nero fought with bludgeoning ferocity, although there was no shape to the battle now, if there ever had been. It was nothing more than butcher work, requiring no swordsmanship or finesse, just brute strength and a determination not to fall. Bizarrely, Loken thought of Lucius, the swordsman of the Emperor's Children Legion, and of how he would have hated this inelegant form of war.

Loken returned his attention to the battle and, with Luc Sedirae and Nero Vipus in the fight, he was able to gain some space and time to reorganise.

'Thanks, Luc, Nero. I owe you,' he said in a lull in the fighting. The Sons of Horus reloaded bolters and cleaned chunks of dead flesh from their swords. Sporadic bursts of gunfire still sounded from the swamp and strobing flashes lit the fog with firefly bursts. Off to their left Loken saw a burning pyre where the skiff had come down, its flames acting as a beacon in the midst of the obscuring fog.

'No problem, Garvi,' said Sedirae, and Loken knew that he was grinning beneath his helmet. 'You'll do the same for me before we're out of this shit-storm, I'll wager.'

'You're probably right, but let's hope not.'

'What's the plan, Garvi?' asked Vipus.

Loken held up his hand for silence as he attempted to make contact with his Mournival brothers and the Warmaster once more. Static and desperate cries filled the vox, terrified voices of army soldiers and the damned, gurgling voices that kept saying, 'Blessed be Nurghleth…' over and over.

Then a voice cut across every channel and Loken almost cried aloud in relief to hear it.

'All Sons of Horus, this is the Warmaster. Converge on this signal. Head for the flames!'

At the sound of the Warmaster's voice, fresh energy filled the tired limbs and hearts of the Astartes, and they moved off in good order towards the burning pillar of fire coming from the wrecked skiff they had seen earlier. Loken killed with a methodical precision, each shot felling an opponent. He began to feel that they finally had the measure of this grotesque enemy.

Whatever fell energy bestowed animation upon these diseased nightmares was clearly incapable of giving them much more than basic motor functions and an unremitting hostility.

Loken's armour was covered in deep gouges and he wished he knew how many men he had lost to the loathsome hunger of the dead things.

He vowed that this Nurghleth would pay dearly for each of their deaths.

She could barely breathe, her chest hiking as she drew in convulsive gulps of air from the respirator Maggard was pushing against her face. Petronella's eyes stung, tears of pain coursing down her cheeks as she tried to push herself into a sitting position.

All she remembered was a fury of noise and light, a metallic shriek and a bone jarring impart as the skiff crashed and broke into pieces. Blood filled her senses and she felt excruciating pain all down her left side. Flames leapt around her, and her vision blurred with the sting of the atmosphere and smoke.

'What happened?' she managed, her voice muffled through the respirator's mouthpiece.

Maggard didn't answer, but then she remembered that he couldn't and twisted her head around to gain a better appreciation of their current situation. Torn up bodies clothed in her livery littered the ground - the pilots and flight crew of her skiff - and there was a lot of blood covering the wreckage. Even through the respirator, she could smell the gore.

Cloying banks of leprous fog surrounded them, though the heat of the flames appeared to be clearing it in their immediate vicinity. Shambling shapes surrounded them and relief flooded her as she realised that they would soon be rescued.

Maggard spun, drawing his sword and pistol, and Petronella tried to shout at him that he must stand down, that these were their rescuers.

Then the first shape emerged from the smoke and she screamed as she saw its diseased flesh and the rotted innards hanging from its opened belly. Nor was it the worst of the approaching things. A cavalcade of cadavers with bloated, ruptured flesh and putrid, diseased bodies sloshed through the mud and wreckage towards them, clawed hands outstretched.

The green fire in their eyes spoke of monstrous appetites and Petronella felt a gut-wrenching terror greater than anything she had ever known.

Only Maggard stood between her and the walking, diseased corpses, and he was but one man. She had watched him train in the gymnasia of Kairos many times, but she had never seen him draw his weapons in anger.

Maggard's pistol barked and each shot blasted one of the shambling horrors from its feet, neat holes drilled in its forehead. He fired and fired until his pistol was empty, and then holstered it and drew a long, triangular bladed dagger.

As the horde approached, her bodyguard attacked.

He leapt, feet first, at the nearest corpse and a neck snapped beneath his boot heel. Maggard spun as he landed, his sword decapitating a pair of the monsters, and his dagger ripping the throat from another. His Kirlian rapier darted like a silver snake, its glowing edge stabbing and cutting with incredible speed. Whatever it touched dropped instantly to the muddy ground like a servitor with its dotrina wafer pulled.

His body was always in motion, leaping, twisting and dodging away from the clutching hands of his diseased attackers. There was no pattern to their assault, simply a mindless host of dead things seeking to envelop them. Maggard fought like nothing she had ever seen, his augmetic muscles bulging and flexing as he cut down his foes with quick, lethal strokes.

No matter how many he killed, there were always more pressing in and they steadily forced him back a step at a time. The horde of creatures began to surround them, and Petronella saw that Maggard couldn't possibly hold them all back. He staggered towards her, bleeding from a score of minor wounds. His flesh was blistered and weeping around the cuts and there was an unhealthy pallor to his skin, despite his respirator gear.

She wept bitter tears of horror as the monsters closed in, jaws opening wide to devour her flesh, and grasping hands ready to tear her perfect skin and feast on her innards. This wasn't how it was supposed to be. The Great Crusade wasn't supposed to end in failure and death!

A corpse with mouldering, sagging skin lurched past Maggard, his blade lodged in the belly of a giant, necrotic thing with green flesh that was thick with flies.

She screamed as it reached for her.

Deafening bangs thundered behind her and the creature disintegrated in an explosion of wet meat and bone. Petronella covered her ears as the thunderous roar of gunfire came again and her attackers were torn apart in a series of rancid explosions, falling back into the fires of the skiff and burning with stinking green flames.

She rolled onto her side, crying in pain and fear as the terrifyingly close volleys continued, clearing a path for the massive, armoured warriors of the Sons of Horus.

A giant towered above her, reaching for her with his armoured gauntlet.

He wore no helmet and was silhouetted by a terrible red glow, his awesome bulk haloed by blazing plumes of fire and pillars of black smoke. Even through her tears, the Warmaster's beauty and physical perfection rendered her speechless. Though blood and dark slime covered his armour and his cloak was torn and tattered, Horus towered like a war god unleashed, his face a mask of terrifying power.

He lifted her to her feet as easily as one might lift a babe in arms, while his warriors continued the slaughter of the monstrous dead things. More and more Sons of Horus were converging on the crash site, guns firing to drive the enemy back and forming a protective cordon around the Warmaster.

'Miss Vivar,' demanded Horus. 'What in the name of Terra are you doing here? I ordered you to stay aboard the Vengeful Spirit!

She straggled for words, still in awe of his magnificent presence. He had saved her. The Warmaster had personally saved her and she wept to know his touch.

'I had to come. I had to see - '

'Your curiosity almost got you killed,' raged Horus. 'If your bodyguard had been less capable, you'd already be dead.'

She nodded dumbly, holding onto a twisted spar of metal to keep from collapsing as the Warmaster stepped through the debris towards Maggard. The gold armoured warrior held himself erect, despite the pain of his wounds.

Horus lifted Maggard's sword arm, examining the warrior's blade.

'What's your name, warrior?' asked the Warmaster.

Maggard, of course, did not answer, looking over at Petronella for help in answering.

'He cannot answer you, my lord,' said Petronella.

'Why not? Doesn't he speak Imperial Gothic?'

'He does not speak at all, sir. House Carpinus chaperones removed his vocal chords.'

'Why would they do that?'

'He is an indentured servant of House Carpinus and it is not a bodyguard's place to speak in the presence of his mistress.'

Horus frowned, as though he did not approve of such things, and said, 'Then you tell me what his name is.'

'He is called Maggard, sir.'

'And this blade he wields? How is it that the slightest touch of its edge slays one of these creatures?'

'It is a Kirlian blade, forged on ancient Terra and said to be able to sever the connection between the soul and the body, though I have never seen it used before today.'

'Whatever it is, I think it saved your life. Miss Vivar.'

She nodded as the Warmaster turned to face Maggard once more and made the sign of the aquila before saying, 'You fought with great courage, Maggard. Be proud of what you did here today.'

Maggard nodded and dropped to his knees with his head bowed, tears streaming from his eyes at being so honoured by the Warmaster.

Horus bent down and placed the palm of his hand on the bodyguard's shoulder, saying, 'Rise, Maggard. You have proven yourself to be a warrior, and no warrior of such courage should kneel before me.'

Maggard stood, smoothly reversing the grip of his sword and offering it, hilt first, to the Warmaster.

The yellow sky reflected coldly in his golden eyes, and Petronella shivered as she saw a newfound devotion in her bodyguard's posture, an expression of faith and pride that frightened her with its intensity.

The meaning of the gesture was clear. It said what Maggard himself could not.

I am yours to command.

Thus assembled, the Astartes took stock of their situation. All four phalanxes had rendezvoused around the crash site as the attacks from the diseased and dead things ceased for the time being. The speartip was blunted, but it was still an awesome fighting force and easily capable of destroying what remained of Temba's paltry detachment.

Sedirae volunteered his men to secure the perimeters, and Loken simply waved his assent, knowing that Luc was hungry for more battle and for a chance to shine in front of the Warmaster. Vipus re-formed the scouting parties and Verulam Moy set up fire positions for his Devastators.

Loken was relieved beyond words to see that all four members of the Mournival had survived the fighting, though Torgaddon and Abaddon had both lost their helmets in the furious melees. Aximand's armour had been torn open across his side and a splash of red, shockingly bright against the green of his armour, stained his thigh.

'Are you all right?' Torgaddon asked him, his armour stained and blistered, as though someone had poured acid over its plates.

'Just about,' nodded Loken. 'You?'

'Yes, though it was a close run thing,' conceded Torgaddon. 'Bastard got me underwater and was choking the life out of me. Tore my helmet right off and I think I must have drunk about a bucket of that swamp water. Had to gut him with my combat knife. Messy.'

Torgaddon's genhanced body would be unharmed by swallowing the water, no matter what toxins it carried, but it was a stark reminder of the power of these creatures that a warrior as fearsome as him could almost be overcome. Abaddon and Aximand had similar tales of close run things, and Loken desperately wanted the fight to be over. The longer the mission went on, the more it reminded him of Eidolon's abortive first strike on Murder.

Restored communications revealed that the Byzant Janizars had suffered terribly under the assault from the swamp and had hunkered down in defensive positions. Not even the electro-scythes of their discipline masters were able to coerce them forward. The horrific enemy had melted back into the fog, but no one could say with any certainty where the creatures had gone.

The Titans of the Legio Mortis towered over the Astartes, the Dies Irae reassuring the assembled warriors by the simple virtue of is immensity.

It was left to Erebus to point the way onwards, he and his depleted warriors staggering into the circle of light surrounding Petronella Vivar's crashed skiff. The first chaplain's armour was stained and battered, its many seals and scripture papers torn from it.

'Warmaster, I believe we have found the source of the transmissions,' reported Erebus. 'There is a… structure up ahead.'

'Where is it and how close?' demanded the Warmaster.

'Perhaps another kilometre to the west.'

Horus raised his sword and shouted, 'Sons of Horus, we have been grossly wronged here and some of our brothers are dead. It is time we avenge them.'

His voice easily carried over the dead waters of the swamps, his warriors roaring their assent and following the Warmaster, as Erebus and the Word Bearers set of into the mists.

Fired with furious energy, the Astartes ploughed through the sodden ground, ready to enact the Warmaster's wrath upon the vile foe that had unleashed such horrors upon them. Maggard and Petronella went with them, none of the Astartes willing to retreat and escort them back to the Army positions. Legion apothecaries tended their wounds and helped them through the worst of the terrain.

Eventually, the mists began to thin and Loken could make out the more distant figures of Astartes warriors through the smudges of fog. The further they marched, the more solid the ground underfoot became, and as Erebus led them onwards, the mist became thinner still.

Then, as quickly as a man might step from one room to another, they were out of it.

Behind them, the banks of fog gathered and coiled, like a theatre curtain in a playhouse waiting to unveil some wondrous marvel.

Before them was the source of the vox transmission, rearing up from the muddy plain like a colossal iron mountain.

Eugan Temba's flagship, the Glory of Terra.

SEVEN Watch our backs Collapse The betrayer

Rusted and dead nearly six decades, the vessel lay smashed and ruined on the cratered mudflats, its once mighty hull torn open and buckled almost beyond recognition. Its towering gothic spires, like the precincts of a mighty city, lay fallen and twisted, its buttresses and archways hung with decaying fronds of huge web-like vines. Its keel was broken, as though it had struck the moon's surface, belly first, and many of the upper surfaces had caved in, the decks below open to the elements.

Swathes of mossy greenery covered the hull and her command spire speared into the sky, warp vanes and tall vox masts bending in the moaning wind.

Loken thought the scene unbearably sad. That this should be the final resting place of such a magnificent vessel seemed utterly wrong to him.

Pieces of debris spotted the landscape, twisted hunks of rusted metal and incongruous personal items that must have belonged to the ship's crew and had been ejected during the massive impact with the ground.

'Throne…' breathed Abaddon.

'How?' was all Aximand could manage.

'It's the Glory of Terra alright,' said Erebus. 'I recognise the warp array configuration of the command deck. It's Temba's flagship.'

'Then Temba's already dead,' said Abaddon in frustration. 'Nothing could have survived that crash.'

'Then who's broadcasting that signal?' asked Horus.

'It could have been automated,' suggested Torgaddon. 'Maybe it's been going for years.'

Loken shook his head. 'No, the signal only started once we breached the atmosphere. Someone here activated it when they knew we were coming.'

The Warmaster stared at the massive shape of the wrecked spaceship, as if by staring hard enough he could penetrate its hull and discern what lay within.

'Then we should go in,' urged Erebus. 'Find whoever is inside and kill them.'

Loken rounded on the first chaplain. 'Go inside? Are you mad? We don't have any idea what might be waiting for us. There could be thousands more of those… things inside, or something even worse.'

'What is the matter, Loken?' snarled Erebus. 'Are the Sons of Horus now afraid of the dark?'

Loken took a step towards Erebus and said, 'You dare insult us, Word Bearer?'

Erebus stepped to meet Loken's challenge, but the Mournival took up position behind their newest member and their presence gave the first chaplain pause. Instead of pursuing the matter, Erebus bowed his head and said, 'I apologise if I spoke out of turn, Captain Loken. I sought only to erase the gross stain on the Legion's honour.'

'The Legion's honour is our own to uphold, Erebus,' said Loken. 'It is not for you to tell us how we must act.'

Horus decided the matter before further harsh words could be exchanged. 'We're going in,' he said.

The rippling fog bank followed the Astartes as they advanced towards the crashed ship and the Titans of the Legio Mortis followed behind, their legs still wreathed in the mists. Loken kept his bolter at the ready, conscious of the sounds of splashing water behind them, though he told himself that they were just the normal sounds of this world - whatever that meant.

As they closed the gap, he drew level with the War-master and said, 'Sir, I know what you will say, but I would be remiss if I didn't speak up.'

'Speak up about what, Garviel?' asked Horus.

'About this. About you leading us into the unknown.'

'Haven't I been doing that for the last two centuries?' asked Horus. 'All the time we've been pushing out into space, hasn't it been to push back the unknown? That's what we're here for, Garviel, to render that which is unknown, known.'

Loken sensed the commander's superlative skills of misdirection at work and kept himself focused on the point. The Warmaster had an easy way of steering conversations away from issues he didn't want to talk about.

'Sir, do you value the Mournival as counsel?' asked Loken, taking a different tack.

Horus paused in his advance and turned to face Loken, his face serious. 'You heard what I told that remembrancer in the embarkation deck didn't you? I value your counsel above all things, Garviel. Why would you even ask such a question?'

'Because so often you simply use us as your war dogs, always baying for blood. Having us play a role, instead of allowing us to keep you true to your course.'

'Then say what you have to say, Garviel, and I swear I will listen,' promised Horus.

'With respect, sir, you should not be here leading this speartip and we should not be going into that vessel without proper reconnaissance. We have three of the Mechanicum's greatest war machines behind us. Can we not at least let them soften up the target first with their cannons?'

Horus chuckled. 'You have a thinker's head on you, my son, but wars are not won by thinkers, they are won by men of action. It has been too long since I wielded a blade and fought in such a battle - against abominations that seeknothing more than our utter destruction. I told you on Murder that had I felt I could not take to the field of battle again, I would have refused the position of Warmaster.'

'The Mournival would have done this thing for you, sir,' said Loken. 'We carry your honour now.'

'You think my shoulders so narrow that I cannot bear it alone?' asked Horus, and Loken was shocked to see genuine anger in his stare.

'No, sir, all I mean is that you don't need to bear it alone.'

Horus laughed and broke the tension. His anger quite forgotten, he said, 'You're right of course, my son, but my glory days are not over, for I have many laurels yet to earn.'

The Warmaster set off once more. 'Mark my words, Garviel Loken, everything achieved thus far in this Crusade will pale into insignificance compared to what I am yet to do.'

Despite the Warmaster's insistence on leading the Astartes into the wreck, he consented to Loken's plan of allowing the Titans of the Legio Mortis to engage the target first. All three mighty war engines braced themselves and, at a command from the Warmaster, unleashed a rippling salvo of missiles and cannon fire into the massive ship. Flaring blooms of light and smoke rippled across the ship's immensity and it shuddered with each concussive impact. Fires caught throughout its hull, and thick plumes of acrid black smoke twisted skyward like signal beacons, as though the ship were trying to send a message to its former masters.

Once again, the Warmaster led from the front, the mist following mem in like a smoggy cape of yellow. Loken could still hear noises from behind them, but with the thunderous footfalls of the Titans, the crackling of the burning ship and their own splashing steps, it was impossible to be sure what he was hearing.

'Feels like a damned noose,' said Torgaddon, looking over his shoulder and mirroring Loken's thoughts perfectly.

'I know what you mean.'

'I don't like the mought of going in there, I can tell you that.'

'You're not afraid are you?' asked Loken, only half joking.

'Don't be flippant, Garvi,' said Torgaddon. 'For once I think you're right. There's something not right about this.'

Loken saw genuine concern in his friend's face, unsettled at seeing the joker Torgaddon suddenly serious. For all his bluster and informality, Tarik had good instincts and they had saved Loken's life on more than one occasion.

'What's on your mind?' he asked.

'I think this is a trap,' said Torgaddon. 'We're being funnelled here and it feels like it's to get us inside that ship.'

'I said as much to the Warmaster.'

'And what did he say?'

'What do you think?'

'Ah,' nodded Torgaddon. 'Well, you didn't seriously expect to change the commander's mind did you?'

'I thought I might have given him pause, but it's as if he's not listening to us any more. Erebus has made the commander so angry at Temba, he won't even consider any other option than going in and killing him with his bare hands.'

'So what do we do?' asked Torgaddon, and once again, Loken was surprised.

'We watch our backs, my friend. We watch our backs.'

'Good plan,' said Torgaddon. 'I hadn't thought of that. And here I was all set to walk into a potential trap with my guard down.'

That was the Torgaddon that Loken knew and loved.

The rear quarter of the crashed Glory of Terra reared up before them, its command decks pitched upwards at an angle, blotting out the diseased sky. It enveloped them in its dark, cold shadow, and Loken saw that getting into the ship would not be difficult. The gunfire from the Titans had blasted huge tears in its hull, and piles of debris had spilled from inside, forming great ramps of buckled steel like the rocky slopes before the walls of a breached fortress.

The Warmaster called a halt and began issuing his orders.

'Captain Sedirae, you and your assaulters will form the vanguard.'

Loken could practically feel Luc's pride at such an honour.

'Captain Moy, you will accompany me. Your flame and melta units will be invaluable in case we need to quickly cleanse an area or breach bulkheads.'

Verulam Moy nodded, his quiet reserve more dignified than Luc's eagerness to impress the Warmaster with his ardour.

'What are your orders, Warmaster?' asked Erebus, his grey armoured Word Bearers at attention behind their first chaplain. 'We stand ready to serve.'

'Erebus, take your warriors over to the other side of the ship. Find a way in and then rendezvous with me in the middle. If that bastard Temba tries to run, I want him crushed between us.'

The first chaplain nodded his understanding and led his warriors off into the shadow of the mighty vessel. Then the Warmaster turned to the Mournival.

'Ezekyle, use the signal locator on my armour to form overlapping echelons around my left. Little Horus, take my right. Torgaddon and Loken, form the rear. Secure this area and our line of withdrawal. Understood?'

The Warmaster delivered the orders with his trademark efficiency, but Loken was aghast at being left to cover the rear of their advance. He could see that the others of the Mournival, especially Torgaddon, were similarly surprised. Was this the Warmaster's way of punishing him for daring to question his orders or for suggesting that he should not be leading the speartip? To be left behind?

'Understood?' repeated Horus and all four members of the Mournival nodded their assent.

'Then let's move out,' snarled the Warmaster. 'I have a traitor to kill.'

Luc Sedirae led the assaulters, the bulky back burners of their jump packs easily carrying them up towards the black tears in the side of the ship. As Loken expected, Luc was first inside, vanishing into the darkness with barely a pause. His warriors followed him and were soon lost to sight, as Abaddon and Aximand found other ways inside, clambering up the debris to reach the still smoking holes that the Titans had torn. Aximand gave him a quick shrug as he led his own squads upwards, and Loken watched them go, unable to believe that he would not be fighting alongside his brothers as they went into battle.

The Warmaster himself strode up the piled debris as easily as a man might ascend a gently sloping hill, Verulam Moy and his weapons specialists following in his wake.

Within moments, they were alone on the desolate mudflats, and Loken could sense the confusion in his warriors. They stood awkwardly, awaiting orders to send them into the fight, but he had none to give them.

Torgaddon saved him from his stupefaction, bellowing out commands and lighting a fire under the Astartes left behind. They spread out to form a cordon around their position, Nero Vipus's scouts taking up position at the edge of the mist, and Brakespur climbing up the slopes to guard the entrances to the Glory of Terra.

'Just what exactly did you say to the commander?' asked Torgaddon, squelching back through the mud towards him.

Loken cast his mind back to the words that had passed between himself and the Warmaster since they had set foot on Davin's moon, searching for some offence that he might have given. He could find nothing serious enough to warrant his and Torgaddon's exclusion from the battle against Temba.

'Nothing,' he said, 'just what I told you.'

'This doesn't make any sense,' said Torgaddon, attempting to wipe some mud from his face, but only serving to spread it further across his features. 'I mean, why leave us out of all the fun. I mean, come on, Moy?'

'Verulam's a competent officer,' said Loken.

'Competent?' scoffed Torgaddon. 'Don't get me wrong, Garvi, I love Verulam like a brother, but he's a file officer. You know it and I know it and while there's nothing wrong with that and Emperor knows we need good file officers, he's not the sort the Warmaster should have at his side at a time like this.'

Loken couldn't argue with Tarik's logic, having had the same reaction upon hearing the Warmaster's orders. 'I don't know what to tell you, Tarik. You're right, but the commander has given his orders and we are pledged to obey him.'

'Even when we know those orders make no sense?'

Loken had no answer to that.

The Warmaster and Verulam Moy led the van of the speartip through the dark and oppressive interior of the Glory of Terra, its arched passageways canted at unnatural angles and its bulkheads warped and rusted with decay. Brackish water dripped through sections open to the elements, and a reeking wind gusted through the creaking hallways like a cadaver's breath. Diseased streamers of black fungus and dangling fronds of rotted matter brushed against their heads and helmets, leaving slimy trails of sticky residue behind.

The perforated floors were treacherous and uneven, but the Astartes made good time, pushing ever upwards through the halls of putrefaction towards the command decks.

Regular, static-laced communication with Sedirae's vanguard informed them of his progress ahead of them, the ship apparently lifeless and deserted. Even though the vanguard was relatively close, Sedirae's voice was chopped with interference, every third word or so unintelligible.

The deeper into the ship they penettated, the worse it got.

'Ezekyle?' said the Warmaster, opening the vox-mic on his gorget. 'Progress report.'

Abaddon's voice was barely recognisable, as crackling pops and wet hissing overlaid it with meaningless babble.

'Moving… th… gh the lowe… rat… decks… keep… We have… flank… master.'

Horus tapped his gorget. 'Ezekyle? Damn it.'

The Warmaster turned to Verulam Moy and said, 'Try and raise Erebus,' before returning to his own attempts at communication. 'Little Horus, can you hear me?'

More static followed, uninterrupted save for a faint voice, '…ordnance deck… slow… shells. Making safe… but… make… gress.'

'Nothing from Erebus,' reported Moy, 'but he may be on the other side of the ship by now. If the interference we are getting between our own warriors is anything to go by, it is unlikely our armour links will be able to reach him.'

'Damn it,' repeated the Warmaster. 'Well, let's keep going.'

'Sir,' ventured Moy. 'Might I make a suggestion?'

'If it's that we turn back, forget it, Verulam. My honour and that of the Crusade has been impugned and I'll not have it said that I turned my back on it.'

'I know that, sir, but I believe Captain Loken is correct. We are taking a needless risk here.'

'Life is a risk, my friend. Every day we spend away from Terra is a risk. Every decision I make is a risk. We cannot avoid risk, my friend, for if we do, we achieve nothing. If the highest aim of a captain were to preserve his ship, he would keep it in port forever. You are a fine officer, Verulam, but you do not see heroic opportunities as I do.'

'But, sir,' protested Moy, 'we cannot maintain contact with our warriors and we have no idea what might be waiting for us in this ship. Forgive me if I speak out of turn, but delving into the unknown like this does not feel like heroism. It feels like guesswork.'

Horus leaned in close to Moy and said, 'Captain, you know as well as I do that the whole art of war consists of guessing what is on the other side of the hill.'

'I understand that, sir—' began Moy, but Horus was in no mood for interruptions.

'Ever since the Emperor appointed me in the role of Warmaster, people have been telling me what I can and cannot do, and I tell you I am sick and tired of it,' snapped Horus. 'If people don't like my opinions, then that's their problem. I am the Warmaster and I have made up my mind. We go on.'

A squealing shriek of static abruptly sliced through the darkness and Luc Sedirae's voice came over the armour link as clearly as if he stood next to them.

'Throne! They're here!' shouted Sedirae.

Then everything turned upside down.

Loken felt it through the soles of his boots as a tremendous rumbling that seemed to come from the very foundations of the moon. He turned in horror, hearing metal grind on metal with a deafening screech, and watching geysers of mud spout skyward as buried portions of the starship tore themselves free of the sucking mud. The upper sections of the vessel plummeted towards the ground and the entire ship began tipping over, the colossal rear section arcing downwards with a terrible inevitability.

'Everyone get clear!' bellowed Loken as the massive weight of metal gathered speed.

Astartes scattered from the falling wreck, and Loken felt its massive shadow like a shroud as his armour's senses shut out the roaring noise of the starship's collapse.

He looked back in time to see the wreckage slam into the ground with the force of an orbital strike, the superstructure crumpling under the impact of its own weight and hurling lakes of muddy water through the air. Loken was tossed like a leaf by the Shockwave, landing waist deep in a stagnant pool of greenish scum and disappearing beneath the surface.

Rolling to his knees, he saw tsunamis of mud rippling out from the vessel, and watched as dozens of his warriors were buried beneath the brownish sludge. The power of the wrecked starship's impact spread from the crater it had gouged in the mud. A brackish rain of muddy water drizzled down, smearing his helmet's visor and reducing visibility to no more than a few hundred metres.

Loken climbed to his feet, clearing the action of his bolter as he realised the Shockwave had dispersed the sulphurous fog that had been their constant companion since landing on this accursed moon.

'Sons of Horus, stand ready!' he shouted, seeing what lay beyond the fog.

Hundreds of the dead things marched relentlessly towards them.

Not even the armour of a primarch could withstand the impact of a falling starship, and Horus grunted as he pulled a twisted spar of jagged iron from his chest. Sticky blood coated his armour, the wound sealing almost as soon as he had withdrawn the metal. His genhanced body could easily withstand such trivial punishment, and despite the spinning fall through the decks of the ship, he remained perfectly orientated and in balance on the sloping deck.

He remembered the sound of tearing metal, the clang of metal on armour and the sharp crack of bones snapping as Astartes warriors were thrown around like children in a funhouse.

'Sons of Horus!' he shouted. 'Verulam!'

Only mocking echoes answered him, and he cursed as he realised he was alone. The vox mic on his gorget was shattered, brass wires hanging limply from the empty socket, and he angrily ripped them away.

Verulam Moy was nowhere to be seen, and his squad members were similarly scattered beyond sight. Quickly taking stock of his surroundings, Horus could see that he lay partially buried in metal debris on the armorium vestibule, its ceiling bulging and cracked. Icy water dripped in a cold rain, and he tipped his head back to let it pour over his face.

He was close to the bridge of the ship, assuming it hadn't sheared off on impact with the ground - for surely there could be no other explanation for what had happened. Horus hauled himself from beneath the wreckage and checked to make sure that he was still armed, finding his sword hilt protruding from the detritus of the vestibule.

Pulling the weapon clear, its golden blade caught what little light there was and shone as though an inner fire burned within its core. Forged by his brother, Ferrus Manus of the Tenth Legion, the Iron Hands, it had been a gift to commemorate Horus's investiture as Warmaster.

He smiled as he saw that the weapon remained as unblemished as the day Ferrus had held it out to him, the light of adoration in his steel grey eyes, and Horus had never been more thankful for his brother's skill at the forge's anvil.

The deck creaked beneath his weight, and he suddenly began to question the wisdom of leading this assault. Despite that, he still seethed with molten rage for Eugan Temba, a man whose character he had believed in, and whose betrayal cut his heart with searing knives.

What manner of a man could betray the oath of loyalty to the Imperium?

What manner of base cur would dare to betray him?

The deck shifted again, Horus easily compensating for the lurching motion. He used his free hand to haul himself up towards the gaping doorway that led to the warren of passageways that riddled a ship this size. Horus had set foot on the Glory of Terra only once before, nearly seventy years ago, but remembered its layout as though it had been yesterday. Beyond this doorway lay the upper gantries of the armorium and beyond that, the central spine of the ship that led through several defensive choke points to the bridge.

Horus grunted as he felt a sharp pain in his chest and realised that the iron spar must have torn through one of his lungs. Without hesitation, he switched his breathing pattern and carried on without pause, his eyesight easily piercing the darkness of the vessel's interior.

This close to the bridge, Horus could see the terrible changes wrought upon the ship, its walls coated in loathsome bacterial slime that ate at the metal like an acidic fungus. Dripping fronds of waving, leech-like organisms suckled at oozing pustules of greenish brown matter, and an unremitting stench of decay hung in the air.

Horus wondered what had happened to this ship. Had the tribes of the moon unleashed some kind of deadly plague on the crew? Were these the means that Erebus had spoken of?

He could taste that the air was thick with lethal bacterial filth and biological contaminants, though none were even close to virulent enough to trouble his incredible metabolism. With the golden light of his sword to illuminate the way, Horus negotiated a path around the gantry, listening out for any signs of his warriors. The occasional distant crack of gunfire or clang of metal told him that he wasn't completely alone, but the whereabouts of the battles was a mystery. The corrupted inner structure of the ship threw phantom echoes and faraway shouts all around him until he decided to ignore them and press on alone.

Horus passed through the armorium and into the star-ship's central spine, the deck warped and canted at an unnatural angle. Flickering glow-globes and sputtering power conduits sparked and lit the arched passageway with blue electrical fire. Broken doors clanged against their frames with the rocking motion of the ship, making a sound like funeral bells.

Ahead he could hear a low moaning and the shuffle of callused feet, the first sounds he could clearly identify. They came from beyond a wide hatchway, toothed blast doors juddering open and closed like the jaws of some monstrous beast. Crushed debris prevented the doors from closing completely, and Horus knew that whatever was making the noises stood between him and his ultimate destination.

Some trick of the diffuse, strobing light threw jittering shadows from the mouth of the hatchway, and flickering after-images danced on his retinas as though the light came from a pict projector running in slow motion.

As the hatchway rumbled closed once more, a clawed hand reached out and gripped the smeared metal. Long, dripping yellow talons sprouted from the hand, the flesh of the wasted arm maggot-ridden and leprous. Another hand pushed through and clamped onto the metal, wrenching open the blast doors with a strength that belied the frailness of the arms.

The sensation of fear was utterly alien to Horus, but when the horrifying source of the sounds was revealed, he was suddenly seized with the conviction that perhaps his captains had been right after all.

A shambling mob of rotten-fleshed famine victims appeared, their shuffling gaits carrying them forwards in a droning phalanx of corruption. A creeping sensation of hidden power pulsed from their hunger-wasted bodies and swollen bellies, and buzzing clouds of flies surrounded their cyclopean, horned heads. Sonorous doggerel spilled from bloated and split lips, though Horus could make no sense of the words. Green flesh hung from exposed bones, and although they moved with the leaden monotony of the dead things, Horus could see coiled strength in their limbs and a terrible hunger in each monster's cataracted eyeball.

The creatures were less than a dozen metres from him, but their images were blurred and wavering, as though tears misted his vision. He blinked rapidly to clear it, and saw their swords, rusted and dripped with contagion.

'Well you're a handsome bunch and no mistake,' said Horus, raising his sword and throwing himself forward.

His golden sword clove into the monsters like a fiery comet, each blow hacking down a dozen or more without effort. Spatters of diseased meat caked the walls, and the air was thick with the stench of faecal matter, as each monster exploded with rotten bangs of flesh at his every blow. Filthy claws tore at Horus, but his every limb was a weapon. His elbow smashed skulls from shoulders, his knees and feet shattered spines, and his sword struck his foes down as if they were the mindless automatons in the training cages.

Horus did not know what manner of creatures these were, but they had obviously never faced a being as mighty as a primarch. He pushed further up the centtal spine of the starship, hacking a path through hundreds of organ-draped beasts. Behind him lay the ruin of his passing, shredded meat that reeked of decay and pestilence. Before him lay scores more of the creatures, and the bridge of the Glory of Terra.

He lost track of time, the primal brutality of the fight capturing the entirety of his attention, his sword strikes mechanical and bludgeoning. Nothing could stand before him, and with each blow, the Warmaster drew closer to his goal. The corridor grew wider as he pushed through the heaving mass of Cyclopean monsters, the golden sheen of his sword and the flickering, uncertain lights of the corridor making it appear that his enemies were becoming less substantial.

His sword chopped through a distended belly, ripping it wide open in a gush of stinking fluids, but instead of bursting open, the meat of the creature simply vanished like greasy smoke in the wind. Horus took another step forwards, but instead of meeting his foes head on with brutal ferocity, the corridor was suddenly and inexplicably empty. He looked around, and where once there had been a host of diseased creatures bent on his death, now there were only the reeking remains of hacked up corpses.

Even they were dissolving like fat on a griddle, vanishing in hissing streamers of green smoke so dark it was almost black.

'Throne,' hissed Horus, revolted by the sickening sight of the liquefying meat, and finally recognising the taint within the ship for what it was - a charnel house of the warp: a spawning ground of the Immaterium.

Horus felt fresh resolve fill his limbs as he drew closer to the multiple blast doors that protected the bridge, more certain than ever that he must destroy Eugan Temba. He expected yet more legions of the warp-spawned things, but the way was eerily quiet, the silence punctuated only by the sounds of more gunfire (which he was now sure was coming from beyond the hull) and the patter of black water on his armour.

Horus made his way forward cautiously, brushing sparking cables from his path as, one by one, the sealed blast doors slowly rumbled open at his approach. The whole thing reeked of a trap, but nothing could deny him his vengeance now, and he pressed onwards.

Stepping onto the bridge of the Glory of Terra, Horus saw that its colonnaded immensity had been changed from a place of command to something else entirely. Mouldering banners hung from the highest reaches, with long dead corpses stitched into the torn fabric of each one. Even from here, Horus could see that they wore the lupine grey uniforms of the 63rd Expedition, and he wondered if these poor souls had stayed true to their oaths of loyalty.

'You will be avenged, my friends,' he whispered as he stepped further into the bridge.

The tiered workstations were smashed and broken, their inner workings ripped out and rewired in some bizarre new way, metres-thick bundles of coiled wire rising into the darkness of the arched ceiling.

Throbbing energy pulsed from the cables and Horus realised that he was looking at the source of the vox signal that had so perturbed Loken on the way in.

Indeed, he fancied he could still hear the words of that damned voice whispering on the air like a secret that would turn your tongue black were you to tell it.

Nurghleth, it hissed, over and over…

Then he realised that it wasn't some auditory echo from the ship's vox, but a whisper from a human throat.

Horus's eyes narrowed as he sought the source of the voice, his lip curling in revulsion as he saw the massively swollen figure of a man standing before the captain's throne. Little more than a heaving mass of corpulent flesh, a terrific stench of rank meat rose from his fleshy immensity.

Flying things with glossy black bodies infested every fold of his skin, and scraps of grey cloth were stuck to his green grey flesh, gold epaulettes glinting and silver frogging hanging limply over his massive belly.

One hand rested in the glutinous mess of an infected wound in his chest, while the other held a sword with a glitter-sheen like diamond.

Horus dropped to his knees in anger and sorrow as he saw the slumped corpse of an Astartes warrior sprawled before the decayed splendour of the bloated figure.

Verulam Moy, his neck obviously broken and his sightless eyes fixed upon the decaying corpses hanging from the banners.

Even before Horus lifted his gaze to Moy's killer, he knew who it would be: Eugan Temba…

The Betrayer.

EIGHT Fallen god

Loken could scarcely remember a fight where he and his warriors had expended all their ammunition. Each Astartes carried enough shells to sustain them for most types of engagement, since no shot was wasted and each target would normally fall to a single bolt.

The ammo hoppers were back at the drop site and there was no way they could get through to them. The Warmaster's resolute advance had seen to that.

Loken's full capacity of bolter rounds had long been expended, and he was thankful for Aximand's insistence on subsonic rounds, as they made satisfyingly lethal explosions within the bodies of the dead things.

'Throne, don't they ever stop?' gasped Torgaddon. 'I must have killed a hundred or more of the damned things.'

'You probably keep killing the same one,' replied Loken, shaking his sword free of grey matter. 'If you don't destroy the head, they get back up again. I've cut down half a dozen or more with bolter wounds in them.'

Torgaddon nodded and said, 'Hold on, the Legio's coming again.'

Loken gripped onto a more solid piece of debris, as the Titans began yet another deadly strafing run through the mass of rotted monsters. Like the monstrous giants said to haunt the mists of Barbarus, the Titans emerged from the fog with fists of thunder and fire. Wet explosions mushroomed from the swamp as high explosives hurled the cadavers into the air and the crashing steps of the mighty war machines crashed them to ooze beneath their hammer-blow footsteps.

The very air thrummed with the vibrations of the Titans' attack, avalanches of debris and mud sliding from the Glory of Terra with each explosion and titanic footstep. The dead things had gained the slopes of rubble and detritus that led into the starship three times; and three times had they sent them back, first with gunfire, and, when the ammunition had ran out, with blades and brute strength. Each time they killed hundreds of their enemies, but each time a handful of Astartes was dragged down and pulled beneath the waters of the swamp.

Under normal circumstances, the Astartes would have had no trouble in dealing with these abominations, but with the Warmaster's fate unknown they were brittle and on edge, unable to think or fight with their customary ferocity. Loken knew exactly what they were feeling, because he felt it too.

Unable to raise the Warmaster, Aximand or Abaddon, the warriors outside the hulk were left paralysed and in disarray without their beloved leader.

'Temba,' said the Warmaster, rising to his feet and marching towards his erstwhile planetary governor. With each step, he saw further evidence of Eugan Temba's treachery, clotted blood on the edge of his sword and a fierce grin of anticipation. Where once had been the loyal and upright follower, Horus now saw only a filthy traitor who deserved the most painful of deaths. A fell light grew around Temba, further revealing the corruption of his flesh, and Horus knew that nothing of his former friend was left in the diseased shell that stood before him.

Horus wondered if this was what Loken had experienced beneath the mountains of Sixty-Three Nineteen: the horror of a former comrade succumbing to the warp. Horus had known of the bad blood between Jubal and Loken, now understanding that such enmity, however trivial, had been the chink in Jubal's armour by which the warp had taken him.

What flaw had been Temba's undoing? Pride, ambition, jealousy?

The bloated monster that had once been Eugan Temba looked up from the corpse of Verulam Moy and smiled, thoroughly pleased with its work.

'Warmaster,' said Temba, each syllable glottal and wet, as though spoken through water.

'Do not dare to address me by such a tide, abomination.'

'Abomination?' hissed Temba, shaking his head. 'Don't you recognise me?'

'No,' said Horus. 'You're not Temba, you're warp-spawned filth, and I'm here to kill you.'

'You are wrong, Warmaster,' it laughed. 'I am Temba. The so-called friend you left behind. I am Temba, the loyal follower of Horus you left to rot on this backwater world while you went on to glory.'

Horus approached the dais of the captain's throne and dragged his eyes from Temba to the body of Verulam Moy. Blood streamed from a terrible wound in his side, pumping energetically onto the stained floor of the bridge. The flesh of his throat was purple and black, a lump of broken bone pushing at the bruised skin where his neck had been snapped.

'A pity about Moy,' said Temba. 'He would have been a fine convert.'

'Don't say his name,' warned Horus. 'You are not fit to give it voice.'

'If it consoles you, he was loyal until the end. I offered him a place at my side, with the power of Nurghleth filling his veins with its immortal necrosis, but he refused. He felt the need to try to kill me, foolish really. The power of the warp fills me and he had no chance at all, but that didn't stop him. Admirable loyalty, even if it was misplaced.'

Horus placed a foot on the first step of the dais, his golden sword held out before him, his fury at this beast drowning out all other concerns. All he wanted to do was throttle the life from this treacherous bastard with his bare hands, but he retained enough sense to know that if Moy had been killed with such apparent ease, then he would be a fool to discard his weapon.

'We don't have to be enemies, Horus,' said Temba. 'You have no idea of the power of the warp, old friend. It is like nothing we ever saw before. It's beautiful really'

'It is power,' agreed Horus, climbing another step, 'elemental and uncontrollable and therefore not to be trusted.'

'Elemental? Perhaps, but it is far more than that,' said Temba. 'It seethes with life, with ambition and desire. You think it's a wasteland of raging energy that you bend to your will, but you have no idea of the power that lies there: the power to dominate, to control and to rule.'

'I have no desire for such things,' said Horus.

'You lie,' giggled Temba. 'I can see it in your eyes, old friend. Your ambition is a potent thing, Horus. Do not be afraid of it. Embrace it and we will not be enemies, we will be allies, embarking upon a course that will see us masters of the galaxy.'

'This galaxy already has a master, Temba. He is called the Emperor.'

'Then where is he? He blundered across the cosmos in the manner of the barbarian tribes of ancient Terra, destroying anyone who would not submit to his will, and then left you to pick up the pieces. What manner of leader is that? He is but a tyrant by another name.'

Horus took another step, and was almost at the top of the dais, almost within striking distance of this traitor who dared to profane the name of the Emperor.

'Think about it, Horus,' urged Temba. 'The whole history of the galaxy has been the gradual realisation that events do not happen in an arbitrary manner, but that they reflect an underlying destiny. That destiny is Chaos.'

'Chaos?'

'Yes!' shouted Temba. 'Say it again, my friend. Chaos is the first power in the universe and it will be the last. When the first ape creatures bashed each other's brains out with bones, or cried to the heavens in the death throes of plague, they fed and nurtured Chaos. The blissful release of excess and the glee of intrigue - all is grist for the soul mills of Chaos. So long as Man endures, so too does Chaos.'

Horus reached the top of the dais and stood face to face with Temba, a man he had once counted as his friend and comrade in this great undertaking. Though the thing spoke with Temba's voice and its stretched features were still those of his comrade, there was nothing left of that fine man, only this wretched creature of the warp.

'You have to die,' said Horus.

'No, for that is the glory of Nurghleth,' chuckled Temba. 'I will never die.'

'We'll soon see about that,' snarled Horus, and drove his sword into Temba's chest, the golden blade easily sliding through the layers of blubber towards the traitor's heart.

Horus ripped his sword free in a wash of black blood and stinking pus, the stench almost too much for even him to bear. Temba laughed, apparently untroubled by such a mortal wound, and brought up his own sword, its glinting, fractured blade like patterned obsidian.

He brought the blade to his blue lips and said, 'The Warmaster Horus.'

With a speed that was unnatural in its swiftness, the tip of the blade speared for the Warmaster's throat.

Horus threw up his sword, deflecting Temba's weapon barely a centimetre from his neck, and took a step backwards as the traitor lurched towards him. Recovering from the surprise attack, Horus gripped his sword two-handed, blocking every lethal thrust and cut that Temba made.

Horus fought like never before, his every move to parry and defend. Eugan Temba had never been a swordsman, so where this sudden, horrifying skill came from Horus had no idea. The two men traded blows back and forth across the command deck, the bloated form of Eugan Temba moving with a speed and dexterity quite beyond anything that should have been possible for someone of such vast bulk. Indeed, Horus had the distinct impression that it was not Temba's skill with a blade that he was up against, but the blade itself.

He ducked beneath a decapitating strike and spun inside Temba's guard, slashing his sword through his opponent's belly, a thick gruel of infected blood and fat spilling onto the deck. The dark blade darted out and struck his shoulder guard, ripping it from his armour in a flash of purple sparks.

Horus danced back from the blow as the return stroke arced towards his head. He dropped and rolled away as Temba turned his bloody, carven body back towards him. Any normal man would have died a dozen times or more, but Temba seemed untroubled by such killing wounds.

Temba's face shone with glistening sweat, and Horus blinked as the monster's outline wavered, like those of the cyclopean monsters that he had fought in the ship's central spine. Frantic motion shimmered and he could see something deep within the monstrously swollen body, the faint outline of a screaming man, his hands clasped to his ears and his face twisted in a rictus grin of horror.

Trailing his innards like gooey ropes, Eugan Temba descended the steps of the dais like a socialite making her entrance at one of the Merican balls. Horus saw the cursed sword gleaming with a terrible hunger, its edges twitching in Temba's hand, as though aching to bury itself in his flesh.

'It doesn't have to end this way, Horus,' gurgled Temba. 'We need not be enemies.'

'No,' said Horus. 'We do. You killed my friend and you betrayed the Emperor. It can be no other way.'

Even before the words were out of his mouth, the smoky grey blade streaked towards him, and Horus threw himself back as the razor-sharp edge grazed his breastplate and cut into the ceramite. Horus backed away from Temba, hearing twin cracks as the monstrously bloated traitor's anklebones finally snapped under his weight.

Horus watched as Temba dragged himself forwards unsteadily, the splintered ends of bone jutting from the bloody flesh of his ankles. No normal man could endure such agony, and Horus felt a flickering ember of compassion for his former friend stir within his breast. No man deserved to be abused so, and Horus vowed to end Temba's suffering, seeing again the jagged after-image sputtering within the alien flesh of the warp. 'I should have listened to you, Eugan,' he whispered. Temba didn't reply. The glimmering blade wove bright patterns in the air, but Horus ignored it, too seasoned a warrior to be caught by such an elementary trick.

Once again, Temba's blade reached out for him, but Horus was now gaining a measure of its hunger to do him harm. It attacked without thought or reason, only the simple lust to destroy. He looped his own blade around the quillons of Temba's sword and swept his arm out in a disarming move, before closing to deliver the deathblow.

Instead of releasing the blade for fear of a shattered wrist, however, Temba retained his grip on the sword, its tip twisting in the air and plunging towards Horus's shoulder.

Both blades pierced flesh at the same instant, Horus's tearing through his foe's chest and into his heart and lungs, as Temba's stabbed into the muscle of Horus's shoulder where his armour had been torn away.

Horus yelled in sudden pain, his arm burning with the shimmering sword's touch, and reacted with all the speed the Emperor had bred into him. His golden sword slashed out, severing Temba's arm just above the elbow and the sword clanged to the deck where it twitched in the grip of the severed arm with a loathsome life of its own.

Temba wavered and fell to his knees with a cry of agony, and Horus reared above his foe with his sword upraised. His shoulder ached and bled, but victory was now his and he roared with anger, as he stood ready to enact his vengeance.

Through the red mist of anger and hurt, he saw the pathetic, weeping and soiled form of Eugan Temba stripped of the loathsome power of the warp that had claimed him. Still bloated and massive, the dark light in his eyes was gone, replaced by tears and pain as the enormity of his betrayal crashed down upon him.

'What have I done?' asked Temba, his voice little more than a whisper.

The anger went out of Horus in an instant and he lowered his sword, kneeling beside the dying man that had once been his trusted friend.

Juddering sobs of agony and remorse wracked Temba's body and he reached up with his remaining hand to grip the Warmaster's armour.

'Forgive me, my friend,' he said. 'I didn't know. None of us did.'

'Hush now, Eugan,' soothed Horus. 'It was the warp. The tribes of the moon must have used it against you. They would have called it magic.'

'No… I'm so sorry,' wept Temba, his eyes dimming as death reached up to claim him. 'They showed us what it could do and I saw the power of it. I saw beyond and into the warp. I saw the powers that dwell there and, Emperor forgive me, I still said yes to it.'

'There are no powers that dwell there, Eugan,' said Horus. 'You were deceived.'

'No!' said Temba, gripping Horus's arm tightly. 'I was weak and I fell willingly, but it is done with me now. There is great evil in the warp and I need you to know the truth of Chaos before the galaxy is condemned to the fate that awaits it.'

'What are you talking about? What fate?'

'I saw it, Warmaster, the galaxy as a wasteland, the Emperor dead and mankind in bondage to a nightmarish hell of bureaucracy and superstition. All is grim darkness and all is war. Only you have the power to stop this future. You must be strong, Warmaster. Never forget that…'

Horus wanted to ask more, but watched impotently as the spark of life fled Eugan Temba.

His shoulder still burning with fire, Horus rose to his feet and marched over to the rewired consoles and die throbbing bundle of cables that reached up to the chamber's roof.

With an aching cry of loss and anger, he severed the cables with one mighty blow of his sword. They flopped and spun like landed fish, sparks and green fluids spurting from internal tubes and cables, and Horus could tell that the damnable vox transmission had ceased.

Horus dropped his sword and, clutching his injured shoulder, sat on the deck next to Eugan Temba's dead body and wept for his lost friend.

Loken hacked his sword through another corpse's neck, dropping the mouldering revenant to the ground as still more pressed in behind it. He and Torgaddon fought back to back, their swords coated in the flesh of the dead things as they were pushed further and further up the slopes of metal that led inside the starship. Their warriors fought desperately, each blow leaden and exhausted. The Titans of the Legio Mortis crushed what they could and sporadically raked the base of the rubble with sprays of gunfire, but there was no stopping the horde.

Dozens of Astartes were dead, and there was still no word from the forces that had entered the Glory of Terra. Garbled vox transmissions from the Byzant Janizars seemed to indicate that they were finally moving forward, but no one could be sure as to where exactly they were moving.

Loken fought with robotic movements, his every blow struck with mechanical regularity rather than skill. His armour was dented and torn in a dozen places, but still he fought for victory, despite the utter desperation of their cause.

That was what Astartes did: they triumphed over insurmountable odds. Loken had lost track of how long they had been fighting, the brutal sensations of this combat having dulled his senses to all but his next attacker.

'We'll have to pull back into the ship!' he shouted.

Torgaddon and Nero Vipus nodded, too busy with their own immediate situations to respond verbally, and Loken turned and began issuing orders across the inter-suit vox, receiving acknowledgements from all his surviving squad commanders.

He heard a cry of anger and, recognising it as belonging to Torgaddon, turned with his sword raised. A mob of stinking cadavers swamped the top of the slopes, overwhelming die Astartes gathered there in a frenzy of clawing hands and biting jaws. Torgaddon was borne to the ground, and the mouths of the corpses fastened on his neck and arms were dragging him down.

'No!' shouted Loken as he leapt towards the furious combat. He shoulder charged in amongst them, sending bodies flying down the slopes. His fists crushed skulls and his sword hacked dead things in two. A gauntleted fist thrust up through grey flesh and he grabbed it, feeling the weight of an armoured Astartes behind it.

'Hold on, Tarik!' he ordered, hauling on his friend's arm. Despite his strength, he couldn't free Torgaddon and felt grasping limbs envelop his legs and waist. He clubbed with his free hand, but he couldn't kill enough of them. Hands tore at his head, smearing blood across his visor and blinding him as he felt himself falling.

Loken thrashed in vain, breaking dead things apart, but unable to prevent himself and Torgaddon from being pulled apart. Claws tore at his armour, the unnatural strength of their enemies piercing his flesh and drawing his precious blood. A grinning, skull faced monster landed on his chest, face to face with him, and its jaws snapped shut on his visor. Unable to penetrate the armoured glass, rivulets of muddy saliva blurred his vision as its jaws worked up and down.

Loken head-butted the thing from his chest and rolled onto his front to gain some purchase. He lost his grip on his sword and bellowed in anger as he finally began to free himself from their intolerable grip. Loken fought with every ounce of his strength, finally gaining a respite and rising to his feet.

All around him, warriors of the Astartes struggled with the dead things, and he knew that they were undone.

Then, at a stroke, every one of the dead things dropped to the ground with a soft sigh of release.

Where seconds before the area around the starship had been a furious battlefield of warriors locked in life or death struggles, now it was an eerily silent graveyard. Bewildered Astartes picked themselves up and looked around at the inert, lifeless bodies surrounding them.

'What just happened?' asked Nero Vipus, disentangling himself from a pile of bludgeoned corpses. 'Why have they stopped?'

Loken shook his head. He had no answer to give him. 'I don't know, Nero.'

'It doesn't make any sense.'

'You'd rather they got back up?'

'No, don't be dense. I just mean that if someone was animating these things, then why stop now? They had us.'

Loken shuddered. For someone to wield a power that could defeat the Astartes was a sobering thought. All the time they had crusaded through the galaxy there had been nothing that could stand against them for long - eventually the enemy's will would break in the face of the overwhelming superiority of the Space Marines. Would this happen when they met a foe with a will as implacable as their own?

Shaking himself free of such gloomy thoughts, he began issuing orders to dispose of the dead things, and they began hurling them from the wreckage, hacking or tearing heads from shoulders lest they reanimate.

Eventually Aximand and Abaddon led their warriors from the wreckage, battered and bloody from the ship's fall, but otherwise unharmed. Erebus too returned, his Word Bearers similarly abused, but also largely unharmed.

There was still no sign of Sedirae's men or the Warmaster.

'We're going back in there for the Warmaster,' said Abaddon. 'I'll lead.'

Loken was about to protest, but nodded as he saw the unshakable resolve in Ezekyle's face.

'We'll all go,' he said.

They found Luc Sedirae and his men trapped in one of the lower decks, hemmed in by fallen bulkheads and tonnes of debris. It took the better part of an hour to move enough of it to grant Luc's assaulters their freedom. On pulling Sedirae from his prison, all he could say was, 'They were here. Monsters with one eye… came out of nowhere, but we killed them, all of them. Now they're gone.'

Luc had suffered casualties: seven of his men were dead and his perpetual grin was replaced by a vengeful expression that reminded Loken of a defiant young boy's. Black, stinking residue coated the walls, and Sedirae had a haunted look to him that Loken did not like at all. It reminded him of Euphrati Keeler in the moments after the warp thing that had taken Jubal almost killed her.

With Sedirae and his warriors in tow, the Mournival pressed on with Loken leading the way, finding signs of battle scattered throughout the ship, bolter impacts and sword cuts that led inexorably towards the ship's bridge.

'Loken,' whispered Aximand. 'I fear what we may find ahead. You should prepare yourself.'

'No,' said Loken. 'I know what you are suggesting, but I won't think of that. I can't.'

'We have to be prepared for the worst.'

'No,' said Loken, louder than he had intended. 'We would know if—'

'If what?' asked Torgaddon.

'If the Warmaster was dead,' said Loken finally.

Thick silence enveloped them as they struggled to come to terms with such a hideous idea.

'Loken's right,' said Abaddon. 'We would know if the Warmaster was dead. You know we would. You of all of us would feel it, Little Horus.'

'I hope you're right, Ezekyle.'

'Enough of this damned misery,' said Torgaddon. 'All this talk of death and we haven't found hide nor hair of the Warmaster yet. Save your gloomy thoughts for the dead that we already know about. Besides, we all know that if the Warmaster was dead, the sky would have fallen, eh?'

That lightened their mood a little and they pressed on, making their way along the central spine of the ship, passing through juddering bulkheads and along corridors with flickering lights, until they reached the blast doors that led to the bridge.

Loken and Abaddon led the way, with Aximand, Torgaddon and Sedirae bringing up the rear.

Inside it was almost dark, only a soft light from raptured consoles providing any illumination.

The Warmaster sat with his back to them, his glorious plate armour dented and filthy, cradling something vast and bloated in his lap.

Loken drew level with the Warmaster, grimacing as he saw a grotesquely swollen human head in his commander's lap. A great puncture wound pierced the Warmaster's breastplate and a bloody stab wound on his shoulder leaked blood down the armour of his arm.

'Sir?' said Loken. 'Are you alright?'

The Warmaster didn't answer, instead cradling the head of what Loken could only assume was Eugan Temba. His bulk was immense, and Loken wondered how such a monstrously fat creature could possibly have moved under his own strength.

The Mournival joined Loken, shocked and horrified at the Warmaster's appearance, and at this terrible place. They looked at one another with a growing unease, none quite knowing what to make of this bizarre scene.

'Sir?' said Aximand, kneeling before the weeping Warmaster.

'I failed him,' said Horus. 'I failed them all. I should have listened, but I didn't and now they're all dead. It's too much.'

'Sir, we're going to get you out of here. The dead things have stopped attacking. We don't know how long that's going to last, so we need to get out of this place and regroup.'

Horus shook his head slowly. 'They won't be attacking again. Temba's dead and I cut the vox signal. I don't know how exactly, but I think it was part of what was animating those poor souls.'

Abaddon pulled Loken aside and hissed, 'We need to get him out of here, and we can't let anyone see the state he's in.'

Loken knew that Abaddon was right. To see the Warmaster like this would break the spirit of every Astartes who saw him. The Warmaster was an invincible god of war, a towering figure of legend that could never be brought low.

To see him humbled so would be a blow to morale that the 63rd Expedition might never recover from.

Gently, they prised Eugan Temba's massive body away from the Warmaster and lifted their commander to his feet. Loken slung the Warmaster's arm over his shoulder, feeling a warm wetness against his face from the blood that still dripped from Horus's arm.

Between them, he and Abaddon walked the Warmaster from the bridge.

'Walk,' said the Warmaster, his voice weak and low. 'I'll walk out of this place on my own.'

Reluctantly, they let him go, and though he swayed a little, the Warmaster kept his feet, despite the ashen pallor of his face and the obvious pain he was in.

The Warmaster spared a last look at Eugan Temba and said, 'Gather up Verulam and let's get out of here, my sons.'

Maggard slumped against the steel bulkhead of the Glory of Terra, his sword covered in black fluids from the dead things. Petronella fought to hold back tears at the thought of how close they had all come to death on this bleak, Emperor forsaken moon.

Sheltered behind the bulkhead where Maggard had thrust her, she had heard rather than seen the desperate conflict that raged outside - the war cries, the sound of motorised blades tearing into wet meat, the percussive booms and explosive flashes of light from the Titans' weapons.

Her imagination filled in the blanks and though a gut-loosening terror filled her from head to toe, she pictured glorious combats and heroic duels between the towering Astartes giants and the corrupt foes that sought their destruction.

Her breathing came in short, convulsive gasps as she realised she had just survived her first battle, but with that realisation came a strange calm: her limbs stopped shaking and she wanted to smile and laugh. She wiped her hand across her eyes, smearing the kohl that lined them across her cheeks like tribal war paint.

Petronella looked over at Maggard, seeing him now for the great warrior he truly was, barbaric and bloody, and magnificent. She pushed herself to her feet and leaned out beyond her sheltering bulkhead to look at the battlefield below.

It was like a scene from one of Keland Roget's landscapes, and the sublime vision took her breath away. The fog and mist had lifted and the sun was already breaking through to bathe the landscape in its ruddy red glow. The pools of swamp water glittered like shards of broken glass spread across the landscape. The three magnificent Titans of the Legio Mortis watched over squads of Astartes, armed with flamers, putting the corpses of the dead things to the torch, and pyres of the fallen monsters burned with a blue green light.

She was already forming the metaphors and imagery she would use: the Emperor's warriors taking his light into the dark places of the galaxy, or perhaps that the Astartes were his Angels of Death bringing his retribution to the unrighteous.

The words had the right epic tone, but she sensed that such imagery still lacked some fundamental truth, sounding more like propaganda slogans than anything else.

This was what the Great Crusade was all about and the fear of the last few hours was washed away in a swelling wave of admiration for the Astartes and the men and women of the 63rd Expedition.

She turned as she heard heavy footfalls. The officers of the Mournival were marching towards her, a plate armoured body borne upon their shoulders, and the levity she had witnessed in them earlier now utterly absent. Each one's face, even the joker Torgaddon's, was serious and grim.

The cloaked figure of the Warmaster himself followed behind them, and she was shocked rigid at his beaten appearance. His armour was torn and gashed with foulness, and blood spatters matted his face and arm.

'What happened?' she asked as Captain Loken passed her. 'Whose body is that?'

'Be silent,' he snapped, 'and be gone.'

'No,' said the Warmaster. 'She is my documentarist and if that is to mean anything then she must see us at our worst as well as our best'

'Sir—' began Abaddon, but Horus cut him off. 'I'll not be argued with on this, Ezekyle. She comes with us.'

Petronella felt her heart leap at this inclusion and fell into step with the Warmaster's party as they began their descent to the ground.

'The body is that of Verulam Moy, captain of my 19th Company,' said Horus, his voice weary and filled with pain. 'He fell in the line of duty and will be honoured as such.'

'You have my deepest sorrows, my lord,' said Petronella, her heart aching to see the Warmaster in such pain.

'Was it Eugan Temba?' she asked, fishing out her data-slate and mnemo-quill. 'Did he kill Captain Moy?'

Horus nodded, too weary even to answer her.

'And Temba is dead? You killed him?'

'Eugan Temba is dead,' answered Horus. 'I think he died a long time ago. I don't know exactly what I killed in there, but it wasn't him.'

'I don't understand.'

'I'm not sure I do either,' said Horus, stumbling as he reached the bottom of the slope of debris. She reached out a hand to steady him, before realising what a ridiculous idea that was. Her hand came away bloody and wet, and she saw that the Warmaster still bled from a wound in his shoulder.

'I ended the life of Eugan Temba, but damn me if I didn't weep for him afterwards.'

'But wasn't he an enemy?'

'I have no trouble with my enemies, Miss Vivar,' said Horus. 'I can take care of my enemies in a fight. But my so-called allies, my damned allies, they're the ones who keep me walking the floors at night.'

Legion apothecaries made their way towards the Warmaster as she tried to make sense of what he was saying. She allowed the mnemo-quill to inscribe his words anyway. She saw the looks she was getting from the Mournival, but ignored them.

'Did you speak to him before you slew him? What did he say?'

'He said… that only I had the power… to stop the future…' said the Warmaster, his voice suddenly faint and echoing as though coming from the other end of a long tunnel.

Puzzled, she looked up in time to see the Warmaster's eyes roll back in their sockets and his legs buckle beneath him. She screamed, reaching out with her hand towards him, knowing that she was powerless to help him, but needing to try to prevent his fall.

Like a slow moving avalanche or a mountain toppling, the Warmaster collapsed.

The mnemo-quill scratched at the data-slate and she wept as she read the words there.

I was there the day that Horus fell.

NINE Silver towers A bloody return The veil grows thin

From here, he could see the pyramid roof of the Amenaeum, die low evening sun reflecting on its gold panels as if it were ablaze, and even though Magnus knew he used but a colourful metaphor, the very idea gave him a pang of loss. To imagine that vast repository of knowledge lost in the flames was abhorrent and he turned his Cyclopean gaze from the pyramid of crystal glass and gold.

Tizca, the so-called City of Light, stretched out before him, its marble colonnades and wide boulevards tree-lined and peaceful. Soaring towers of silver and gold reared above a city of gilded libraries, arched museums and sprawling seats of learning. The bulk of the city was constructed of white marble and gold-veined ouslite, shining like a bejewelled crown in the sun. Its architecture spoke of a time long passed, its buildings shaped by craftsmen who had honed their trades for centuries under the tutelage of the Thousand Sons.

From his balcony on the Pyramid of Photep, Magnus the Red, Primarch of the Thousand Sons, contemplated the future of Prospero. His head still hurt from the ferocity of the nightmare and his eye throbbed painfully in its enlarged socket. He gripped the marble balustrade of the balcony, trying to wish away the visions that assailed him in the night and now chased him into the daylight. Mysteries of the night were revealed in the light of day, but these visions of darkness could not be dragged out so easily.

For as long as Magnus could remember, he had been cursed and blessed with a measure of foresight, and his allegorical interpretation of the Athanaeum ablaze troubled him more than he liked to admit.

He poured himself some wine from a silver pitcher, rubbing a copper-skinned hand through his mane of fiery red hair. The wine helped dull the ache in his heart as well as his head, but he knew it was only a temporary solution. Events were now in motion that he had the power to shape and though much of what he had seen was madness and turmoil, and made no sense, he could make out enough to know that he had to make a decision soon - before events spiralled out of control.

Magnus turned from the view over Tizca and made his way back inside the pyramid, pausing as he caught sight of his reflection in the gleaming silver panels. Huge and red-skinned, Magnus was a towering giant with a lustrous mane of red hair. His patrician features were noble and just, his single eye golden and flecked with crimson. Where his other eye would have sat was blank and empty, though a thin scar ran from the bridge of his nose to the edge of his cheekbone.

Cyclopean Magnus they called him, or worse. Since their inception, the Thousand Sons had been viewed with suspicion for embracing powers that others were afraid of. Powers that, because they were not understood, were rejected as being somehow unclean: rejected ever since the Council of Nikaea.

Magnus threw down his goblet, angry at the memory of his humbling at the feet of the Emperor, when he had been forced to renounce the study of all things sorcerous for fear of what he might learn. Such a notion was surely ridiculous, for was his father's realm not founded on the pursuit of knowledge and reason? What harm could study and learning do?

Though he had retreated to Prospero and sworn to renounce such pursuits, the Planet of the Sorcerers had one vital attribute that made it the perfect place for such studies - it was far from the prying eyes of those who said he dabbled with powers beyond his control.

Magnus smiled at the thought, wishing he could show his persecutors the things he had seen, the wonders and the beauty of what lived beyond the veil of reality. Notions of good and evil fell by the wayside next to such power as dwelled in the warp, for they were the antiquated concepts of a religious society, long cast aside.

He stooped to retrieve his goblet and filled it once more before returning to his chambers and taking a seat at his desk. Inside it was cool and the scent of various inks and parchments made him smile. The wide chamber was walled with bookshelves and glass cabinets, filled with curios and remnants of lost knowledge gleaned from conquered worlds. Magnus himself had penned many of the texts in this room, though others had contributed to this most personal of libraries - Phosis T'kar, Ahriman and Uthizzar to name but a few.

Knowledge had always been a refuge for Magnus, the intoxicating thrill of rendering the unknown down to its constituent parts and, by doing so, rendering it knowable. Ignorance of the universe's workings had created false gods in man's ancient past, and the understanding of them was calculated to destroy them. Such was Magnus's lofty goal.

His father denied such things, kept his people ignorant of the true powers that existed in the galaxy, and though he promulgated a doctrine of science and reason, it was naught but a lie, a comforting blanket thrown over humanity to shield them from the truth.

Magnus had looked deep into the warp, however, and knew different.

He closed his eye, seeing again the darkness of the corrupt chamber, the glitter sheen of the sword, and the blow that would change the fate of the galaxy. He saw death and betrayal, heroes and monsters. He saw loyalty tested, and found wanting and standing firm in equal measure. Terrible fates awaited his brothers and, worst of all, he knew that his father was utterly ignorant of the doom that threatened the galaxy.

A soft knocking came at his door and the red-armoured figure of Ahriman entered, holding before him a long staff topped with a single eye.

'Have you decided yet, my lord?' asked his chief librarian, without preamble. 'I have, my friend,' said Magnus.

'Then shall I gather the coven?'

'Yes,' sighed Magnus, 'in the catacombs beneath the city. Order the thralls to assemble the conjunction and I shall be with you presently.'

'As you wish, my lord,' said Ahriman.

'Something troubles you?' asked Magnus, detecting an edge of reticence in his old friend's tone.

'No, my lord, it is not my place to say'

'Nonsense. If you have a concern then I give you leave to voice it'

'Then may I speak freely?'

'Of course,' nodded Magnus.

'What troubles you?'

Ahriman hesitated before answering. 'This spell you propose is dangerous, very dangerous. None of us truly understand its subtleties and there may be consequences we do not yet foresee.'

Magnus laughed. 'I've not known you shirk from the power of a spell before, Ahriman. When manipulating power of this magnitude there will always be unknowns, but only by wielding it can we bring it to heel. Never forget that we are the masters of the warp, my friend. It is strong, yes, and great power lives within it, but we have the knowledge and means to bend it to our will do we not?'

'We do, my lord,' agreed Ahriman. 'Why then do we use it to warn the Emperor of what is to come when he has forbidden us to pursue such matters?'

Magnus rose from his seat, his copper skin darkening in anger. 'Because when my father sees that it is our sorcery that has saved his realm, he will not be able to deny that what we do here is important, nay, vital to the Imperium's survival!'

Ahriman nodded, fearful of his primarch's rage, and Magnus softened his tone. 'There is no other way, my friend. The Emperor's palace is warded against the power of the warp and only a conjuration of such power will breach those wards.'

'Then I will gather the coven immediately,' said Ahriman.

'Yes, gather them, but await my arrival before beginning. Horus may yet surprise us.'

Panic, fear, indecision: three emotions previously unknown to Loken seized him as Horus fell. The Warmaster crashed to the ground in slow motion, splashing into the mud as his body went completely limp. Shouts of alarm went up, but a paralysis of inaction held those closest to the Warmaster tightly in its grip, as though time itself had slowed.

Loken stared at the Warmaster lying on the ground before him, inert and corpse-like, unable to believe what he was seeing. The rest of the Mournival stood similarly immobile, rooted to the spot in disbelief. He felt as though the air had become thick and cloying, the cries of fear that spread outwards echoing and distant as though from a holo-picter running too slow.

Only Petronella Vivar seemed unaffected by the inaction that held Loken and his brothers firm. Down on her knees in the mud next to the Warmaster, she was weeping and wailing at him to get back up again.

The knowledge that his commander was down and a mortal woman had reacted before any of the Sons of Horus shamed Loken into action and he dropped to one knee alongside the fallen Horus.

'Apothecary!' shouted Loken, and time snapped back with a crash of shouts and cries.

The Mournival dropped to the ground beside him.

'What's wrong?' demanded Abaddon.

'Commander!' shouted Torgaddon.

'Lupercal!' cried Aximand.

Loken ignored them and forced himself to focus.

This is a battlefield injury and I will treat it as such, he thought.

He scanned the Warmaster's body as the others put their hands on him, pushing the remembrancer out of the way as each struggled to wake their lord and master. Too many hands were interfering, and Loken yelled, 'Stop. Get back!'

The Warmaster's armour was beaten and torn, but Loken could see no other obvious breaches in the armoured plates save where the shoulder guard had been torn away, and where the gaping puncture wound oozed in his chest.

'Help me get his armour off!' he shouted.

The Mournival, bound together as brothers, nodded and, grateful to have a focus for their efforts, instantly obeyed Loken's command. Within moments, they had removed Horus's breastplate and pauldrons and were unstrapping his remaining shoulder guard.

Loken tore off his helmet and cast it aside, pressing his ear to the Warmaster's chest. He could hear the Warmaster's hearts, pounding in a deathly slow double beat.

'He's still alive!' he cried.

'Get out of the way!' shouted a voice behind him, and he turned to rebuke this newcomer before seeing the double helix caduceus symbol on his armour plates. Another apothecary joined the first and the Mournival was unceremoniously pushed aside as they went to work, hissing Narthecium stabbing into the Warmaster's flesh.

Loken stood watching them, impotent and helpless as they fought to stabilise the Warmaster. His eyes filled with tears and he looked around in vain for something to do, something to make him feel he was helping. There was nothing, and he felt like crying out to the heavens for making him so powerful and yet so useless.

Abaddon wept openly, and to see the first captain so unmanned made Loken's fear for the Warmaster all the more terrible. Aximand watched the apothecaries work with a grim stoicism, while Torgaddon chewed his bottom lip and prevented the remembrancer from getting in the way.

The Warmaster's skin was ashen, his lips blue and his limbs rigid, and Loken knew that they must destroy whatever power had felled Horus. He turned and began marching back towards the Glory of Terra, determined that he would take the stricken craft apart, piece by piece if need be.

'Captain!' called one of the apothecaries, a warrior Loken knew as Vaddon. 'Get a Stormbird here now! We need to get him to the Vengeful Spirit.'

Loken stood immobile, torn between his desire for vengeance and his duty to the Warmaster.

'Now, captain!' yelled the apothecary, and the spell was broken.

He nodded dumbly and opened a channel to the captains of the Stormbirds, grateful to have a purpose in this maelstrom of confusion. Within moments, one of the medical craft was inbound and Loken watched, mesmerised, as the apothecaries fought to save the Warmaster.

He could see from the frantic nature of their ministrations that they were fighting an uphill battle, their Narthecium whirring miniature centrifuges of blood and dispensing patches of syn-skin to treat his wounds. Their conversations passed over him, but he caught the odd familiar word here and there. 'Larraman cells ineffective…'

'Hypoxic poisoning…'

Aximand appeared at his side and placed his hand on Loken's shoulder. 'Don't say it, Little Horus,' warned Loken. 'I wasn't going to, Garviel,' said Aximand. 'He'll be alright. There's nothing this place could throw at the Warmaster that'll keep him down for long.'

'How do you know?' asked Loken, his voice close to breaking. 'I just do. I have faith.'

'Faith?'

'Yes,' answered Aximand. 'Faith that the Warmaster is too strong and too stubborn to be brought low by something like this. Before you know it we'll be his war dogs once again.'

Loken nodded as the howling downdraught of a Stormbird snatched his breath away.

The screaming craft hovered overhead, throwing up sheets of water as it circled on its descent. Landing skids deployed and the craft came down amid a spray of muddy water.

Before it had touched down, the Mournival and apothecaries had lifted Horus between them. Even as the assault ramp came down, they were rushing inside, placing the Warmaster on one of the gurneys as the Stormbird's jets fired to lift it from Davin's moon.

The assault ramp clanged shut behind them, and Loken felt the aircraft lurch as the pilot aimed it for the skies. The apothecaries hooked the Warmaster up to medicae machines, jamming needles and hissing tubes into his arms, and placing a feed line of oxygen over his mouth and nose.

Suddenly superfluous, Loken slumped into one of the armoured bucket seats against the fuselage of the aircraft and held his head in his hands.

Across from him, the Mournival did the same.

To say that Ignace Karkasy was not a happy man was an understatement. His lunch was cold, Mersadie Oliton was late and the wine he was drinking wasn't fit to lubricate the gears of an engine. To top it all off, his pen tapped on the thick paper of the Bondsman number 7 without any inspiration flowing. He'd taken to avoiding the Retreat, partly for fear of running into Wenduin again, but mostly because it just depressed him too much. The vandalism done to the bar lent it an incredibly sad and gloomy aspect and, while some of the remembrancers needed the squalor to inspire their work, Karkasy wasn't one of them.

Instead, he relaxed in the sub-deck where most of the remembrancers gathered for their meals, but which was empty for the better part of the day. The solitude was helping him to deal with all that had happened since he'd challenged Euphrati Keeler about her distributing the Lectitio Divinitatus pamphlets - though it certainly wasn't helping him compose any poetry.

She'd been unrepentant when he'd confronted her, urging him to join her in prayer to the God-Emperor, before some kind of makeshift shrine.

'I can't,' he had said. 'It's ridiculous, Euphrati, can't you see that?'

'What's so ridiculous about it, Ig?' she'd asked. 'Think about it, we've embarked upon the greatest crusade known to man. A crusade: a war motivated by religious beliefs!'

'No, no,' he protested, 'it's not that at all. We've moved beyond the need for the crutch of religion, Euphrati and we didn't set out from Terra to take a step backwards into such outmoded concepts of belief. It's only by dispelling the clouds and superstitions of religion that we discover truth, reason and morality.'

'It's not superstition to believe in a god, Ignace,' said Euphrati, holding out another of the Lectitio Divinitatus pamphlets. 'Look, read this and then make up your mind.'

'I don't need to read it,' he snapped, throwing the pamphlet to the deck. 'I know what it will say and I'm not interested.'

'But you have no idea, Ignace. It's all so clear to me now. Ever since that thing attacked me, I've been hiding. In my billet and in my head, but I realise now that all I had to do was allow the light of the Emperor into my heart and I would be healed.'

'Didn't Mersadie and I have anything to do with that?' sneered Karkasy. 'All those hours we spent with you weeping on our shoulders?'

'Of course you did,' smiled Euphrati, coming forward and placing her hands on his cheeks. 'That's why I wanted to give you the message and tell you what I'd realised. It's very simple, Ignace. We create our own gods and the blessed Emperor is the Master of Mankind.'

'Create our own gods?' said Karkasy, pulling away from her. 'No, my dear, ignorance and fear create the gods, enthusiasm and deceit adorn them, and human weakness worships them. It's been the same throughout history. When men destroy their old gods they find new ones to take their place. What makes you think this is any different?'

'Because I feel the Emperor's light within me.'

'Oh, well, I can't argue with that, can I?'

'Spare me your sarcasm, Ignace,' said Euphrati, suddenly hostile. 'I thought you might be open to hearing the good word, but I can see you're just a close-minded fool. Get out, Ignace, I don't want to see you again.'

Thus dismissed, he'd found himself outside in the companionway alone, bereft of a friend he'd only just managed to make. That had been the last time she'd spoken to him. He'd seen her only once since then, and she had ignored his greeting.

'Lost in thought, Ignace?' asked Mersadie Oliton, and he looked up in surprise, shaken from his miserable reverie by her sudden appearance.

'Sorry, my dear,' he said. 'I didn't hear you approach. I was miles away, composing another verse for Captain Loken to misunderstand and Sindermann to discard.'

She smiled, instantly lifting his spirits. It was impossible to be too maudlin around Mersadie, she had a way of making a man realise that it was good to be alive.

'Solitude suits you, Ignace, you're far less susceptible to temptation.'

'Oh I don't know,' he said, holding up the bottle of wine. 'There's always room in my life for temptation. I count it a bad day if I'm not tempted by something or other.'

'You're incorrigible, Ignace,' she laughed, 'but enough of that, what's so important that you drag me away from my transcripts to meet here? I want to be up to date by the time the speartip gets back from the moon.'

Flustered by her directness, Karkasy wasn't sure where to begin and thus opted for the softly-softly approach. 'Have you seen Euphrati around recently?'

'I saw her yesterday evening, just before the Storm-birds launched. Why?'

'Did she seem herself?'

'Yes, I think so. I was a little surprised by the change in her appearance, but she's an imagist. I suppose it's what they do every now and again.'

'Did she try to give you anything?'

'Give me anything? No. Look, what's this all about?'

Karkasy slipped a battered pamphlet across the table towards Mersadie, watching her expression change as she read it and recognised it for what it was.

'Where did you get this?' she asked when she'd finished reading it.

'Euphrati gave it to me,' he replied. 'Apparently she wants to spread the word of the God-Emperor to us first because we helped her when she needed support.'

'God-Emperor? Has she taken leave of her senses?'

'I don't know, maybe,' he said, pouring himself a drink. Mersadie pushed over a glass and he filled that too. 'I don't think she was over her experience in the Whisperheads, even if she made out that she was.'

'This is insane,' said Mersadie. 'She'll have her certification revoked. Did you tell her that?'

'Sort of,' said Karkasy. 'I tried to reason with her, but you know how it is with those religious types, never any room for a dissenting opinion.'

'And?'

'And nothing, she threw me out of her billet after that'

'So you handled it with your usual tact then?'

'Perhaps I could have been more delicate,' agreed Karkasy, 'but I was shaken to know that a woman of intelligence could be taken in by such nonsense'

'So what do we do about it?'

'You tell me. I don't have a clue. Do you think we should tell someone about Euphrati?'

Mersadie took a long drink of the wine and said, 'I think we have to.'

'Any ideas who?'

'Sindermann maybe?'

Karkasy sighed. 'I had a feeling you were going to suggest him. I don't like that man, but he's probably the best bet these days. If anyone can talk Euphrati around it's an iterator.'

Mersadie sighed and poured another couple of drinks. 'Want to get drunk?'

'Now you're talking my language,' said Karkasy.

They swapped stories and memories of less complicated times for an hour, finishing the bottle of wine and sending a servitor to fetch more when it ran out. By the time they'd drained half the second one, they were already planning a great symphonic work of her documentarist findings embellished with his verse.

They laughed and studiously avoided any talk of Euphrati Keeler and the betrayal they were soon to visit upon her.

Their thoughts were immediately dispelled as chiming alarm bells rang out, and the corridor beyond began to fill with hurrying people. At first, they ignored the noise, but as the number of people grew, they decided to find out what was going on. Picking up the bottle and glasses, Karkasy and Mersadie unsteadily made their way to the hatchway where they saw a scene of utter bedlam.

Soldiers and civilians, remembrancers and ship's crew, were heading for the embarkation decks in a hurry. They saw faces streaked with tears, and huddled weeping figures consoling one another in their shared misery.

'What's going on?' shouted Karkasy, grabbing a passing soldier.

The man rounded on him angrily. 'Get off me, you old fool.'

'I just want to know what's happening,' said Karkasy, shocked at the man's venom.

'Haven't you heard?' wept the soldier. 'It's all over the ship.'

'What is?' demanded Mersadie.

'The Warmaster…'

'What about him? Is he alright?'

The man shook his head. 'Emperor save us, but the Warmaster is dead!'

The bottle slipped from Karkasy's hands, shattering on the floor, and he was instantly sober. The Warmaster dead? Surely, there had to be some kind of mistake. Surely, Horus was beyond such concerns as mortality. He faced Mersadie and could see exactly the same thoughts running through her head. The soldier he'd stopped shrugged off his grip and ran down the corridor, leaving the two of them standing there, aghast at such a horrific prospect. 'It can't be true,' whispered Mersadie. 'It just can't be.'

'I know. There must be some mistake.'

'What if there isn't?'

'I don't know,' said Karkasy, 'but we have to find out more.'

Mersadie nodded and waited for him to collect the Bondsman before they joined the hurrying throng as it made its mob-like way towards the embarkation decks. Neither of them spoke during the journey, too busy trying to process the impact of the Warmaster's death. Karkasy felt the muse stir within him at such weighty subject matter, and tried not to despise the fact that it came at such a terrible time.

He spotted the corridor leading to the observation deck adjacent to the launch port from where Stormbirds could be seen deploying, or returning. She resisted his pull until he explained his plan.

'There's no way they're going to let us in,' said Karkasy, out of breath from his exertions. 'We can watch the Stormbirds arrive from here and there's an observation gantry that overlooks the deck itself.'

They darted from the human river making its way to the embarkation deck and followed the arched corridor that led to the observation deck. Inside the long chamber, the wide armoured glass wall showed smudges of starlight and the glinting hulls of distant bulk cruisers belonging to the Army and the Mechanicum. Below them was the chasm-like opening of the embarkation deck, its blinking locator lights flashing an angry red.

Mersadie dimmed the lighting, and the details beyond the glass became clearer.

The yellow brown swell of Davin's moon curved away from them, its surface grimy and smeared with clouds. A bary corona of sickly light haloed the moon and, from here, it looked peaceful.

'I don't see anything,' said Mersadie.

Karkasy pressed himself against the glass to eliminate reflections and tried to see something other than himself and Mersadie. Then he saw it. Like a glimmering firefly, a distant speck of fire was rising out of the moon's corona and heading towards the Vengeful Spirit.

'There!' he said, pointing towards the approaching light.

'Where? Oh, wait, I see it!' said Mersadie, blink-clicking the image of the approaching craft.

Karkasy watched as the light drew nearer, resolving itself into the shape of a speeding Stormbird as it angled its approach to the embarkation deck. Even though Karkasy was no pilot, he could tell that its approach was recklessly rapid, the craft's wings folding in at the last moment as it aimed for the yawning, red-lit hatch.

'Come on!' he said, taking Mersadie's hand and leading the way up the steps to the observation gantry. The steps were steep and narrow, and Karkasy had to stop to get his breath back before he reached the top. By the time they reached the gantry, the Stormbird had already been recovered and its assault ramp was descending.

A host of Astartes gathered around the craft as the Bell of Return began ringing and four warriors emerged, the plates of their armour dented and bloodstained. Between them, they carried a body draped in a Legion banner. Karkasy's breath caught in his throat and he felt his heart turn to stone at the sight.

'The Mournival,' said Mersadie. 'Oh no…'

The four warriors were quickly followed by an enormous gurney upon which lay a partially armoured warrior of magnificent stature.

Even from here, Karkasy could tell that the figure upon the gurney was the Warmaster and though tears leapt unbidden to his eyes at the sight of such a superlative warrior laid low, he rejoiced that the shrouded corpse was not the Warmaster. He heard Mersadie blink clicking the images even though he knew there would be no point, her eyes were similarly misted with tears. Behind the gurney came the remembrancer woman, Vivar, her dress torn and bloody, the fine fabric mud stained and ragged, but Karkasy pushed her from his mind as he saw more warriors rush towards the gurney. Armoured in white plate, they surrounded the Warmaster as he was wheeled through the embarkation deck with great haste, and Karkasy's heart leapt as he recognised them as Legion apothecaries.

'He's still alive…' he said.

'What? How do you know?'

'The apothecaries are still working on him,' laughed Karkasy, the relief tasting like the sweetest wine. They threw themselves into each other's arms, embracing with the sheer relief of the Warmaster's survival.

'He's alive,' sobbed Mersadie. 'I knew he had to be. He couldn't be dead.'

'No,' agreed Karkasy. 'He couldn't.'

They broke apart and sagged against the railings as the Astartes escorted the fallen Warmaster across the deck. As the huge blast doors rumbled open, the masses of people gathered outside surged through in a great wave, their cries of loss and pain audible even through the armoured glass of the observation gantry.

'No,' whispered Karkasy. 'No, no, no.'

The Astartes were in no mood to be slowed by this mass of people, and brutally clubbed them aside as they forced a path through the crowd. The Mournival led the gurney through the crowds, mercilessly clearing a bloody path through the people before them. Karkasy saw men and women cast down, trampled underfoot, and their screams were pitiful to hear.

Mersadie held his arm as they watched the Astartes bludgeon their way from the embarkation deck. They vanished through the blast door and were lost to sight as they rushed towards the medical deck.

'Those poor people…' cried Mersadie, sinking to her knees and looking down on a scene like the aftermath of a battle: wounded soldiers, remembrancers and civilians lay where they had fallen, bleeding and broken, simply because they were unlucky enough to be in the path of the Astartes.

'They didn't care,' said Karkasy, still unable to believe the bloody scenes that he'd just witnessed. 'They've killed those people. It was like they didn't care.'

Still in shock at the casual ease with which the Astartes had punched through the crowd, Karkasy gripped the railings, his knuckles white and his jaw clenched with outrage.

'How dare they?' he hissed. 'How dare they?'

His anger at the scenes below still seethed close to the surface, however, he noticed a robed figure making her way through the carnage below, reaching out to the injured and stunned.

His eyes narrowed, but he recognised the shapely form of Euphrati Keeler.

She was handing out Lectitio Divinitatus pamphlets, and she wasn't alone.

Maloghurst watched the recording from the embarkation deck with a grim expression, watching his fellow Sons of Horus batter their way through the crowds that swarmed around the Warmaster's wracked body. The pict replayed again on the viewer set into the table in the Warmaster's sanctum, and each time he watched it, he willed it to be different, but each time the flickering images remained resolutely the same.

'How many dead?' asked Hektor Varvarus, standing at Maloghurst's shoulder.

'I don't have the final figures yet, but at least twenty one are dead, and many more are badly injured or won't wake from the comas they're in.'

He cursed Loken and the others for their heavy handedness as the image played again, but supposed he couldn't blame them for their ardour. The Warmaster was in a critical condition and no one knew if he would live, so their desperation to reach the medical decks was forgivable, even if many might say that their actions were not.

'A bad business, Maloghurst,' said Varvarus needlessly. 'The Astartes will not come out of this well.'

Maloghurst sighed, and said, 'They thought the Warmaster was dying and acted accordingly.'

'Acted accordingly?' repeated Varvarus. 'I do not think many people will accept that, my friend, once word of this gets out, it will be a crippling blow to morale.'

'It will not get out,' assured Maloghurst. 'I am rounding up everyone who was on that deck and have shut down all non-command vox traffic from the ship.'

Tall and precise, Hektor Varvarus was rake-thin and angular, and his every movement was calculated - traits he carried over into his role as Lord Commander of the Army forces of the 63rd Expedition.

'Trust me, Maloghurst, this will get out. One way or another, it will get out. Nothing remains secret forever. Such things have a habit of wanting to be told and this will be no different.'

'Then what do you suggest, lord commander?' asked Maloghurst.

'Are you genuinely asking me, Mal, or are you just observing a courtesy because I am here?'

'I was genuinely asking,' said Maloghurst, smiling as he realised that he meant it. Varvarus was a canny soldier who understood the hearts and minds of mortal men.

'Then you have to tell people what happened. Be honest.'

'Heads will need to roll,' cautioned Maloghurst. 'People will demand blood for this.'

'Then give it to them. If that's what it takes, give it to them. Someone has to be seen to pay for this atrocity.'

'Atrocity? Is that what we're calling it now?'

'What else would you call it? Astartes warriors have committed murder.'

The enormity of what Varvarus was suggesting staggered Maloghurst, and he lowered himself slowly into one of the chairs at the Warmaster's table.

'You would have me give up an Astartes warrior for this? I cannot do it.'

Varvarus leaned over the table, the decorations and medals of his dress uniform reflecting like gold suns in its black surface.

'Innocent blood has been spilled, and while I can understand the reasons behind the actions of your men, it changes nothing.'

'I can't do it, Hektor,' said Maloghurst, shaking his head.

Varvarus moved to stand next to him. 'You and I both swore the oath of loyalty to the Imperium did we not?'

'We did, but what has that to do with anything?'

The old general locked eyes with Maloghurst and said, 'We swore that we would uphold the ideals of nobility and justice that the Imperium stands for, yes?'

'Yes, but this is different. There were extenuating circumstances…'

'Irrelevant,' snapped Varvarus. 'The Imperium must stand for something, or it stands for nothing. If you turn away from this, then you betray that oath of loyalty. Axe you willing to do that, Maloghurst?'

Before he could answer, there was a soft knocking on the glass of the sanctum and Maloghurst turned to see who disturbed them.

Ing Mae Sing, Mistress of Astropathy, stood before them like a skeletal ghost in a hooded white robe, the upper portions of her face shrouded in shadows.

'Mistress Sing,' said Varvarus, bowing deeply towards the telepath.

'Lord Varvarus,' she replied, her voice soft and feather-light. She returned the lord commander's bow and despite her blindness, inclined her head in precisely the right direction - a talent that never failed to unnerve Maloghurst.

'What is it, Mistress Sing?' he asked, though in truth, he was glad of the interruption.

'I bring tidings that must concern you, Sire Maloghurst,' she said, turning her blind gaze upon him. 'The astropathic choirs are unsettled. They sense a powerful surge in the currents of the warp: powerful and growing.'

'What does that mean?' he asked.

'That the veil between worlds grows thin,' said Ing Mae Sing.

TEN Apothecarion Prayers Confession

Stripped out of his armour and wearing bloody surgical robes, Vaddon was as close to desperate as he had ever been in his long experience as an apothecary of the Sons of Horus. The Warmaster lay before him on the gurney, his flesh exposed to his knives and to the probes of the medicae machines. Oxygen was fed to the Warmaster through a mask, and saline drips pumped fluids into his body in an attempt to normalise his blood pressure. Medicae servitors brought fresh blood for immediate transfusions and the entire theatre fizzed with tension and frantic activity.

'We're losing him!' shouted Apothecary Logaan, watching the heart monitors. 'Blood pressure is dropping rapidly, heart rate spiking. He's going to arrest!'

'Damn it,' cursed Vaddon. 'Get me more Larraman serum, his blood won't clot, and fix up another fluid line.'

A whirring surgical narthecium swung down from the ceiling, multiple limbs clattering as they obeyed Vaddon's shouted commands. Fresh Larraman cells were pumped directly into Horus's shoulder and the bleeding slowed, though Vaddon could see it still wasn't stopping completely. Thick needles jabbed into the Warmaster's arms, filling him with super-oxygenated blood, but their supply was dwindling faster than he would have believed possible.

'Stabilising,' breathed Logaan. 'Heart rate slowing and blood pressure is up.'

'Good,' said Vaddon. 'We've got some breathing room then.'

'He can't take much more of this,' said Logaan. 'We're running out of things we can do for him.'

'I'll not hear that in my theatre, Logaan,' snapped Vaddon. 'We're not going to lose him.'

The Warmaster's chest hiked as he clung to life, his breathing coming in short, hyperventilating gasps, more blood pumping from the wound in his shoulder.

Of the two wounds the Warmaster had suffered, it seemed the least severe, but Vaddon knew it was the one that was killing him. The puncture wound in his chest had practically healed already, ultra sonograms showing that his lung had sealed itself off from the pulmonary system while it repaired itself. The Warmaster's secondary lungs were sustaining him for now.

The Mournival hovered like expectant fathers as the apothecaries worked harder than they had ever worked before. Vaddon had never expected to have the Warmaster for a patient. The primarch's biology was as far beyond that of a normal Astartes warrior as his own was from a mortal man, and Vaddon knew that he was out of his depth. Only the Emperor himself had the knowledge to delve into the body of a primarch with confidence, and the enormity of what was occurring was not lost on him. A green light winked into life on the narthecium machine and he lifted the data-slate from the port in its silver steel surface. Numbers and text scrolled across its glossy surface and though much of it made no sense to him, he felt his spirits fall as what he could comprehend sank in.

Seeing that the Warmaster was stable, he circled the operating slab and joined the Mournival, wishing he had better news for them.

'What's wrong with him?' demanded Abaddon. 'Why is he still lying there?'

'Honestly, first captain, I don't know.'

'What do you mean, "You don't know"?' shouted Abaddon, grabbing Vaddon and slamming him against the theatre wall. Silver trays laden with scalpels, saws and forceps clattered to the tiled floor. 'Why don't you know?'

Loken and Aximand grappled with the first captain as Vaddon felt Abaddon's enormous strength slowly crushing his neck.

'Let go of him, Ezekyle!' cried Loken. 'This isn't helping!'

'You won't let him die!' snarled Abaddon, and Vaddon was amazed to see a terrible fear in the first captain's eyes. 'He is the Warmaster!'

'You think I don't know that?' gasped Vaddon as the others prised Abaddon's grip from his neck. He slid down the wall, already able to feel the swelling in his bruised throat.

'Emperor damn you if you let him die,' hissed Abaddon, stalking the theatre with predatory strides. 'If he dies, I will kill you.'

Aximand led the first captain away from him, speaking soothing words as Loken and Torgaddon helped him to his feet.

'The man's a maniac,' hissed Vaddon. 'Get him out of my theatre, now!'

'He's not himself, apothecary,' explained Loken. 'None of us are.'

'Just keep him away from my team, captain,' warned Vaddon. 'He's not in control of himself, and that makes him dangerous.'

'We will,' Torgaddon promised him. 'Now what can you tell us? Will he survive?'

Vaddon took a moment to compose himself before answering, picking up his fallen data-slate. 'As I said before, I just don't know. We're like children trying to repair a logic engine that's been dropped from orbit. We don't understand even a fraction of what his body is capable of or how it works. I can't even begin to guess what kind of damage it's suffered to have caused this'

'What's actually happening to him?' asked Loken.

'It's the wound in his shoulder; it won't clot. It's bleeding out and we can't stop it. We found some degraded genetic residue in the wound that might be some kind of poison, but I can't be sure.'

'Might it be a bacteriological or a viral infection?' asked Torgaddon. 'The water on Davin's moon was thick with contaminants. I ought to know, I swallowed a flagon's worth of it.'

'No,' said Vaddon. 'The Warmaster's body is, for all intents and purposes, immune to such things'

'Then what is it?'

'This is a guess, but it looks like this particular poison induces a form of anaemic hypoxia. Once it enters the bloodstream, it's absorbed exponentially by the red blood cells, in preference to oxygen. With the Warmaster's accelerated metabolism, the toxin was carried efficiently around his system, damaging his tissue cells as it went, so they were unable to make proper use of the reduced oxygen content.'

'So where did it come from?' asked Loken.

'I thought you said the Warmaster was immune to such things.'

'And so he is, but this is like nothing I've ever seen before… it's as though it's been specifically designed to kill him. It's got precisely the right genetic camouflage to fool his enhanced biological defences and allow it to do the maximum amount of damage. It's a primarch killer - pure and simple.'

'So how do we stop it?'

'This isn't an enemy you can take a bolter or sword to, Captain Loken. It's a poison,' he said. 'If I knew the source of the poisoning, we might be able to do something.'

'Then if we found the weapon that did this, would that be of some help?' asked Loken.

Seeing the desperate need for hope in the captain's eyes, Vaddon nodded. 'Maybe. From the wound shape, it looks like a stab wound from a sword. If you can retrieve the blade, then maybe we can do something for him.'

'I'll find it,' swore Loken. He turned from Vaddon and made his way to the theatre door.

'You're going back there?' asked Torgaddon, running to catch up with him.

'Yes, and don't try to stop me,' warned Loken.

'Stop you?' said Torgaddon. 'Don't be such a drama queen, Garvi. I'm coming with you.'

Recovering a Titan after action in the field was a long and arduous process, full of technical, logistical and manual difficulties. Entire fleets of vessels came down from orbit, bringing huge lifters, enormous diggers and loading machines. The delivery vessels had to be dug from their impact craters, and an army of Mechanicum servitors were required to facilitate the process.

Titus Cassar was exhausted. He'd spent the better part of the day prepping the Titan for its recovery and everything was in readiness for their return to the fleet. Until they were recovered, there wasn't much to do except wait, and that had become the hardest part of all for the men left behind on Davin's moon.

With time to wait, there was time to think, and with time to think, the human mind could conjure all manner of things from the depths of its imagination. Titus still couldn't believe that Horus had fallen. A being of such power, like unto a Titan himself, was not meant to fall in battle - he was invincible, the son of a god.

In the shadow of the Dies Irae, Titus fished out his Lectitio Divinitatus chapbook and, once he was satisfied he was alone, began to read the words there. The badly printed scripture gave him comfort, turning his mind to the glory of the divine Emperor of Mankind.

'Oh Emperor, who is lord and god above us all, hear me in this hour of need. Your servant lies with death's cold touch upon him and I ask you to turn your beneficent gaze his way.'

He fished out a pendant from beneath his uniform jacket as he read. It was a delicately wrought thing of silver and gold that he'd had one of the blank-faced servitors fashion for him. A silver capital ''I'' with a golden starburst at its centre, it represented hope and the promise of a better future.

He held it clasped to his breast as he recited more of the words of the Lectitio Divinitatus, feeling a familiar warmth suffuse him as he repeated the words.

Titus sensed the presence of other people behind him a second too late and turned to see Jonah Aruken and a group of the Titan's crew.

Like him, they were dirty and tired after the fight against the monsters of this place, but unlike him they did not have faith.

Guiltily, he closed his chapbook and waited for Jonah's inevitable barb. No one said anything, and as he looked closer, he saw a brittle edge of sorrow and the need for comfort in the faces of the men before him.

'Titus,' said Jonah Aruken. 'We… uh… that is… the Warmaster. We wondered if…'

Titus smiled in welcome as understood what they'd come for.

He opened his chapbook again and said; 'Let us pray, brothers.'

The medical deck was a sterile, gleaming wilderness of tiled walls and brushed steel cabinets, a warren of soulless glass rooms and laboratories. Petronella had completely lost all sense of direction, bewildered by the hasty summons that had brought her from the moon's surface back to the Vengeful Spirit.

Passing through the bloody embarkation deck, she saw that the upper levels of the ship were in pandemonium as word of the Warmaster's death had spread from vessel to vessel with all the fearsome rapidity of an epidemic.

Maloghurst the Twisted had issued a fleet-wide communique denying that the Warmaster was dead, but hysteria and paranoia had a firm head start on his words. Riots had taken hold aboard several ships as doomsayers and demagogues had arisen proclaiming that these were now the end times. Army units had been ruthlessly quashing such malcontents, but more sprang up faster then they could stop them.

It had been scant hours since the Warmaster's fall, but the 63rd Expedition was already beginning to tear itself apart without him.

Maggard followed Petronella, his wounds bound and sealed with syn-skin by a Legion apothecary on the journey back to the Warmaster's flagship. His skin still had an unhealthy pallor and his armour was dented and torn, but he was alive and magnificent. Maggard was only an indentured servant, but he had impressed her and she resolved to treat him with the respect his talents deserved.

A helmeted Astartes warrior led her through the confusing maze of the medicae deck, eventually indicating that she should enter a nondescript white door marked with a winged staff wrapped in a pair of twisting serpents.

Maggard opened the door for her and she entered a gleaming operating theatre, its circular walls covered, to waist height, in green enamelled tiles. Silver cabinets and hissing, pumping machines surrounded the Warmaster, who lay on the operating slab with a tangled web of tubes and wires attached to his flesh. A stool of gleaming metal sat next to the slab.

Medicae servitors lurked around the circumference of the room, set into niches around the wall, and a gurgling machine suspended above the Warmaster fed fluid and blood into his body.

Her eyes misted to see the Warmaster brought so low, and tears came at this violation of the natural order of things. A giant Astartes warrior in hooded surgical robes approached her and said, 'My name is Apothecary Vaddon, Miss Vivar.'

She brushed her hands across her eyes, conscious of how she must look - her dress torn and caked with mud, her eyes blackened with smudged make-up. She started to hold her hand out for a kiss, but realised how foolish that would be and simply nodded.

'I am Petronella Vivar,' she managed. 'I am the Warmaster's documentarist'

'I know,' said Vaddon.

'He asked for you by name.' Sudden hope flared in her breast. 'He's awake?'

Vaddon nodded. 'He is. If it was up to me, you would not be here now, but I do not disobey the word of the commander, and he desires to speak with you'

'How is he?' she asked.

The apothecary shook his head. 'He fades in and out of lucidity, so do not expect too much of him. If I decide it is time for you to leave, then you leave. Do you understand me?'

'I do,' she said, 'but please, may I speak with him now?'

Vaddon seemed reluctant to let her near the Warmaster, but moved aside and let her pass. She nodded her thanks and took a faltering step towards the operating slab, eager to see the Warmaster, but afraid of what she might find.

Petronella's hand leapt to her mouth to stifle an involuntary gasp at the sight of him. The Warmaster's cheeks were sunken and hollow, his eyes dull and listless. Grey flesh hung from his skull, wrinkled and ancient looking, and his lips were the blue of a corpse.

'Do I look that bad?' asked Horus, his voice rasping and distant.

'No,' she stammered. 'Not at all, I…'

'Don't lie to me, Miss Vivar. If you're to hear my valediction then there must be no deceit between us.'

'Valediction? No! I won't. You have to live.'

'Believe me, there's nothing I'd like more,' he wheezed, 'but Vaddon tells me there's not much chance of that, and I don't intend to leave this life without a proper legacy: a record that says die things that must be said before the end.'

'Sir, your deeds alone stand as an eternal legacy, please don't ask this of me.'

Horus coughed a froth of blood onto his chest, gathering his strength before speaking once more, and his voice was the strong and powerful one she remembered. You told me that it was your vocation to immortalise me, to record the glory of Horus for future generations, did you not?'

'I did,' she sobbed.

'Then do this last thing for me, Miss Vivar,' he said.

She swallowed hard and then fished out the data-slate and mnemo-quill from her reticule, before sitting on the high stool next to the operating slab.

'Very well,' she said at last. 'Let's start at the beginning.'

'It was too much,' began Horus. 'I promised my father I would make no mistakes, and now we have come to this.'

'Mistakes?' asked Petronella, though she suspected she knew the Warmaster's meaning.

'Temba, giving him lordship over Davin,' said Horus. 'He begged me not to leave him behind, claimed it was too much for him. I should have listened, but I was too eager to be away on some fresh conquest.'

'Temba's weakness is not your fault, sir,' she said.

'It is good of you to say that, Miss Vivar, but I appointed him,' said Horus. 'The responsibility lies with me. Throne! Guilliman will laugh when he hears of this: him and the Lion both. They will say that I was not fit to be Warmaster since I could not read the hearts of men.'

'Never!' cried Petronella. 'They wouldn't dare.'

'Oh, they will, girl, believe me. We are brothers, yes, but like all brothers we squabble and seek to outdo one another.'

Petronella could think of nothing to say, the idea of the superhuman primarchs squabbling quite beyond her.

'They were jealous, all of them,' continued Horus. 'When the Emperor named me Warmaster, it was all some of them could do to congratulate me. Angron especially, he was a wild one, and even now I can barely keep him in check. Guilliman wasn't much better. I could tell he thought it should have been him.'

'They were jealous of you?' asked Petronella, unable to believe what the Warmaster was telling her, the mnemo-quill scratching across the data-slate in response to her thoughts.

'Oh yes,' nodded Horus bitterly. 'Only a few of my brothers were gracious enough to bow their heads and mean it. Lorgar, Mortarion, Sanguinius, Fulgrim and Dorn - they are true brothers. I remember watching the Emperor's Stormbird leaving Ullanor and weeping to see him go, but most of all I remember the knives I felt in my back as he went. I could hear their thoughts as clearly as though they spoke them aloud: why should I, Horus, be named Warmaster when there were others more worthy of the honour?'

'You were made Warmaster because you were the most worthy, sir,' said Petronella.

'No,' said Horus. 'I was not. I was simply the one who most embodied the Emperor's need at that time. You see, for the first three decades of the Great Crusade I fought alongside the Emperor, and I alone felt the full weight of his ambition to rale the galaxy. He passed that vision to me and I carried it with me in my heart as we forged our path across the stars. It was a grand adventure we were on, system after system reunited with the Master of Mankind. You cannot imagine what it was like to live in such times, Miss Vivar.'

'It sounds magnificent.'

'It was,' said Horus. 'It was, but it couldn't last. Soon we were being drawn to other worlds where we discovered my brother primarchs. We had been scattered throughout the galaxy not long after our birth and, one by one, the Emperor recovered us all.'

'It must have been strange to be reunited with brothers you had never known.'

'Not as strange as you might think. As soon as I met each one, I had an immediate kinship with him, a bond that not even time or distance had broken. I won't deny that some were harder to like than others. If you ever meet Night Haunter you'll understand what I mean. Moody bastard, but handy in a tight spot when you need some alien empire shitting in its breeches before you attack.

'Angron's not much better, mind, he's got a temper on him like you've never seen. You think you know anger, I tell you now that you don't know anything until you've seen Angron lose his temper. And don't get me started on the Lion.'

'Of the Dark Angels? His is the First Legion is it not?'

'It is,' replied Horus, 'and doesn't he just love to remind everyone of that. I could see in his eyes that he thought he should have been Warmaster because his Legion was the first. Did you know he'd grown up living like an animal in the wilds, little better than a feral savage? I ask you, is that the sort of man you want as your Warmaster?'

'No it's not,' said Horus, answering his own question.

'Then who would you have picked to be Warmaster if not you?' asked Petronella.

Horus appeared to be momentarily perturbed by her question, but said, 'Sanguinius. It should have been him. He has the vision and strength to carry us to victory, and the wisdom to rule once that victory is won. For all his aloof coolness, he alone has the Emperor's soul in his blood. Each of us carries part of our father within us, whether it is his hunger for battle, his psychic talent or his determination to succeed. Sanguinius holds it all. It should have been his…'

'And what part of the Emperor do you carry, sir?'

'Me? I carry his ambition to rule. While the conquest of the galaxy lay before us that was enough, but now we are nearing the end. There is a Kretan proverb that says that peace is always "over there", but that is no longer true: it is within our grasp. The job is almost done and what is left for a man of ambition when the work is over?'

'You are the Emperor's right hand, sir,' protested Petronella. 'His favoured son.'

'No more,' said Horus sadly. 'Petty functionaries and administrators have supplanted me. The War Council is no more and I receive my orders from the Council of Terra now. Once everything in the Imperium was geared for war and conquest, but now we are burdened with eaxectors, scribes and scriveners who demand to know the cost of everything. The Imperium is changing and I'm not sure I know how to change with it.'

'In what way is the Imperium changing?'

'Bureaucracy and officialdom are taking over, Miss Vivar. Red tape, administrators and clerks are replacing the heroes of the age and unless we change our ways and our direction, our greatness as an empire will soon be a footnote in the history books. Everything I have achieved will be a distant memory of former glory, lost in the mists of time like the civilisations of ancient Terra, remembered kindly for their noble past.'

'But surely the Crusade was but the first step towards creating a new Imperium for mankind to rule the galaxy. In such a galaxy we will need administrators, laws and scribes.'

'And what of the warriors who conquered it for you?' snarled Horus. 'What becomes of us? Are we to become gaolers and peacekeepers? We were bred for war and we were bred to kill. That is what we were created for, but we have become so much more than that, I am more than that.'

'Progress is hard, my lord, and people must always adapt to changing times,' said Petronella, uneasy at this change of temper in the Warmaster.

'It is not strange to mistake change for progress, Miss Vivar,' said Horus. 'I was bred with wondrous powers encoded into my very flesh, but I did not dream myself into the man I am today, I hammered and forged myself upon the anvil of battle and conquest. All that I have achieved in the last two centuries will be given away to weak men and women who were not here to shed their blood with us in the dark places of the galaxy. Where is the justice in that? Lesser men will rule what I have conquered, but what will be my reward once the fighting is done?'

Petronella glanced away at Apothecary Vaddon, but he simply watched impassively as she took down Horus's words. She wondered briefly if he was as upset as she was at the Warmaster's anger.

As shocked as she was, her ambitious core realised that she had the makings of the most sensational remembrance imaginable, one that would dispel forever the myth of the Crusade as a united band of brothers forging their destiny among the stars. Horus's words painted a picture of mistrust and disunion that no one had ever dreamed of.

Seeing her expression, Horus reached up with a shaking hand and touched her arm.

'I am sorry, Miss Vivar. My thoughts are not as clear as they ought to be.'

'No,' she said. 'I think they're clearer than ever now.'

'I can tell I'm shocking you. I'm sorry if I have shattered your illusions.'

'I admit I am… surprised by much of what you're saying, sir.'

'But you like it, yes? It's what you came here for?'

She tried to deny it, but the sight of the dying primarch gave her pause and she nodded.

'Yes,' she said. 'It's what I came here for. Will you tell me everything?'

He looked up and met her stare.

'Yes,' he said. 'I will.'

ELEVEN Answers A devil's bargain Anathame

The Thunderhawk's armoured flanks were not as sleek as those of a Stormbird, but it was functional and would take them back to Davin's moon more swiftly than the bigger craft. Tech servitors and Mechanicum flight crew prepped it for launch and Loken willed them to hurry. Each passing second brought the Warmaster closer to death and he wasn't going to allow that to happen.

Several hours had passed since they had brought the Warmaster aboard, but he hadn't cleaned his armour or weapons, preferring to go back the way he'd come out, though he had replenished his ammunition supply. The deck was still slick with the blood of those they had battered from their path and only now, with time to reflect on what they had done, did Loken feel ashamed.

He couldn't remember any of the faces, but he remembered the crack of skulls and the cries of pain. All the noble ideals of the Astartes… What did they mean when they could be so easily cast off? Kyril Sindermann was right, common decency and civil behaviour were just a thin veneer over the animal core that lurked in the hearts of all men… even Astartes.

If the mores of civilised behaviour could so easily be forgotten, what else might be betrayed with impunity in difficult circumstances?

Looking around the deck, Loken could sense a barely perceptible difference. Though hammers still beat, hatches still banged and gumeys laden with ordnance curled through the deck spaces, there was a subdued atmosphere to the embarkation deck, as though the memory of what had happened still lingered on the air.

The blast doors of the deck were shut tight, but Loken could still hear the muffled chants and songs of the crowds gathered outside.

Hundreds of people maintained a candlelit vigil in the wide corridors surrounding the embarkation deck, and filled the observation bays. Perhaps three score watched him from the windowed gantry above. They carried offerings and votive papers inscribed with pleas for the Warmaster's survival, random scribbles and outpourings of feelings.

Quite who these entreaties were directed at was a mystery, but it seemed to give people a purpose, and Loken could appreciate the value of purpose in these dark hours.

The men of Locasta were already onboard, though their journey to the embarkation deck had nearly sparked a stampede of terrified people - the memory of the last time the Astartes had marched through them still fresh and bloody.

Torgaddon and Vipus performed the last pre-launch checks on their men, and all that remained for him to do was to give the word.

He heard footsteps behind him and turned to see the armoured figure of Tybalt Marr, Captain of the 18th Company, approaching him. Sometimes known as ''the Either'' due to his uncanny resemblance to Verulam Moy - who had been known as ''the Or'' - he was cast so firmly in the image of the Warmaster that Loken's breath caught in his throat. He bowed as his fellow captain approached.

'Captain Loken,' said Marr, returning the bow. 'Might I have a word?'

'Of course, Tybalt,' he said. 'I'm sorry about Verulam. He was brave man.'

Marr nodded curtly and Loken could only imagine the pain he must be going through.

Loken had grieved for fallen brothers before, but Moy and Marr had been inseparable, enjoying a symbiotic relationship not unlike identical twins. As friends and brothers, they had fought best as a pair, but once again, Moy had been lucky enough to gain a place in the speartip, and Marr had not.

This time Moy had paid for that luck with his life.

'Thank you, Captain Loken. I appreciate the sentiment,' replied Marr.

'Was there something you wanted, Tybalt?'

'Are you returning to the moon?' asked Marr, and Loken knew exactly why Marr was here. He nodded. 'We are. There may be something there that will help the Warmaster. If there is, we will find it.'

'Is it in the place where Verulam died?'

'Yes,' said Loken. 'I think so.'

'Could you use another sword arm? I want to see where… where it happened.'

Loken saw the aching grief in Marr's eyes and said. 'Of course we could.'

Marr nodded his thanks and they marched up the assault ramp as the Thunderhawk's engines powered up with the shrieking of a banshee's wail.

Aximand watched Abaddon punch the sparring servitor's shoulder, tearing off its sword limb before closing to deliver a series of rapid hammer blows to its torso. Flesh caved beneath the assault, bone and steel broke, and the construct collapsed in a splintered mess of meat and metal.

It was the third servitor Abaddon had destroyed in the last thirty minutes. Ezekyle had always worked through his angst with his fists and this time was no different. Violence and killing was what the first captain had been bred for, but it had become such a way of life to him that it was the only way he knew how to express his frustrations.

Aximand himself had dismantled and reassembled his bolter six times, slowly and methodically laying each part on an oiled cloth before cleaning it meticulously. Where Abaddon unleashed his pain through violence, Aximand preferred to detach his mind through familiar routines. Powerless to do anything constructive to help the commander, they had both retreated to the things they knew best.

'The Master of Armouries will have your head for destroying his servitors like that,' said Aximand, looking up as Abaddon pummelled what was left of the servitor to destruction.

Sweating and breathing hard, Abaddon stepped from the training cage, sweat lathering his body in gleaming sheets and his silver-wrapped topknot slick with sweat. Even for an Astartes, he was huge, muscular and solid as stone. Torgaddon often teased Abaddon joking that he left leadership of the Justaerin to Falkus Kibre because he was too big to fit in a suit of Terminator armour.

'It's what they're for,' snapped Abaddon.

'I'm not sure you're meant to be that hard on them.'

Abaddon shrugged, lifted a towel from his arming chamber and hung it around his shoulders. 'How can you be calm at a time like this?'

'Trust me, I'm not calm, Ezekyle.'

'You look calm.'

'Just because I'm not smashing things with my fists doesn't mean I'm not choleric.'

Abaddon picked up a piece of his armour, and began polishing it, before hurling it aside with an angry snarl.

'Centre your humours, Ezekyle,' advised Aximand. 'It's not good to go too far out of balance, you might not come back.'

'I know,' sighed Abaddon. 'But I'm all over the place: choleric, melancholic, saturnine, all of them at the same time. I can't sit still for a second. What if he doesn't make it, Little Horus? What if he dies?'

The first captain stood and paced the arming chambers, wringing his hands, and Aximand could see the blood rising in his cheeks as his anger and frustration grew once more.

'It's not fair,' growled Abaddon. 'It shouldn't be like this. The Emperor wouldn't let this happen. He shouldn't let this happen.'

'The Emperor hasn't been here for a long time, Ezekyle.'

'Does he even know what's happened? Does he even care anymore?'

'I don't know what to tell you, my friend,' said Aximand, picking up his bolter once more and pressing the catch that released the magazine, seeing that Abaddon had a new target for his impotent rage.

'It's not been the same since he left us after Ullanor,' raged Abaddon. 'He left us to clean up what he couldn't be bothered to finish, and for what? Some damn project on Terra that's more important than us?'

'Careful, Ezekyle,' warned Aximand. 'You're in dangerous territory.'

'It's true though isn't it? Don't tell me you don't feel the same, I know you do.'

'It's… different now, yes,' conceded Aximand.

'We're out here fighting and dying to conquer the galaxy for him and he won't even stand with us out on the frontier. Where is his honour? Where is his pride?'

'Ezekyle!' said Aximand, throwing down his bolter and rising to his feet. 'Enough. If you were anyone else, I would strike you down for those words. The Emperor is our lord and master. We are sworn to obey him.'

'We are pledged to the commander. Don't you remember your Mournival oath?'

'I remember it well enough, Ezekyle,' retorted Aximand, 'better than you it seems, for we also pledged to the Emperor above all primarchs.'

Abaddon turned away and gripped the wire mesh of the training cage, his muscles bulging and his head bowed. With a cry of animal rage, he tore the mesh panel from the cage and hurled it across the training halls, where it landed at the armoured feet of Erebus, who stood silhouetted in the doorway.

'Erebus,' said Aximand in surprise. 'How long have you been standing there?'

'Long enough, Little Horus, long enough.'

Aximand felt a dagger of unease settle in his heart and said, 'Ezekyle was just angry and upset. His humours are out of balance. Don't—'

Erebus waved his hand to brush off Aximand's words, the dim light reflecting from the brushed steel plates of his armour. 'Fear not, my friend, you know how it is between us. We are all lodge members here. If anyone were to ask me what I heard here today, you know what I would tell them, don't you?'

'I can't say.'

'Exactly,' smiled Erebus, but far from being reassured, Aximand suddenly felt beholden to the First Chaplain of the Word Bearers, as though his silence were some kind of bargaining chip.

'Did you come for anything, Erebus?' demanded Abaddon, his choler still to the fore.

'I did,' nodded Erebus, holding out his palm to reveal his silver lodge medal. 'The Warmaster's condition is deteriorating and Targost has called a meeting.'

'Now?' asked Aximand. 'Why?'

Erebus shrugged. 'I can't say.'

They gathered once more in the aft hold of the flagship, travelling the lonely service stairwells to the deep decks of the Vengeful Spirit. Tapers again lit the way and Aximand found himself desperate to get this over with. The Warmaster was dying and they were holding a meeting?

'Who approaches?' asked a hooded figure from the darkness.

'Three souls,' Erebus replied.

'What are your names?' the figure asked.

'Do we need to bother with this now?' snapped Aximand. 'You know it's us, Sedirae.'

'What are your names?' repeated the figure.

'I can't say,' said Erebus.

'Pass, friends.'

They entered the aft hold, Aximand shooting a venomous glance at the hooded Luc Sedirae, who simply shrugged and followed them in. Candles lit the vast, scaffold-framed area as usual, but instead of the lively banter of warriors, a subdued, solemn atmosphere shrouded the hold. All the usual suspects were there: Serghar Targost, Luc Sedirae, Kalus Ekaddon, Falkus Kibre and many more officers and file troopers he knew or recognised… and Maloghurst the Twisted.

Erebus led the way into the hold, moving to stand in the centre of the group as Aximand nodded towards the Warmaster's equerry.

'It's been some time since I've seen you at a meeting,' said Aximand.

'It has indeed,' agreed Maloghurst. 'I have neglected my duties as a lodge member, but there are matters before us that demand my attendance.'

'Brothers,' said Targost, beginning the meeting. 'We live in grim times.'

'Get to the point, Serghar,' snarled Abaddon. 'We don't have time for this.'

The lodge master glared at Abaddon, but saw the first captain's lurking temper and nodded rather than confront him. Instead, he gestured towards Erebus and addressed the lodge as a whole. 'Our brother of the XVII Legion would speak to us. Shall we hear him?'

'We shall,' intoned the Sons of Horus.

Erebus bowed and said, 'Brother Ezekyle is right, we do not have time to stand on ceremony so I will be blunt. The Warmaster is dying and the fate of the Crusade stands on a knife-edge. We alone have the power to save it.'

'What does that mean, Erebus?' asked Aximand.

Erebus paced around the circumference of the circle as he spoke. 'The apothecaries can do nothing for the Warmaster. For all their dedication, they cannot cure him of this sickness. All they can do is keep him alive, and they cannot do that for much longer. If we do not act now, it will be too late.'

'What do you propose, Erebus?' asked Targost.

'The tribes on Davin,' said Erebus.

'What of them?' asked the lodge master.

'They are a feral people, controlled by warrior castes, but then we all know this. Our own quiet order bears the hallmarks of their warrior lodges in its structure and practices. Each of their lodges venerates one of the autochthonic predators of their lands, and this is where our order differs. In my time on Davin during its compliance, I studied the lodges and their ways in search of corruption or religious profanity. I found nothing of that, but in one lodge I found what I believe might be our only hope of saving the Warmaster.'

Despite himself, Aximand became caught up in Erebus's words, his oratory worthy of the iterators, with the precise modulation of tone and timbre to entrance his audience.

'Tell us!' shouted Luc Sedirae.

The lodge took up the cry until Serghar Targost was forced to restore order with a bellowed command.

'We must take the Warmaster to the Temple of the Serpent Lodge on Davin,' declared Erebus. 'The priests there are skilled in the mystic arts of healing, and I believe they offer the best chance of saving the Warmaster.'

'Mystic arts?' asked Aximand. 'What does that mean? It sounds like sorcery.'

'I do not believe it is,' said Erebus, rounding on him, 'but what if it was, Brother Horus? Would you refuse their aid? Would you allow the Warmaster to die just so we can feel pure? Is the Warmaster's life not worth a little risk?'

'Risk, yes? But this feels wrong.'

'Wrong would be not doing all that we could to save the commander,' said Targost.

'Even if it means tainting ourselves with impure magick?'

'Don't get all high and mighty, Aximand,' said Targost. 'We do this for the Legion. There is no other choice.'

'Then is it. already decided?' demanded Aximand, pushing past Erebus to stand in the centre of the circle. 'If so, then why this charade of debate? Why bother even summoning us here?'

Maloghurst limped from Targost's side and shook his head. 'We must all be in accord here, Brother Horus. You know how the lodge operates. If you do not agree to this, then we will go no further and the Warmaster will remain here, but he will die if we do nothing. You know that to be true.'

'You cannot ask this of me,' pleaded Aximand.

'I have to, my brother,' said Maloghurst. 'There is no other way.'

Aximand felt the responsibility of the decision before him crushing him to the floor as every eye in the chamber turned upon him. His eyes meet Abaddon's and he saw that Ezekyle was clearly in favour of doing whatever it took to save the Warmaster.

'What of Torgaddon and Loken?' asked Aximand, trying to buy some time to think. 'They are not here to speak.'

'Loken is not one of us!' shouted Kalus Ekaddon, Captain of the Reaver squads. 'He had his chance to join us, but turned his back on our order. As for Tarik, he will follow our lead in this. There is no time to seek him out.' Aximand looked into the faces of the men around him, and he realised had no choice. He never had from the moment he had walked into the room.

Whatever it took, the Warmaster had to live. It was that simple.

He knew there would be consequences. There always were in a devil's bargain like this, but any price was worth paying if it would save the commander.

He was damned if he would be remembered as die warrior who stood by and let the Warmaster die.

'Very well,' he said at last. 'Let the Lodge of the Serpent do what it can.'

The difference in Davin's moon in the few hours since they had last set foot on it was incredible, thought Loken. The cloying mists and fogs had vanished and the sky was lightening from a musky yellow to bleached white. The stench was still there, but it too was lessened, now just unpleasant rather than overpowering. Had the death of Temba broken some kind of power that held the moon locked in a perpetual cycle of decay?

As the Thunderhawk had skimmed the marshes, Loken had seen that the diseased forests were gone, their trunks collapsed in on themselves without the life-giving corruption holding them together. Without the obscuring mists, it was easy to find the Glory of Terra, though thankfully there was no deathly message coming over the vox this time.

They touched down and Loken led Locasta squad, Torgaddon, Vipus and Marr from the Thunderhawk with the confident strides of a natural leader. Though Torgaddon and Marr had held their captaincies longer than Loken, both instinctively deferred to him on this mission.

'What do you expect to find here, Garvi?' asked Torgaddon, squinting up at the collapsed hulk of the ship. He hadn't bothered to find a new helmet and his nose wrinkled at the stench of the place.

'I'm not sure,' he answered. 'Answers, maybe; something to help the Warmaster.'

Torgaddon nodded. 'Sounds good to me. What about you, Marr? What are you looking for?'

Tybalt Marr didn't answer, racking the slide of his bolter and marching towards the crashed vessel. Loken caught up with him and grabbed his shoulder guard.

'Tybalt, am I going to have a problem with you here?'

'No. I just want to see where Verulam died,' said Marr. 'It won't be real until I've seen the place. I know I saw him in the mortuary, but that wasn't a dead man. It was just like looking in a mirror. You understand?'

Loken didn't, but he nodded anyway. 'Very well, take up position in the file.'

They marched towards the dead ship, clambering up the broken ramps of debris to the gaping holes torn in its side.

'Damn, but it feels like a lifetime since we were fighting here,' said Torgaddon.

'It was only three or four hours ago, Tarik,' Loken pointed out.

'I know, but still…'

Eventually they reached the top of the ramp and penetrated the darkness of the ship, the memory of the last time he had done this and what he had found at the end of the journey still fresh in Loken's mind.

'Stay alert. We don't know what else might still be alive in here.'

'We should have bombed the wreck from orbit,' muttered Torgaddon.

'Quiet!' hissed Loken. 'Didn't you hear what I said?'

Tarik raised his hands in apology and they pressed on through the groaning wreck, along darkened hallways, flickering companionways and stinking, blackened corridors. Vipus and Loken led the way, with Torgaddon and Marr guarding the rear. The shadow-haunted wreck had lost none of its power to disturb, though the disgusting, organic growths that coated every surface with glistening wetness now seemed to be dying - drying up and cracking to powder.

'What's going on in here?' asked Torgaddon. 'This place was like the hydroponics bay a few hours ago, now it's…'

'Dying,' completed Vipus. 'Like those trees we saw earlier.'

'More like dead,' said Marr, peeling the husk of one of the growths from the wall.

'Don't touch anything,' warned Loken. 'Something in this ship had the power to harm the commander and until we know what that was, we touch nothing.'

Marr dropped the remains and wiped his hand on his leg as they journeyed deeper inside the ship. Loken's memory of their previous route was faultless and they soon reached the central spine and the route to the bridge.

Shafts of light speared in through holes in the hull and dust motes floated in the air like a glittering wall. Loken led on, ducking beneath protruding bulkheads and sparking cables as they reached their ultimate destination.

Loken could smell Eugan Temba long before they saw him, the reek of his putrefaction and death thick even beyond the bridge. They made their way cautiously onto the bridge, and Loken sent his warriors around the perimeter with directional chops of his hand.

'What are we going to do about those men up there?' asked Vipus, pointing to the dead soldiers stitched to the banners hanging from the roof. 'We can't just leave them like that.'

'I know, but we can't do anything for them just now,' said Loken. 'When we destroy this hulk, they'll be at rest.'

'Is that him?' asked Marr, pointing at the bloated corpse.

Loken nodded, raising his bolter and advancing on the body. A rippling motion undulated beneath the corpse's skin, and Temba's voluminous belly wobbled with internal motion. His flesh was stretched so tightly over his frame that the outlines of fat maggots and larvae could be seen beneath his parchment skin.

'Throne, he's disgusting,' said Marr. 'And this… thing killed Verulam?'

'I assume so,' replied Loken. 'The Warmaster didn't say exactly, but there's nothing else here is there?'

Loken left Marr to his grief and turned to his warriors, saying, 'Spread out and look for something, anything that might give us some clue as to what happened here.'

'You don't have any idea what we're looking for?' asked Vipus.

'No, not really,' admitted Loken. 'A weapon maybe.'

'You know we're going to have to search that fat bastard don't you?' Torgaddon pointed out. 'Who's the lucky sod who gets to do that?'

'I thought that'd be something you'd enjoy, Tarik.'

'Oh no, I'm not putting so much as a finger near that thing.'

'I'll do it,' said Marr, dropping to his knees and peeling away the sodden remnants of Eugan Temba's clothing and flesh.

'See?' said Torgaddon, backing away. 'Tybalt wants to do it. I say let him.'

'Very well. Be careful, Tybalt,' said Loken before turning away from the disgusting sight of Marr pulling apart Temba's corpse.

His men began searching the bridge and Loken climbed the steps to the captain's throne, staring out over the crew pits, now filled with all manner of vile excrescences and filth. It baffled Loken how such a glorious ship and a man of supposedly fine character could come to such a despicable end.

He circled the throne, pausing as his foot connected with something solid.

He bent down and saw a polished wooden casket. Its surfaces were smooth and clean, and it was clearly out of place in this reeking tomb. Perhaps the length and thickness of a man's arm, the wood was rich brown with strange symbols carved along its length. The lid opened on golden hinges and Loken released the delicate catch that held it shut.

The casket was empty, padded with a red velvet insert, and as he stared at its emptiness, Loken realised how thoughtless he'd been in opening it. He ran his fingers along the length of the casket, tracing the outline of the symbols, seeing something familiar in their elegantly cursive forms.

'Over here!' shouted one of Locasta, and Loken quickly gathered up the casket and made his way towards the source of the call. While Tybalt Marr disassembled the traitor's rotten body, Astartes warriors surrounded something that gleamed on the deck.

Loken saw that it was Eugan Temba's severed arm, the fingers still wrapped around the hilt of a strange, glittering sword with a blade that looked like grey flint.

'It's Temba's arm right enough,' said Vipus, reaching down to lift the sword.

'Don't touch it,' said Loken. 'If it laid the Warmaster low, I don't want to know what it could do to us.'

Vipus recoiled from the sword as though it were a snake.

'What's that?' asked Torgaddon, pointing at the casket.

Loken dropped to his haunches, laying the casket next to the sword, unsurprised when he saw that the sword would fit snugly inside.

'I think it once contained this sword.'

'Looks pretty new,' said Vipus. 'And what's that on the side? Writing?'

Loken didn't answer, reaching out to prise Temba's dead fingers from the sword hilt. Though he knew it was absurd, he grimaced with each finger he pried loose, expecting the hand to leap to life and attack him.

Eventually, the sword was free, and Loken gingerly lifted the weapon.

'Careful,' said Torgaddon.

'Thanks, Tarik, and here was me about to throw it.'

'Sorry.'

Loken slowly lowered the sword into the casket. The handle tingled and he had felt a curious sensation as he had said Tarik's name, a sense of the monstrous harm the weapon could inflict. He snapped the lid shut, letting out a pent-up breath.

'How in the name of Terra did someone like Temba get hold of a weapon like that?' asked Torgaddon. 'It didn't even look human-made.'

'It's not,' said Loken as the familiarity of the symbols on the side of the casket fell horribly into place. 'It's kinebrach.'

'Kinebrach?' asked Torgaddon. 'But weren't they—'

'Yes,' said Loken, carefully lifting the casket from the deck. 'This is the anathame that was stolen from the Hall of Devices on Xenobia.'

The word went out across the Vengeful Spirit at the speed of thought, and weeping men and women lined their route. Hundreds filed each passageway as the Astartes bore the Warmaster on a bier of kite-shaped shields. Clad in his ceremonial armour of winter white with burnished gold trims and the glaring red eye, the Warmaster's hands were clasped across his golden sword, and a laurel wreath of silver sat upon his noble brow.

Abaddon, Aximand, Luc Sedirae, Serghar Targost, Falkus Kibre and Kalus Ekaddon carried him, and behind the Warmaster came Hektor Varvarus and Maloghurst. Each one wore shining armour and their company cloaks billowed behind them as they walked. Heralds and criers announced the route of the cortege, and there was no repeat of the bloody scene on the embarkation deck as the Astartes took this slow march with the beloved leader who had fought beside them since the earliest days of the Crusade. They wept as they marched, each one painfully aware that this might be the Warmaster's last journey.

In lieu of flowers, the people threw torn scraps of tearstained paper, each with words of hope and love written on them. Shown that the Warmaster still lived, his people burned herbs said to have healing properties, hanging them from smoking censers all along the route, and from somewhere a band played the Legion March.

Candles burned with a sweet smell and men and women, soldiers and civilians, tore at themselves in their grief. Army banners lined the route, each dipped out of respect for the Warmaster, and pleading chants followed the procession until at last they came to the embarkation deck. Its vast gateway was wreathed in parchment, every square centimetre of bulkhead covered with messages for the Warmaster and his sons.

Aximand was awed by the outpouring of sorrow and love for the Warmaster, the scale of people's grief at his wounding beyond anything in his experience. To him the Warmaster was a figure of magnificence, but first and foremost, he was a warrior - a leader of men and one of the Emperor's chosen.

To these mortals, he was so much more. To them, the Warmaster was a symbol of something noble and heroic beyond anything they could ever aspire to, a symbol of the new galaxy they were forging from the ashes of the Age of Strife.

Horus's very existence promised an end to the suffering and death that had plagued humanity for centuries.

Old Night was drawing to a close and, thanks to heroes like the Warmaster, the first rays of a new dawn were breaking on the horizon.

All that was under threat now, and Aximand knew he had made the right choice in allowing the others to take Horus to Davin. The Lodge of the Serpent would heal the Warmaster, and if that involved powers he might once have condemned, then so be it.

The die was cast and all he had left to cling to was his faith that the Warmaster would be restored to them. He smiled as he remembered something the Warmaster had said to him on the subject of faith. The Warmaster had typically delivered his words of wisdom at a wholly inappropriate time - right before they had leapt from the belly of a screaming Stormbird into the green skin city on Ullanor.

'When you have come to the edge of all that you know and are about to drop off into the darkness of the unknown, faith is knowing that one of two things will happen,' the Warmaster had told him.

'And what are they?' he had asked.

'That there will be something solid to stand on or you'll be taught to fly,' laughed Horus as he jumped.

The memory made the tears come all the harder as the huge iron gate of the embarkation deck rumbled closed behind them and the Astartes marched towards the Warmaster's waiting Stormbird.

TWELVE Agitprop Brothers in suspicion Serpent and moon

Slipping across the page like a snake, the nib of Ignace Karkasy's pen moved as though it had a mind of its own. For all the conscious thought he was putting into the words, it might as well have. The muse was well and truly upon him, his stream of consciousness flowing into a river of blood as he retold the diabolical events on the embarkation deck. The meter played in his head like a symphony, every stanza of every canto slipping into place as if there could be no other possible arrangement of verse.

Even in his heyday of Ocean Poems or Reflections and Odes he had not felt this inspired. In fact, now that he looked back on them, he hated them for their frippery, their unconscionable navel gazing and irrelevance to the galaxy at large. These words, these thoughts that now poured from him, this was what mattered, and he cursed that it had taken him this long to discover it.

The truth was what mattered. Captain Loken had told him as much, but he hadn't heard him, not really. The verses he'd written since Loken had begun his sponsorship of him were paltry things, unworthy of the man who had won the Ethiopic Laureate, but that was changing now.

After the bloodbath on the embarkation deck, he'd returned to his quarters, grabbed a bottle of Terran wine and made his way to the observation deck. Finding it thronged with wailing lunatics, he'd repaired to the Retreat, knowing that it would be empty.

The words had poured out of him in a flood of righteous indignation, his metaphors bold and his lyric unflinching from the awful brutality he'd witnessed. He'd already used up three pages of the Bondsman, his fingers blotted with ink and his poet's soul on fire.

'Everything I've done before this was prologue,' he whispered as he wrote.

Karkasy paused in his work as he pondered the dilemma: the truth was useless if no one could hear it. The facilities set aside for the remembrancers included a presswork where they could submit their work for large-scale circulation. It was common knowledge that much of what that passed through it was vetted and censored, and so few made use of it. Karkasy certainly couldn't, considering the content of his new poetry.

A slow smile spread across his jowly features and he reached into the pocket of his robes and pulled out a crumpled sheet of paper - one of Euphrati Keeler's Lectitio Divinitatus pamphlets - and spread it out flat on the table before him with the heel of his palm.

The ink was smeared and the paper reeked of ammonia, clearly the work of a cheap mechanical bulk-printer of some kind. If Euphrati could get the use of one, then so could he.

Loken permitted Tybalt Marr to torch the body of Eugan Temba before they left the bridge. His fellow captain, streaked with gore and filth, played the burning breath of a flame unit over the monstrous corpse until nothing but ashen bone remained. It was small satisfaction for the death of a brother, not nearly enough, but it would have to do. Leaving behind the smouldering remains, they retraced their footsteps back through the Glory of Terra.

The light was fading on Davin's moon by the time they reached the outside, the planet above a pale yellow orb hanging low in the dusky sky. Loken carried the anathame in its gleaming wooden casket, and his warriors followed him from the wreck without any words spoken.

A great rumbling vibration gripped the moon as a trio of towering columns of light and smoke climbed towards the heavens from the Imperial deployment zone where this whole misadventure had started. Loken watched the incredible spectacle of the war machines of the Legio Mortis returning to their armoured berths in orbit, and silently thanked their crews for their aid in the fight against the dead things.

Soon all that was visible of the Titans' carriers was a diffuse glow on the horizon, and only the lap of water and the low growling of the waiting Thunderhawk's engines disturbed the silence. The desolate mudflats were empty for kilometres around, and as Loken made his way down the slope of rubble, he felt like the loneliest man in the galaxy.

Some kilometres away, he could see specks of blue light following the Titan carriers as Army transports ferried the last remaining soldiers back to their bulk transporters.

'We'll soon be done here, eh?' said Torgaddon.

'I suppose,' agreed Loken. 'The sooner the better.'

'How do you suppose that thing got here?'

Loken didn't have to ask what his brother meant, and shook his head, unwilling to share his suspicions with Torgaddon yet. As much as he loved him, Tarik had a big mouth, and Loken didn't want to put his quarry to flight.

'I don't know, Tarik,' said Loken as they reached the ground and made their way towards the Thunderhawk's lowered assault ramp. 'I don't think we'll ever know.'

'Come on, Garvi, it's me!' laughed Torgaddon. 'You're so straight up and down, and that makes you a really terrible liar. I know you've got some idea of what happened. So come on, spill it.'

'I can't, Tarik, I'm sorry,' said Loken. 'Not yet anyway. Trust me. I know what I'm doing.'

'Do you really?'

'I'm not sure,' admitted Loken. 'I think so. Throne, I wish the Warmaster were here to ask.'

'Well he's not,' stated Torgaddon, 'so you're stuck with me.'

Loken stepped onto the ramp, grateful to be off the marshy surface of the moon, and turned to face Torgaddon. 'You're right, I should tell you, and I will, soon. I just need to figure some things out first.'

'Look, I'm not stupid, Garvi,' said Torgaddon, leaning in close so that none of the others could hear. 'I know the only way this thing could have got here is if someone in the expedition brought it. It had to have been here before we arrived. That means there was only one person who was with us on Xenobia and could have got here before we did. You know who I'm talking about.'

'I know who you're talking about,' agreed Loken, pulling Torgaddon aside as the rest of the warriors embarked upon the Thunderhawk. 'What I can't figure out is why? Why go to all the trouble of stealing this thing and then bringing it here?'

'I'm going to break that son of a bitch in two if he had something to do with what's happened to the Warmaster,' snarled Torgaddon.

'The Legion will have his hide.'

'No,' hissed Loken, 'not yet. Not until we find out what this is all about and if anyone else is involved. I just can't believe that someone would dare try and move against the Warmaster.'

'Is that what you think is happening, a coup? You think that one of the other primarchs is making a play for the role of Warmaster?'

'I don't know, it all sounds too far fetched. It sounds like something from one of Sindermann's books.'

Neither man said anything. The idea that one of the eternal brotherhood of primarchs might be attempting to usurp Horus was incredible, outrageous and unthinkable, wasn't it?

'Hey,' called Vipus from inside the Thunderhawk. 'What are you two conspirators plotting?'

'Nothing,' said Loken guiltily. 'We were just talking.'

'Well finish up. We need to go, now!'

'Why, what is it?' asked Loken as he climbed aboard.

'The Warmaster,' said Vipus. 'They're taking him to Davin.'

The Thunderhawk was in the air moments later, lifting off in a spray of muddy water and a flare of blue-hot jet fire. The gunship circled the massive wreck, gaining altitude and speed as it turned towards the sky.

The pilot firewalled the engines and the gunship roared up into the darkness.

The great red orb of the sun was dipping below the horizon and hot, dry winds rising from the plains below made it a bumpy ride as they re-entered Davin's atmosphere. The continental mass swelled through the armoured glass of the cockpit, dusty and brown and dry. Loken sat up front in the cockpit with the pilots and watched the avionics panel as the red blip that represented the location of the Warmaster's Stormbird drew ever closer.

Far below them, he could see the. glittering lights of the Imperial deployment zone where they had first made planetfall on Davin, a wide circle of arc lights, makeshift landing platforms and defensive positions. The pilot brought them in at a steep angle, speed more important to Loken than any notion of safe flight, and they streaked past scores of other landing craft on their way to the surface.

'Why so many?' wondered Loken as their flight levelled out and they shot past the wide circle of light, seeing soldiers and servitors toiling to expedite the approach of so many landing craft.

'No idea,' said the pilot, 'but there's hundreds of them coming down from the fleet. Looks like a lot of people want to see Davin.'

Loken didn't reply, but the sight of so many landing craft en route to Davin was yet another piece of the puzzle that he didn't understand. The vox networks were jammed with insane chatter, weeping voices and groups claiming that the end was coming, while yet others gave thanks to the divine Emperor that his chosen champion would soon rise from his deathbed.

None of it made any sense. He'd tried to make contact with the Mournival, but no one was answering, and a terrible foreboding filled him when he couldn't even reach Maloghurst on the Vengeful Spirit.

Their flight soon carried them beyond the Imperial position, and Loken saw a ribbon of light stretching north from the landing zone. A host of pinpricks of light pierced the darkness, and Loken ordered the pilot to fly lower and reduce speed.

A long column of vehicles: tanks, supply trucks, transporter flatbeds and even some civilian traffic, drove along the dusty hardpan, each one swamped with people, and all heading to the mountains as fast as their engines could carry them. The Thunderhawk powered on through the fading light of day, soon losing sight of the column of vehicles that was heading in the same direction.

'How long until we reach the Warmaster's position?' he asked.

'At current speed, maybe ten minutes or so,' answered the pilot.

Loken tried to collect his thoughts, but they had long since derailed in the midst of all this madness. Ever since leaving the interex, his mind had been a whirlpool, sucking in every random thought and spitting it out with barbs of suspicion. Could it be that he was still suffering the after-effects of what had happened to Jubal? Might the power, unlocked beneath the Whisperheads, be tainting him so that he jumped at shadows where none existed?

He might have been able to believe that, but for the presence of the anathame and his certainty that First Chaplain Erebus had lied to him on the voyage to Davin.

Karkasy had said that Erebus wanted Horus to come to Davin's moon, and his undoubted complicity - in the theft of the anathame could lead to only one conclusion. Erebus had wanted Horus to be killed here.

That didn't make any sense either. Why go to such convoluted lengths just to kill the Warmaster, surely there had to be more to it than that…

Facts were slowly accumulating, but none of them fit, and still he had no idea why any of this was happening, only that it was, and that it was by the artifice of human design. Whatever was going on, he would uncover the conspiracy and make those involved pay with their lives.

'We're coming up on the Warmaster's Stormbird,' called the pilot.

Loken shook himself from his venomous reverie. He hadn't been aware of time passing, but immediately turned his attention to what lay beyond the armoured glass of the cockpit.

Tall mountain peaks surrounded them, jagged cliffs of red stone, veined with gleaming strata of gold and quartz. They followed the course of an ancient causeway along the valley, its flagstones split and cracked with the passing of the centuries. Statues of long-dead kings lined the processional way, and toppled columns littered this forgotten highway like fallen guardians. Shadows plumbed the depths of the valley along which they flew and in a gap ahead, he could see a reflected glow in the brazen sky.

The pilot dropped their speed and the gunship flew through the gap into a colossal crater gouged from the landscape like an enormous, flat-bottomed basin. The sheer sides of the crater soared above them, its diameter thousands of metres across.

A huge stone building stood at its centre, carved from the same rock as the mountains and bathed in the light of a thousand flaming torches. The Thunderhawk circled the structure and Loken saw that it was a giant octagonal building, each corner shaped like the bastion of a fortress. Eight towers surrounded a wide dome at its centre and flames burned from their tops.

Loken could see the Warmaster's Stormbird below them, a multitude of torchbearers surrounding it, hundreds, maybe even thousands of people. A clear path stretched from the Stormbird towards the cyclopean archway that led into the building, and Loken saw the unmistakable form of the Warmaster being borne by the Sons of Horus towards it.

'Take us down. Now!' shouted Loken. He rose, made his way back to the crew compartment and snatched his bolter from the rack.

'What's up?' asked Vipus. 'Trouble?'

'Could be,' said Loken, turning to address all the warriors aboard the gunship. 'Once we disembark, take your lead from me.'

His warriors had efficiently prepped for a combat disembarkation, and Loken felt the motion of the Thunderhawk change as it slowed and came in to land. The internal light changed from red to green and the craft slammed hard into the ground. The assault ramp dropped and Loken led the way out, marching confidently towards the building.

Night had fallen, but the air was hot, and the sour fragrances of bitter blossoms filled the air with a beguiling, aromatic scent. He led his men onwards at a quick march. Many of the torchbearers turned quizzically towards them, and Loken now saw that these were the indigenous inhabitants of Davin.

The Davinites were more wiry than most mortal men, tall and hirsute with thin limbs, and elaborate topknots worn in a style similar to Abaddon's. They wore long capes of shimmering, patterned scales, banded armour - of the same lacquered scales - and most were armed with cross-belts of daggers and primitive looking black powder pistols. They parted before the advance of the Astartes, heads bowed in supplication, and it forcibly struck Loken just how close to deviancy these creatures appeared to be.

He hadn't paid much attention to the Davinites the first time he'd landed. He was just a squad captain more concerned with obeying orders and completing the tasks assigned to him than paying attention to the locals. Even this time, his attention had been elsewhere, and the almost bestial appearance of the Davinites had more or less slipped past his notice.

Surrounded by hundreds of the planet's inhabitants, their divergence from the human genome was unmistakeable, and Loken wondered how they had avoided extermination six decades ago, especially since it had been the Word Bearers who had made first contact with Davin - a Legion not noted for its tolerance of anything beyond the norm.

Loken was reminded of Abaddon's furious argument with the Warmaster over the question of the interex, and of how the first captain had demanded that they make war upon them for their tolerance of xenos breeds. If anything, Davin was far more of a textbook case for war, but somehow that hadn't happened.

The Davinites were clearly of human gene-stock, but this offshoot of humanity had diverged into a species almost all of its own. The wide spacing of their features, the dark eyes without pupils and the excessive, almost simian volume of thick hair on their faces and arms put Loken more in the mind of the stable-bred mutants some regiments of the Imperial Army employed. They were crude creatures with the intelligence to swing a sword or fire a clumsy rifle, but not much else.

Loken did not approve of the practice, and though the inhabitants of Davin were clearly possessed of a greater level of intelligence than such beasts, their appearance did not reassure him as to what was going on.

He put the Davinites from his mind as he approached a massive set of steps carved into the rock and lined with statues of coiling serpents and flaming braziers. Three narrow channels filled with rushing water divided the stairs, one to either side and one down the centre.

The Warmaster and his bearers were out of sight on the next level, and Loken led his warriors up the processional stairs, taking them three at a time as he heard a monstrous grinding of stone up ahead. The image of vast, monolithic doors appeared unbidden in his mind and he said, 'We have to hurry.'

Loken neared the top of the steps, the flickering coal braziers casting a ruddy glow over the statues that glinted from the serpents' scales and quartz-chip eyes. The last rays of the dying sun caught the twisting snakes carved around the pillars, making them seem alive, as if slowly descending to the steps. The effect was unsettling, and Loken opened his suit link again, saying, 'Abaddon, Aximand? Can either of you hear me? Respond.'

His earpiece hissed with static, but his hails received no answers and he picked up the pace.

He reached the top of the steps at last, and emerged onto a moonlit esplanade of yet more serpentine statues atop pillars that lined a narrowing roadway leading towards a giant, arched gateway in the face of the massive edifice. Wide gates of carved and beaten bronze with a glistening, spiralled surface rambled as they swung closed, and Loken felt his skin crawl at the sight of that dread portal, its yawning darkness rich with the promise of ancient, primal power.

He could see a group of Astartes warriors standing before it, watching as the monsttous gate shut. Loken could see no sign of the Warmaster.

'Pick up the pace, battle march,' he ordered, and began the loping, ground-eating stride that the Astartes adopted when there was no vehicle support. Marching at this speed was sustainable over huge distances and still allowed a warrior to fight at the end of it. Loken prayed that he wouldn't be required to fight at the end of this march.

As he drew closer to the gates he saw that, far from being etched with meaningless spirals, each was carved with all manner of images and scenes. Looping serpents twisted from one leaf to another, others circled and swallowed their tails, and yet more were depicted intertwined as though mating.

Only when the gate slammed shut with a thunderous boom of metal did he see the full image. Unlike the commander, Loken was no student of art; nevertheless, he was awed by the full impact of the images worked onto the sealed gateway. Central to its imagery was a great tree with spreading branches, hanging with fruit of all description. Its three roots stretched out beyond the base of the gates and into a wide circular pool that fed the streams running the length of the esplanade, before cascading down the grand stairs.

Twin snakes coiled around the tree, their heads entwined in the branches above, and Loken was struck by its similarity to the symbol borne upon the shoulder guards of the Legion apothecaries.

Seven warriors stood at the edge of the pool of water, before the massive gate. They were armoured in the green of the Sons of Horus, and Loken knew them all: Abaddon, Aximand, Targost, Sedirae, Ekaddon, Kibre and Maloghurst.

None wore their helmets and as they turned, he could see that each one had the same air of helpless desperation. He had walked into hell with these warriors time and time again, and seeing his brothers with such expressions on their faces, drained him of his anger, leaving him hollow and heartbroken.

He slowed his march as he came face to face with Aximand.

'What have you done?' he asked. 'Oh my brothers, what have you done?'

'What needed to be done,' said Abaddon, when Aximand didn't answer.

Loken ignored the first captain and said, 'Little Horus? Tell me what you've done.'

'It is as Ezekyle said. We did what had to be done,' said Aximand. 'The Warmaster was dying and Vaddon couldn't save him. So we brought him to the Delphos.'

'The Delphos?' asked Loken.

'It is the name of this place,' said Aximand. 'The Temple of the Serpent Lodge.'

'Temple?' asked Torgaddon. 'Horus, you brought the Warmaster to a fane? Are you mad? The commander would never have agreed to this.'

'Maybe not,' replied Serghar Targost, stepping forward to stand beside Abaddon, 'but by the end he couldn't even speak. He spoke to that damn remembrancer woman for hours on end before he lost consciousness. We had to place him in a stasis field to keep him alive long enough to bring him here.'

'Is Tarik right?' asked Loken. 'Is this a fane?'

'Fane, temple, Delphos, house of healing, call it what you will,' shrugged Targost. 'With the Warmaster on the threshold of death, neither religion nor its denial seems very significant any more. It is the only hope we have left and what do we have to lose? If we do nothing, the Warmaster dies. At least this way he has a chance of life.'

'And at what price will we buy his life?' demanded Loken, 'By bringing him to a house of false gods? The Emperor tells us that civilisation will only achieve perfection when the last stone of the last church falls upon the last priest, and this is where you bring the Warmaster. This goes against everything we have fought for these last two centuries. Don't you see that?'

'If the Emperor was here, he would do the same,' said Targost, and Loken felt his choler rise to the surface at such hubris.

He stepped threateningly close to Targost. 'You think you know the Emperor's will, Serghar? Does being lodge master of a secret society give you the power to know such a thing?'

'Of course not,' sneered Targost, 'but I know he would want his son to live.'

'By entrusting his life to these… savages?'

'It is from these savages that our own quiet order comes,' pointed out Targost.

'Yet another reason for me to distrust it then,' snapped Loken, turning from the lodge master and addressing Vipus and Torgaddon. 'Come on. We're getting the Warmaster out of there.'

'You can't,' said Maloghurst, limping forward to join Abaddon, and Loken had the distinct impression that his brothers were forming a barrier between him and the gateway.

'What do you mean?'

'It is said that once the Delphos Gate is shut, there is no way to open it save from the inside. A man in need of healing is carried inside and left to whatever the eternal spirits of deceased things decree for him. If it is his destiny to live, he may open the gate himself, if not, it opens in nine days and his remains are burned before being cast into the pool.'

'So you've just left the Warmaster inside? For all the good that will do him, you might just as well have left him on the Vengeful Spirit and "eternal spirits of deceased things" - what does that even mean? This is insane. Can't you see that?'

'Standing by and watching him die would have been insane,' said Maloghurst. 'You judge us for acting out of love. Can't you see that?'

'No, Mal, I can't,' replied Loken sadly. 'How did you even think to bring him here anyway? Was it some secret knowledge your damned lodge is privy to?'

None of his brothers spoke, and as Loken searched their faces for answers, the truth of the matter was suddenly, horribly, clear to him.

'Erebus told you of this place, didn't he?'

'Yes,' admitted Targost. 'He knows of these lodges of old and has seen the power of their healing houses. If the Warmaster lives you will be thankful he spoke of it.'

'Where is he?' demanded Loken. 'He will answer to me for this.'

'He is not here, Garvi,' said Aximand. 'This was for the Sons of Horus to do.'

'Then where is he now, still on the Vengeful Spirit?'

Aximand shrugged. 'I suppose so. Why is it important to you?'

'I believe you have all been deceived, my brothers,' said Loken. 'Only the Emperor has the power to heal the Warmaster now. All else is falsehood and the domain of unclean corpse-whisperers.'

'The Emperor is not here,' said Targost bluntly. 'We take what aid we can.'

'What of you, Tarik?' put in Abaddon. 'Will you turn from your Mournival brothers, as Garviel does? Stand with us.'

'Garvi may be a starch-arse, Ezekyle, but he's right and I can't stand with you on this one. I'm sorry,' said Torgaddon as he and Loken turned away from the gate.

'You forget your Mournival oath!' cried Abaddon as they marched away. 'You swore to be true to the Mournival to the end of your lives. You will be oath-breakers!'

The words of the first captain hit Loken with the force of a bolter round and he stopped in his tracks. Oath-breaker… The very idea was hideous, Aximand came after him, grabbing his arm and pointing towards the pool of water. The black water rippled with motion and Loken could see the yellow crescent of Davin's moon wavering in its surface.

'See?' said Aximand. 'The moon shines upon the water, Loken. The crescent mark of the new moon… It was branded upon your helmet when we swore our Mournival oath. It is a good omen, my brother.'

'Omen?' spat Loken, shrugging off his touch. 'Since when have we put our faith in omens, Horus? The Mournival oath was pantomime, but this is ritual. This is sorcery. I told you then that I would not bow to any fane or acknowledge any spirit. I told you that I owned only the empirical clarity of Imperial Truth and I stand by those words.'

'Please, Garvi,' begged Aximand. 'We are doing the right thing.'

Loken shook his head. 'I believe we will all rue the day you brought the Warmaster here.'
