Character from Curse of Strahd by Tracy & Laura Hickman, Chris Perkins / Wizards of the Coast
A night hag disguised as an old woman who sells dream pastries to the desperate people of Barovia — the pastries are made from the bones of children she and her daughters grind at Old Bonegrinder.
Morgantha appears as a stooped old woman with a basket of sweet-smelling pastries, shuffling through the village of Barovia hawking her wares. The pastries are called dream pastries, and they are powerfully addictive — one bite sends the eater into blissful dreams of a life without fear, without Strahd, without the mist. The Barovians pay anything for them. Some have sold their children. This is not a metaphor. Morgantha and her two daughters — Bella Sunbane and Offalia Wormwiggle — are night hags who operate out of Old Bonegrinder, a decrepit windmill on the road between Barovia and Vallaki. They grind children's bones into the flour that makes the pastries. The operation is exactly as monstrous as it sounds, conducted with the casual efficiency of bakers who simply use a different ingredient. Morgantha is shrewd, patient, and utterly without compassion. She sees Barovians as livestock and their children as raw materials. She is one of the most purely evil beings in the valley.
Also known as: Morgantha, the old pastry woman, the dream pastry hag
