Rhaegar Targaryen was the eldest son and heir of King Aerys II, a skilled warrior, and a musician known for his melancholy nature, who secretly married Lyanna Stark, sparking Robert's Rebellion and fathering Jon Snow. He was the older brother of Daenerys and Viserys, and was married to Elia Martell, with whom he had two children, Rhaenys and Aegon. His obsession with a prophecy led him to elope with Lyanna, a controversial act that ultimately led to his death at the hands of Robert Baratheon.
