Senn Cholus served as an officer within the Imperial forces before ultimately switching his allegiance to the Rebel Alliance.
Born into a wealthy family on Pencael IV, Senn Cholus enjoyed a close relationship with his sister, Aven. During their formative years, they both underwent pilot training. The Cholus family intended for both siblings to enroll in the Imperial Academy.
Aven, however, opposed Imperial beliefs and abandoned her family to enlist with the Rebel Alliance. Senn, unlike his sister, did not share these reservations and chose to join the Empire.
He rose through the ranks to become a highly respected commander within the Imperial Navy.
