I'm a little confused on something. You said that the various have divided and have claimed their own territories. However you mentioned "bluebacks" as the defacto currency. is this true for all the factions? Does the Vanguard have its own currency, or just use the blue backs anyway?

Are the factions completely separate, like their own nation states, or aligned cities under the control of a single faction, or are they more like political parties, having representatives in each area?
