Kisadran was a scientist employed by the Czerka Corporation at their CZ-198 research facility, where Doctor Kisadran worked on the Vigilant security system—a genetically-modified Flesh Raider integrated with the electronic security of the facility. Kisadran recorded a log of the experiment's results, and after the Vigilant killed two technicians and three janitors, Special Executive Rasmus Blys suggested to Kisadran that Doctor Teak be assigned to interacting with the Vigilant, as Teak was considered expendable.
