Baron Levente has fallen under a terrible disease. Bishop Konrád, his chief advisor, insists that it is not a natural illness, but a curse. In the 13th century, the Magyars are rebuilding the Kingdom of Hungary, devastated by the Mongols' invasions. But not everyone has altruistic intentions; someone has fixed his gaze on the Carpathian Mountains, and found the perfect way to increase his power without arousing suspicion. Meanwhile, the royal court summons knight Rodger Clement to discuss the situation. Rumors tell of a cure in the depths of the Bükk Mountains, and Clement is the only one who can stand up to the task. His resolve, blood and sword are at the service of his lord, and he will do anything in his power to save him... even if it means giving his own life.
