Imperials vs Stormcloaks

Interestingly enough, this is sort of touched upon in the quest Season Unending, although it only appears under certain conditions so I think most players are unaware, I've yet to play it through myself but may try on my next play through (spoilers on the link below obviously):

I don't think those conditions are all that obscure, I got that on my first playthrough because the Civil War questline was boring and I couldn't be bothered to finish it.
