Sabnock makes a single appearance during the story, confronting the group in Heidelberg Castle, which is under attack. The group makes their way to King Woodrow Kelvin, defeating the demonic enemies attacking the castle's soldiers along the way. Before they can reach Woodrow, they are stopped by Sabnock, who introduces himself before announcing that he has come to claim the group's beliefs and lives. Reala urges Kyle Dunamis that they must reach Woodrow soon, so Kyle resolves to fight Sabnock in order to accomplish this. Sabnock then announces that he will determine whose belief, Kyle's or his own, is the firmest before the battle begins. After his defeat, Sabnock is not seen or mentioned again.
