From publisher blurb:
They worship forgotten gods. They explore strange sciences that would destroy the minds of the uninitiated. They track aliens. They defend the most dangerous books, protect their communities, or seize wealth and power with subtle, potent powers—powers gained from the Outsiders, and the Mythos that futilely attempts to make the Outsiders, gods from inconceivable dimensions, understandable as mere legendry.
Cults of the Mythos not only presents 23 cults for a Cthulhu Awakens Game Master to use—or for players to introduce their characters to—but includes rules for charting the rise, fall, and power of cults, from their wealth to special stunts they can use on behalf of members. Cults belong to a myriad of places and periods, from China’s Red Mask to Thalassology, a human potential movement once known under another name…when it ruled Innsmouth. Cults of the Mythos includes more detail for many cults mentioned in Cthulhu Awakens, as well as new cults, all ready for your next Mythos scenario.
