Middle Earth actually had a second set of well-known rings. Although not as powerful at the main set, these were certainly nothing to shake a finger at. Silver in color, they, like their gold counterparts were usable by anyone. Their only real power was the ability to provide near instant long-distance communication. At first this would seem good. Unfortunately anyone with a ring had a chance to intercept the message. Those that knew, called it "The Tolkien Ring Network"
