I definitely defeated the quest for Blood Brothers, and I even received the quest to find the Hrundle Trogg from Prospector Zeke. I just turned level 55 and I want to enter Wintertusk for my spell quest, but I haven't received anything. I went to Ambrose, nothing. I around Grizzleheim and I went to Olde Town to where that bear is, and no one wants to talk to me! My status in Grizzleheim is stagnate and I don't even know how to get to Wintertusk since I have no quests with directions.
