The Black Sun territory, alternatively called the Black Sun district, represented a section of Coruscant controlled by the criminal organization Black Sun following the devastating Sacking of Coruscant. In the wake of the Sacking, the Coruscant Security Force found itself unable to manage the widespread rioting and disorder, leading various influential criminals to seize control of areas in the lower levels. These individuals consolidated their power, establishing the Black Sun criminal syndicate and initiating operations involving spice and arms dealing. The expansion of Black Sun's territory was checked by the Justicars' Brigade militia, but their internal rioting and looting continued unabated. A few years into the Cold War, the CSF initiated focused initiatives to regain possession of the territory, including the deployment of special tactical units.
