Rhaenyra is the first-born child of Viserys and his first wife Aemma Arryn. As such, she has a legitimate claim to the throne, but the age-old issue of her being a woman raises its ugly head. Her uncle and the younger brother to King Viserys, Daemon, is the presumed heir; but Viserys names Rhaenyra his heir instead, citing Aegon’s dream of A Song of Ice and Fire.
As an adult, Rhaenyra marries Laenor Velaryon and welcomes three children—Jacerys, Lucerys, and Joffrey—with him, but they are assumed to be fathered by Harwin Strong. After Laenor’s “death,” she marries her uncle Daemon. According to Firey & Blood, they have three children together: Viserys II, Aegon II, and Visenya. When her half-brother Aegon II usurps the throne, Rhaenyra is crowned queen in a separate ceremony on Dragonstone.
