Realms of Cthulhu


Mythos Horror, Savage Worlds Style
Whether you seek action and adventure battling cultists in sun-drenched jungle temples, a shadowy mileu of dark words and impossible deeds, or a twisted mixture dredged up from the darkest recesses of imagination and nightmare, you will find the rules you need and the inspiration you desire within these pages.

One Overwhelming Truth
Behind every legend, every catastrophe, and every great act of evil throughout and before recorded history, is the secret knowlege that shatters men's minds like fragile glass- the dark influence of alien gods and powers beyond mortal comprehension, things man was not meant to know and things that your investigator must now face.

Body and Soul
In your battle against the dark forces, you not only risk life and limb, but your very sanity, and the innocence of your soul. Will you sacrifice yourself for the greater good, or run for the safety and sanctity of an asylum? Or will you use the knowledge you gain to turn back the tide of evil for another day?

Beyond Time and Space
Mythos Tales can be set in any period and any place. Included are guidelines to get you started with the most popular time eras: the gaslight era of the 1890s, the classic era of the 1920s, and the modern world of today. Explore the setting as best you see fit.

Campaign Styles and the Keeper
Four distinct styles impact how physical damage and mental anguish are handled. This allows you to effortlessly shape and direct the focus of your campaign, from the pulpiness of Heroic Horror to the grim desolation of the Dark Spiral. Insight and advice are offered to the Keeper concerning magic, modifying monsters, and creating adventures, as well as a detailed roster of supporting cast members, and comprehensive bestiary.

Infinite Opportunities for Adventure
Use Mysteries of Dark Manor or any of the other included Mythos Tales to begin your journey down the road to madness immediately, or use the Mythos Tale and Creature Generators to create whole new adventures of your own.

This product is layered, so you get the rich goodness of the horribleness in full color as well as a more printer-friendly iteration.

The publisher seems to have gone dormant so I wouldn’t expect and update or POD version.

Don't buy this by itself. Get the Acthung Cthulhu Three Kings & Realms of Cthulhu bundle. You get this book and an adventure for Acthung Cthulhu for like $15.

For a PFD that is only 160 pages, the price seems way to high.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
