The time is somewhere around 1450 BC. The newborn Roman Empire is starting to rise in the West. The Great civilizations of the Greeks, the Persians, and the Egyptions are still in power. The first vestiges of civilization are just beginning to crop up in Japan, which is still a tribal society. Demons of frightening power are almost as common as humans now. Some are worshiped as gods. Others are seen for what they truly are and feared. Five particularly great demons exist, ruling over the now mighty demon empire than spans the entire globe. They are known as the demon lords and they have no equals, save for them selves.
