AS ROME¿S INFLUENCE SPREADS across the known world, so too spreads the worship of its gods. Roman leaders know that converting the people of conquered regions to the state religion makes them easier to control. But some gods have been worshipped longer than Rome has existed, and their supplicants won¿t easily change allegiances. The Cthulhu Invictus Companion is a collection of three scenarios for Call of Cthulhu, pitting investigators against cults from different regions of the ancient Roman Empire.
