USW: Tip the World Over on Its Side
The archetypes are the primordial characters embodied by avatars. Think of them as the Platonic ideal of a character, like Jungian archetypes or the major arcana of the Tarot — they could be the representation of the Father, the Mother, the Soldier, whatever. Think of all the archetypes and symbols that appear in folklore, religion, and stories; any of them might be archetypes out there somewhere.
Brian Lane claims the Archetypes were once living people, ascending into the Statosphere via the cosmic representative democracy that creates the Invisible Clergy. Once the Invisible Clergy hits 333 members, the universe resets and the cycle begins anew.
The Archetypes are the gods we make.
