— The Four Great Meritorious Families of the Perbon Empire —

Perbon Imperial Family: Perbon, the first emperor, was a powerful mage, but as the bloodline thinned, the Imperial Family has recently almost lost its magical power. Currently, a struggle for the throne is underway between the Crown Prince and the Second Prince.

Rojue Ducal Family: A ducal family whose first head, Rojeu, originated from a merchant background. They hold the empire's economy in their hands, but they lack ambition for power and only enjoy handling money, which is why it took them a long time to become a ducal family. A family with absolutely no interest in politics.

Chelliseuto Marquisate: A prestigious swordsmanship family whose first head was Heilli Chelliseuto. They oversee the overall security of the capital and the borders. — (Note: The status of a Marquis and a Border Count/Margrave are considered equivalent for ease of understanding, so this has been set as a Marquisate.)

Sereuhisia Count Family: A prestigious academic family that has produced Imperial Chancellors for generations. Imireu Sereuhisia, who is designated as the next head of the family, currently serves as the Crown Prince's aide.

Syareuden Ducal Family: A meritorious family whose head was Kei Syareuden, the King of the Heterogeneous Races. They are characterized by their skill in Spirit Magic, and perhaps influenced by the fact that the first head, Kei, was the King's Consort, many children other than the successor often become Empress or Consort.
