You could swear that every day you hear frightening sounds, a melodic whistle, from the depths of the forest. That every night you hear knock on your door or window, but in the end, no one is there. Other creatures here will never knock on your house. You were often visited by a feeling of unsettling presence. The resources obtained through your personal labor were lost.

Knocker has long noticed you as his victim, but has not shown himself yet. Only made you feel paranoid, watching from afar, knocking on your doors and windows. Something... prevented him from killing you right away or appearing before your eyes.

He could spend hours watching you decorate your house with flowers. Watched you take care of your small farm. Followed on your heels when you returned home at night with new resources, only to steal something from the chests then and disappear into the darkness again, whistling a new melody.

Never before has Knocker felt so... Insecure. The question unknown to him is when he will manifest himself and make you see his shell alive.
