I was recently reading the latest book in The Vampire Chronicles, Prince Lestat and the Realms of Atlantis. After the many ups and all-too-frequent downs of the series, reading the new installments comes out of the same schadenfreude-y curiosity that presumably leads other people to watch the Kardashians: namely, wanting to know what on earth these disaster (non)humans are up to now.
One of the major worldbuilding developments in the most recent books has been, as one might guess from the title, the ascension of Lestat into a sort of mutually-agreed-upon rulership of the vampire community. Even Lestat has acquired some self-awareness, over the years; he knows that he is not going to have the attention span to attend to every issue of the community, and so he forms a court of vampiric elders from across the world. While this has the immediate benefit for the reader of putting all the major players of the series in one place to stand around and be beautiful at each other, it also lends a seriousness to Lestat’s rule. His princeship is not symbolic, and for the first time the vampire community is less an arbitrary group of metahumans connected only by the fluke of their condition and more of an organized nation. And that, of course, means there needs to be rules.
In an increasingly plugged in and hyper-vigilant world where the existence of vampires is a very poorly guarded secret, it’s more important than ever that vampires maintain a low profile. As part of this (and as part of the mentality that vampires are not inherently evil despite their predatory nature) they are expected to behave in reasonably moral ways.

Except for that whole “don’t turn children” rule. (via wikipedia)
Don’t kill; only take enough blood to sate your hunger. Don’t drink from innocents; only take blood from those who are clearly bad people (you know, like, sex traffickers, murderers, people who don’t use their turn signal). Don’t broadcast your existence to humans—a “do as I say, not as I do” rule given Lestat’s history—as this endangers the entire vampire community. However, despite the rather checkered history of how all these people actually became vampires, there don’t seem to be any rules forthcoming about who gets to be a vampire.
