I was told to find the answers to the Gaulder Amulet mystery by finding Danas Valan in Solusthein.
The arrow ends up in downtown Raven Rock between the Lenth farmhouse front door and the well.
The guy isn't there even after waiting and putting on the amulet. I'm thinking maybe he died in a Dragon attack? Just asking if there is a prompt to make him show or if this character will just remain ignorant.
