Lyanna Stark was the only daughter of Lord Rickard Stark and his wife, Lady Lyarra Stark. She had two older brothers, Brandon and Eddard, and one younger brother, Benjen. Her abduction by Prince Rhaegar Targaryen ultimately triggered Robert's Rebellion and led to the downfall of the Targaryen dynasty.

PS- I am working on another Character. The hint is "Ocarina"
