Dark Schemes Herald the End of the World

Reanimation of the classic Call of Cthulhu campaign.

The new edition of Masks of Nyarlathotep is a complete revision and updating of this epic multi-part campaign set in 1925, in which steadfast investigators must unravel secrets and battle the minions of darkness in an attempt to stop world-shattering events from destroying humanity.

Get the Stunning Slipcase Set!

Masks of Nyarlathotep has been comprehensively revised and updated for use with Call of Cthulhu 7th Edition, but may also be run with the Pulp Cthulhu supplement.

  • Global campaign covering seven countries in five continents!
  • Packed with encounters, side-track adventures, detailed adversaries, geographical information, and more!
  • Presented in full color, with new artwork, maps and floor plans, and ready to use player handouts.
  • Appendices collect spells, tomes, artifacts, and travel advice.
  • Ultimate edition, packed full of advice and tips.

Requires the Call of Cthulhu Keeper’s Rulebook (7th edition) to play, and is optionally usable with Pulp Cthulhu.

The original six-chapter campaign featuring adventures in America, England, Egypt, Kenya, Australia, and China have been developed and updated by Mike Mason, Lynne Hardy, Paul Fricker, and Scott Dorward, and feature enhanced and new encounters, sub-plots, and on-point guidance for the Keeper.

Now written to be playable with either standard Call of Cthulhu or Pulp Cthulhu, the text guides the Keeper and allows for both gritty or action-packed pulp styles of play.

The Introduction chapter features a new foreword by Mask’s creator, Larry DiTillio, and goes on to provide an overview of the campaign, it’s key players and their goals and differing agendas, and the important locations the investigators will travel to while they seek to understand the mystery unfolding before them. Additional material looks at the dark god Nyarlathotep, his cults, and his role in the campaign. Guidance is also provided on running the campaign, including considerations of historical depictions, pulp or standard play styles, and lethality level (just how much danger should the investigators’ face). Rounding things out is plenty of advice on creating investigators for the campaign, replacement characters, and ten ready-to-play investigators for those wishing to dive straight into the adventure.

Complete with a Brand New Chapter...

Set in Peru, this new scenario takes place in 1921 and provides an exciting introductory prologue to the campaign, where the investigators meet Jackson Elias, the industrious and charming author, whose researches lead into the globe-spanning mystery. Embarking on an expedition to find a lost South American pyramid, the investigators come face to face with ancient horrors that foreshadow the task ahead.

... and Even More!

And for an added bonus, a Grand Conclusion chapter helps the Keeper to determine just how successful the players have been in tackling the dark schemes of Nyarlathotep’s cults, as well as discussing ways to extend the campaign in a variety of ways.

Each chapter has been tirelessly crossed-referenced to help those running the campaign to keep track of the many locations, characters, player handouts, and items thrown up by the players’ investigation. With new appendices collecting spells, tomes, and artifacts, running the campaign is easiest it has ever been.

We have added Detailed New Appendices!

Running Masks of Nyarlathotep has never been easier thanks to these extensive appendices:

  • Travel – detailing travel times across the world, means of transport, rest and recuperation for traveling investigators, travel events, and also guidance for investigators wishing to learn new skills and improve existing ones.
  • Spells – collects campaign-important spells together for handy reference, with over 30 spells detailed. Including Call the Black Sphinx, the Seal of Nephren-Ka, and the Ward of Anubis, to name but a few.
  • Tomes – during their investigations the investigators may come across a wide range of Mythos tomes, each bulging with forgotten and dark wisdom. This appendix gathers all of the tomes encountered in the campaign, with over 20 detailed listings, each providing background the tome, the lore within, and relevance to the campaign’s plot, be it the dreaded Necronomicon or the abhorred Black Tome.
  • Artifacts – just as there are numerous tomes to be discovered, there are also plenty of strange artifacts to be found (some useful, some deadly). Here, fifteen artifacts are gathered, from the Mask of Hayama to the Headdress of Eyes, from the Adornments of Nitocris to the very strange Device of Rods, Wheels, and Mirrors.

  • The Masks of Nyarlathotep Campaign in two volumes. 666 pages of Adventure!
  • A three part Keeper Screen designed for the campaign
  • A tuckbox set with every player handout

I had heard of this book when it made a splash in 1987, I did not have time then...
Format: Paperback
I did not have time to read this book when it came out because I was a young father, and I was at the beginning of my professional career. Now, almost 40 years later, I am a grandfather and I within months of the end of my professional career. So I made time to read it, finally. What instigated me to do so now, is all the recent activities concerning UAPs and the unexplained sightings of UAPs in the night skies over military bases in New Jersey and, also, in England. Put simply, I was in the mood to give this book a chance. The "story" starts strong with Whitley Strieber's descriptions of his apparent contact with the "visitors." He is a talented fiction writer and that comes through, but after the first 60 or so pages, the story drags and becomes increasingly repetitive, and hard to read. The penultimate chapter may have read well in 1987, with its buzziness, and the power of three....but in 2025 it doesn't. It just sounds so out-of-date like an Oldsmobile Cutlass with a T-top. (Yes that was a real car...Google it.) Then, there are chapters that are nothing more than transcripts of what Whitley, and his late wife, Anne, had said while in sessions under hypnosis; they are barely understandable, let alone readable. The allusions to quantum mechanics later in the book adon't fit very well, and seem to be an afterthought and are very hard to take. Clearly, Streiber's ideas are not grounded in the science, but in a kind of typical layman's misunderstanding of quantum mechanical "concepts." That is there is an extension of the theory into things it is not meant to explain, and proves that having a little knowledge about something is dangerous. All-in-all, I suffered through the "last," 229 pages (including two appendices), but I can say I have read it from cover to cover. What is my opinion of the abduction story? I hate to be unkind, but it seems more like the memory of a hallucination, or of a very bad and graphic dream, than something that actually happened. It seems to be the product of a fertile and creative mind of a talented author. Yes, there are other people who also claim to have been abducted, and there are some commonalities among their claims, and I know that their numbers should add credibility to their stories, and I know it is unkind to doubt them, but I do and I remain skeptical. So did Whitley Streiber write this book knowing full well that is was actual a work of fiction while claiming it was non-fiction, or did he write it honestly thinking that he was sharing objective truths? On this, it is very hard to know...it is plausible that he really believes these things happened to him, and that he wrote about them sincerely. The author himself seems never to be sure. His lie detector results seem to indicate that he is telling something that he truly believes, but one never knows for sure. To sum up, I am glad the book is no longer a mystery to me. My curiosity was satisfied and that is enough for me, but it took work.

Read this book to begin your study!
Format: Kindle
If you can read only one book on UFO abductions, read this one! This book is amazing and will give you a very good idea about what these UFO abductees are experiencing. This is the book that launched me on an ongoing UFO study which has led to my obtaining and reading tons of books on UFO and abductions. While not an abductee myself and, in fact, I have arguably never even seen a UFO, I know that there is something to this phenomenon that we do not understand. The interest seen in the public square now and the government's greater focus on the UFO phenomena leads one to conclude that what is happening is real and unknown. While I personally believe that the UFO phenomena is a spiritual one involving the unseen spirit world, that is just one of the many theories out there. Read this book and embark on a fascinating journey for yourself.

What evolution looks like when it's applied to the conscious mind
Format: Kindle
It's difficult to say what this book has meant to me over the last 30(?!) years. It is one I return to again and again, and I always get something new from it. The Strieber's commitment to living in the question and keeping it open without jumping to conclusions about where the beings originate and why they are here should be a master class for investigators in the field. There were concepts so foreign to me when I first read this as a teen who was only there for "the alien stuff" that now resonate so deeply. Concepts beyond the question of the visitors; ruminations on spirituality, meditation, marriage that have been a guiding force in my life. I grew up surrounded by awful marriages, reading a man talk so reverently about his wife and their life together actually changed my perception of what was possible in relationships. This book has ruined most other books by experiencers for me, because while others may certainly have interesting stories, they aren't all gifted writers of this caliber. The sincerity, confusion, fear, and ultimately bravery to confront the unknown are palpable. I can't wait to read the new introduction and dive into the mystery all over again.
