Idris Tytania, at age 24, is the youngest and newest of the four dukes in line for succeeding as the head of the clan. Intelligent and cruel, he murdered the Emperor's secretary claiming he was a 'rebel' and subsequently purged all of his supporters. Besides a duke, he is also commander of the royal guard in charge of protecting Uraniborg and, after certain events, is appointed in an even higher position. He holds a grudge against all the other dukes, especially Jouslain. His brother, aged 17, appears in one episode. He also has at least two sisters.
