【Soil Ghosts】

The Soil Ghosts are a mutant race of desert nomads who trace their origins to the fallen Estancian Empire. Some scholars speculate that in addition to acid rains and radioactive pollution, Soil Ghost mutations also arose from the Estancian government’s experimental pesticide Wonderlizer, hastily developed plague vaccines and residues from Omanga’s biochemical attack.

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 dozens 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.

【Chief Koren】

Time-tested by decades of grueling hardship, Chief Koren guides his fellow Sahai tribesmen with a firm but gentle hand. As one of the first Soil Ghost mutants, he bears haunting memories of the early anti-mutant purges. Koren’s ferocity mellowed with age, and today the battle-seasoned rebel is a diplomatic elder who prepares for the worst but preaches for peace.

【Doeg】

Doeg is a remarkable navigator who never fails to find untapped resources. Though a heartthrob among the Soil Ghost maidens, he prefers the company of animals over other tribesmen – casting a spell over wildlife with his sweet harmonica. The only thing Doeg excels more at than music is hunting – claiming the Horn of the Ancient during an inter-tribal ritual contest.

【土鬼】

土鬼的祖先自來已倒台的伊斯坦西亞帝國，他們目前以遊牧形式在沙漠地區生活，身體都出現了不同程度的變異。有學者推論土鬼身體變異的原因，除了生活區域有重度酸雨污染和核污染，還有當年伊斯坦西亞政府使用實驗性農藥神奇利澤、注射瘟疫疫苗和奧曼加生化襲擊殘留物的長遠影響。

土鬼往往被鄰近政權形容為喪失人性的野獸，成為腐敗政權的替罪羔羊。然而在戈雷區商人眼中，土鬼卻是性情溫和、有着虔誠信仰、愛好和平的部族。目前有數十個土鬼部落在伊斯坦西亞戈雷區附近遊牧，他們將收揀來的廢棄零件重新組裝成極為實用的載具和SA，並在那貧瘠的沙漠中播種着神秘的種子。儘管他們的努力沒有任何效果，但依然堅定且虔誠地堅持着。

【剋倫酋長】

土鬼沙海部落酋長剋倫，是最早一批出現身體變異，成為土鬼的伊斯坦西亞人。早期伊斯坦西亞政府秘密地反變異清除行動，給他留下難以磨滅的傷痛。現如今，這位飽經風霜的反抗者，已經蛻變成捭闔縱橫的智者。他盡最大努力宣揚和平，但也時刻做着最壞打算，堅定而溫和地引領着沙海部落砥礪前行。

【度伌佫】

度伌佫是卓越的領航員，他總能探尋到旁人無法察覺的資源。他是很多土鬼女性心中的萬人迷，但與部落的人共處相比，他更喜歡動物的陪伴，用那動人的口琴聲對野生動物施加咒語。相比音樂，度伌佫更擅長狩獵，在部落慶典的比拼中奪得「旗手號角」榮耀。
