Nazgûl

The Nazgûl, also known as the Black Riders, were nine men who were corrupted by the power of the One Ring. They became immortal wraiths, bound to Sauron's service and completely under his control. Their leader, the Witch-king of Angmar, was once the King of Angmar in the north of Eriador. The Nazgûl were feared throughout Middle-earth. They rode on black horses and wore black armor. Their faces were hidden by black hoods, and their eyes were glowing red. They were said to be able to strike terror into the hearts of their enemies. The Nazgûl were Sauron's most terrible servants. They were tasked with hunting down the One Ring and bringing it back to their master. They pursued the Ring-bearer Frodo Baggins throughout Middle-earth, but they were ultimately defeated at the Battle of Pelennor Fields. The Nazgûl are a powerful and terrifying force in Middle-earth. They are a reminder of the dark power of Sauron, and they are a threat to all who would oppose him.
