Old Bone Grinder is a windmill just outside of the town of Vallaki. At one time, it was used as a wheat mill by the townsfolk, but long ago fell into disrepair. It was taken over, a few years ago, by the hag Morgantha, and her daughters Bella Sunbane and Offalia Wormwiggle. Upon taking it over, they started making dream pastries. Bella and Offalia would stay home and make more pastries while Morgantha would travel to Vallaki and Barovia to sell them. The windmill was cleared out by the party when they were sent to investigate a pair of missing children.
