Ashli Tar-sonis was a Human female and the daughter of two former Yanibar Guardsmen, Vree and Storia Tar-sonis. She was born in 5 ABY and raised on Yanibar. Her parents tended to isolate themselves from others, moving to the remote steppes north of Cadthak and making a living from ranching. Ashli grew up on their ranch, but longed for the excitement and social scene of a larger city, which led to her persuading her parents to let her attend secondary school in Union City.
