The older grows to be a selfish, slovenly man, who inherits the castle at his father's death and becomes ruler over the formerly happy villagers.

In this way he hopes to not only avoid the prophecy, but also escape consequences of his other criminal deeds and obtain marriage to a local girl of the nobility...
