Is there any information (in-game, or externally) about the significant events that transpired in the realm of Tamriel between Oblivion and Skyrim?
At the end of Oblivion, the empire's bloodline died with Martin... but now in Skyrim there's an emperor again?
What's the history with the Aldmeri Dominion?
I did find one in-game book about the Game's 3rd era, but it ended with The Knights of the Nine reforming (Oblivion DLC), and didn't make it up through the intervening span between the games.
