Yima, a lieutenant, served as a female official within the Telos Security Force in the aftermath of the Jedi Civil War. She was tasked by Dol Grenn with the investigation of the Batu Rem impostor's TSF infiltration.
Within the deleted content of Knights of the Old Republic II, it was planned that the Jedi Exile would encounter Lieutenant Yima. Yima's role would have been to provide the Exile with a mission: to reveal Lieutenant Atallo, a TSF officer engaged in corruption who was in charge of the Czerka Corporation hangar bay. The dialogue associated with this implies Yima held the position of senior dock officer within the specific hangar bay where the Ebon Hawk made its landing.
