Just as there is no one religion in the Imperium, there are many Chaos Cults. In addition to the Is’Malalist Cult detailed on this site, there are other cults dedicated to Khorne, Slaanesh, Nurgle, and Tzeench as well.
Only a few are detailed here, there are literally thousands upon thousands of Chaos cults. Feel free to use the ones detailed in this section as inspiration for your own. If you are inclined, send them to me and I will post the best ones on this site.
