Ankala Sahm, a human individual, spearheaded the Revengers, a team dedicated to resisting the Crimson Dawn criminal organization. After Crimson Dawn annihilated her village, she allied herself with S'ira and Tanka, both of whom had endured similar tragedies, tracking Crimson Dawn agents and launching attacks against them. On Calior, Ankala and the Revengers received assistance from the subordinates of Sith Lord Darth Vader, who shared their objective of eradicating Crimson Dawn, leading to the group being recruited to aid Vader in his mission.
