For almost as long as the Empire has existed, there have been the nobles - powerful individuals each with their own section of the Empire's land. Arranged in a heirarchy based on the different levels of territory administration, the nobles rank from the highest Archdukes and Archduchesses who have entire Regions, through Dukes and Duchesses with Provinces, Counts and Countesses with Counties, and the smallest Barons and Baronesses with cities. Each tier can only be appointed by the noble above it, sometimes requiring the consent of the Monarch and the Ruling Council.
Nobles generally have positions in the local government of the Provinces they have land in. On a national scale, Dukes and Duchesses have seats on the Ruling Council, and can be Ministers in the National Government.

Archdukes, Archduchesses, Dukes and Duchesses all hold the style of His/Her Grace, spoken to as Your Grace. Counts, Countesses, Barons and Baronesses all hold the style of Lord/Lady, spoken to as Your Lordship/Ladyship. However, if the noble holds an Imperial style (Imperial Highness or Majesty), this overrides the noble style. Knights and Dames usually hold their style of Sir / Madam along with their other styles.
