Masks of Nyarlathotep is a Lovecraftian exercise in horror and mystery. This Call of Cthulhu roleplaying classic is a series of linked adventures forming one long and unforgettable campaign. Horrifying deeds and dangerous sorcery dog those who dare attempt to unravel the fate of the Carlyle Expedition. Set in 1925, adventures begin in New York, then move overseas to England, Egypt, Kenya Colony, Shanghai, and western Australia. Such extended globetrotting requires wit and planning by the players. Their investigators must have steady finances, good language skills, and a willingness to persevere despite governmental interference and cultist harassment.
