Mad Mary

Mad Mary is an inhabitant of the town of Barovia.
The party first met Mary when they were on their way out of Barovia, to escort Ireena Kolyana to the town of Vallaki. Mary's wails could be heard all throughout the town, and the reason was soon discovered to be the disappearance of her young child, Gertruda. Mary gave the heroes a keepsake of Gertruda's, a doll from the Vallaki toymaker, Gadof Blinsky.
The heroes did some investigating, and suspect that Gertruda left the house willingly, whether through mind control or free will.
