Shape-shifters haunt back roads and lonely highways. Immortal beings walk the streets unnoticed and pursue centuries-old agendas. Secret societies manipulate world events and decide the fate of millions. Ancient African cults call on gods and spirits to do their bidding. And those marked with the Taint of the Mad Gods must make a choice—serve entities from beyond reality or fight to preserve the world and their very sanity. The approaching Reckoning will spare no one, human or monster, mortal or undying. Hidden Covenants are forced to set aside ancient feuds or long-held vows of secrecy, and step forward to face terrible new foes. Their choices may help save humankind, or doom it completely. Fear not the monsters, but the beings the monsters fear. Abomination Codex is a supplement for the WitchCraft roleplaying game.
