Similar to every "known" race spread throughout the charted world after the occurrence of the astronomical phenomenon that was known as the Emergence, the Vampire Race, even before they were transported against their will in an unknown world of Earth, had already an established societal hierarchy, divided into Twelve Vampire Clans.
Every Vampire Clan was ruled by a Vampire Lord, and under the Vampire Lord was a Vampire Grand Duke; then there exists the Vampire Archduke, Vampire Duke, Vampire Marquis, Vampire Earl, Vampire Viscount, and Vampire Baron.
The above-mentioned, except with the existence of either a Vampire Princess or Vampire Prince, depending on which Vampire Clan they belong to, was the royalty or nobility occupying the high status of the Vampire Race.
