Cult of Cythuxos

The Cult of Cuthuxos was a religious cult founded by Avlin’uhzi Udru. They revered Cythuxos as a deity and the ordained sole user of the Force. The cult sought to destroy all Force users, focusing on the Jedi. In 24 BBY, they lured thirty Jedi to their base on Sephyggdur. The battle resulted in a Jedi victory, decimating the cult.

History
Following a divine encounter with the Zolbruti Cythuxos, the Gluss'sa'Nikto Avlin’uhzi Udru traveled around Hutt Space and indoctrinated three-hundred orphans and wanderers into his cult. Operating out of an abandoned Malagarrian industrial bunker on Sephyggdur, the cult spent their time plotting and practicing brutal ways to kill and break the minds of Force users. They awaited the Scourging of the Heretics, the event that would allow them to massacre a great number of Jedi.

Preparing for the Scourging of the Heretics
In the cult's prime, several members left Sephyggdur and established bases across the galaxy in order to use their most powerful asset: word of mouth. Shortly before the start of the Clone Wars, the cult began to spread a rumor that their main temple on Sephyggdur was a site for the manufacturing of weapons to aid the rise of the Sith. Their intentions were for the Jedi to send a large number of Knights to investigate and shut down the operation, where the cultists would be waiting to attack them.

Word reaches the Council
Upon hearing talk of a possible army being raised to aid the return of the Sith, the Jedi Council issues a high-priority mission to an industrial factory on Sephyggdur, sending twenty Knights and ten Padawans to put a swift end to the potential uprising. Among the chosen Jedi are Masters Chi Xu-Wuu and Varah Sar and their Padawans, Khoury Al'Khar and Ma'zaari Mirajj.

Attack on Sephyggdur
Once the Jedi arrive at the bunker, they are immediately set upon by berserking cultists. Avlin’uhzi Udru, protected by four of his most fearsome and dedicated warriors, is found by Xu-Wuu, Varah, Khoury, Ma’zaari, and two other Jedi Knights. The four Knights fight the warriors, and the two Padawans fight Udru. The two other Knights are killed, and Xu-Wuu and Varah become incapacitated and are nearly killed before Khoury and Maz gain the upper hand against Udru and kill him. The four Cythuxist warriors, outraged and distraught, swear vengeance on the Padawans before retreating, making them the only known survivors of the battle. The battle on Sephyggdur causes the deaths of half of the sent Jedi, but also results in a Jedi victory, with the cult being destroyed.

Beliefs
The Cythuxists believed use of the Force in any capacity by mortals is heretical. Only Cythuxos was to wield the power of the Force, and for a mortal to do so was a direct challenge and insult to its divine authority. Avlin’uhzi Udru served as the mouth and hand of Cythuxos, spreading its message and rallying followers to its cause.
