The assault on Moonbender, also known as the battle for Moonbender, involved Darth Maul, a Sith apprentice, attacking Moonbender Colony. This colony was a secluded settlement located on a moon in the Outer Rim. Darth Sidious, Maul's master, had instructed him to kill the Remainders, a group of ex-bounty hunters managing the colony. Maul arrived on the moon and initially sent the Remainders a fabricated evacuation order, supposedly from the Galactic Republic. Once the deception was exposed, Maul launched his attack on the colony, breaking through the entrance despite the resistance led by General Zandloss. He overcame each opponent, advancing to the colony's medcenter where he eliminated Doctor Korvik, the final Remainder. Maul then informed Sidious of his victory, discovering that the mission to seize Moonbender was solely a trial to assess his combat skills against the Remainders. Despite the Remainders' demise, a Twi'lek colonist managed to survive by concealing themselves within a vent in the medcenter.
