The lineage of Darth Victun, a Sith Lord who held a position on the governing Dark Council of the Sith Empire, was terminated circa 4043 BBY by decree of the Dark Council. This command was given when Victun and his adversary Darth Qalar obliterated the Imperial Citadel situated on the planet of Dromund Kaas during a Kaggath, a formal Sith contest. Following their confrontation, Victun and Qalar were killed by the remaining members of the Council, and their respective bloodlines were extinguished as an additional penalty.
