Balerion

Balerion, called the Black Dread, was one of the three great dragons of Aegon I Targaryen and his sisters, that were used to conquer much of Westeros during the War of Conquest. Balerion died of old age[1] in 94 AC[2] during the reign of King Jaehaerys I Targaryen, around two hundred years old.[3]
