<P> It is not clear whether the Nazgûl continued to wear their rings . Tolkien says both "the Nine the Nazgûl keep" and that Sauron had gathered the Nine to himself, though in the latter case his meaning may be metaphorical . When the Nazgûl are destroyed, no mention is made of their rings . </P> <P> Only two of the Nazgûl are identified in the texts: the Witch - king of Angmar was the leader of the nine, and his second in command was Khamûl, an Easterling . Khamûl is the only Nazgûl identified by name . Three of the Nine were Númenórean . </P> <P> Also in the Second Age Sauron gave the Seven to various Dwarf - lords (though the Dwarves of Moria maintained a tradition that the ring given to Durin III came directly from the Elven smiths). Gandalf mentions a rumour that the seven hoards of the dwarves began each with a single golden ring, and although the Dwarves used their rings to increase their treasure, Tolkien does not explain how the rings accomplished this (save for a reference that the rings "need gold to breed gold"). The main power of the Seven on their wearers was to excite their sense of avarice . The wearers did not become invisible, did not get extended life - spans, nor succumb directly to Sauron's control--though he could still influence them to anger and greed . </P> <P> Over the years, Sauron recovered three rings from the Dwarves, the last from Thráin II during his final captivity in Dol Guldur some years before the beginning of The Hobbit . The remaining four, according to Gandalf, were destroyed by dragons . </P>
