Consider: The Three Elven Rings Are Evil
The Three Elven Rings of Tolkien-- Narya, Nenya and Vilya-- were fashioned by Celebrimbor but never touched by Annatar (Sauron) himself. However, they were crafted by his arts. The greatest fear of Elvenkind during the LotR was that Sauron would regain the One Ring, and expose all the Three had to hide. How could Sauron do this? By the essential connection between all the Rings of Power: the power of Sauron himself.
The Three are supported by the power of the Ring Lord, and they stand or fall by him. The Three do not fade after the War of the Ring because the Elves said "Yey! We won! Lates, Middle Earth. We're going home now and the Three are being put out because their mission is done." No. The Three fade because the force behind their power, Sauron, is gone.
At the end of LotR, the keepers of the Three (Elrond, Galadriel and Gandalf) depart for the Uttermost West, sporting their swag as they go. But why would Valinor accept the arrival of these tokens, so tainted as they are by the premiere lieutenant of Morgoth? The final act in the War of the Ring was when the West rejected the spirit of Curunir (Saurman) after his death at Bag End. Yet Saurman himself never touched or used the Three, but coveted the One. So the wielders of the Three are permitted to sail over Sea with the tainted Rings on their persons, and the traitor who never used any Ring is rejected by the West?
A Plot Hole, Professor Tolkien?
