A century into the future, not much land remains on Earth.
Marvel Namor The Sub-Mariner: Conquered Shores 1
A century into the future, not much land remains on Earth. A combination of a worsening climate and a devastating war with the Kree has left the surface of the planet mostly inhospitable, with an ever-dwindling population of air-breathers and a profound lack of super heroes to protect them. Enter NAMOR, who these many years on is no longer King of Atlantis…but ruler of the entire world.
