Variously compiled from Judeo-Christian texts, literature and mythology, some of the creatures within may be eerily familiar to aficionados of Dungeons and Dragons or students of folklore. Others are more disturbing for their unfamiliarity, providing new fodder for our nightmares. This encyclopedic ABC of demonology features such fell denizens as Beelzebub, Cerebrus, JackO Lantern, Leviathan and Satan alongside lesser-known demons such as Forcas, Gamygyn and Halphas and compiles a record of their wicked deeds and atrocities.
