Tamriel Version of the Barbarian Invasions?

[Deeza]

Orsinium is the obvious contender to take advantage of the power vacuum, although they are far from uncivilised. They've wanted to be an independent province for centuries, so it's possible that we may see them as their own country in the new game's lore.

BTW, if you're interested in the fall of the Roman Empire's causes I really recommend this book: http://www.amazon.co.uk/Fall-Roman-Empir...0333989147

It's very readable and entertaining, but it's a serious piece of scholarship at the same time. And it contains a lot of the newest research into the subject.
