What area are the mercenaries in the Kva Riverlands?I have not found them even though that section of the game has been thoroughly explored in the past.

I can't get into the wizard's tower. Quests that I have: Hunting the Wizard; History Scrolls, Titan's War Club, The Stolen Totem, and Hunt Down Orian. I was told that the way into the tower of Moritz'Kri would be open for me, but it is not. What else do I need to do to get in the tower? Also Hunt Down Orian - second quest - where can I find him to kill him? Titan's War Club: how can I find this? There are no additional areas opened for me. Berak says "in the hills to the south." What area does he mean? I have searched all over Goldcrag. Hopefully there is still someone on this site that can answer me
