Of the Rings of Power, only the Three crafted by Celebrimbor were never touched nor sullied by the Dark Lord of Mordor. Having suspected Sauron's evil purposes, Celembrimbor gave them to three Elf-lords who hid them through the ages and used them to resist the Dark Lord's influence. Should he recover the One, Sauron will command all the Rings of Power, even the Three, and he will be able to undo all the good that the Elves had created with the Three. Fortunately, though, Sauron does not have the One, and he does not yet have the means to undo the works created from the Three.
