"We must fight this war with words before we go to battle," the prince declared. The lords of the Great Houses held the key to victory, Daemon insisted; their bannermen and vassals would follow where they led. Aegon the Usurper had won the allegiance of the Lannisters of Casterly Rock, and Lord Tyrell of Highgarden was a mewling boy in swaddling clothes whose mother, acting as his regent, would most like align the Reach with her overmighty bannermen, the Hightowers… but the rest of the realm's great lords had yet to declare.
"Storm's End will stand with us," Princess Rhaenys declared. She herself was of that blood on her mother's side, and the late Lord Boremund had always been the staunchest of friends.
Prince Daemon had good reason to hope that the Maid of the Vale might bring the Eyrie to their side as well. Aegon would surely seek the support of Pyke, he judged; only the Iron Islands could hope to match the strength of House Velaryon at sea. But the ironmen were notoriously fickle, and Dalton Greyjoy loved blood and battle; he might easily be persuaded to support the princess.
The north was too remote to be of much import in the fight, the council judged; by the time the Starks gathered their banners and marched south, the war might well be over. Which left only the riverlords, a notoriously quarrelsome lot ruled over, in name at least, by House Tully of Riverrun. "We have friends in the riverlands," the prince said, "though not all of them dare show their colors yet. We need a place where they can gather, a toehold on the mainland large enough to house a sizeable host, and strong enough to hold against whatever forces the usurper can send against us." He showed the lords a map. "Here. Harrenhal."
And so it was decided. Prince Daemon would lead the assault on Harrenhal, riding Caraxes. Princess Rhaenyra would remain on Dragonstone until she had recovered her strength. The Velaryon fleet would close off the Gullet, sallying forth from Dragonstone and Driftmark to block all shipping entering or leaving Black water Bay. "We do not have the strength to take King's Landing by storm," Prince Daemon said, "no more than our foes could hope to capture Dragonstone. But Aegon is a green boy, and green boys are easily provoked.
Mayhaps we can goad him into a rash attack." The Sea Snake would command the fleet, whilst Princess Rhaenys flew overhead to keep their foes from attacking their ships with dragons. Meanwhile, ravens would go forth to Riverrun, the Eyrie, Pyke, and Storm's End, to gain the allegiance of their lords.
Then up spoke the queen's eldest son, Jacaerys. "We should bear those messages," he said. "Dragons will win the lords over quicker than ravens." His brother Lucerys agreed, insisting that he and Jace were men, or near enough to make no matter. "Our uncle calls us Strongs, and claims that we are bastards, but when the lords see us on dragonback they will know that for a lie. Only Targaryens ride dragons." Even young Joffrey chimed in, offering to mount his own dragon Tyraxes and join his brothers.
Princess Rhaenyra forbade that; Joff was but twelve. But Jacaerys was fifteen, Lucerys fourteen; strong and strapping lads, skilled in arms, who had long served as squires. "If you go, you go as messengers, not as knights," she told them. "You must take no pan in any fighting." Not until both boys had sworn solemn oaths upon a copy of The Seven-Pointed Star would Her Grace consent to using them as her envoys. It was decided that Jace, being the older of the two, would take the longer, more dangerous task, flying first to the Eyrie to treat with the Lady of the Vale, then to White Harbor to win over Lord Manderly, and lastly to Winterfell to meet with Lord Stark. Luke's mission would be shorter and safer; he was to fly to Storm's End, where it was expected that Borros Baratheon would give him a warm welcome.
A hasty coronation was held the next day. The arrival of Ser Steffon Darklyn, late of Aegon's Kingsguard, was an occasion of much joy on Dragonstone, especially when it was learned that he and his fellow loyalists ("turncloaks," Ser Otto would name them, when offering a reward for their capture) had brought the stolen crown of King Jaehaerys the Conciliator. Three hundred sets of eyes looked on as Prince Daemon Targaryen placed the Old King's crown on the head of his wife, proclaiming her Rhaenyra of House Targaryen, First of Her Name, Queen of the Andals, the Rhoynar, and the First Men. The prince claimed for himself the style Protector of the Realm, and Rhaenyra named her eldest son, Jacaerys, the Prince of Dragonstone and heir to the Iron Throne.
Her first act as queen was to declare Ser Otto Hightower and Queen Alicent traitors and rebels. "As for my half brothers, and my sweet sister Helaena," she announced, "they have been led astray by the counsel of evil men. Let them come to Dragonstone, bend the knee, and ask my forgiveness, and I shall gladly spare their lives and take them back into my heart, for they are of my own blood, and no man or woman is as accursed as the kinslayer."
Word of Rhaenyra's coronation reached the Red Keep the next day, to the great displeasure of Aegon II. "My half sister and my uncle are guilty of high treason," the young king declared. "I want them attainted, I want them arrested, and I want them dead."
Cooler heads on the green council wished to parlay. "The princess must be made to see that her cause is hopeless," Grand Maester Orwyle said. "Brother should not war against sister. Send me to her, that we may talk and reach an amicable accord."
Aegon would not hear of it. Septon Eustace tells us that His Grace accused the grand maester of disloyalty and spoke of having him thrown into a black cell "with your black friends." But when the two queens — his mother Queen Alicent and his wife Queen Helaena — spoke in favor of Orwyle's proposal, the king gave way reluctantly. So Grand Maester Orwyle was dispatched across Blackwater Bay under a peace banner, leading a retinue that included Ser Arryk Cargyll of the Kingsguard and Ser Gwayne Hightower of the gold cloaks, along with a score of scribes and septons.
The terms offered by the king were generous. If the princess would acknowledge him as king and make obeisance before the Iron Throne, Aegon II would confirm her in her possession of Dragonstone, and allow the island and castle to pass to her son Jacaerys upon her death. Her second son, Lucerys, would be recognized as the rightful heir to Driftmark, and the lands and holdings of House Velaryon; her boys by Prince Daemon, Aegon the Younger and Viserys, would be given places of honor at court, the former as the king's squire, the latter as his cupbearer. Pardons would be granted to those lords and knights who had conspired treasonously with her against their true king.
Rhaenyra heard these terms in stony silence, then asked Orwyle if he remembered her father, King Viserys. "Of course, Your Grace," the maester answered. "Perhaps you can tell us who he named as his heir and successor," the queen said, her crown upon her head. "You, Your Grace," Orwyle replied. And Rhaenyra nodded and said, "With your own tongue you admit I am your lawful queen. Why then do you serve my half brother, the pretender? Tell my half brother that I will have my throne, or I will have his head," she said, sending the envoys on their way.
