In Sunrise Empire, the title of Archduke is just below that of the Emperor and above that of princes and princesses. The Archdukes are considered the very first founding families that first followed the very first emperor of the empire. They are so powerful that they can literally ignore the members of the imperial family except for the Emperor.
And the Empire currently have three families of Archdukes. One of them is the Lionett Household which Garona belongs to, then there's the Everton Household and lastly, the Tudor Household. The three families are called the Empire's Spear, Sword and Shield respectively.
Lionnet Household are called the Shield because they are the one that guards the empire's border against the monsters from Forest of Despair, and on the other hand, the Everton Household and Tudor Household are the swords and spears of the empire towards the surrounding nations.
