Three Rings
Commentators have observed that the Three Rings enabled the Elves to halt the passage of time within their realms, especially in Lothlórien where Galadriel wielded Nenya. Others have noted that their power was benevolent, in sharp contrast to the One Ring, and could be used to protect and to heal; and that Tolkien uses the Three Rings to elaborate the angelic and sacrificial aspects of the Elves in the battle between good and evil in the War of the Ring.
