【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.

【Nazar】

Nazar is Koren’s chief advisor and head of the Endizars, the four “Spiritual Pillars” of the Sahai tribe. A calculating tactician and cunning warrior, Nazar is responsible for creating many formidable Soil Ghost battle formations and strategies. Only a handful of Soil Ghosts are old enough to remember that before Estancia’s fall and his own mutation, Nazar was once a mutant-hunting officer of the Estancian army.

【Golgo】

A rare newborn from the heavily mutated Corabas tribe, Golgo’s parents entrusted him to Chief Koren’s care to spare him from the Corabas’ extremist leaders. Showing great interest in technology and gadgets, he mastered his superhuman left arm under Nazar’s mentorship and became a skilled metalsmith. Though a ferocious giant on the battlefield, Golgo is actually a gentle soul who humors the many children hanging around his forge.

【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。

【納薩爾】

納薩爾是安迪薩爾之首，也是剋倫酋長的首席顧問，沙海部落四大「靈柱」之一。他是足智多謀的戰術大師，也是狡詐多變的戰士，他制定了許多令敵人膽寒的土鬼戰鬥編隊和戰術。只有極少數土鬼老人知道，在伊斯坦西亞倒台和納薩爾出現變異之前，他曾經是伊斯坦西亞軍中負責抓捕變異者的軍官。

【佝苟】

科拉巴斯部落的土鬼大多是重度變異，而佝苟就是出生在這個部落的罕見新生兒。他的父母把他託付給剋倫酋長照顧，以避免受到部落極端領袖傷害。佝苟從小對科技和小器具表現出極為濃厚的興趣，在納薩爾的悉心栽培下，他能夠將擁有怪力的左臂發揮到極致，並成為了技藝超群的鐵匠。雖然在戰場上佝苟是兇猛的巨人，但實際上他有着的溫柔靈魂，孩子們會在他的工作間嬉戲打鬧。
