Legend has it that three dimensions form the world we know: the Human World, the World of Man-Beasts, and the World of Monster Demons. Every 30 centuries, the Overfiend awakens and possesses a human host to usher in an era of destruction by merging the three domains into a twisted new realm of otherworldly excitement. However, this new world is a terrifying place rife with unspeakable violence, uncontrollable desires, and supernatural forces beyond human understanding. Can humankind find a way to prevail? Will the Legend of the Overfiend transcend myth and become our horrible reality?
