Darth Qalar

Darth Qalar was a Dark Lord of the Sith of Human or Sith pureblood descent and member of the reconstituted Sith Empire's ruling Dark Council around 4043 BBY. Qalar fought a violent Kaggath, an ancient Sith ritual duel, against fellow Dark Councilor Darth Victun which obliterated the Imperial Citadel on the Empire's capital planet of Dromund Kaas. When the two called a draw, the other members of the Dark Council promptly executed both Qalar and Victun, and the personal assets of the two Councilors were used in the reconstruction while their family lines were eliminated.
