The Will of a Wizard

When Frodo volunteers to take the One Ring of Power to the fires of Orodruin in Mordor, Gandalf is reminded of another Hobbit who risked his life to resist the powers of evil. One-shot, based on the Council of the Ring (Fellowship of the Ring) and a scene in The Battle of the Five Armies (therefore there may be spoilers if you have not yet watched the movie). Angst and friendship.
