I currently have access to and have cleared out the basement area in Vigil's Keep.
Including locating, and subsequently decimating, Adria.
Sergeant Maverlies keeps saying that "The men are still clearing the rubble in the basement. They'll be finished soon." I've walked all the way back down a few times now, but the only options I have are to look around or return to the surface.
When will they be finished clearing the way? Is there a certain amount of time that has to pass, certain locations I need to visit, or certain quests I need to finish first?
