So on my main toon. 50 hours in lvl32, I decided to finally finish main quest. I'm at the part where white run Jarl wants peace treaty. Now I havnt completed the civil war quest line but I did start it. The whiterun Jarl is not balgruff (sp?) But white-mane (sp?). So my question is this...
Will finishing this quest or civil war line affect the other. I have completed the legion on another toon and killed ulfric. This guy is on cloaks side so I assume will kill legion general.
Likewise if I make peace, assuming I can I havnt done the quest yet, will the peace treaty affect the civil war
I don't care about spoilers just wanna make sure I won't screw up the other quest line either way.

I didn't even think you could do the peace treaty if you already started the civil war quest. I wish I could tell you more. I thought it locked that option out.

Yes then you don't have to make a treaty of peace and you can learn the odaving shout from parthurnax .
