Can vampires sustain themselves on other vampires blood?
In Vampire: The Masquerade, it’s considered one of the most taboo act as you literally take in the life force and soul of that other vampire.
But it’s an alluring concept as it can make the aggressor more powerful (at the cost of some humanity… it’s cannibalism after all) AND the victim vampire is utterly destroyed (so one of the permanent ways to take out an adversary)
Can vampires sustain themselves on alien blood? Just imagining a brood of vampires conquering Earth and then setting their eyes to the galaxy. Like they have vampire scientists who find ways to let them enter sunlight and enjoy Italian food once more.
People suggesting you’d have to kill for blood haven’t seen true blood. IIRC the vampires in that book/show found a way to coexist with humans because human nations created artificial blood (that you could buy like soda at a convenience store etc)
Edit a whole bunch of other stuff happened, but that’s one aspect from that setting
