Hubertus is a Knight of Ritterheim, who served under Andreas von Drachenberg. Like Andreas, he wears heavy mail, fights with sword and spear, and displays the Knight's chess knight device on his shield and over his armor. He also rides a warhorse, and like the other knights, possesses the facility to dismiss or summon it when he needs to. And he can perform certain magic, projecting a light-like, searing beam from his sword during combat. Unlike Sigismund and Andreas, Hubertus was not able to speak the Norik tongue. Hubertus, along with his comrade Dietlieb, tried to take Chonkorchuk prisoner after their team had captured the rest of his companions, but his invisibility saved him, and he later was able to negotiate his freedom with Andreas. Subsequently, Hubertus, along with Andreas and Franz, followed Khurshid ibn Ali and Plamen as they circled around Baba Yaga's compound, testing her defenses, and looking for a way in. When guardian skulls assaulted the pair with balls of fire, Hubertus helped his master heal them so they could continue their work. But Plamen and Khurshid then managed to slip away. It was the last time any of the Yokels had seen or heard of Hubertus. His current whereabouts are unknown.
