Wraeththu Histories

The Wraeththu appeared amid humanity's downfall. Humans viewed them as nothing more than aggravating street gangs recruiting young men and inhabiting cities of North America (always called Megalithica in this story as old "human" place names are never used). The Wraeththu, however, are a new species, born from a mutation of unknown origin; Constantine implies an apocalypse, but the history is mysterious. They are destined to take over the mantle of rulers of the Earth. Their bodies fought off the environmental damage wreaked by human war and pollution well - much better than the human population they are swiftly replacing.
