It's CALL of CTHULHU: The Crimson Letters, session four, wherein the Keeper of Arcane Lore (aka, Lee) guides our intrepid investigators deeper into the mystery of the missing Witch Letters and the gruesome, unnatural demise of Professor Charles Leiter. Will Dorothy, Doc and Micheal ever be able to escape the strange hell Rex hath wrought by chopping off and putting in his pocket a collection of human toes? Probably not. This is 1921 Arkham, Massachusetts... where all actions, thoughts, dreams, and intentions can have consequences... dire ones.
