Headmaster of the Sith Academy
Perhaps the most influential Sith Lord not on the Dark Council. His methods are heavy handed, brutal and effective. His power over the future of the Sith, as Headmaster of the Sith Academy, is without question and that has made him several enemies that have differences of philosophy or are jealous of his power.
His word is law on Korriban and his apprentice is the enforcer of that law. His apprentice, Daemus Karn, is the brightest and most powerful student the academy has seen in decades.
