Well, I don't want to align with the Empire because they're an empire. I don't really like the Stormcloaks either, and the Dominion isn't really good for anyone. If it weren't for the poor blind people of Skyrim (bless their 12 second memories), I might have to side with Alduin.
There's a DLC idea. Become the champion Miraak could never be and show the Dominion how to stage an invasion!
