The Legerdemain Betrayers is a roleplaying game with unique playing card-based mechanics for a group of two-to-four players and a Narrator. Set in a dark, gritty Los Angeles where magic is not only real but extremely dangerous, players assume the roles of four enterprising magicians who have been using their supernatural talents to enhance their acts. The four quickly find themselves in trouble, though, when they discover that there is a whole society of magic-users who are sworn to protect the practice's secrecy.
