For when categories fail to box these particular entities for the moment.

21 horsemen 2

??? : Who and what are these things? They’re seldom seen but if Freya’s first hand account is anything to go by, you do not want to try find out. These black robed entities are responsible for the vaccuum of deities suddenly appearing, it seems, and are the last thing Amaterasu should ever happen across.
Now that they have forcibly ceased the heavenly battle in Dublin, they have revealed themselves to be the Four Horsemen though seemingly not that interested in the Apocalypse that they are usually associated with.

31 ahriman 2

???: An ominous, evil entity that seems to be the thing telling Set what to do… with unfortunate success. Can take over the minds of gods mentally weakened by needless animosities.
