In the Cohors Cthulhu RPG: Gamesmaster's Guide, you will find everything you need to know about the game's factions, the history of the Hidden Wars, a guide to the frontier town of Laurium, and much more. Lead your players into a world of brutal battles, intrigue, and Lovecraftian horror, where the Roman Empire expands its borders and legionaries join forces with barbarian enemies to face nameless terrors together.

Will your players become legends, or will they, like so many others, succumb to the temptations offered by the ancient gods of the Cthulhu Mythos? Their fates are in your hands…

Cohors Cthulhu RPG uses the same 2d20 game system as the successful Achtung! Cthulhu 2d20 RPG.

The manual is in English.

CONTROL THE COURSE OF THE HIDDEN WARS!

Take your place as gamemaster of a dark epic RPG set in an age of world-shaking heroes and villains vying to protect or corrupt humanity. This is a setting rife with brutal battles, sinister plots, and murderous intrigue, blending Lovecraftian cosmic horror with ancient civilizations who must rise above old feuds.

As gamemaster, you will bring this world to life, shining a light into dark corners along the borders of an expanding empire encroaching on proud cultures already beset by nefarious threats.

The supernatural wars are instigated and controlled by secretive cabals. The most powerful of these are led by quasi-immortal beings who have turned to dark magic, poorly understood relics, and unholy pacts to extend their lifespans. This includes the last remnants of fallen Atlantis, whose shadow spreads wide. Some of these groups are largely benevolent, if pragmatic and sometimes cruel, seeking to safeguard humanity against its greatest foes. Others are fully devoted to the Outer Gods and would see the world burn.

Will your players rise to become great legends or, like so many others, fall to the corruptible temptations offered by Mythos Gods? Their fates are in your hands.
