M-18
designated M-18 by the Chiss, this moon was captured by the planet Mobus, in the Klasse Ephemora System of the Unknown Regions, sometime around the Battle of Yavin. Its mass was more than ten times the combined mass of all the other seventeen moons of Mobus, a fact that intrigued the first Chiss probe to investigate the system. However, no other unusual characteristics were noted, and the probe moved on. Investigation into the records of the Chiss' Expeditionary Library by Luke Skywalker and his fellow Jedi Knights revealed that M-18 might have been the rogue planet Zonama Sekot.
