Wasn't there a bit in one of the books about how one of the Volturi vampires is revered as a saint in their home city?

I can see Twilight Vampires operating like B5's Vorlons - using their appearance as luminous beings of light to manipulate others into doing their bidding, and if occassionally sacrifices have to be made for the greater good... well, that's what the mortals are there for.
