I come from a small town near the Schwarzwald (Germany) the myth goes that if you go into the forest at night you will see the GroßMann literally means tall man he is our version of slender man except WAY older he has no face and has shadows coming out of his back, he also brings [demise] and sorrow. The scariest part is that he remains consistent throughout the centuries and is even found in German books and paintings. Großman has been mainly forgotten but he is also known as schlankerman (skinny man) I tried finding a Wikipedia page for it but I can't srry guys. If ur intrested u can search up any of the names above or "Der Erlking" a poem by Goethe describing a similar figure or you can search up Hans baldungs painting
He supposedly drew the großman and later the extra limbs were erased but X-rays supposedly reveal them.
