It really has got to have something to do with Akavir. Surely their is no other feesable explanation. http://www.uesp.net/wiki/Lore:Akavir Read that for more details. And yes, Don't you like the emblem for Akavir, and wonder why it looks exactly the same as the logo for Skyrim? Anyone?
It also looks exactly like the Imperial symbol and the avatar of Akatosh. The symbol appeared on the front cover of Morrowind and was plastered all over Oblivion. Did either of those games involve Akavir. No they didn't. So can people PLEASE stop using this line of reasoning. Also, the voice over negates Akavir with these lines:
"But no-one wanted to believe"
"Believe they even existed.And when the truth finally dawns: It dawns in fire."
Guess what. EVERYONE believes in Akavir. Their are no Akaviri deniers. The dragons are allegory for something, but most definitely NOT Akavir.
