Rhaenyra Targaryen was a key figure in the history of the Targaryen dynasty in Westeros, known for her claim to the Iron Throne during the Dance of the Dragons, a civil war between rival factions of the Targaryen family. Born as the firstborn child of King Viserys I Targaryen, she was a dragonrider, bonded with her dragon Syrax, and was a strong advocate for her right to rule. Rhaenyra's struggle for power was marked by political intrigue and betrayal, as she faced opposition from her half-brother Aegon II Targaryen, who also claimed the throne. Her story is a significant part of the lore in George R.R. Martin's works, particularly in the book Fire & Blood, which details the history of the Targaryens.
