Dragons' name

Daenerys' dragons are named Drogon, Rhaegal and Viserion. Each one is named after someone she has lost in her life: Drogon, the largest dragon with black/red scales, is named after her husband Khal Drogo; Rhaegal, who has green/bronze scales, is named after Daenerys' brother Rhaegar Targaryen, who was killed by Robert Baratheon during Robert's Rebellion; Viserion, the cream/gold scaled dragon, is named after Daenerys' abusive brother Viserys. She claimed that she named her dragon this because "Viserys was cruel and weak and frightened, yet he was my brother still. My dragon will do what he could not."
