Welcome to the Masks of Nyarlathotep Companion news page

What is the MONC?

The MONC is more than 700 pages of additional supplementary material designed to augment Chaosium’s Masks of Nyarlathotep campaign for sixth edition Call of Cthulhu.

The MONC’s breadth of knowledge and advice was culled from the shared wisdom of the yog-sothoth.com community.

You do not the need the MONC to run Masks of Nyarlathotep as it is not essential, but it could help. The recent seventh edition of the Masks of Nyarlathotep campaign was rewritten making the MONC less relevant, as it was written for an earlier edition.

History of the MONC

In 2015 Sixtystone Press and Sentinel Hill Press in conjunction with Innsmouth House Press successfully completed a Kickstarter project to raise funds for yog-sothoth.com, the Internet’s premier Lovecraftian website and community.

In 2017 more than 700 printed copies of the MONC were delivered to KS backers and late backers.

In 2017, Chaosium offered 250 print copies of a special edition of the MONC to their customers.


The MONC was available to late backers between 2015-17 and from Chaosium in 2017.

At the moment, the MONC is unavailable due to licencing requirements; it is a product designed for sixth edition, and Chaosium only licenses products designed for the current seventh edition of Call of Cthulhu.

Additionally, the Kickstarter was promoted on the basis that the KS campaign was the only way to access the PDF and printed versions of the MONC. We are morally prevented from selling the KS version of the MONC as an obligation to our honoured KS and late backers.

We have been given special dispensation by Chaosium to sell the MONC on the Miskatonic Repository, subject to some required content changes, and format changes. This will be a different version of the MONC in content and format. We are currently working on making these changes but other projects have priority at the moment.

How can I find out when the MONC is being republished?

As stated above, the KS version of the MONC will never be republished; instead a re-edited and reformatted version of the MONC will hopefully be available in the near future.
