You know you've heard it. Deep in the gathering gloom of your room at night. The almost imperceptable sound of creaking. The almost silent footfalls of something unseen.
You know you've felt it. The breath on the back of your neck. The icy chill that raises the hairs on your arms. The feeling of being watched...by something...on the other side of the room.
You know you've seen it. The figure standing in the corner that is blacker than black. That thing that swallows every ounce of light in the room. Could it swallow your very soul?
