Everyone thinks Archetypes represent some sort of aspect of the Hero's Journey. The Protagonist, the Sword-Weilder, the Doorstop, and the Gateway Guardian. They don't. Archetypes function as analagoies to forces and drives within our own minds. The Protagonist represents our tendency towards Initiating action. The Antagonist represents Reticence within the mind. Once you see characters as parts of a Story Mind these other names seem silly and made-up.
