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.
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.
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 son of Separatist Senator Mina Bonteri, Lux was young, idealistic, and skeptical of the aims of the Republic and the Jedi Knights. His father was a fervent supporter of the Separatists, and was killed by clone troopers on Aargonar. Lux did not know what to make of Ahsoka Tano and her visit to Separatist space. After a failed peace overture begun by Mina extended to the Republic, Lux's mother died under mysterious circumstances attributed to the Republic. Lux filled her position in the Separatist Senate, representing his home planet of Onderon.
A beautiful, snow-draped world in the Outer Rim Territories, Carlac avoided much of the violence of the Clone Wars. But when the nomadic Death Watch warriors turned it into a camp, the planet and its peaceful Ming Po people faced death and destruction. The cruel Death Watch warriors erected temporary tents next to a Ming Po town, and raided the defenseless village for servants. Chieftain Pieter, leader of the Ming Po, demanded that Death Watch leave Carlac at once, unleashing the cruel temper of Pre Vizsla.
Once a glorious world, the surface of Mandalore has been laid waste by centuries of war. Its people now live peacefully in massive bio-cubes across the planet's golden sand. Under the leadership of Duchess Satine Kryze, Mandalore has turned its back on its violent history. There is still an undercurrent of Mandalore's more martial past, however, and Death Watch has emerged as a painful reminder of Mandalore's warlike ways.
