Nephilim is a contemporary role-playing game of the occult. Players adopt the role of mystic beings composed of magical elemental fields (Air, Water, Fire, Earth, and Moon). Mysteriously, the Nephilim are now awakening en masse after a long slumber, incarnating in humans, and continuing to acquire occult knowledge. Their ultimate goal is to attain a superior consciousness called Agartha. They face numerous dangers, the principle threat being secret societies, the most determined being the Templars.
