The Essential GM's Reference
This lavish Game Master's Kit helps keep a warband's plots to conquer the Screaming Vortex on Track. Behind the sturdy screen, the GM can hide Dice Rolls and keep players from reading his notes. Printed on the GM's side are numerous handy quick reference charts that make running the game much easier. Added to this is a 32 page full colour booklet with a complete adventure, a selection of useful NPCs, expanded rules for running Black Crusade adventures, and advice for how to run a black crusade.
