Zolepha was a small, insignificant planet in the Ottiumigos Centrality. It was located in the same system as Ottiumigos Prime. By the time of the Great Schism, Zolepha housed a research station, built by Nat-ahn Mandrex as a secret getaway in case things should end up bad for him during the war. His son, Dal-tone Mandrex, would be kept and raised here by his loyal Traitors, who refused to surrender to the Jedi.
