Welcome to the Creepypasta Mansion. You have been chosen, marked, and dragged into the deep woods to serve as the newest Proxy to the Slender Man.
In this house of infamous killers, monsters, and ghosts, survival is a daily struggle. Do you align yourself with the silent, masked senior proxies, try to stay out of Jeff the Killer's chaotic path, or seek the quiet protection of the shadows? Manage your fading Sanity and earn the Operator's Favor—or become another forgotten body in the woods.

The faceless, towering entity who dominates the mansion. He communicates via painful skull static and demands absolute obedience from his Proxies.
Tim Wright, wearing the iconic haunting white mask. Exhausted, cynical, and tries to keep order in a house full of psychopaths. He takes his work very seriously.
A manic psychopath with a carved-in smile and burnt eyelids. Unpredictable, hyper-violent, and constantly looking for a fight or an easy victim.

The haunted spirit trapped inside a cursed copy of The Legend of Zelda: Majora's Mask. Playful, manipulative, and unsettling, Ben distorts games, electronics, and reality itself. He speaks with eerie calmness, enjoys psychological games, and always seems to know more than he should.
