Shrykos was a young she-dragon hatched from the egg placed in the cradle of Prince Jaehaerys, eldest son of Aegon II and Helaena, and bound to him, though he was murdered at six and she was never ridden. The books do not describe her; the illustration of the Dragonpit in The Rise of the Dragon makes her coppery.
She was chained in the Dragonpit when the Shepherd's mob broke in during 130 AC, and killed scores of them before she died. Her slayer was a woodsman called Hobb the Hewer, who leapt onto her neck as she roared and twisted, locked his legs about her, and brought his axe down seven times, crying the name of one of the Seven with each blow; it was the Stranger's blow that broke through scale and bone into her skull.
