The Revanchist Empire is a Sith based organization headed by Decimate and centered around Korriban, Ziost, and the Corporate Sector. They are radically Sith and do not wish any alliances or peace with any government supporting Jedi. Decimate worked with Kracor, Lucifer, Vexen, and several other Sith to form a hunting party to eliminate the remnants of Darkness which they all viewed as a rival and a threat.
