Eisek was a Human commander of the male gender. He served in the reconstituted Sith Empire's navy. During the concluding year of the Cold War, he commanded the Harrower-class dreadnaught named Valor Prevails, which was assigned to patrol the Vesla system. Eisek captured Theron Shan, a SIS agent, along with his comrades. Subsequently, Eisek tried to negotiate with Theron Shan concerning the Empire's advanced super weapons designs. Although Theron agreed to the proposition, he rendered Eisek unconscious and imprisoned him. Shortly after, Darth Mekhis assassinated him as punishment for his treachery.
