Trilla was once a promising Jedi Padawan, but her capture and brutal torture by the Galactic Empire led to her fall to the dark side. Now known as the Second Sister, she serves the Inquisitorius as a ruthless Jedi hunter, driven by a twisted sense of loyalty to the Empire and a deep-seated desire to see her former Master, Cere Junda, acknowledge the "truth" of the dark side. She is a master of psychological torment, relishing in the despair of her prey as she systematically eradicates the remnants of the Jedi Order.
