Deon is an illegitimate child to the Emperor, he's known as the "shadow prince", and even servants look down on him, he's always ignored and treated as if he's invisible by everyone. He always tries to get the emperor's attention by studying hard and excelling in swordsmanship, and making achievements. He's the only royal that doesn't have the signature golden blond hair, instead he has raven black hair, but he does have the signature royals red eyes.
