|“||A magical, ancient race: the Moroi. The Moroi don't wear black capes, turn into bats, or sleep in coffins. Daylight annoys yet doesn't kill them and they don't sparkle either. But yes, like most creatures with fangs, the Moroi live off blood. But they don't live forever. That's why they need us.||”|
