Raid on the Black Sun headquarters

During the Cold War between the Galactic Republic and the reconstituted Sith Empire, the Coruscant Security Force's special tactical unit and a Jedi Knight raided the headquarters of the Black Sun crime syndicate on the Republic capital of Coruscant in order to rescue the scientist Doctor Eli Tarnis. Tarnis, the creator of the Planet Prison superweapon, had been kidnapped by Black Sun and taken to the gang's territory, and the former apprentice of Jedi Master Orgus Din—now a Jedi Knight on an assignment on Coruscant— was sent to rescue the scientist. With the aid of Sergeant Nidaljo and the special tactical unit, the Knight and the astromech droid T7-O1 successfully invaded the gang's headquarters, but instead of finding Tarnis, the Jedi discovered that Tarnis was in fact a Sith Lord. Together, the CSF and the Jedi defeated the Black Sun leader Salarr, and put a major dent in the syndicate's operations, and the Knight returned to the Senate Building determined to hunt down the traitorous Tarnis.
