It goes without saying there are spoilers.
While I have been a lifelong fan of Lovecraft's I had never read "Mountains" and just finished it. Towards the end the characters witness "a shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and unforming as pustules of greenish light" and I thought that sounds an awful lot like Hermaeus Mora.
Now we know why HM got a facelift for Dragonborn. Or at least now -I- know, I'm sure others already knew this.
So the Daedric Lord of Fate is, in fact, a Shoggoth. Trippy.
