Just pointing out some things in the armor design of the creature. For me, the claws and multiple eyes being present in the helmet are too much not to think of Herma-Mora, especially when we put the creature into the context of Skyrim, where we know he is a prominent deity in the Skyrim pantheon, albeit an antagonistic one.
And, I don't know if anyone noticed, but the creature's left pauldron is indeed reminiscent of Madness armor from Shivering isles, since it is very much a face.
Also, the helmet very much resembles http://members.shaw.ca/rado907/armor/light/mor-glassarmor.jpg from Morrowind, both in shape and coloring (If that was where you were getting deja vu from, Lady N!).
EDIT: White hair present in the restored picture (thanks GothObservationist!) is further evidence of the creature being the same as the armor-less one.
