At some point Kurak became a Sith Juggernaut, and led raids upon many an Old Republic outpost. Darth Malgus was more distinguished among the Sith and the Jedi, and that was the primary cause for Kurak's anger during much of the Great Galactic War. During the Cold War, Kurak continued to act relatively behind the scenes. His Master, Darth Eskatos, was the most powerful Sith Sorceror ever; he managed to trap Kurak in a time stasis field, along with one of Kurak's apprentices. The stasis field was supposed to turn off every 200 years to allow Kurak to scout out into the world; however, the apprentice escaped the stasis and disabled it, effectively freezing Kurak in time for almost 3,000 years.
