Cthulhu Invictus

Roman children tremble in their beds as their mothers tell them stories of Medusa, the Hundred-Handed Ones, and the War of the Titans. They pray that the Fates have woven a long skein for them, free from encounters with the Minotaur and Cerberus. Little do they know that things more horrible than the creatures of myth and legend inhabit the world. A dark god stalks the streets of Rome stealing the souls of the rich and the poor, the young and the old, to populate his empire on the other side of the wall of sleep.

This is the world of Cthulhu Invictus, horror roleplaying in the first century CE, the time of the Roman Empire.
