Winking Eyes of Rhauron

The Winking Eyes of Rhauron were numerous magically enchanted gemstones which, when touched bare-handed, would melt into the handler's hand and compel the person to attempt to assassinate a target. The name of the stones was apparently a bard's attempt to get even with an innkeeper known as Rhauron who had cheated him out of money. The true name of the enchanter was unknown. In reality, the gems were enchanted by a person in Returned Abeir who sought to assassinate persons who had fled to Faerûn.

Description
All the gems were approximately the size of a large man's thumb and could be sapphires, emeralds, diamonds or rubies.
