Soon Nyarlathotep’s plans will come to fruition. Then the world will be changed irrevocably — but not quite yet. Pesky human investigators have learned much, but they must survive long enough to make sense of what they know, and take resolute action.

This roleplaying classic is a series of linked adventures forming one long and unforgettable Call of Cthulhu campaign. Horrifying deeds and dangerous sorcery dog those who dare attempt to unravel the fate of the Carlyle Expedition. The non-linear narrative keeps players baffled and on their toes. Action is the byword as the player-characters evade or combat cultists, magic, mad men, and the dread powers of the Outer Gods.

Masks of Nyarlathotep is a Lovecraftian exercise in horror and mystery. 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. Meanwhile the keeper must bring to life different exotic locales, recreate the sensibilities of other cultures, and balance non-player-character foes and friends to allow each investigator to earn his or her own destiny — ultimate triumph, perhaps, or perhaps madness and agonizing death.

Masks of Nyarlathotep is a classic Call of Cthulhu campaign, run thousands of times over the years by thousands of different groups. So to change things up, we are tackling the campaign using Trail of Cthulhu. We’ve also added in many elements from other books. This is Masks as you’ve never seen before!
