Rhaenyra Targaryen is the eldest child of Viserys I Targaryen and the only surviving child of his first wife, Aemma Arryn. When she was a child, her father broke tradition and named Rhaenyra his heir and the future queen of Westeros in place of her brother, Aegon Targaryen. This infuriated her step-mother, Alicent Hightower, and started a feud between the two halves of the Targaryen Dynasty which led to the Dance of the Dragons. Like many in her family, Rhaenyra practices polygamy: she is married to both Laenor Velaryon and Aemon Targaryen. They are the fathers of her seven children. Ser Harwin Strong is Rhaenyra's sworn sword after her spurning of Criston Cole. The two are also lovers, though Rhaenyra has been sure to prevent him fathering any of her children with moon tea. Rhaenyra is a dragonrider who rides the dragon Syrax into battle.
