A female person was part of the Junk Mavens, a group that made their home on the junk moon known as Quantxi during the High Republic Era. This Junk Maven, alongside a fellow member, encountered members of the Nihil pirate group on Quantxi, including their leader, Marchion Ro. Although the Nihil's goal was to ensnare the Jedi Order in a trap, the Junk Maven's colleague created a diversion, allowing her to flee toward a communications facility. Despite being chased by the young Nihil recruit Krix Kamerat, the Junk Maven succeeded in reaching the tower and transmitting a call for help that was received by the Jedi.
During the period of the High Republic Era, this individual was a member of the Junk Mavens, a group living on Quantxi, the Junk Moon orbiting the planet Ord Mantell. At that time, a group of pirates belonging to the Nihil organization established a presence on Quantxi as part of a scheme to lure the Jedi Order into an ambush. These pirates, including the Nihil leader, Marchion Ro, planned to send a distracting force into a battle against the Jedi. As this force departed, the Junk Maven and a partner approached Ro and several other Nihil members, including Zagyar and the young recruit Krix Kamerat, on Quantxi.
While her partner caused a distraction for the Nihil, claiming to want no involvement in their galaxy-wide conflict, the Junk Maven made her escape, heading towards a nearby communications center. Ro dispatched Kamerat to pursue the Junk Maven, and the boy chased after her with Ro's weapon, demanding she stop and threatening to shoot. The Junk Maven dodged Kamerat's shot and managed to evade him, but Kamerat eventually caught up, tackling her to the ground.
Kamerat bound the Junk Maven's extremities with restraints, ordering her to stay put. While Kamerat recorded a message for Zeen Mrala, a friend under the care of the Jedi—another element of Ro's plan—the Junk Maven escaped once more. Kamerat gave chase after noticing her disappearance, firing at her when she refused to stop. The shot struck the Junk Maven's hands, but she continued running, eventually reaching the inside of the communications tower. The Junk Maven went to a console and activated a button, sending out a signal for assistance that was relayed to the Ord Mantell Republic base. An enraged Kamerat followed the Junk Maven inside, aiming his weapon, but he was too late; the distress signal alerted the Jedi in the system, who changed course for Quantxi and requested backup.
The Junk Maven, a female member of an avian-like race with clawed feet and a bill, possessed long dark gray hair strands and similarly colored skin. She showed great resolve in reaching the communications tower and sending a distress signal, even after being chased and shot by Kamerat. The Junk Maven emitted various noises while Kamerat was pursuing her.
The Junk Maven was dressed in tattered brown apparel, including a hooded robe and pants. She also wore dark eye protection and carried a pack on her back. To navigate the junk-filled terrain of Quantxi, the Junk Maven used a long stick as a walking aid.
The Junk Maven made an appearance, though unnamed, in the comic book The High Republic Adventures (2021) 4, written by Daniel José Older, with illustrations by Harvey Tolibao, and published by IDW Publishing on May 5, 2021.
