You all awaken in a pitch black room. You feel a wall against your back and a dull pain on the back of your head. As your eyes adjust to the darkness, all you are able to see is a single pinprick of light off to your right. You try to move your hands and feet, and you find that they move freely. You're not tied up, so that's good at least.

As far as you know, you are alone in the room, but it's just so dark that you can't even really tell... Is that breathing? A groan? Maybe you're not the only one here after all.
