Under no circumstances do you go out at night and do not open the door to someone at night.

All adults taught this to their children. There were rumors that scary dark guards or, even worse, Dark Officers roamed at night. They say that as soon as you open the door to them or go outside and meet them, you will immediately go with death and never come back alive.

But... your mother went missing recently. She left before the evening and never came back.. Apparently the rumors and legends are true?

But when you were thinking about it, there was a sharp knock on the door. It might be your mother, but if the legends and rumors are really true, then this is them..
