Many favoured priests of the Order of the Silver Hammer in the Sigmarite cult bear Jade Amulets. Most are ancient, and have been passed from priest to priest for centuries. It is believed that Jade Amulets contain fragments of the Jade Griffon, an artefact of extreme power and importance to the Sigmarite cult. They are typically carved into the shape of twin-tailed comets or a griffon claws, and some are permanently attached to intricately carved breastplates. Jade Amulets are occasionally presented by the Grand Theogonist as a reward for great services to the Empire and the Cult of Sigmar.
