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.[1a]
Due to conflicts with canon, it is inconclusive whether or not the Cult of Luxury represents those elves who worship Atharti, while the Cult of Pleasure represent those who worship Slaanesh, vice-versa, or whether they're one in the same.
