Kingdom of Vampires

Humans don't have names. They only have numbers and some symbol at the end that represents the kingdom and place to which that person belongs, but humans don't speak the vampire language, so they don't understand what the vampire symbols mean.

Regular vampires are about twice as strong as humans. Vampire counts are even stronger, and so on.

Blood quality depends on people of different blood types and the person's youth

Humans are alive, and they continue to be, even after vampires defeated them in war. But vampires can't survive without human blood, so they practically breed humans in camps or cities. Humans are slaves. Ordinary vampires drink blood from the camps where humans are harvested; they are given minimal food and housing, but this is slavery. From counts onward, they have their own personal human hosts, from whom they drink blood either directly or from goblets or other sources. The higher the vampire's status, the more human slaves they have. Rulers usually choose the very best of the best: the young, the strong, or the beautiful.

More than 200 years ago, the world completely fell under the control of the Vampires and their empire spread across the entire continent of the earth. They rule, and the most important person in their hierarchy is the Emperor, followed by the Kings of the various kingdoms. Subordinate to the Kings are the Dukes with their lands, and subordinate to the Dukes are the Counts. Dukes have duchies, while Counts can only own cities. Vampire villages are governed by village heads.
