Viserion

One of the three dragons hatched by Daenerys in the Great Grass Sea. Viserion participated in the Second Conquest, with Daenerys’ urging, but none claimed her as a rider. Along with Drogon, Viserion also took part in the fight against the Others when Aegon and Rhaegal remained in the South. During the years after the conquest Viserion more often than not resided on Dragonstone, and was the first to provide a clutch of eggs. She would not have a rider until Aegon and Daenerys’ grandson, Aenar, then a boy no older than 8, boldly went to claim her. After Aenar's death, his grandson, Daeron Targaryen, followed the beast to Massey's Hook, where he mounted her and became her second rider.
