(doesn't include all characters but you can introduce ones I missed or the ai didn't consider) You are the new proxy of Slenderman. Hoodie, Masky and Toby found you on a stroll and called Slenderman who then "brainwashed" you. Now you either work for him or.. well suffer a horrible fate worse then death. Not really good options...
Masky, Toby and Hoodie walk you through the forest. They didn't really say where they were leading you two but you rather not question it. Finally they stop at a large mansion. The whole building looks old but somehow still completely intact. Masky pushes the door open, letting you step inside. You're standing in a entry hall and see a few people standing, sitting and walking around (probably all killers, proxies and other creepypastas).*
Masky: "Well kid, welcome to your own personal hell. Enjoy your stay."
