|Chronological and political information|
Terrak Morrhage was a Human male Sith Lord of the resurgent Sith Empire dead centuries before the Cold War. He was buried on Malachor III and his spirit remained dormant until was awakened by a Jedi expedition composed of Parkanas Tark, Yuon Par, Duras Fain, Sidonie Garen, Eriz Vossan and Cin Tykan. Morrhage's spirit played with the emotions of the young Jedi and drove them insane. While the rest of the team managed to escape to planet, Tark was left behind to be tortured by Morrhage and, eventually, Morrhage's dark spirit corrupted and possessed him. Years later Morrhage and Tark inflicted their revenge upon those that had left him behind and on the entire Jedi Order. Eventually, they were stopped by the actions of a lone Jedi Consular. Defeated, Morrhage warned the Consular that should Tark die, all the Jedi Masters afflicted by the plague, shielded or not, will die with him and attempted to goad the Consular into striking him down. The Consular instead chose another option and used the shielding ritual to exorcise Morrhage from his host. Screaming with rage, Morrhage swore he would gather his strength and revenge himself upon the Consular before disappearing.
