Alkonium said that a new Empire would rise and replace the Mede Empire. I agreed with him and used examples to back up my points. At no point did either of us say that the new Empire would occupy all of Tamriel. I just agreed that after the fall of the current empire, another would eventually take its place as a major power.
I just don't see it. The Empire isn't loved in the Providences in any way that someone from Hammerfell of Skyrim is going to pine for the days of Tiber Septim. In Morrowind or Alinor, the Empire is outright hated. I think for the empire to be revived, it would have to be wanted, and it's obvious that even in Skyrim, no one really wants the Empire. If America fell tommarow, it would be revived as we generally like the idea of being American, and are loyal to the federal government. That wasn't the case in the British Empire or the Soviet Union, in which more people were loyal to their local governments and saw themselves as members of states, not as Brits or Soviets. In the USSR, you would consider yourself Russian or Ukranian or Azerbani, not Soviet. In Britainia, you'd consider yourself Indian, or Bangladeshi, or Irish or something like that, NOT British. It wasn't a national identity, so most outside of the capital region weren't loyal enough to the idea of the empire to want to bring it back. Rome was a cultural identity, as is America today -- that's why people wanted it back. So considering that most people in the providences have no loyalty to even the idea of the empire, I don't see enough push for these newly independent republics to subsume their identity into being a mere state in a larger empire. It would be as realistic as suggesting that India is going to petition to be a state of Great Britain. It isn't likely.
