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.
