Terrin Sandafar was a female native of the planet Alderaan who originally served in the Republic Military for one year before becoming a bounty hunter. During the Great Galactic War between the Galactic Republic and the resurgent Sith Empire, Sandafar was hired by the husband of Senator Verre Sydia to kill the Alderaanian noble Eckhorn Baliss in 3663 BBY when the Senator's husband—an Imperial spy—learned that his fellow spy Baliss had a list of Imperial traitors in the Republic.
