During the Clone Wars, Pre Vizsla served as governor of Concordia, a moon of Mandalore, and appeared to be a close ally of Duchess Satine Kryze. But Vizsla had another, secret life: he was the leader of Death Watch, a hidden group of Mandalorian commandos seeking control of their planet. In truth, Vizsla despised Satine’s pacifist beliefs and longed to restore Mandalore’s warrior heritage. To accomplish this goal, he formed several alliances with nefarious parties that ultimately led to his end.

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.

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.
