One of my suppliers found this piece. He said that it may be a machine for concentrating energy from crystals, but that the crystal had clearly been long since removed and some damage sustained to the talisman. There are no markings or other indications of where this piece is from or who made it. There is some type of mechanism inside, rusted. Lab testing reveals that the casing is made of fine silver, and there are small patches of 24k gold on the surface. The interior machinery consists of gold-filled silver and vanadium/tungsten alloys. After some experimentation, it appears this piece is too far damaged to repair back to it's original working state. There appears to be a critical integration between the machinery and crystal that we have been unable to activate. An ongoing mystery, this piece.
