***Rise Up Against the Gods Themselves!*** Welcome to an epic struggle of heroic mortals pitting blade, spear, and bow against the claws and tentacles of eldritch horrors from beyond the stars. These Hidden Wars in the shadows of ancient Rome are all that safeguards humanity from oblivion. Enter a world of stalwart Roman legionaries, brave Germanic, Gaulic, and Celtic warriors, shrewd schemer from Greece and Britannia, and valiant archers and mystics from distant lands like Parthia, Aegyptus, and the island of Hibernia. Embody these heroes and forge unlikely bonds with former enemies to confront the Cult of Mormo, minions of Nyarlathotep and Yog-Sothoth, and other nefarious cabals. Mi-Go skitter voraciously through the tunnels of lost mines, while Deep Ones lurk beneath the waves seeking sacrifices. Answer the call of secret organizations like the Fingers of Dawn and Temperari, who possess the knowledge and will to defy the malevolent gods. These groups offer the secrets of mystic arts and access to the legendary weapons of Atlantis. Your enemies wield dark magics and profaned relics, their minds corrupted by the whispers of beings like Sarthothus, a shattered god whose divided mind lurks within the very weapons you require to defeat the cults inviting humanity’s doom. Can you prevail against overwhelming odds, or will you succumb, like so many others, to Mythos forces that thrive on conflict and war? This is your story! **This 224 page guide includes:** * Full core 2d20 rules for playing Cohors Cthulhu, including Fortune & Omens, Reach & Guard, Arms & Armor, Mounts and Vehicles and Secondary Characters. * The Path of Heroes: Building your unique heroic character, choosing from 6 cultures (Roman, Germanic, Aegyptian, Gaulic, Greek, and Foederati), 10 backgrounds, 6 archetypes (Mystic, Sage, Schemer, Scoundrel, Scout, and Soldier), and 12 specializations or use Secret Truths, Hidden Talents & campfire tales to save decisions to be revealed later. * A powerful magical system embedded in the cultures of the era with three types of spellcasting: Runic, Oracular, and Celtic. * A rich setting overview, including Correspondence & Rumors, Life in the Empire and provinces, Religious Pantheons, and timelines.
