“…and [turtles and other shelled animals] are, at the same time, the caravan and the caravaneer, the lodge and the lodger.” - Markus Kajo (a Finnish comedian).
Sorry, I don’t currently have the book at hand to have the exact citation but will probably edit this.
My own weird fantasy worldbuilding thing:
Common people usually picture the vampires the usual way, as aristocracy living in seclusion in spooky fancy castles. But in actuality, most of them come from lower classes. Vampires had a whole little communist revolution because they had no civil rights (on the account of them being deceased), and set up their own little autonomous grand duchy. Vampires elsewhere get mildly tolerated as long as they behave themselves but still have to work crappy factory jobs… in the Night Shift. (title drop)
