Sandy Petersen’s Cthulhu Mythos
The Ultimate Guide to the Cthulhu Mythos in Roleplaying
Sandy Petersen’s Cthulhu Mythos is the most comprehensive guide to including Lovecraftian elements in your Roleplaying game, written by the author of the groundbreaking Call of Cthulhu role-playing game, and developed primarily by James Jacobs (creative director of Paizo) and David N. Ross.
This massive tome contains over 100 monster stat blocks, dozens of which are Cthulhu Mythos monsters that have never been described for Pathfinder or Dungeons and Dragons 5e – including new rules for interacting with 25 different Great Old Ones and Outer Gods (they are much more than a simple encounter!).
This is much more than a mere bestiary, however. Inside you will find new rules for Insanity and Dreams; 40 new spells and 30 Rituals – a new magic ruleset; dozens of mythos items and artifacts; dozens of Mythos cults detailed; and four new player races from Lovecraft’s universe – Dreamlands Cats, Mythos Ghouls, Gnorri, and Zoogs – as well as new character options, professions, feats, and race options for them.
The Pathfinder edition is a massive 512 pages and was released in 2018. Nearly sold out, the reprinting was begun in Fall 2018 with major changes to the art for each stat block. The first edition included photographs of professionally painted miniatures for each stat block. The reprint, by contrast, contains full color illustrations for each! The content is otherwise identical.
5e Fantasy Edition
In October we are launching a Kickstarter for the new edition of the book to be compatible with 5e fantasy. This is not merely a conversion from the Pathfinder edition, but rather a reimagining. It also contains new features, including:
Over 70 new illustrations not seen in the Pathfinder edition!
A new avatar of Nyarlathotep, the Dark Demon, as well as more former-human horrors
Dozens more monsters
Two new backgrounds (cultist and visionary)
More Dreamlands denizens
New character options
The 5e Fantasy edition is already written, edited, illustrated, and laid out. We are in the final proofreading stages. Because of this, it will go to print immediately after the Kickstarter campaign is funded!
Sandy Petersen's Cthulhu Mythos for 5e is now available in German and Italian. To see more details, please click the links below. The book is also planned to be published in French and Spanish in late 2019.
Dark Eye Edition coming 2019!
Our friends at Ulisses reached out to us last year requesting to convert the book for their Dark Eye roleplaying game. They are in the process of developing it now, for both their German and English editions!
