The warrior clans of Mandalore were believed to have been wiped out ages ago, their tattered remnants exiled to the Concordia moon. But as the Clone Wars swept the galaxy, the treacherous governor Pre Vizsla resurrected the Mandalorians, and with them, their legendary combat armor that was feared across the galaxy. Backed by Count Dooku and the Separatists, Vizsla began building an army to retake Mandalore from the control of pacifists who were trying to bury violent Mandalore's past. As the coup became inopportune, Dooku abandoned the Death Watch, leading once again to their exile. The Death Watch became a murderous band of nomadic outlaws, battle-worn rogues that wandered the Clone Wars.
Pre Vizsla publicly served Duchess Satine as the governor of Mandalore's moon Concordia, but was really the leader of the Death Watch, a secret society of Mandalorian commandos who sought to overthrow Satine's government and reclaim the Mandalorians' honor as warriors. Vizsla and Count Dooku plotted to assassinate Satine, which would lead to a Republic occupation of Mandalore. Vizsla's Death Watch would then liberate the planet, joining the Separatist cause. Things did not go according to plan, and Vizsla and Dooku bitterly parted ways. Death Watch became a group of nomadic warriors, with the formerly manicured and orderly Vizsla becoming unkempt and battle-worn as their leader.
A fierce warrior concealed in sleek Mandalorian armor, Bo-Katan was the ever-loyal lieutenant to Pre Vizsla, and a proud member of the Death Watch splinter group. Bo-Katan rallied to Death Watch's call for Mandalorians to embrace their martial heritage and find glory in war. She was confident, sardonic, and deadly.
A deadly, agile Sith Lord trained by the evil Darth Sidious, Darth Maul was a formidable warrior and scheming mastermind. He wielded an intimidating double-bladed lightsaber and fought with a menacing ferocity. Though he fell in battle against Obi-Wan Kenobi, the Zabrak from Dathomir would prove to be much harder to destroy than originally believed.
Savage Opress was once a common Nightbrother whose fighting prowess impressed Asajj Ventress. Transformed into a monstrous warrior by Mother Talzin, Opress became Count Dooku's new assassin and secret Sith apprentice. His loyalty, however, remained to Talzin. The Nightsisters leader gave Savage a new quest: to find his brother, Darth Maul, who had somehow survived his apparent death and was living in exile in the Outer Rim.
