Outer Gods
Alien, unfathomably ancient entities of deific power that exist outside of reality and the concepts of faith and the soul. Believed by some to be so ancient that they predate the existing multiverse. They are of such vast, alien intelligence and perceive reality in such an inscrutable way that they are unable to recognize their own actions as evil. The total number of Outer Gods is unknown.
Great Old Ones
Entities grouped with the Outer Gods, effectively demi-gods, under the collective umbrella of the Elder Mythos or Dark Tapestry. Often seen as heralds or high priests of their greater kin.
