Nane's Stash is a note found inside a chest in a house in Gloomwald. Finding this note initiates The Gloomwald Stash side quest.
I don't know what he's up to but twice in the last week I've seen Nane driving a loaded wagon up the North road past the old mill. Then twice returning with the wagon empty. He must be hiding something up there and I mean to find out where. If he's made it big, I fully intend to be in on his good fortunes.
