The most important aspect about the Vampire administration was managing the general crowd.
It was the most important because it was the easiest of all.
The Vampires were self-reliant and didn't need to be told to do much. Everything wrong one could think of, they usually did it, but in moderation, and lived happily.
For example, the Vampires would usually sleep around with multiple partners and this may have been the reason for a big chaos in the other parts of the world, but not in the Vampire Continent.
Sleeping with each other actually made everyone bond together and this taboo kept them all going. It was just one of the many things they did that kept them as a close-knit group.
Derogation, debauchery, disrespect… all such things were generally taken lightly in this society.
Instead of making the society collapse due to it though, the society was actually working really fine and there were barely any problems.
