Despite being a haunted event and ostensibly having no purpose but to scare whoever pays for a ticket to the park, the houses for Theatre/HalloweenHorrorNights are famous among the haunt community for often having elaborate backstories and defined characters, sometimes even telling a consistent story through the house. Each folder will include links to the pages for each house and scarezone, with the aim for eventually creating a comprehensive database of the layout of the haunted mazes, scarezones, and the tropes inherent in each.
