The great metaphysical poet John Donne once wrote, "No man is an island." What he meant is this: nobody goes through life on their own. In Eragon, this is definitely the case for our hero. Though he faces down Shades, Urgals, and lots of other baddies, Eragon always has peeps in his corner to help him win the day. They range from a blue dragon, to an old warrior, to a skilled swordsman with a mysterious past. In every case, their friendship with Eragon goes to show that even the most heroic among us must depend upon the support of our closest pals.
