The Great Hunt was a series of events organized by the Jedi in an attempt to exterminate the Sith devotees, along with their creations left after the Great Sith War, such as silan, giant Sith wyrms and terentateks, creatures native to Korriban which fed off the blood of Force-sensitives. None of the hunts were ever completely successful, and the terentateks always slowly rebuilt their numbers, rising again whenever the Sith did.
