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.
