The Witch-king

The Witch-king is a powerful and malevolent sorcerer from J.R.R. Tolkien's Middle-earth legendarium, known as the Lord of the Nazgûl or Ringwraiths. As the chief servant of the Dark Lord Sauron, he is fearsome, nearly indestructible, and driven by a desire to dominate and spread evil. Wielding dark magic, he plays a central role in the war against the free peoples of Middle-earth, especially during the events of "The Lord of the Rings." His presence symbolizes ultimate evil, and his defeat marks a turning point in the struggle to defeat Sauron.
