Doctor Zelka Forn's medical practice was situated on the Outer Rim world of Taris. This clinic was established and operated by Zelka Forn, a Doctor and a loyal supporter of the Republic. His establishment welcomed individuals from all walks of life, irrespective of their species, gender, social standing, or military position. The clinic featured a primary area equipped with three beds and three kolto tanks. Additionally, it contained a concealed chamber housing several kolto tanks, where Zelka covertly sustained Republic troops for as long as he could. If the Sith were to discover this clandestine operation, the clinic would face immediate closure; consequently, the room remained securely locked, and only Revan became aware of its existence. Zelka was also assisted by a medical droid and a human assistant named Gurney, who was secretly employed by the Exchange.
Subsequently, Revan delivered a small quantity of antidote to Forn, intended to combat Taris's devastating Rakghoul plague. Utilizing this sample, Forn successfully produced a larger supply of the antidote, which he then made available to the general population at an affordable cost. Forn attempted to compensate Revan for their help, but Revan declined the offer.
