A tool in every psychic Vampyre’s arsenal that often goes unused is the Phylactery, which Father Sebastiaan, in his Black Veils, refers to as a potentially endless source of energy for the Vampyre to draw from. In both magickal and religious traditions, the Phylactery is sometimes referred to as a reliquary, a soul jar or vase, or an amulet into which the practitioner places a piece of themselves.
