The MX inside the weapons depot
Located in Galactic City on Coruscant, this weapons depot served as a storage facility for new, untested weaponry, situated not far from the primary command hub of the Republic.
During the time of the Great Sith War, when the Krath's invasion of Coruscant occurred, Mandalore the Indomitable along with his Mandalorian Crusaders took control of the depot for a short period. During that time, they were successful in their mission to abscond with the experimental weapon known as the MX.
