Everyone who has seen the Lord of the Rings or The Hobbit trilogy knows that Gandalf is an unstoppable figure. He manages to persuade two of the most stubborn men in Middle Earth (the sick and poisoned mind of King Theoden of Rohan, and the paranoid and delusional Steward of Gondor Denethor) to let him intervene in their affairs, even when all of the treachery and darkness around them told them not to. Across both sets of books, Gandalf battles many enemies, slays many orcs, protects (and sadly loses) many friends, and he is the instigator of the two quests which, each in their own way, determine the fate of the entire world and all of its people.
