Ending Skyrim civil war.

[charlesmcl71]

I found this awesome mod called Dual, I was wondering if there is a way to challenge Ulfric and Galmar and when you win the war ends, you are instructed to see General tulius (or if you are a stormcoak sympathizer lol) which inserts the winner. When you return to Castle dour with Ulfrics head(assuming you use lawbringer etc)  and the dialogue about brun-wulf taking over Windhelm etc. will commence. You are rewarded for your bravery and life goes on.
