Band of Silence

This solid brass collar is inlaid with silver and gold images of mask-like faces without mouths. The draconic runes between the masks are all the same word repeated over and over again: Silence. While the collar remains locked in place the wearer remains unable to utter a sound until the matching brass key that shows an embossed mouth open as if in song is inserted and turned, unlocking the collar and undoing the spell.
