This story is an easy integration for just about any haunted attraction. The multitude of horrors in your haunt are wrapped into the story as simply more creations of the surgeon, regardless of if they are medical themed or not… the surgeon is a creative artist.
Many aspects of this story are easily altered to fit your needs if required. Maybe Sophia is not the surgeons daughter, maybe she is another victim that aids him in hopes that she will be released? Maybe The Masterpiece wasn’t the gardener because the surgeon isn’t even operating out of his mansion, he is operating out of the basement of an abandoned prison and abducting trespassers.
Characters can be renamed, motives altered, a completely different voiceover artist can be used. The possibilities are vast. All these aspects of the story can be adjusted through re recording of voiceover lines and text/copy based changes on your website and ads to better fit with your haunt.
