Darkside represented a region of the planet Coruscant, specifically situated within the Coruscant underworld.
While Darkside existed one kilometer below the higher regions of Coruscant, its position was between three and four kilometers above the planet's actual surface. Its structure included four distinct areas: the Industrial Sector, the Recycling Sector, the Residential Sector, and the Services Sector.
During 19 BBY, the Dark Jedi known as Garth Ezzar journeyed to Darkside after the destruction of the Almas Academy. The Heroes of Cularin pursued him there, ultimately engaging him in combat and achieving victory.
