Victun bloodline

The bloodline of the Sith Lord Darth Victun, a member of the ruling Dark Council of the Sith Empire, was eradicated around the year 4,043 BBY on the orders of the Dark Council. The order was issued after Victun and his rival Darth Qalar destroyed the Imperial Citadel on the planet Dromund Kaas in a Kggath, or ritual Sith duel. Victun and Qalar were both killed by the rest of the Council after their duel, and their family lines were eliminated as further punishment.
