Minas Morgul
"The Lord of the Rings" calls them Sauron's "most terrible servants". Their leader, known as the Lord of the Nazgûl or the Witch-King of Angmar, had once been the King of Angmar. At the end of the Third Age, their main stronghold was the city of Minas Morgul at the entrance to Sauron's realm, Mordor. They dress entirely in black. In their early forays, they ride on black horses; later they ride flying monsters, which Tolkien described as "pterodactylic". Their main weapon is terror, though in their pursuit of the Ring-bearer Frodo, their leader uses a Morgul-knife which would reduce its victim to a wraith, and they carry ordinary swords. In his final battle, the Lord of the Nazgûl attacks Éowyn with a mace. The hobbit Merry stabs him with an ancient enchanted Númenórean blade, allowing Éowyn to kill him with her sword.
