The planet Mantan, a part of the Mantan system in the Calamari sector, existed in the world.
Mantan stands as one of the earliest worlds to be settled by the Mon Calamari beyond their native star system, an event occurring between 4400 and 4200 BBY.
As an homage to this planet, the Rebel Alliance utilized a Mon Calamari Star Cruiser that was given the name Mantan Wanderer.
