精靈三戒
Later, someone naming himself "Annatar" arrives in Eregion. He appears to be an Elf, and claims he has been sent by the Valar to share his wisdom and skills in ring-craft and jewelry for the benefit of all Middle-earth; but in fact he is the Dark Lord Sauron in disguise. Annatar provides valuable and seemingly benevolent guidance and instruction to Celebrimbor and the smiths of Eregion, and they began making the Rings of Power for the rulers of Middle-earth—seven for the Dwarf-lords and nine for Men. Secretly, without Sauron's knowledge, Celebrimbor also forges three rings for the Elves, the greatest and fairest of the Rings of Power. The Three Rings are thus free of Sauron's corrupting influence.
