In Skyrim, It seems like it makes the most sense for the Dragonborn to be a Nord, since the game takes place in the home of the Nords, and the whole thing sort of revolves around Nordic beliefs and prophecies. Plus the Dragonborn was portrayed as a Nord in all the pre-release stuff.
But the Septims were all Dragonborn, their dragon blood was what gave the Septim line their power to be emperors. Anyone who has played Oblivion a lot should know this. And Tiber Septim was the first of these Dragonborn emperors, so I'd always assumed he was an Imperial, just like the rest of the Septims. That would make sense right?
But in Skyrim it seems like the Nords believe Tiber Septim was a Nord... which would make sense in relation to my first part about the Dragonborn being a Nord. But if Tiber Septim was a Nord, how did he produce a line of Imperials? So are the Nords wrong, and was Tiber Septim an Imperial, meaning it would make sense for the Dragonborn to be an Imperial?
I guess I'm just pretty confused about the whole thing... Does anyone else have thoughts on the matter?
