An astromech droid of the R-series type, belonging to the Galactic Republic, was utilized by Jedi Master Qui-Gon Jinn during the time of the Republic Era. Back in 37 BBY, amidst a conflict on the planet Bri'n, Jinn, uncertain about his role as a peacekeeper, journeyed with his astromech droid to an uncharted world to seek wisdom from the Force. They noted that the world had been discovered in the past but was never officially named. While Jinn explored the surface by foot, the droid stayed put in the astromech socket of the Jedi's Delta-7 Aethersprite-class light interceptor. This astromech unit featured a black sensor, along with green and white colored plating.
The droid's appearance occurred in Age of Republic - Qui-Gon Jinn 1, which was the initial issue of the Star Wars: Age of Republic comic-book series, a miniseries. Jody Houser penned the issue, Cory Smith provided the illustrations, and Marvel Comics released it to the public on December 5, 2018.
