The Zone Continuum (comics)

The Zones- extra dimensional planes of existence directly corresponding with our own world, and populated by an ancient race known only as the Natives. As mankind threatens its own existence with warfare and pollution, so too are the Zones affected, shrinking ever smaller as a result of the havoc wrought upon Earth. Now, the livable space of Manhattan's Zone 27 grows dangerously constrained, forcing the Natives ever higher into the skyline, and two nigh-immortal champions compete in an invisible war for dominance--but the consequences of their conflict could shatter not only the stability of the Zone Continuum, but also that of reality itself!
