I have done all of the quests for the councilors under skar (the big shell). I just went around to all of them and they keep telling me about the red book of councilors which I have and I have read all of their names. I have completed all of the quests but the plot does not advance. Alternatively, my google searches only turn up the official fan sites which are mazes where they show you 500 advertizements of skyrim. I used to go to one but I cannot find it.
