Sunsbringer served as a corporal within the Alliance to Restore the Republic's military forces. Her post was at Echo Base, specifically in the command center. In conjunction with Toryn Farr, she participated in a wager concerning the potential romance between Han Solo and Leia Organa; when Solo declared his plan to depart, Sunsbringer's attention strayed from her monitoring duties, and she proposed that someone tail them to observe their actions. In the course of the Battle of Hoth, Sunsbringer sustained several injuries.
