Editing Chaos Cults (section)

===Mystery Cults/Secret Societies===
These cults center around the secrets and mysteries (hence the name) held within the highest ranks of the cult that the cult's power and authority stems from. In exchange for their loyalty and service to the aforementioned highest ranks, the cultists are promised the potential to learn and wield these secrets for themselves, which the cult guards carefully from any outsiders who might seek to learn them without pledging themselves to the cult in the process. The Warrior Lodges that formed within many of the Legiones Astartes near the end of the Great Crusade are a classic example of how a mystery cult operates, and their effects [[Horus Heresy|speak for themselves]].

Technically, these "mysteries" don't necessarily have to be Chaotic in origin or even particularly religious in nature, and one could easily argue that the [[Adeptus Mechanicus]] is the most successful of all mystery cults. They certainly have the "mystery" part down, given their persistent refusal to tell anyone outside the cult how the average machine works.
