Featuring four unique decks (Curious Characters, Phobia, Unfortunate Events, and Weapons and Artifacts) for use with the Call of Cthulhu roleplaying game, each 48-card deck provides the Keeper and players with handy references and information for use in the game. Each card is unique and provides detailed information of an in-game artifact, character, event, or episode of madness, as well as representational artwork or period imagery.
