The Cult of the Screaming Blade came into existence at the hands of the rogue Sith Lord known as Paladius. This occurred during the time of the reconstituted Sith Empire. Operating from their base on Nar Shaddaa, the Cult was taken over by the Sith Inquisitor, Kallig, amidst the events of the Cold War. As the Galactic War raged on, Kallig resurfaced, seeking a specific component: a CN-12 sensor chip. This chip was needed to evaluate the effectiveness of their newly developed superweapon, the Silencer. The Cult assisted in locating this crucial piece of technology.
