For a short period while writing a background lore behind the ring, Tolkien was struggling with the idea that the Elven rings must be given a special status—somehow linked to the One Ring, and thus endangered by it, but also unsullied that it would involve them having no direct connection with Sauron. By the time he was writing the chapter The Mirror of Galadriel, Tolkien resolved to write that the Seven and the Nine were made by the Elven-smiths of Eregion under Sauron's guidance; but the Three were made by Celebrimbor alone, while Sauron secretly made the One, which has the power over the others, and once the Elves have finally realised what his deception, they immediately hid the Three. He also drafted an idea that upon the destruction of the One, the Three will be freed from being bound to it, but he ultimately decided to discard it. Tolkien's subsequent posthumous works such as The Silmarillion, Unfinished Tales and The History of Middle-earth also offer additional material relating to creation of the Rings.
