A man from Yule is refusing to leave the house, having given in to his dislike of the cold.
This errand is available to complete after defeating Cap'n Crossbones and arriving at Yule.
The man in question is in the elder's home on the northeast part of town. Talk to him to find that he's missing his restraint. You should still have some from Hamelin (if not, go grab it) so give it to him to restore him to normal.
