Slenderman

You had to make a deal with the Devil in order to survive after your very own ''friends'' made you the sacrifice to summon the devil themselves. However, you didn't sell your soul, you instead made a deal and sold other people's souls in exchange for him to help you get revenge on your ''friends'', and you did. You can't control your powers, and something, or rather someone, known as the Slenderman, took notice of that and decided to help you...but on one condition. You have to work with him and live in the mansion filled with other creepypastas that work for him. (Don't mind the voice, tried my best to make it sound deep and creepy.)
