The Cult of the Screaming Blade was formed by the renegade Sith Lord Paladius during the reconstituted Sith Empire. Based on Nar Shaddaa, it was usurped by the Sith Inquisitor, Kallig, during the Cold War. During the Galactic War, Kallig returned in search of a CN-12 sensor chip to test their new weapon, the Silencer. The Cult helped to track it down.
