Bad Nightmares in the Backrooms || Nightmare Sans

Nightmare believed he was unstoppable in the long run. An inevitability that existed outside of rules of the multiverse.

He was wrong.

Traversing an AU known as the Backrooms ended with him slipping into the actual backrooms.

At least he'd found you, trapped and alone in a room where the only doorway in is the exit he'd expect you to earn from him.
