This sector was conquered by the Mandalorians during the time of the Galactic Republic. It was devastated by the Republic and Jedi Order circa 730 BBY.[1] After the formation of the Empire the sector was under the control of Grand AdmiralMiltin Takel. When the sector began having problems with "albino-skinned marauders," Grand Admiral Josef Grunger aided Takel's first officer in patrolling the sector while Takel was away at the secondDeath Star. When word reached Grunger that the Death Star had been destroyed, he immediately opened fire on the officer's ship, disabling it. He soon had control of the sector, which Takel, who survived the Death Star's destruction, was unable to regain.
"The first outline of the Atlas called for a map of the Mandalore sector with an accompanying "Closer Look," but with so many Mandalorian tales being told, we scrapped that for fear of creating contradictions and accidentally tying authors' hands."
