Aelyx Targaryen was a member of House Targaryen before the War of Conquest.
History[]
Aelyx was born at Dragonstone, the firstborn son of Lord Aerys Targaryen. He was the brother of Baelon and Daemion Targaryen, both of whom ruled as Lords of Dragonstone. Aelyx presumably died before his father, as there are no records of Aelyx ever having ruled over the island.
