No king in Westeros was more feared than Black Harren, whose cruelty had become legendary all through the Seven Kingdoms. And no king in Westeros felt more threatened than Argilac the Storm King, last of the Durrandon, an aging warrior whose only heir was his maiden daughter. Thus it was that King Argilac reached out to the Targaryens on Dragonstone, offering Lord Aegon his daughter in marriage, with all the lands east of the Gods Eye from the Trident to the Blackwater Rush as her dowry.

Aegon Targaryen spurned the Storm King’s proposal. He had two wives, he pointed out; he did not need a third. And the dower lands being offered had belonged to Harrenhal for more than a generation. They were not Argilac’s to give. Plainly, the aging Storm King meant to establish the Targaryens along the Blackwater as a buffer between his own lands and those of Harren the Black.

   The Lord of Dragonstone countered with an offer of his own. He would take the dower lands being offered if Argilac would also cede Massey’s Hook and the woods and plains from the Blackwater south to the river Wendwater and the headwaters of the Mander. The pact would be sealed by the marriage of Argilac’s daughter to Orys Baratheon, Lord Aegon’s childhood friend and champion.

These terms Argilac the Arrogant rejected angrily. Orys Baratheon was a baseborn half-brother to Lord Aegon, it was whispered, and the Storm King would not dishonor his daughter by giving her hand to a bastard. The very suggestion enraged him. Argilac had the hands of Aegon’s envoy cut off and returned to him in a box. “These are the only hands your bastard shall have of me,” he wrote.

Aegon made no reply. Instead he summoned his friends, bannermen, and principal allies to attend him on Dragonstone. Their numbers were small. The Velaryons of Driftmark were sworn to House Targaryen, as were the Celtigars of Claw Isle. From Massey’s Hook came Lord Bar Emmon of Sharp Point and Lord Massey of Stonedance, both sworn to Storm’s End, but with closer ties to Dragonstone. Lord Aegon and his sisters took counsel with them, and visited the castle sept to pray to the Seven of Westeros as well, though he had never before been accounted a pious man.

On the seventh day, a cloud of ravens burst from the towers of Dragonstone to bring Lord Aegon’s word to the Seven Kingdoms of Westeros. To the seven kings they flew, to the Citadel of Oldtown, to lords both great and small. All carried the same message: from this day forth there would be but one king in Westeros. Those who bent the knee to Aegon of House Targaryen would keep their lands and titles. Those who took up arms against him would be thrown down, humbled, and destroyed.

Accounts differ on how many swords set sail from Dragonstone with Aegon and his sisters. Some say three thousand; others number them only in the hundreds. This modest Targaryen host put ashore at the mouth of the Blackwater Rush, on the northern bank where three wooded hills rose above a small fishing village.

   In the days of the Hundred Kingdoms, many petty kings had claimed dominion over the river mouth, amongst them the Darklyn kings of Duskendale, the Masseys of Stonedance, and the river kings of old, be they Mudds, Fishers, Brackens, Blackwoods, or Hooks. Towers and forts had crowned the three hills at various times, only to be thrown down in one war or another. Now only broken stones and overgrown ruins remained to welcome the Targaryens. Though claimed by both Storm’s End and Harrenhal, the river mouth was undefended, and the closest castles were held by lesser lords of no great power or military prowess, and lords moreover who had little reason to love their nominal overlord, Harren the Black.

Aegon Targaryen quickly threw up a log-and-earth palisade around the highest of the three hills, and dispatched his sisters to secure the submission of the nearest castles. Rosby yielded to Rhaenys and golden-eyed Meraxes without a fight. At Stokeworth a few crossbowmen loosed bolts at Visenya, until Vhagar’s flames set the roofs of the castle keep ablaze. Then they too submitted.

The Conquerors’ first true test came from Lord Darklyn of Duskendale and Lord Mooton of Maidenpool, who joined their power and marched south with three thousand men to drive the invaders back into the sea. Aegon sent Orys Baratheon out to attack them on the march, whilst he descended on them from above with the Black Dread. Both lords were slain in the one-sided battle that followed; Darklyn’s son and Mooton’s brother thereafter yielded up their castles and swore their swords to House Targaryen. At that time Duskendale was the principal Westerosi port on the narrow sea, and had grown fat and wealthy from the trade that passed through its harbor. Visenya Targaryen did not allow the town to be sacked, but she did not hesitate to claim its riches, greatly swelling the coffers of the Conquerors.

This perhaps would be an apt place to discuss the differing characters of Aegon Targaryen and his sisters and queens.

Visenya, eldest of the three siblings, was as much a warrior as Aegon himself, as comfortable in ringmail as in silk. She carried the Valyrian longsword Dark Sister, and was skilled in its use, having trained beside her brother since childhood. Though possessed of the silver-gold hair and purple eyes of Valyria, hers was a harsh, austere beauty. Even those who loved her best found Visenya stern, serious, and unforgiving; some said that she played with poisons and dabbled in dark sorceries.

   Rhaenys, youngest of the three Targaryens, was all her sister was not, playful, curious, impulsive, given to flights of fancy. No true warrior, Rhaenys loved music, dancing, and poetry, and supported many a singer, mummer, and puppeteer. Yet it was said that Rhaenys spent more time on dragonback than her brother and sister combined, for above all things she loved to fly. She once was heard to say that before she died she meant to fly Meraxes across the Sunset Sea to see what lay upon its western shores. Whilst no one ever questioned Visenya’s fidelity to her brother-husband, Rhaenys surrounded herself with comely young men, and (it was whispered) even entertained some in her bedchambers on the nights when Aegon was with her elder sister. Yet despite these rumors, observers at court could not fail to note that the king spent ten nights with Rhaenys for every night with Visenya.

Aegon Targaryen himself, strangely, was as much an enigma to his contemporaries as to us. Armed with the Valyrian steel blade Blackfyre, he was counted amongst the greatest warriors of his age, yet he took no pleasure in feats of arms, and never rode in tourney or melee. His mount was Balerion the Black Dread, but he flew only to battle or to travel swiftly across land and sea. His commanding presence drew men to his banners, yet he had no close friends, save Orys Baratheon, the companion of his youth. Women were drawn to him, but Aegon remained ever faithful to his sisters. As king, he put great trust in his small council and his sisters, leaving much of the day-to-day governance of the realm to them…yet did not hesitate to take command when he found it necessary. Though he dealt harshly with rebels and traitors, he was open-handed with former foes who bent the knee.

This he showed for the first time at the Aegonfort, the crude wood-and-earth castle he had raised atop what would henceforth and forever be known as Aegon’s High Hill. Having taken a dozen castles and secured the mouth of the Blackwater Rush on both sides of the river, he commanded the lords he had defeated to attend him. There they laid their swords at his feet, and Aegon raised them up and confirmed them in their lands and titles. To his oldest supporters he gave new honors. Daemon Velaryon, Lord of the Tides, was made master of ships, in command of the royal fleet. Triston Massey, Lord of Stonedance, was named master of laws, Crispian Celtigar master of coin. And Orys Baratheon he proclaimed to be “my shield, my stalwart, my strong right hand.” Thus Baratheon is reckoned by the maesters the first King’s Hand.
