During the time of the Cold War that existed between the Galactic Republic and the Sith Empire, a Jedi Knight launched an assault on the laboratory belonging to the Sith Lord Sadic. This lab was located far below Shadow Town, within the Imperial prison sector of Nar Shaddaa. Assisted by Agent Galen from the Republic Strategic Information Service, the Jedi Knight was able to overcome Sadic. Sadic had intentionally subjected himself to the Power Guard procedure to amplify his strength. Following the confrontation, the Republic Special Forces's Blackstar Squad commandos, acting under the Jedi's orders, obliterated the lab to ensure the Power Guard Project was terminated along with Sadic.
