Now we know that the empire still has some hold of Skyrim as some cities remain loyal. We also know that others do not. In the case that this conflict isnt settled during the main quest this presents an opportunity. What if we could join the legion as well as the faction of nords that rebels against them.
You would be working for various nordic elders and imperial officers around Skyrim. Rising in rank and gaining Imperial and viking gear along the way. Quests would consists out of spying missions, messenger assignments, recruiting and also all out battles between the two factions.
