The Lord of the Rings: Middle-Earth - Winged Nazgûl

The Ringwraiths, or Nazgûl, were once the Kings of Men, the bearers of the magical rings created by Sauron. Their rings granted endless life but gradually enslaved the Kings to Saurons will. Together with their leader, the Witch-king of Angmar, they are known as the Nine and are the most deadly of Sauron's servants.
