Clone Wars Era
Trilla Suduri was once a Jedi Padawan to Jedi Knight Cere Junda during the Clone Wars. When Supreme Chancellor Palpatine revealed himself as the Dark Lord of the Sith and issued Order 66 the clone armies of the republic turned on their Jedi Generals & Commanders and proceeded to execute them all per their mandate. Cera & Trilla managed to save a group of younglings from the purge but they were soon discovered by Imperial Troopers. Cera tried to lead the Imperials away much to Trilla's objections. Cera and Trilla were captured and Cera witnessed Trilla's fate as she was turned into an inquisitor before her eyes. The event caused Cera to tap into the Darkside of the force, an act that traumatized the Jedi Knight and forced her to cut herself off from the force.
Redemption & Death
Trilla would face Cal Kestis one final time over the holocron at the Fortress Inquisitorius. The two fought a ferocious duel with Cal striking a powerful blow that destroyed her replacement lightsaber and disabled Trilla. Cere confronted Trilla and managed to reach her former padawan. As Trilla finally let go of her anger she found herself frozen in her tracks unable to move. Fear immediately overcame her as she heard a loud thud followed by a very ominous breathing sound. Cere & Cal watched as Darth Vader stepped forth and made his presence known. He declared that Trilla had failed him and ignited his lightsaber. Trilla's last words to her former master and her arch rival were , "Avenge Us."
Vader then bi-sected the Inquisitor for her failure and treason.
