I think Bethesda just needs to bring the Dwemer back...they have been gone long enough....Just bring the Dwemer back in a DLC and the Dragonborn gets to help the Dwemer reclaim their underground cities from the Falmer.

This why in the next Elder SCrolls game, The Dwemer can be a playable race in the game....so they can really add something new.

Have you played morrowind's main storyline? You pretty much nailed exactly what the dwemer are working on in red mountain, their main headquarters.
