And behind the mountain dwelled three wild dragons, never claimed nor ridden by any man, living or dead. The smallfolk had named them Sheepstealer, Grey Ghost, and the Cannibal.

A man called Silver Denys, whose hair and eyes lent credence to his claim to be descended from a bastard son of 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.

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 sheep dog.

Sheepstealer proved easier to flush out, but he remained a vicious, ill-tempered beast, who killed more seeds than the three castle dragons together.

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, who delivered him a freshly slaughtered sheep every morning, until Sheepstealer learned to accept and expect her. Munkun sets down the name of this unlikely dragonrider as Nettles. Mushroom tells us the girl was a bastard of uncertain birth called Netty, born to a dockside whore. By any name, she was black-haired, brown-eyed, brown-skinned, skinny, foul-mouthed, fearless…and the first and last rider of the dragon Sheepstealer.

- Fire and Blood "The Dying of the Dragons: The Red Dragon and the Gold"

It is one thing to face a dragon, another to face five. As Silverwing, Sheepstealer, Seasmoke, and Vermithor descended upon them, the men of the Triarchy felt their courage desert them. The line of warships shattered, as one galley after another turned away. The dragons fell like thunderbolts, spitting balls of fire, blue and orange, red and gold, each brighter than the next. Ship after ship burst asunder or was consumed by flames. Screaming men leapt into the sea, shrouded in fire. Tall columns of black smoke rose up from the water. All seemed lost…all was lost…
