All the important rules and charts at a glance! The Keeper Screen is an essential play aid for any Keeper running games of Call of Cthulhu. A 3-panel Keeper Screen mounted on thick hardcover stock. One side, intended to face the players, portrays glorious artwork of a team of investigators readying themselves for an excursion into a Mayan Temple (or is it something else?). The rear of the screen, the Keeper's side, collects and summarizes important rules, statistics and charts, to assist the Keeper when running games.Also inside, are two scenarios set in Lovecraft Country during the 1920s: Blackwater Creek and Missed Dues; a 24-page reference booklet of charts and rules; Twelve, ready to play, pre-generated investigators; and color maps of Lovecraft Country, the World of Cthulhu, and Arkham Environs.
