King of Angmar
The Witch-king of Angmar
The Witch-king was the greatest of the Nine Ringwraiths, a king and sorcerer of the Second Age who took one of the Nine Rings and became Sauron's deadliest servant. As King of Angmar he destroyed the North-kingdom of Arnor; as Lord of Minas Morgul he ended the line of Gondor's kings; and as the Black Captain he led the hunt for the Ring and the assault on Minas Tirith, where Éowyn and Merry fulfilled Glorfindel's prophecy and destroyed him.
