"We are required to consume a measure of human blood to survive."

"That is rather parasitic of you," Rutile says evenly, their expression neutral - but the speed at which their questions come betrays their interest. "But fascinating all the same. What does it mean to be undead? How does a human achieve that? Are vampires another species, technically? Surely they couldn't be, if some of you are formerly human - but then how could you be born? What were your parents?"

The tirade of questions is almost rhetorical.
