I've been told to talk to Bryinolf to get more info on the dragons. No matter what I do, he makes me do "a chance arrangement" to get the info. Researched the quest, and all it seems to say is that it's the first quest for the thieves' guild. Look, I have no interest in joining, I just want to move on with the "dragon" arc. So, is there anyway I can get the info on the dragons from Bryinolf without joining the guild?
