The matt blue vicarious sigil is a small artefact token of ceramic embossed with the image of two shaking hands. By attaching the sigil to a paired artefact (such as earrings of Sinope or a Bag of sharing), the owner may change the ownership of the partnered item without charge. The sigil becomes attached forever but partnership of the paired artefact may be changed once a year. The sigils are sold at the Shop of Wonders in Delos.
