Cursor looks like it's right in the middle of a mountain I can't get to.
The ONLY complaint I have with this game is the pathing to objectives is terrible. Dead Island was really good about telling you which way you had to go to get to a quest objective. This one just throws a marker on top of a mountain and says "good luck".
I do. I'm assuming you're starting from Morthal, so just follow the path around the mountain. I did the others first so if you're really having too much trouble end with that one and the spell should work. --- Gnarlacious. I'm So Meta, Even This Acronym
