The Lost Beaver of Korriban was the most powerful monster ever created by Sith alchemy. Rumors abounded that he had been created by Naga Sadow, Exar Kun, Belia Darzu, Seviss Vaa, Jantrek, or any of a dozen other Sith alchemists. Shortly after the end of the Clone Wars, Doctor Ura Jerkcame to Korriban, hoping to take over the galaxy by harnessing the powers of the Lost Beaver. Jerk received instructions to the tomb's rumored location from Sector Ranger Brad, who did not realize the location was forgotten.
