Darth Quake

Darth Quake was a male Sith Lord and member of the Sith Empire's ruling Shadow Council who lived during the first few centuries of the Empire's existence. During a violent storm on the Imperial capital Balstros, Darth Quake summoned the other twenty nine Councilors to a meeting and convinced them to join his plot to destroy the Lord Emperor, though he kept an army of loyal Sith outside of the meeting in case any of the Councilors refused. The other twenty nine Sith Lords agreed to join Quake's cause, but when they surrounded the Emperor in his throne room in order to kill him, all Councilors unleashed upon their foe, but the Emperor retaliated and instantly killed them all.
