By the time of the Galactic Civil War, the city itself had long been vacated. Directly underneath the abandoned city was a massive abandoned Sewage Complex, consisting of rusting sludge-soaked durasteel girder tunnels and passageways that made up the subterranean sewer system. The seemingly impossible to navigate and endless corridors were patrolled by starved dianogas.
Kyle Katarn ventured into the Sewage Complex underneath the city in order to locate the weapons designer MoffRebus.
