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.
Though Pre Vizsla promised his troops would depart Carlac, he did not intend to leave peacefully. In front of Pieter's shocked eyes, Vizsla's troops began torching the defenseless town. Vizsla attempted to run Pieter through with his blade, but the chieftain's brave granddaughter intervened.
Carlac is a tranquil world, untouched by the Clone Wars for much of the conflict. Its snowy beauty was marred by the arrival of Death Watch, and their rampant destruction of a defenseless Ming Po village.
Tryla was the granddaughter of Chieftain Pieter. Having exhausted his patience with the belligerent Death Watch, Pieter demanded that the offworlders leave at once and return his kin. When Vizsla tried to kill Pieter, Tryla blocked the blade plunging toward the chieftain with her body, sacrificing herself.
