Call of Cthulhu RPG (de/eng)
The Old Ones ruled the earth aeons before the rise of humanity. Traces of their cyclopean cities can still be found on remote islands, buried amid the shifting desert sands, and in the frozen wastes of the polar extremes. Originally they came to this world from the stars. They sleep now, some deep within the earth or beneath the sea.
When the stars are right they shall again walk the earth.
