During the era of the Cold War fought between the Galactic Republic and the Sith Empire, the Sith Lord known as Sadic operated a laboratory. This lab was located within the Imperial prison sector of Shadow Town found on Nar Shaddaa. His work involved the large-scale production of Power Guards at this location. However, his endeavors were cut short by his death when he was killed by a Jedi Knight, after which the commandos of Blackstar Squad used explosives to obliterate the entire facility.
