The One Ring, also known as the Ruling Ring, Master Ring, Ring of Power, or Isildur's Bane, was one of the most powerful artifacts in Middle-Earth created by the Dark Lord Sauron in the fires of Mount Doom during the Second Age. His intent was to concentrate and enlarge his own power, and to exercise control over the other Rings of Power, which had been made by Celebrimbor and his people with Sauron's assistance. In this way, he hoped to gain lordship over the Elves and all of the other races in Middle-Earth. To accomplish this end, Sauron knew that the One Ring would need to contain an extraordinary amount of power. As such, he concentrated within the Ring a great part of his own inherent power, thus a part of him is within it. In this way, Sauron's fate became bound to that of the One Ring. If it were damaged or destroyed, the same would happen to the power Sauron put into it.
