Potluck just means that I'll be deciding all the details (aliens, magic, all dat jazz.) Feel free to post more detailed suggestions as well Thank'ee much!
I'll suggest a compromise: Stay with TES, because you're here, but write a story set in the time the Dwemer were around, i.e. Elder Scrolls "Steampunk".
The raw power comes from Magic instead of Steam, but it's the same principle. Elaborate mechanisms rule, and there's a "historical" setting, relative to the writer's world. Narrate your story from the present day in Tamriel.
