Vampirism is a physical condition wherein the afflicted person's body does not either produce enough, or none at all, of the essential energies to maintain a proper balance of physical, mental and emotional well-being and must, therefore, turn to outside sources to attain these energies. These sources range from blood to psychic energy to empathic energy to elemental energy to the ambient negative energy present every day to eclectic mixes of any of the above sources.
