The Bane Brigade functioned as a military division of the reconstituted Sith Empire during the Great Galactic War. Khun Tazith established this unit, and he was known for his dedication to the soldiers within the brigade as they fought against the Galactic Republic. Tazith also planned their missions, turning the unit into an elite force within the Imperial Military, with Sith commanders leading them into combat.
Their accomplishments included the destruction of a Jedi Enclave located on Genarius and igniting the seas of Iskalon. Due to these actions, the Republic labeled the Bane Brigade as ruthless butchers and war criminals. During their campaigns, members of the Bane Brigade received cybernetic replacements for lost limbs, with Tazith present during these procedures. In one particular mission, the brigade was sent to Rhen Var, where they attacked a Jedi encampment and massacred everyone there. However, the unit remained at the site for too long, allowing the Republic Military to retaliate with an aerial bombardment that annihilated the entire Bane Brigade, resulting in their defeat. The Gran named Shodarra, who served in the Republic forces, witnessed the Bane Brigade's destruction and believed that no one could have survived the attack. Tazith reportedly mourned the deaths of his soldiers, even though the men and women of the unit were considered heroes by the Sith Empire.
During the Cold War, the Sith launched an assault to feign an attempt to capture the planet Hoth. This prompted the Republic to deploy forces to counter the Empire and maintain control of the planet. However, the Sith Empire's true intention was to drain the Galactic Republic's resources by making them defend a strategically unimportant planet. To further this objective, Special Advisor to the Minister of War Khun Tazith initiated a clandestine project with the help of an Imperial spacer to create the illusion that the Bane Brigade was still active on Hoth. The operation was so convincing that Captain Graich of the Imperial military began to believe that the Brigade was still alive and would crush the Republic Army on Hoth.
Tazith's ultimate goal was to lure the Republic's elite forces, who would have been redeployed to combat the supposed Bane Brigade. These enemy forces were meant to engage the phantom Brigade's operations in Clabburn Tundra, but in reality, they were expendable cannon fodder. Once the Republic forces arrived, they would be eliminated when the Clabburn was collapsed upon them. The brutal strikes carried out by the Imperial spacer successfully garnered the enemy's attention and reinforced their belief in the Bane Brigade's continued existence, causing morale within the Republic forces to plummet. An intercepted Republic holocall revealed that General Uchang reported that the Bane Brigade was still operational, although General Shodarra doubted this, recalling their destruction years prior. General Krepkit urged his comrades to investigate the claims, as the Brigade had destroyed his people's capital in the past.
Consequently, the operation achieved its objectives, and the Empire determined that the Republic Special Forces Division and members of the Jedi Order were dispatched as part of the Galactic Republic's elite response. Therefore, Tazith prepared for their arrival and the trap he had set for them at Clabburn Tundra. With the spacer's mission accomplished, Special Advisor Tazith congratulated them and declared that the legend of the Bane Brigade would endure through their efforts.
