Misdeeds & Madness: A Sourcebook of Forbidden Lore for the Mazes & Minotaurs Roleplaying Game is a mature-themed supplement that was supposedly released in 1976. The sourcebook parodies the growing religious sentiment against Dungeons & Dragons by incorporating Greek-themed versions of the hot topics, including assassins, poisons, sexually-based classes (satyrs, maenads, hierokeryxes), rules for drunkeness, witches/necromancers, and gruesome and sexual magic items.
