The Sith Cult of Darth Cordas, also known as Darth Cordas' Sith and later The Sith Sword Cult occurred several years after the apparent death of Darth Cordas while he was still a leader of the Tri-Sith Order. It happened when Darth Cordas felt betrayed by his co-leaders. Cordas then found Dark Jedi and exiled Sith and with them formed a Dark Side cult that was called Darth Cordas' Reborn Sith
This group eventually died out with many of its members joining the Sith and many of their descendats helped to form or joinde the recreated order of the Fire Force
