Product Description

“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 Liber 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.

Within these pages are detailed nearly every imaginable facet of the campaign, from starting play to ending things with a bang; explaining, exploring, and expanding the classic work. There is something for everyone, from novice game masters to Grognardian disciples of Cthulhu.
