From the cover: "A sourcebook of Forbidden Lore for the Mazes & Minotaurs roleplaying game." From the title page: "Read this Word of Warning!" "The character classes and mythic items described in this book are not suitable for all campaigns. At best, they are anti-heroic, at worst outright villains and should thus be only used as NPCs. Most self-respecting heroic characters would never associate with them, and neither will NPCs. It will require some care to let them be PCs, and probably some mature players." Contents include: Assassins & Poisons Dionysian Classes Witches & Witchcraft Mythic Items of Infamy
