“Men advised one another to see Nyarlathotep, and shuddered. And where Nyarlathotep went, rest vanished, for the small hours were rent with the screams of nightmare.” H.P. Lovecraft, 1920 “What kind of weapons do Bloody Tongue cultists use?” “What does the Liver Ivonis contain?” “What hospitals are there in Mombasa?” “How do you organize a raid on Gray Dragon Island?” “What do I do if everybody dies???” Ever since its release in 1984, Masks of Nyarlathotep has been considered one of the finest supplements for Call of Cthulhu, a roleplaying classic. Countless players have dared to thwart the machinations of Nyarlathotep and plumb the mysteries of the Carlyle expedition.
