One of the Nazgûl or Ringwraiths. Khamûl was an Easterling King who came under Sauron's influence during the Second Age of the Sun and was given one of the Nine Rings of Mortal Men.

Sometimes called the Black Easterling or the Shadow of the East, Khamûl was second only to the Witch-king in rank among the Nazgûl.

He fought for Sauron until the Ring Lord was overthrown at the end of the Second Age.

In the Third Age, Khamûl appears to have been Sauron's chief lieutenant in Mirkwood from about 1100.Certainly, after 2951, Khamûl was the master of Dol Guldur.

During the Quest of the Ring, Khamûl was the Dark Rider who entered Hobbiton, and then pursued Frodo Baggins and nearly caught him at Bucklebury Ferry.

Through the War of the Ring, the Ringwraiths brought despair to the enemies of Sauron. After the destruction of the Witch-king, Khamûl became the new captain of the Ringwraiths.

Khamûl was among the eight surviving Ringwraiths who flew on their Winged Beasts into the Battle before the Morannon.

However, all their evil power came to nothing, for once the One Ring was destroyed in the fires of Mount Doom, all of Sauron's empire was ended. Khamûl and the other Wraiths were sent shrieking into the shadows forever after.
