Someone in the
vampire life style who has a physical thirst, need, craving for blood (which is non-erotic in nature) in more
significant quantity than is generally required or desired by other blood-drinkers. Sanguinarians (a word from the Latin root "sanguinarius", meaning "bloodthirsty") apparently do not get the benefits from pranic energy, or else they are unable to feed psychically like psi and energy vampires, for whom blood and pranic energy are apparently
interchangeable.
