(Oh boy, parallel threads.)
Firstly, I'm not quite sure what to make of the architectural style in the setting. I do see some elements that would strongly imply they're built by the Dwemer, such as the (copper?) roof shingles. It's possible that their settlements in Morrowind were more akin to facilities than actual living quarters, and we'll see some actual steampunk areas in the deepest reaches of these new ruins. Of course at the same time, the Dwemer ruins in Morrowind had desks and beds (something the Ayleid counterparts in Oblivion sorely lacked) so the metal structures still have merit as settlements.
What I'm curious about is just how out of place the Centurions would probably look in this setting. :shrug:
