So I just started the one mages guild quest where you have to go to silorn to help 3 other battle mages get a colossal black soul gem, and everyone was in position waiting for the necromancers to come out, once they got close enough and we attacked them, everyone just started killing eachother, once the necromancers were down, the battle mages were fighting eachother, the last person left alive was Iver. I'm not sure if they all managed to accidently hit each other and become aggressive toward one another, which would be odd considering everyone was attacking each other, and the chances of that happening don't seem too high. Just thought I'd share this story with everyone, I thought it was pretty amusing to sit back and watch everyone kill each other.
