The World’s Best Game Of Intrigue, Mystery & Horror!

The Old Ones ruled the earth aeons before the rise of humanity. Traces of their cyclopean cities can still be found on remote islands, buried amid the shifting desert sands, and in the frozen wastes of the polar extremes. Originally they came to this world from the stars. They sleep now, some deep within the earth or beneath the sea.

When the stars are right they shall again walk the earth.

Chaosium Unveiled: Inside Inside Call of Cthulhu Keeper Rulebook

Watch the unveiling video to see the book for yourself. Remember that you get the PDF when getting the physical copy.

Call of Cthulhu is the world’s best game of secrets, mysteries, and horror. 

Playing the role of steadfast investigators, you travel to strange and dangerous places, uncover foul plots, and stand against the terrors of the Cthulhu Mythos. You encounter sanity-blasting entities, monsters, and insane cultists. Within strange and forgotten tomes of lore you discover revelations that humanity was not meant to know.

You and your companions may very well decide the fate of the world.

The Keeper Rulebook, contains the core rules, background, guidance, spells, and monsters of the game. It is everything you need for Call of Cthulhu at your fingertips, and will enhance all of your games. The Keeper Rulebook is intended for use by the Keeper of Arcane Lore—the Game Master who will present the scenario to the other players.

The other players—the Investigators—will benefit hugely from a copy of the Investigator Handbook, which contains expanded rules for character creation, skills, occupations, equipment, and a primer on 1920’s New England—the signature setting of Call of Cthulhu.

Monsters, Beasts and Alien Gods!

The Dark Young

A bestiary of mythos entities to pepper your Call of Cthulhu scenarios and campaigns. Each entry contains full rules for using that monster in the game. Whether it’s a lowly Mi-Go, a flesh-changing Deep One, or the great Cthulhu himself, you’ll find background details, stats, special rules and spells to effectively dispatch these wicked beasts upon your hapless investigators.

Tomes of Eldritch Lore

The Tome

Whether at your local library, or among the forbidden bookshelves of a twisted cultist, the Keeper Rulebook provides a wellspring of books for your investigators to find. Rules for reading, researching, and discovering spells come alongside detailed entries for over 20 tomes. Every tome listed in the Keeper Rulebook can serve as the basis of its own story, and to inspire your very own cults to face off against your investigators.

Tome - Cthulhu in the Necronomicon

Sanity

The Scream of Sanity

Full rules for the Sanity system that sets Call of Cthulhu apart from other horror games. The Sanity system measures each investigator’s capacity to comprehend the incomprehensible. It mechanizes the way the human brain can break upon discovering mind-bending truths we were never meant to discover. With each loss of sanity, the investigators will change, and their character will shift and grow. Sanity is the backbone of narrative character development in Call of Cthulhu.

Sanity Loss Example

Scenarios

Two complete scenarios, handouts and pregenerated characters allow you to jump right into the action, or kick off a new campaign.

Amidst the Ancient Trees

Amidst The Ancient Trees - The investigators join a search party for a kidnapped girl, and must venture into the woods of Southwest Vermont in pursuit. What they discover is far worse than they could imagine.

The Horror in Ink

Crimson Letters - The death of a professor at Miskatonic University in Arkham, Massachusetts sets off a chain of events that echo through the entire city. The investigators must solve the unexplained death of the academic before things get out of hand.

    Nailed it

    Posted by Brian Sandall on 10th Nov 2022

    Absolutely gorgeous book, great binding quality, and filled with everything a keeper needs and then some. I really like the rules summaries in the appendices, that's a nice touch and very useful to print out a copy or two for your players.

    This book is lit

    Posted by Nate on 26th Sep 2022

    This book is amazing, and well worth the price of a physical copy. It has an awesome new book smell, and even has a built-in bookmark. Very high production value. The content of course is fantastic as well, as long as you enjoy skill-based games with high levels of player danger and a reduced focus on combat. The layout can be a tad confusing at first, but that's mostly due to the growing pains of learning a new system. My only complaint is that the shipping times are a little long. It took twelve days for my order to arrive following the date of order. That, however, is par for the course for a niche product such as this, but it was nonetheless annoying. That being said, the quality of the product itself more than made up for the wait-time. Overall, if you can put up with a bit of a wait, buying from Chaosium directly is well worth it, especially considering the PDF included in the package (which is immensely helpful for long distance groups). Definitely a purchase I am happy with.

    Indispensible

    Posted by Mike Geib on 26th May 2022

    I would get this even if I was only intending to play Investorgators. Well-built, sturdy, and chock-full of excellent rules and details on the depth of the system and what it's capable of in terms of collaborative storytelling.

    7th Edition Cthulhu Keepers Book

    Posted by Kim White on 27th Mar 2022

    A gem of a product! A beautifully presented and illustrated hard cover book that just SHOUTS “quality” and is a pleasure to hold in your hands. Absolutely worth getting even if you have an earlier Edition.

    Creating a life long fan

    Posted by Thomas Connole on 25th Oct 2021

    Having my start in the tabletop rpg genre with DND, Call of Cthulhu was such a surprising and life changing game to find. The ruleset and lore has everything I ever hoped to have in a tabletop game and more. It is actually quite amazing how much better the quality of this book and others from Chaosium are than the rest of the tabletop rpg market. To name everything that makes these books world class amongst the rest (in my opinion) is the art, design, game structure, rules, character creation, volume and quality of supplements, organization of the book(s), and best of all the feel of the game. This isn't the only tabletop rpg I play, but it will always be my favorite.

    Keeper Rulebook

    Posted by Franklin Diggs on 16th Sep 2021

    This is a really well produced book. I'm not going into content, because you can probably find out about the game easily elsewhere. I want to talk about the book binding and printing. Production is at least equivalent to competitors. I believe it to be Smithe sewn and case bound, but I honestly cant see very well past the headband to see the binding, I'm not at this stuff. Paper is glossy, like other RPG books, thicker than magazine paper, but not as thick as photo paper. Color and alignment consistent throughout. There is a bookmark sewn in. The end pages on this book are amazing and I just wish they would use these end papers all the time. Like. these end papers just tell me the company put the 110% into the production of this book.

    Excellent Product

    Posted by George Graham on 5th Aug 2021

    Excellent Production quality with great artwork, these books have been a joy to read. As a returning gamer to Call of Cthulhu i find the rules clear and concise, i particularly like the chase rules. Looking forward to exploring the mythos again with my group. All in all an excellent product.

    Great book and Amazing customer service!

    Posted by Michael N on 18th Nov 2020

    I am loving this new system and the help customer service gave was very much appreciated! :D I also REALLY like how it comes with a PDF! I can cut back on my screen time while I read the lovely physical copy but during prep or game play I can easily search and reference the PDF! What a game changer! :D

    It's Call of Cthulhu

    Posted by Nick Ingham on 27th Jul 2020

    I probably wouldn't be writing this review if I wasn't going to give *this* book five stars. And you probably wouldn't be reading it if you weren't expecting me to. Well, predictably, I am. In terms of production values, this book somehow manages to be even more beautiful than the green leatherete 25th Anniversary edition. When it comes to the system, the Seventh Edition has changed more than previous ones, though not so much as to make previous products hard to use with it (the thing I find unintuitive so far is that Characteristics are now percentile). Skills have been reworked somewhat: some redundant ones consolidated, a new mechanic for bonuses and penalties, the fumble mechanic adapted to an option to gamble with a second attempt at a failed roll. Mythos tomes have been reworked so there is a benefit (and risk of course) for repeated full reading. There is a chase system to go with the combat system (it works fine, and provides an easy foundation should you want to build a custom subsystem for dealing with some kind of major conflict that's become important in your game). The two scenarios are new to this edition. One is linear, using the classic onion layer model, while the other is more of a sandbox (indeed in the latter, the Keeper is given a number of options as to the identity of the main culprit). A predictable verdict or not, the book deserves its five stars.
