Would Eldritch Abominations, like Yog and others, be considered divine spirits in the Fate Universe or would they be a different category entirely?
Yog like Yog-Sogoth ? well in the Lovecraft world they are viewed as gods , gods of the highest rank , not very versed with either worlds but divine spirits in fate i think are lesser gods of lower rank , i think don't know for sure . Considering how an eldritch abomination looks and what horror and insanity it brings i would say they can be viewed as great superior demons maybe.
they would be "demons." A type of divine spirit that innately have reality marbles which is how they see the world, and how anyone who's in their RMs see the world.
Appearance wise to me she's like a cross between Kirie from Himouto Umaru-chan and Tomoko from WataMote.
