The Soil Ghosts are a mutant race whose bodies metamorphosized from the biochemical annihilation of Estancia. Though little is known about these reclusive mutants, governments typically brand them as dangerous beasts and scapegoat them for deficiencies wrought by their own corrupt regimes. Gray Zone merchants, on the other hand, frequently speak of trading with gentle tribesmen devout in their faith to pacifist spirituality. Wandering the Estancia Gray Zone in hundreds of nomadic tribes, Soil Ghosts trek across the barren deserts, sowing mysterious seedlings one dune after another to no discernible effect. Nothing has ever sprouted from their efforts, yet they persist religiously with unflinching determination, all the while assembling innovative vehicles and SAs from scrap materials scavenged across the Gray Zones.
