Very frustrated with this quest...I spent all day lurking around in caves, bogs, and forrests and have seen nothing. What am I doing wrong? It feel so pointless to just wander for the sake of wandering, with no other quest to fulfill at the time. Is this really the only hint to the puzzle we have is to look for ghosts? Perhaps I should focus on making stockpiles of food or earning trophies until another quest comes along, and let this one go?
