In the world of Nightfall there are two kinds of supernatural beings beyond the mortals of the land. There are the Gods, the beings created as an embodiment or pure being made up of certain exact ideals and peoples. Even the weakest of these beings possess power far beyond mortal comprehension, however they have many rules surrounding how they must use it and often must work through heroes and villains on the mortal planes of existence. They are not a physical or tangible creature on our plane as well, they sometimes take on the aspects of a mortal to walk among us, but only very rarely and at great risk to themselves.

The other kind of supernatural being in Nightfall are the spirits. These are not the ghosts or leftovers of a mortals death, nor the creations of the gods, at least not that we know (there is some speculation that many of them are creations of Gutai to tend his world, but this is not proven) These beings are far more tangible than gods, and are often worshiped as such, but are also far less understood. They do not seem to have an exact purpose, they do not embody exact ideals or ideas as the gods do. They also reside on our plane of reality in their entirety. They are not outsiders or newcomers to this plane. They wander our world for unknown reasons and often disregard all mortals or do not even notice their existence. They rarely are seen and even more rarely spoken too.
