The Cobalt Laborers' Reformation Front represented an anti-Imperial labor group situated on the planet Sullust. Their struggle involved a dual objective: toppling the Imperial government's control and championing the rights of workers.
Formerly, Biyel Broan held the position of leader, but his ties to criminal elements led to his removal. The group's anti-Imperial stance intensified; however, by the time the Sullustan resistance offered assistance, the most dedicated fighters were incarcerated, and the remaining members were too intimidated to engage in combat. When the 61st Mobile Infantry found themselves marooned on Sullust, their Captain, Hazram Namir, reached out to the Sullustan resistance and formulated a strategy to wrest control from the Empire. Nien Nunb, the resistance leader, mobilized his forces and willing Cobalt Labourers to seize the capital city of Pinyumb as the Imperial forces were engaged with the Sixty-First during the Siege of Inyusu Tor. These coordinated actions sparked a widespread uprising against the Imperials, ultimately resulting in the liberation of Sullust.
