Trivia

 * The Emperor is supposedly the father of the Narnia's Messiah which is Aslan. This would presumably make him represent God the Father.
 * The Emperor is only mentioned in the Lion, the Witch and the Wardrobe, once in Prince Caspian and once in The Horse and His Boy . In later novels his attributes are embodied in Aslan. Whether or not this change was deliberate on Lewis' part, his status is unclear by the end of the Last Battle.
 * The Emperor has yet to be mentioned in any of the Narnia films.
