Bilbo is Frodo’s cousin, and his adventures to the Misty Mountains many years ago led to his friendship with Gandalf. A previous bearer of the Ring, Bilbo resides in Rivendell as Elrond’s guest until the War of the Ring, when his surprising long life and health begin to fade. He leaves Middle-earth on the ship with Elrond, Gandalf, Galadriel, and Frodo.
