The Jeweled Collar

 The Jeweled Collar is an obviously Syrnth artifact, in the style of a collar or choker about the size of a person's neck, covered in gemstones and with a square indentation in the back.

If someone places the collar around their neck, it will automatically snap shut and can only be removed by unlocking it with the box. The gems will begin to glow again once it is  fastened. Within a few seconds, the wearer will feel a dull numbing in their throat can no longer make any sounds beyond exhalations, hisses and coughs. The wearer will remain  effectively mute until the collar is removed. The collar can only be removed if The Music Box is fitted into the indentation in the back of the collar.
