Julius

Prince Julius appears out of nowhere as the King's stepson, and thus Ludwig's stepbrother. This is, however, a mere hoax plotted by his "mother" Petronella, a witch craving for the title of queen. Mistaking Amalberga for Ludwig, he bears an extreme hatred towards him for most of the series, but it is actually revealed that he fell madly in love with him some times prior to the beginning of the story. Wielder of some potent witchcraft, he is allowed to stay under Ludwig's protection in the end.
