The five posts before that quote specifically show MK is referring to Solin, Allerleirauh, and most importantly, Xal's theory on how the Divine Skin was created as a Crux of Transcendence. It's all there for you to read. Or not. *shrug
Perhaps you should spell it out for me... as I don't see anything in that thread that supports the theory.
EDIT: I should clarify; I don't mean the Crux of Transcendence theory. That is well supported. And that makes sense; the Dwemer used the Heart and the Tools as a Crux of Transcendence with the Divine Skin as their shell. They committed mythic, racial suicide - absorbocide. That's what I'm saying. They anti-created themselves into a god using the Heart, the Tools, and Numididium, and then - like Lorkhan and the other gods of the Mundus before them - shattered into smaller soul-bits. Animunculi.
There's nothing there that indicates that they became the 'golden skin' of the Divine Skin.
