A post apocalyptic world where global warming went too far. Humanity is driven back into the shadows and to the underground where shade and coolness is bountiful. Those who stay outside face terrible mirages and hallucinations, driving many to insanity. Some humans thought that the terrible heat wave was the coming of a religious event, eventually spawning a malformed category of sub-humans that call themselves The Prometheans [ANOTHER NAME NEEDED] that wage war on the people who "remain in the dark." for not following their enlightened culture. We follow a small family, where the husband has joined SHADE, a military force with advanced technology equipped with ICE (Independent Cooling Environment) Packs, allowing for continued expeditions on the surface and to push back the heat.
