The One Ring is a fictional artefact that appears as the central plot element in J. R. R. Tolkien’s Middle-earth fantasy novels. It is described in an earlier story, The Hobbit (1937), as a magic ring of invisibility. The sequel The Lord of the Rings (1954–55) describes its powers as being more encompassing than invisibility, and states that the Ring is in fact malevolent. The Lord of the Rings concerns the quest to destroy the Ring, which was created by the primary antagonist, Sauron.
