Stone does not burn, Harren had boasted, but his castle was not made of stone alone. Wood and wool, hemp and straw, bread and salted beef and grain, all took fire. Nor were Harren’s ironmen made of stone. Smoking, screaming, shrouded in flames, they ran across the yards and tumbled from the wallwalks to die upon the ground below. And even stone will crack and melt if a fire is hot enough. The riverlords outside the castle walls said later that the towers of Harrenhal glowed red against the night, like five great candles…and like candles, they began to twist and melt as runnels of molten stone ran down their sides.

Harren and his last sons died in the fires that engulfed his monstrous fortress that night. House Hoare died with him, and so too did the Iron Islands’ hold on the riverlands. The next day, outside the smoking ruins of Harrenhal, King Aegon accepted an oath of fealty from Edmyn Tully, Lord of Riverrun, and named him Lord Paramount of the Trident. The other riverlords did homage as well, to Aegon as king and to Edmyn Tully as their liege lord. When the ashes had cooled enough to allow men to enter the castle safely, the swords of the fallen, many shattered or melted or twisted into ribbons of steel by dragonfire, were gathered up and sent back to the Aegonfort in wagons.

   South and east, the Storm King’s bannermen proved considerably more loyal than King Harren’s. Argilac the Arrogant gathered a great host about him at Storm’s End. The seat of the Durrandons was a mighty fastness, its great curtain wall even thicker than the walls of Harrenhal. It too was thought to be impregnable to assault. Word of King Harren’s end soon reached the ears of his old enemy King Argilac, however. Lords Fell and Buckler, falling back before the approaching host (Lord Errol had been killed), had sent him word of Queen Rhaenys and her dragon. The old warrior king roared that he did not intend to die as Harren had, cooked inside his own castle like a suckling pig with an apple in his mouth. No stranger to battle, he would decide his own fate, sword in hand. So Argilac the Arrogant rode forth from Storm’s End one last time, to meet his foes in the open field.

The Storm King’s approach was no surprise to Orys Baratheon and his men; Queen Rhaenys, flying Meraxes, had witnessed Argilac’s departure from Storm’s End and was able to give the Hand a full accounting of the enemy’s numbers and dispositions. Orys took up a strong position on the hills south of Bronzegate, and dug in there on the high ground to await the coming of the stormlanders.

As the armies came together, the stormlands proved true to their name. A steady rain began to fall that morning, and by midday it had turned into a howling gale. King Argilac’s lords bannermen urged him to delay his attack until the next day, in hopes the rain would pass, but the Storm King outnumbered the Conquerors almost two to one, and had almost four times as many knights and heavy horses. The sight of the Targaryen banners flapping sodden above his own hills enraged him, and the battle-seasoned old warrior did not fail to note that the rain was blowing from the south, into the faces of the Targaryen men on their hills. So Argilac the Arrogant gave the command to attack, and the battle known to history as the Last Storm began.

The fighting lasted well into the night, a bloody business and far less one-sided than Aegon’s conquest of Harrenhal. Thrice Argilac the Arrogant led his knights against the Baratheon positions, but the slopes were steep and the rains had turned the ground soft and muddy, so the warhorses struggled and foundered, and the charges lost all cohesion and momentum. The stormlanders fared better when they sent their spearmen up the hills on foot. Blinded by the rain, the invaders did not see them climbing until it was too late, and the wet bowstrings of the archers made their bows useless. One hill fell, and then another, and the fourth and final charge of the Storm King and his knights broke through the Baratheon center…only to come upon Queen Rhaenys and Meraxes. Even on the ground, the dragon proved formidable. Dickon Morrigen and the Bastard of Blackhaven, commanding the vanguard, were engulfed in dragonflame, along with the knights of King Argilac’s personal guard. The warhorses panicked and fled in terror, crashing into riders behind them, and turning the charge into chaos. The Storm King himself was thrown from his saddle.

   Yet still Argilac continued to battle. When Orys Baratheon came down the muddy hill with his own men, he found the old king holding off half a dozen men, with as many corpses at his feet. “Stand aside,” Baratheon commanded. He dismounted, so as to meet the king on equal footing, and offered the Storm King one last chance to yield. Argilac cursed him instead. And so they fought, the old warrior king with his streaming white hair and Aegon’s fierce, black-bearded Hand. Each man took a wound from the other, it was said, but in the end the last of the Durrandon got his wish, and died with a sword in his hand and a curse on his lips. The death of their king took all heart out of the stormlanders, and as the word spread that Argilac had fallen, his lords and knights threw down their swords and fled.

For a few days it was feared that Storm’s End might suffer the same fate as Harrenhal, for Argilac’s daughter Argella barred her gates at the approach of Orys Baratheon and the Targaryen host, and declared herself the Storm Queen. Rather than bend the knee, the defenders of Storm’s End would die to the last man, she promised when Queen Rhaenys flew Meraxes into the castle to parley. “You may take my castle, but you will win only bones and blood and ashes,” she announced…but the soldiers of the garrison proved less eager to die. That night they raised a peace banner, threw open the castle gate, and delivered Lady Argella gagged, chained, and naked to the camp of Orys Baratheon.

   It is said that Baratheon unchained her with his own hands, wrapped his cloak around her, poured her wine, and spoke to her gently, telling her of her father’s courage and the manner of his death. And afterward, to honor the fallen king, he took the arms and words of the Durrandon for his own. The crowned stag became his sigil, Storm’s End became his seat, and Lady Argella his wife.

With both the riverlands and stormlands now under the control of Aegon the Dragon and his allies, the remaining kings of Westeros saw plainly that their own turns were coming. At Winterfell, King Torrhen called his banners; given the vast distances in the North, he knew that assembling an army would take time. Queen Sharra of the Vale, regent for her son Ronnel, took refuge in the Eyrie, looked to her defenses, and sent an army to the Bloody Gate, gateway to the Vale of Arryn. In her youth Queen Sharra had been lauded as “the Flower of the Mountain,” the fairest maid in all the Seven Kingdoms. Perhaps hoping to sway Aegon with her beauty, she sent him a portrait and offered herself to him in marriage, provided he named her son Ronnel as his heir. Though the portrait did finally reach him, it is not known whether Aegon Targaryen ever replied to her proposal; he had two queens already, and Sharra Arryn was by then a faded flower, ten years his elder.

Meanwhile, the two great western kings had made common cause and assembled their own armies, intent on putting an end to Aegon for good and all. From Highgarden marched Mern IX of House Gardener, King of the Reach, with a mighty host. Beneath the walls of Castle Goldengrove, seat of House Rowan, he met Loren I Lannister, King of the Rock, leading his own host down from the westerlands. Together the Two Kings commanded the mightiest host ever seen in Westeros: an army fifty-five thousand strong, including some six hundred lords great and small and more than five thousand mounted knights. “Our iron fist,” boasted King Mern. His four sons rode beside him, and both of his young grandsons attended him as squires.
