Last Riding of the Keepers
From Tolkien Gateway
The Riding of the Three Keepers westward through the Shire to the Grey Havens, from where they set sail into the West, never to return to Middle-earth. The Keepers were Elrond, Galadriel and Gandalf, and they were joined on their White Ship by the two famous hobbit Ring-bearers, Bilbo and Frodo Baggins.
