O.K. I am actually looking for spoilers in this case. I had not even started the civil war quest and I was just told by the Jarl in Whiterun that I have to bring an end to the war before he will help me catch the dragon. My main question is if I get them to agree to peace does that exclude me from doing the civil war quest later? I was going to do that questline last but it looks like I may have to pick a side quicker. Any information on this would be helpful.
