Medechas, a Sith Lord of the reconstituted Sith Empire during the Galactic War, was a Human male. In the course of the invasion of Belsavis, Medechas commanded Special Operations Group Five, with their mission being to secure the Imperial base located at the Imperial Lodgement and to instigate disruption within the Minimum Security Section. In the initial phases of the conflict, Medechas's troops engaged in combat with Republic security forces, who were under the command of Marshall Ellis Ruger.
Lord Medechas is featured on Belsavis in the video game Star Wars: The Old Republic, acting as a central figure in the primary Imperial narrative arc set within the Minimum Security Section.
