Trilla was born to a family of little consequence, however at a young age she was discovered to have an extraordinary ability her people call Skywalkers, able to navigate the Chaos of space that surrounds the Chiss ascendency, she served the fleet valiantly until the age of 14 common among her people, when she retired she was given the option to join many of the families but instead made her way out of the Chaos and into the greater galaxy for her the unknown was something to be seen. travelling until she finally met one Tyranus who offered her a prestigious position leading an army of battle droids, a position that she held with distinction, for it would bring her to the furthest ends of the Galaxy aboard fine ships of war that the Ascendancy would only be able to dream of.
As the war dragged on she became well known among her allies and enemies alike, spending most of her time on remote planets in the outer rim, what most wouldn't expect from a member of the CIS command structure was that she had compassion for those she 'subjugated' Trilla never fully agreed with the way that the CIS conducted themselves and did whatever she could to lead her droids as she sought fit. To the point that some worlds actually would feel safer under her leadership than even some Republic worlds. Close to the end of the war Trilla intercepted a communication to the Republic forces, one that contained Order 66, from that moment on the Galaxy changed, her battle droids in an instant all shut down leaving her stranded aboard her command ship as it's sole living member. She managed to limp the ship back to CIS space, but by that time the Galaxy was a very different place. And now, it was up to her to find her way in the new world order.
Trilla soon after making it back to the CIS space would find that there was already a republic cruiser in orbit, with no battledroids under her command, and no way to defend herself she soon found herself taken prisoner, and sent to an internment camp, it wasn't until another Chiss by the name of Thrawn had realized that one of his own was in Imperial internment that he requested to meet her, finding that they fought on opposite sides of the war he found very interesting. The two spoke for quite some time about the tactics that they used to defeat their enemy. Though they never met in combat during the conflict he admired her skill as a commander. releasing her from prison and giving her command of a small fleet of ships stationing her out into the outer rim. Trilla would soon to grow quite fond of the Admiral as more of his victories would become known. Should she get the chance to meet him again, she would be sure to show him the proper respect he deserves.
Never making it back to CIS space Trilla's ship was boarded by Trandoshan slavers, when the found her, she put up as good a fight that she could slaying fourteen before finally being subdued. Her body was violated and her neck soon found a collar around it. Being brought to the Zygerrians who quickly realized the prize that they held would soon send her to a training camp to learn that she no longer was a leader of the CIS, but destined to serve whomever would purchase her for an exorbitant amount at an auction, her defiance had led her to many nights in confinement or worse, to be passed around the taskmasters until she finally 'respected' their wishes only doing so for the torment to stop.
