Politician, spy and coordinator, Ceth began his tenure with the Rebellion shortly after the destruction of Alderaan. Arriving a few minutes after the world's doom, Ceth never forgot the sight of the ruined planet. Swearing an oath of vengeance for the other members of his delegation, Ceth would quickly distinguish himself as an agent of the Rebel Alliance.

With the discovery of the Imperial super-weapon, the Eclipse, Ceth would be put about the task of finding the ship and establishing a series of contacts with which to bring about its destruction.

Eventually successful in the task, Ceth would go on to retire after the war, his oath fulfilled.
