Yupe Tashu was a male human who served in the Galactic Empire as one of Emperor Sheev Palpatine's closest advisers. Although he could not use the Force himself, Tashu was a historian of the dark side and a Sith cultist. Following the death of the Emperor during the Battle of Endor, Tashu became a part of the Imperial Future Council, a group of high-ranking officials who met on Akiva to decide the future of the shattered Empire. However, Tashu was captured when the fledgling New Republic learned Imperial leaders were flocking to Akiva and attacked.
