Jareth Sartoris was one of the main protagonists of the novel Star Wars: Death Troopers. He was a captain aboard the imperial prison barge "Purge".

Bio
Captain Sartoris was a cold-blooded officer aboard the Imperial Prison Barge Purge. When the thrusters broke down aboard the Purge, he was part of a salvage team sent to check out a derelict Star Destroyer, the Vector. The team returned with the parts needed to repair the ship, but they inadvertently brought with them the airborne strain of a horrible disease, to which Sartoris had an immunity.

Sartoris attempted to abandon ship via an escape pod, leaving the other survivors to die, but was pulled in by the star destroyer's tractor beam. While aboard the vector, Sartoris was bitten. Knowing his time was short, he sacrificed himself to save the other survivors.
