Mesula was an ice moon located in the Mid Rim Territories. Many eons before around 11 BBY, Mesula underwent a cataclysmic rupture, causing it to shatter. The rupture of Mesula resulted in the Mesulan Remnants Belt, a field of ice asteroids that the Pau'an gangster Fyzen Gor would later use to hide the Phylanx Redux Transmitter, a device that Gor hoped to use to initiate a droid revolution across the galaxy.
Mesula was first mentioned in Last Shot, a 2018 canon novel written by Daniel José Older.
