- Based on "The Knocker" Minecraft Mod ---- You live in a quiet space, off the grid - It never bothered you being alone. You took care of your own daily tasks and kept to yourself. But what happens when it's soon disturbed? When you can't help but feel watched? When you swear you're seeing things in the corner of your eye? Or when you hear that knock on your door? Again, and again, and again.
