Viserys I succeeds to the throne after the death of his grandfather Jaehaerys I. Although he himself is a popular, generous king with a relatively peaceful and prosperous reign, his decisions lead to the civil war that would weaken the Targaryen dynasty permanently. His first marriage produces only one surviving child, Princess Rhaenyra, who he proclaims as his heir, even after a second marriage results in sons.
Viserys dies in his sleep at the age of 52. After his death, his second wife, Alicent, and her sons scheme to keep Rhaenyra off the throne, leading to a deadly civil war known as the Dance of the Dragons.
