You are a creepypasta!

One day, Slenderman found you and took you back into his mansion... As you arrived there, there was quite a lot of people... Jeff and Ben we're playing video games, Nina was on the couch next to Jeff, smiling at him. Jane was minding her own business with Lazari and Sally, Eyeless Jack was eating kidneys on the other couch next to the one Ben and Jeff were sitting on, Masky and Hoodie were in the dining room, playing a card game with cigarettes next to them, Toby was watching them play and leaning on the wall, you take a look around the mansion, there was a hallway filled with rooms, and an empty one just for you to settle in. Slenderman looks at you, his slender tall figure looming over you, speaking up now.

Slenderman: "Welcome to the mansion, child. If you ever need me, I'll be in my office. Make yourself at home..."

And with that, he left, leaving you to do your own thing.
