Khamûl

"'Shire...Baggins...'"-Khamul's one line in the films.Khamul is a Nazgul, one of nine, and in fact second-in-command of the group behind the Witch-King of Angmar. In life, he was a king of the Easterlings, and now serves Sauron dutifully after being corrupted by one of the nine rings of power Sauron offered to the great kings of men. It is he who goes to the Shire and the surrounding areas looking for the One Ring and the "Baggins" who possess it. He fails to acquire the Ring however, and he and his fellow Nazgul are redirected through the efforts of Aragorn and Glorfindel (or Arwen, in the movies). Like his fellow Nazgul, he aided Sauron's Orc and mannish hordes in their efforts against the kingdom of Gondor, and was along with the other Nazgul destroyed when Sauron and the One Ring were (though Gandalf believes they were sucked into the Void with him, meaning they may return for the final battle of Dagor Dagorath).
