Ondřej from Rohatka settled in Jenčov Castle, which he received from Margrave Karel for the services he had rendered him during the campaign in Italy. However, not everyone is excited about this state of affairs. What can possibly attract them to this insignificant commodity? And why do people have to die for it? They are iron ore deposits located on land belonging to Jenčov. And so the Crooked Burgrave Chval of Valdéra will stop at nothing to help him get those goods. He convinces King John of Luxembourg to invalidate the donation deed of his son Margrave Karl. Will Karel, whose influence and popularity in the kingdom is constantly rising, listen to his father?
