Gerr was a male Human Acolyte who attended the Sith Academy on Korriban during the Cold War between the reconstituted Sith Empire and the Galactic Republic. He was present in Harkun's chamber in 3643 BBY when he was called forth by the Overseer. As he complied, Harkun ordered Ffon Althe to kill him. Gerr tried to escape, but Ffon released a bolt of Force lightning and killed the acolyte.
