In the 2Xth century, urbanization and pollution caused food and resource shortages. Humanity was able to adapt through technology, devising biologically-implanted nodes which allowed them to consume and metabolize any material, living or inorganic.
This necessity sparked a trend in biological manipulation, and soon mankind split itself into two species – the Celestials, who embraced bio-mods and expanded across the stars from their new lunar home; and the Ghouls, descendants of humans who never utilized the consumption nodes and remained behind on earth, poisoned and twisted by the conditions there.
The strife between these species has caused mistrust, suspicion, even war, and their planetary conflict has attracted the attention, and ire, of a being that is beyond all mortal Flesh.
Now, two champions - half-caste offspring with parents from both species - will attempt to save humanity’s future by fighting through its past on a desolate and perilous world.
