When I go there I just walk through it like any other part of the map not yet open for exploration. Is there something that needs to happen for it to actually let me in, like a quest or something? All my main story quests except for the sloth demon are completed, but still nothing. Is my save bugged out, or is there some sort of sequence I haven't triggered?
Nearly all locations on the map are unlocked once a quest needs you to go there. In this case, you need to complete the Mountainreach quest (Eternal Day of Sloth), and iirc after that you get/can get the quest for Verdeaux.
