Beware the Nine Nazgul riders, The Nazgul, or Ringwraiths, were Sauron's most terrible servants. They were originally mortal Men. Sauron gave them the Nine Rings of Power in order to enslave them to his will and they became Wraiths.
At first the Men who received the Nine Rings used them to gain power and wealth for themselves. They became great kings, sorcerers, and warriors. The Nine Rings made the Men invisible and prolonged their lives.
But eventually, the Men bearing the Nine Rings fell completely under the control of Sauron. They could not disobey him and no longer had wills of their own. Some of the Men were quickly enslaved, while others who had greater native strength or goodness took longer.
The Nazgul were condemned to exist only in the Wraith-world. Their lives were stretched out until their very existence was torture. They were permanently invisible except when they wore black robes to give themselves a visible shape. Sauron and anyone who wore the One Ring could see them in their Wraith forms, as pale figures with burning eyes, grey hair, grey and white robes, and silver helms.
Beware the Nine Nazgul riders.
