The oasis mother represented a species of sentient, predatory plant life form. This species was indigenous to the [desert](/article/desert/legends]-dominated world known as Endregaad. These unique organisms made their homes on top of small water sources. Their physical form was characterized by a collection of interwoven vines, which created a trunk-like structure, complete with overhanging branches. Hanging from these branches were sacs, each containing an immature oasis child, the juvenile stage of the plant's life cycle. These oasis children were mobile, possessed a bipedal form, and primarily functioned as hunters, capturing living creatures to sustain their mother. Although sentient, the thought processes of oasis mothers differed greatly from those of other intelligent species; they were entirely amoral, focused solely on their own survival. During the time of the New Republic, a group of oasis children launched an attack on a traveling caravan that was traversing the Endregaad wilderness on its way to the planet's Temple Valley region.
The oasis mother was a self-aware species of plant whose origins lay on the [desert](/article/desert-legends]-laden planet of Endregaad, situated within the Indrexu sector of the Outer Rim Territories. Adult oasis mothers could reach heights of fifteen to twenty meters, resembling massive trees. They established themselves above small water pools, their bodies consisting of a tightly woven network of robust, fibrous vines. This network formed the plant's trunk and extended into the water below. The trunk supported overhanging branches from which hung [gold](/article/color-legends]-hued, fibrous bloodsacks, nearly the size of a small child. These sacks, resembling large fruits, housed immature oasis children, the mobile, juvenile form of the plant, taking the mother a week to cultivate. Emerging from the main body were several shorter, flexible tendrils with sharp tips, used to feed on prey; these vines could strike targets up to four meters away from the trunk. Deep within the oasis mother, beneath the vine-constructed trunk, resided a fungal growth which served as the plant's brain. Oasis mothers exhibited limited mobility, moving very slowly and only at night. They possessed the ability to detect other beings and objects up to fifty meters away, utilizing scent and a keen sense of hearing.

Although omnivorous, oasis mothers were primarily predatory, feeding mainly on wild animals. Oasis children performed the task of hunting living prey for their mother, depositing the bodies into the water pool beneath her. The oasis mother would then envelop each body with vines, and her sharp-tipped tendrils would pierce the corpse, extracting blood and other fluids. The remaining husk was then consumed by the vines and converted into mulch to nourish the mother's growth.
The juvenile "oasis children" were essentially mobile extensions of the mother that bore them. Standing at 1.2 meters tall, these bipedal creatures resembled headless apes. Their bodies were composed of fibrous material, covered in spiky protrusions, and colored to blend seamlessly with the desert environment. They possessed long, powerful arms tipped with poisoned claws, used to incapacitate prey and drag it back to their mother. Oasis children exhibited limited cognitive abilities and were barely intelligent, but they maintained a telepathic connection to their mother, allowing them to receive and understand basic commands. This connection extended up to 25 kilometers; oasis mothers could not communicate with children born to other mothers. Oasis children did not consume food themselves and only lived for a few weeks.

Despite their sentience, oasis mothers possessed vastly different thought patterns compared to other intelligent beings, lacking any form of inherent spoken or written language. The harsh desert conditions of Endregaad, coupled with their isolation from other sentient species, led to their complete amorality. They lacked a sense of right and wrong, focusing solely on their own survival and well-being. Driven by constant hunger, they dispatched their children over great distances in search of sustenance.
Oasis children were nocturnal creatures, completely dedicated to the task of providing food for their mother. They hunted in groups, utilizing their telepathic link to communicate the presence and location of food or potential threats. When prey was detected, they would set up an ambush, typically striking at dawn or dusk. If an oasis mother sensed an impending attack, she would immediately summon all her children back to defend her.
The oasis mothers remained unknown to the other sentient inhabitants of Endregaad, though they occasionally preyed on passing travelers. Folk tales among the Endregaad population spoke of desert-dwelling monsters. In 19 ABY, during the New Republic era, a caravan led by the merchant Simol Toc ventured through the hunting grounds of an oasis mother while en route to the Temple Valley region. They established a camp, and during the night, a group of oasis children seized the guard Rondo and dragged him away to feed him to their mother. The following evening, the oasis children returned and launched another attack on the caravan's guards.
The oasis mothers made their debut in the 2002 Wizards of the Coast roleplaying adventure Tempest Feud, authored by Jeff Grubb and Owen K.C. Stephens. The adventure also included a visual representation of the species, created by the artist Adi Granov. Later, the plants received an entry in the StarWars.com Databank in November 2008, and in that same year, they were included in The Complete Star Wars Encyclopedia.
In Tempest Feud, the player characters assumed the roles of agents traveling to the Temple Valley on a mission, encountering oasis children and an oasis mother along the way. If the players were part of Simol Toc's caravan, they could track the oasis children who abducted Rondo back to the oasis mother. Another group of children would ambush the players when they approached within one kilometer of the mother. Alternatively, if the players were traveling alone, oasis children would attack their camp each night they remained within the children's hunting grounds. The players also had the option to confront and kill the oasis mother controlling the children.
In 2012, Scourge—a novelization of Tempest Feud written by Jeff Grubb—was published. It established the canon series of events for the role-playing adventure, replacing the Tempest Feud player characters with Eddey Be'ray, Reen Irana, and Mander Zuma. However, the novel omitted any mention of the oasis mother or the oasis children, depicting Be'ray, Irana, and Zuma traveling directly to the Temple Valley aboard a skiff, bypassing any camping in the oasis mother's territory. Given the ambiguity of whether the Tempest Feud player characters' encounter with the plants occurred "off-screen" during the events of Scourge, this article assumes that the players' interactions with the oasis children and oasis mother are non-canon.
