Navigating the Crawling Chaos


“And where Nyarlathotep went, rest vanished, for the small hours were rent with screams of nightmare.” 

At Prospero House Publishing, you will find a continuously growing collection of articles and resources for Keepers and Players alike to enhance the already unparalleled experience of the legendary Call of Cthulhu Campaign, Masks of Nyarlathotep.

Dedicated Keepers, we shall endeavor to amuse as you work tirelessly to offer up your foolishly bold players the finest experience possible.  We welcome you to peruse our content—you will find our most recent posts here.

Courageous Players, we will seek to inspire you to push forward in brave efforts to unmask the Dark God.  

 For other MoN and CoC fans, we bring you regular updates to our narrative MoN campaign journal.

Together, you can unravel remarkable and unexpected tales of Horror and Madness of incomparable magnitude. We do hope to hear about them should any of you survive. 

For Spoiler Prevention, active and future Players should steer clear of any Keeper-related content during your campaign.
