Introduces several new cards specially made for Ritual Monsters.
Story behind the title; I made up a sort of "campaign world" and story in which the players take part in a storyline (similar to the anime). Eight of the "bad guys" are the Duelists of Demise, all of whom are Duel Spirits. The first is Armageddon Knight, who is notable for his strategy of not using any Trap cards at all.
