Oblivion and Skyrim? 200 years have passed since the end of the Septim dynasty, and the beginning of the Dragonborn prophecy has begun. But what happened in between? The 3rd era only lasted 433 years, and so many things have happened in that time. So could their possibly have been something in between the Dragonborn and the HoK that wasn't recorded in Alduin's Wall? Interesting...

We do know what happens in between.

Thats what happened

I should really do my research before I make a thread...

Never any shame in asking questions. As much as some parts of the internet may think there is.
