Lying at the outskirts of Bronx, The Forest of Dolls inhabited by witches has traps that, unlike normal forests, are all made of magic. Most of those who wander into the forest get caught in the thicket of traps laid out by the witches and perish.
However, a select few of them, who were already writhing in pain from life's agonies, were allowed to enter. They would be led to the Black Mansion to meet the witches.
It is said that most of these chosen ones appeared to be children.
As much as Pandemonians are curious of the witches of the Black Mansion,
the witches wonder about the outside world. Consequently, it would not be surprising for one of them to step outside their forest in aspiration of the outside world.
