Cults of Excess

The Cults of Excess, as the many deviant groups associated with the worship of forbidden Elven deities are collectively known, have remained a constant thorn in the side of the High Elves, even after the Sundering. Most commonly known of these proscribed sects are the Cult of Luxury and the Cult of Pleasure. The Cult of Pleasure in particular is renowned for its wanton violence and cruelty, something that has earned it the enmity of all right-minded High Elves.
