The Definitive Guide to the Cthulhu Mythos
From Azathoth to Zylac—the Encyclopedia Cthulhiana is an essential resource for cosmic horror enthusiasts, gamers, collectors, and researchers.
Fully revised and updated for the 21st century.
What's Inside?
Learn the origins of the alien gods and monsters from the pantheons of H. P. Lovecraft and beyond. Gaze upon the detailed images of the Elder Gods while unlocking the history of the dreaded Necronomicon—if you dare!
Every Monster, Everywhere
The Encyclopedia Cthuliana contains detailed entries on Mythos deities, Mythos monsters, forbidden tomes, and forgotten artifacts—including their appearances across all fiction, gaming, and popular culture.
Rendered To Horrible Life
This epic tome contains evocative illustrations throughout— Nyarlathotep, Hastur, and Cthulhu realised in full color! Use the Encyclopedia Cthuliana to fill your imagination with entities of the Mythos like never before.
The Mythos Explained
More than just an encyclopedia, the book includes an in-depth essay titled “What is the Cthulhu Mythos?” It also covers the timelines for the Necronomicon and the Cthulhu Mythos, and the extensive bibliography of cosmic horror texts from fiction provides perfect further reading for newcomers and scholars alike.
The Encyclopedia Cthuliana is a rules-agnostic book that contains no game material. It can be used to enhance your games of Call of Cthulhu with more detail and terror, or simply as the star of a Cthulhu Mythos library.
