Neither side has taken over this bit of 'No Man's Land', due to how wild this once-great superpower this was. People who live there live faraway from the cities if they're sane, alone or considering safety first. The states are either destroyed and barren, with no way to salvage it in the world's current state, or in a post-apocalyptic state.
Deadmen often go in, never to come out, whilst Undertakers try to keep the places busy with soldiers from normal armies patrolling the land mass.
