Gugees are gentle mutant camelids whose name derives from the sounds they make. Like the Soil Ghosts, they arose after the destruction and desertification of Estancia. Wild gugees are proficient in locating water sources, hence nomadic Soil Ghosts often chart their courses after their tracks. Many tribes also domesticate gugees for agriculture and transportation.

Gugee wool is soft and oily, protecting them from hot temperatures and dehydration. Soil Ghosts trim gugee wool to weave into coats, which young adults wear at coming-of-age ceremonies. After gugees pass away, Soil Ghosts will turn their bodies into various crafts. Gugee horns, when grinded into powder and consumed, produce strong medicinal reactions, and can enhance the effects of other drugs. In tribes with scarce medical resources, gugee horn powder will not be sold to outsiders, but retained for local medical use. Wine made from gugee blood is also a prized health supplement, enjoyed only during the sacrificial month.

Gugee products are popular throughout the world and abundant in Gray Zone black markets. This attracts many poachers to the desert, and some well-equipped poachers even raid Soil Ghost villages. Soil Ghosts execute poachers whenever they catch them, and scatter their bodies to the edge of the desert as a warning to others.

咕嘰是一種性格溫馴的變異駱駝，它的名字源於它發出的聲音。像土鬼一樣，它們在伊斯坦西亞滅亡和沙漠化後出現。野生咕嘰擅長尋找水源，土鬼會追蹤它們的足跡來規劃路線。許多部落也會馴養咕嘰用於農業生產和運輸。

咕嘰的毛輕盈柔韌帶有油脂，有着極佳的隔熱防水效果。每年祭祀月的時候，會修剪咕嘰身上過長的毛，收集起來製成外衣，當作禮物給孩子們在成年禮上穿着。咕嘰死後，土鬼也會利用起來製成各種用品：咕嘰犄角製成的粉末如果單獨使用，會有極強的致幻效果。但以不同比例與其他藥物調配使用，反而有增強藥效的作用。在醫藥資源稀缺的部落，土鬼不會將犄角粉末出售，而會視為珍貴的秘藥；咕嘰血製成的酒是上佳補品，只有在祭祀月的時候才能任意享用。
