Justa, a frigid and stone-covered satellite, orbited the planet Mutanda and functioned as a crucial hub for the interstellar prothium trade. This moon, referenced in moon lore, and its parent planet Mutanda, was the sole location of a starport within the Killaniri system. During the Galactic Civil War, the Empire maintained a garrison there, ostensibly to safeguard the interests of entities like the BlasTech Corporation, Blethern Gas Industries, and Czerka Arms across the galaxy's trade routes of prothium.
