Julius

Prince Julius appears out of nowhere as the King039s stepson and thus Ludwig039s stepbrother. This is however a mere hoax plotted by his quotmotherquot 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 Ludwig039s protection in the end. Source: Wikipedia
