Zaret was a male human who operated as an informant for the Nihil pirates located on the world of Banchii. Posing as a farmer, Zaret assisted the colonist Kooba in transporting a shipment of Drengir seeds onto Banchii, an action that led to Kooba's demise and a raid on the local Jedi temple. Following the assault, the Jedi who were based at the temple came to the conclusion that Kooba had received assistance, though they remained ignorant of Zaret's real loyalty. Upon discovering that the Jedi were investigating, Zaret reached out to his Nihil contacts and proposed that they needed to intensify their activities on Banchii.
Zaret's initial appearance was in Star Wars: The High Republic: The Edge of Balance, the first volume of the manga series. Justina Ireland and Shima Shinya wrote it, Mizuki Sakakibara provided the illustrations, and Viz Media released it on September 7, 2021.
