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.
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.
The elder leader of a town of Ming Po on Carlac, Chieftain Pieter hated the intruding Death Watch and their bullying ways. The marauding gang set up camp next to Pieter's town, and kidnapped many of the defenseless townspeople to toil as their servants. Pieter bravely confronted Vizsla, demanding the return of his people. Vizsla appeared to concede, but it was all a cruel ploy to teach Pieter a painful lesson.
When the nomadic Death Watch army arrived on the peaceful planet of Carlac, they intruded in the towns of the native Ming Po. Under Pre Vizsla's command, the Death Watch kidnapped many defenseless natives, forcing them to serve their needs as they set up a temporary base of operations. Not even Tryla, the grand-daughter of Chieftain Peiter was spared. Tryla befriended Ahsoka Tano, a Jedi hidden in their midst, but did not live long enough to see her town liberated.
Ahsoka Tano, a Togruta female, was the Padawan learner to Anakin Skywalker and a hero of the Clone Wars. Alongside Anakin, she grew from headstrong student into a mature leader. But her destiny laid along a different path than the Jedi.
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.
