Viserys I Targaryen is the current king of Westeros at the start of Dancing Dragons. He has two wives, Aemma Arryn and Alicent Hightower, and a multitude of children. Unlike previous kings of Westeros, Viserys broke with tradition and named his daughter Rhaenyra Targaryen his heir over his son Aegon Targaryen. This led to the splitting of his family and the civil war known as the Dance of the Dragons. He is a dragonrider for the dragon Urrax whom he hatched from an egg when he was young.
