 The vis bulla is a holy strength amulet, a tiny silver cross forged from a small vein beneath the mountain of Golgatha and steeped in holy water.It provides protection, strength, speed, and fast-healing capability for the Venator.There are no more than two hundred Venators world wide at any given time; they fall in far-flung branches of the Gardella family throughout all corners of the earth–often unaware of the family legacy until the five dreams, and the subsequent visit by the mentor.
