Ostrheinsburg Castle rises high with the deep forests of Mittelberg in Germany behind it. Constructed by a renowned independent knight named Sir Stefan, this castle's defenses consisted of quadruple castle walls considered as being impregnable.

However, after sir Stefan was killed in a war, the remaining soldiers loyal to him were summarily executed and woman and children were taken away as slaves. After thieves plundered it thoroughly, this castle became a tragic ruin that reeked of death. It became a place where none dared to visit.
