The Dwemer like robots. What are robots, if not mechanical slaves? Hell, iirc the word "robot" actually comes from an eastern european word for "slave." The Dwemer were always fans of experimenting, and using drugs & mutagens to transform their cousins into fleshy robots sounds like one hell of an experiment.
In Skyrim that works, 'cause Kyne is so important to the Nords, but other than that TES is remarkably free of the sky/heaven, earth/hell archetype. To my knowledge. After all, Oblivion is up, too. The difference is towers - the Dwemer did that, too, but differently than everyone else. Naturally.
The Nords, Cyrods, and Khajiit worship heavenly bodies (moons & planets).
The Altmer and Bosmer worship the planets, the sun, and the stars.
The Dunmer worship the black night void.
The Argonians are weird, and I'm not quite sure how the Ragada view the locations of their gods, but otherwise, the supernatural is generally viewed as being "up" AFAIK.
