O — Old Bonegrinder

Morgantha's windmill. What appeared to be an old mill was the hag's true lair — the source of the dream pastries she sold throughout Barovia. The pastries were made from the ground bones and flesh of children.

The party discovered the truth and burned the windmill down. Morgantha was defeated here. A child died during the encounter — Myra holds Logi responsible for this, believing he ignored warnings that could have prevented it.

Pipwick joined the party in the aftermath, encountered near the windmill after a separate run-in with Strahd in the surrounding forest.

Morgantha survived in some form — her memory brokerage beneath the Ruins of Berez continued operating after the windmill fell.
