Prince Jacaerys needed more dragonriders, and more dragons, and it was to those born of dragonseed that he turned, vowing that any man who could master a dragon would be granted lands and riches and dubbed a knight. His sons would be ennobled, his daughters wed to lords, and he himself would have the honor of fighting beside the Prince of Dragonstone against the pretender Aegon II Targaryen and his treasonous supporters.
Not all those who came forward in answer to the prince's call were seeds, nor even the sons or grandsons of seeds. A score of the queen's own household knights offered themselves as dragonriders, amongst them the Lord Commander of her Kingsguard, Ser Steffon Darklyn, along with squires, scullions, sailors, men-at-arms, mummers, and two maids.
Dragons are not horses. They do not easily accept men upon their backs, and when angered or threatened, they attack. Sixteen men lost their lives during an attempt to become dragonriders. Three times that number were burned or maimed. Steffon Darklyn was burned to death whilst attempting to mount the dragon Seasmoke. Lord Gormon Massey suffered the same fate when approaching Vermithor. A man called Silver Denys, whose hair and eyes lent credence to his claim to be a bastard son of King Maegor the Cruel, had an arm torn off by Sheepstealer. As his sons struggled to staunch the wound, the Cannibal descended on them, drove off Sheepstealer, and devoured father and sons alike.
Yet Seasmoke, Vermithor, and Silverwing were accustomed to men and tolerant of their presence. Having once been ridden, they were more accepting of new riders. Vermithor, the Old King's own dragon, bent his neck to a blacksmith's bastard, a towering man called Hugh the Hammer or Hard Hugh, whilst a pale-haired man-at-arms named Ulf the White (for his hair) or Ulf the Sot (for his drinking) mounted Silverwing, beloved of Good Queen Alysanne.
And Seasmoke, who had once borne Laenor Velaryon, took onto his back a boy of ten-and-five known as Addam of Hull, whose origins remain a matter of dispute amongst historians to this day. Not long after Addam of Hull had proved himself by flying Seasmoke, Lord Corlys went so far as to petition Queen Rhaenyra to remove the taint of bastardy from him and his brother. When Prince Jacaerys added his voice to the request, the queen complied. Addam of Hull, dragonseed and bastard, became Addam Velaryon, heir to Driftmark.
Dragonstone's three wild dragons were less easily claimed than those that had known previous riders, yet attempts were made upon them all the same. Sheepstealer, a notably ugly "mud brown" dragon hatched when the Old King was still young, had a taste for mutton, swooping down on shepherd's flocks from Driftmark to the Wendwater. He seldom harmed the shepherds, unless they attempted to interfere with him, but had been known to devour the occasional sheepdog. Grey Ghost dwelt in a smoking vent high on the eastern side of the Dragonmont, preferred fish, and was most oft glimpsed flying low over the narrow sea, snatching prey from the waters. A pale grey-white beast the color of morning mist, he was a notably shy dragon who avoided men and their works for years at a time.
The largest and oldest of the wild dragons was the Cannibal, so named because he had been known to feed on the carcasses of dead dragons, and descend upon the hatcheries of Dragonstone to gorge himself on newborn hatchlings and eggs. Would-be dragontamers had made attempts to ride him a dozen times; his lair was littered with their bones.
None of the dragonseeds were fool enough to disturb the Cannibal (any who were did not return to tell their tales). Some sought the Grey Ghost, but could not find him, for he was ever an elusive creature. Sheepstealer proved easier to flush out, but he remained a vicious, ill-tempered beast, who killed more seeds than the three "castle dragons" together. One who hoped to tame him (after his quest for Grey Ghost proved fruitless) was Alyn of Hull. Sheepstealer would have none of him. When he stumbled from the dragon's lair with his cloak aflame, only his brother's swift action saved his life. Seasmoke drove the wild dragon off as Ad-dam used his own cloak to beat out the flames. Alyn Velaryon would carry the scars of the encounter on his back and legs for the rest of his long life. Yet he counted himself fortunate, for he lived. Many of the other seeds and seekers who aspired to ride upon Sheepstealer's back ended in Sheepstealer's belly instead.
In the end, the brown dragon was brought to heel by the cunning and persistence of a "small brown girl" of six-and-ten, named Netty, who delivered him a freshly slaughtered sheep every morning, until Sheepstealer learned to accept and expect her. She was black-haired, brown-eyed, brown-skinned, skinny, foul-mouthed, filthy, and fearless… and the first and last rider of the dragon Sheepstealer.
Thus did Prince Jacaerys achieve his goal. For all the death and pain it caused, the widows left behind, the burned men who would carry their scars until the day they died, four new dragonriders had been found. As 129 AC drew to a close, the prince prepared to fly against King's Landing. The date he chose for the attack was the first full moon of the new year.
