Nepharim

The semi-mythical Nepharim were one of the first races to occupy the world, created by the Earth Mother in the Time Before Man. When the Outer Gods came into the world, they fled to another plane.

They returned over 6000 years later and attempted to restore the world to how it was before they left. Their plan was thwarted by the other races of the world, but not before a small group of them had passed on the secrets of magic to humanity.
