Arwen, an elf and Strider's betrothed, comes to Frodo's aid, rescuing him and incapacitating the Nazgûl. “Come and claim him!” She takes him to Rivendell, where he is healed. Frodo meets Gandalf, who escaped Isengard with help from Gwaihir, a giant eagle. Arwen's father, Lord Elrond, holds a council that decides the Ring must be destroyed in Mount Doom. While the members argue, Frodo volunteers to take the Ring, accompanied by Gandalf, Sam, Merry, Pippin, elf Legolas, dwarf Gimli, Boromir of Gondor, and Strider, who is revealed to be Aragorn, Isildur's heir and the rightful King of Gondor. Bilbo gives Frodo his sword, Sting. The Fellowship of the Ring sets off.
