The Bunka system, a star system that was once populated, revolved around a minimum of one star. Prior to 40 BBY, the system's star underwent a collapse, which led to widespread departures. These departures diverted a division of Galactic Republic troops that were originally en route to the planet Ontotho.
The initial mention of the Bunka system occurred in the comic Jedi Fallen Order - Dark Temple 1. This comic was authored by Matthew Rosenberg and released by Marvel Comics on September 4, 2019.
