Em um rascunho descartado, Tolkien indicou que os [[Elfos (TCalaquendi]], como [[Glorfindel]], poderiam usar o poder de invisibilidade de um Anel para esolher aparecer ou no mundo físico ou invisível, sem existir nos dois ao mesmo tempo. Isso guarda semelhanças, e até pode ser uma possível explicação, sobre como Sauron e [[Tom Bombadil]] poderiam permanecer visíveis enquanto usavam o Um Anel.
 The Nine
Main article: Nazgûl
The Nine Rings caused Men wearing them to become invisible. They also extended the lifespans of Men who possessed them, although this eventually led to the Men becoming wraiths under Sauron's complete control. It is implied by Gandalf that all the Great Rings would have the same effects on Men, but Tolkien wrote that this was untrue of the Three and there are no instances of a Man bearing one of the Three.
The wraiths of the Men who received the Nine were the Nazgûl, the Ringwraiths, Sauron's most feared servants. None are mentioned specifically in The Lord of The Rings except their leader, the Witch-king of Angmar. His second-in-command is named in Unfinished Tales as Khamûl, the Black Easterling. What is known is that three of the nine Ringwraiths were originally 'great lords' of Númenor in the mid Second Age.
The Nine were held by the Nazgûl after the fall of Sauron at the end of the Second Age, and they went on to wreak great evil with their powers in the East and South of Middle-earth, as well as the kingdom of Angmar, which warred on and destroyed the Dúnedain in the North. Later, Sauron was said to have gathered the Nine to himself, but this could also be construed as having the Nazgûl close at hand, rather than physically having these rings at Barad-dûr as was certainly the case with the remaining Dwarf-rings.
