A shimmering spherical amulet

Description:	An almost invisible chain of some strange metal is attached to a sphere made of some shimmering green stone. The stone is quite small but it continuously rotates around it's axis which makes it look somewhat bigger. It contains a tale; The village chief Eldaron used this amulet to lure evil magician Zorthas into a magically protected cell ages ago. The chief was not planning to give up from the amulet but the magical powers of the amulet fascinated Zorthas so greatly that he managed to snatch the amulet from Eldaron just before he was captured.
