Living inside a vampire’s territory actually isn’t all that
bad. Vampires want the humans living in their domain to be healthy, safe, and content.
This is their food supply after all.
Healthy and safe, I feel are self-explanatory.
As for content? Well, first of all, content people normally don’t
form mobs and they also don’t move. A city that has all the things necessary for
a good life will attract more humans thus increasing the herd.
And well, surely, you’ve heard that happy cows make better milk?
