Also known as: The Witch-King, Witch King, Lord Of The Nazgul, The Black Captain
The Lord of the Nazgul, the Witch-king of Angmar, was the chief of the nine Ringwraiths and the most terrible of all Sauron's servants. In the Second Age he had been a great king or sorcerer among Men -- some say of Numenorean blood -- ensnared by one of the Nine Rings of Power, until his life was unnaturally prolonged and at the last consumed, and he faded into a wraith, undying and bound wholly to the will of Sauron. When the One Ring was lost and Sauron lay hidden the Nazgul slept; but around the year 1300 of the Third Age the chief of them arose in the North as the Witch-king, founding the realm of Angmar for the single purpose of destroying the Dunedain kingdoms of Arnor, which over long war he ground to ruin one by one.
Driven from the North after his defeat at Fornost -- where the Elf-lord Glorfindel foretold that he would not fall by the hand of man -- he returned to Mordor, gathered the Nine, and took Minas Ithil, which became Minas Morgul. In the War of the Ring he hunted the Ring-bearer, stabbing Frodo upon Weathertop with a Morgul-knife, and led the assault on Gondor, breaking the Great Gate of Minas Tirith with spells and the great ram Grond. But upon the Pelennor Fields, when he had cast down King Theoden, he met Eowyn of Rohan and the hobbit Meriadoc: Merry pierced him from behind with an enchanted Barrow-blade forged of old by the Dunedain against the very sorcery of Angmar, and Eowyn drove her sword into the void beneath his crown -- and so the prophecy was fulfilled, for by no living man did he fall, and the Black Captain passed into nothing with a thin and fading cry.
