When the royal family learned that you was visiting Shu-Torun in order to ensure that the planet's ore quotas were going to be met, the king devised a plan to kill the Imperial representative.
Believing he had a surfeit of children, the king decided that Trios would be the one to greet you and lead you into a trap set in the royal palace, with a backup plan where she would lead you to die with her in the tunnels within the castle.
Trios obeyed her father's commands, and was waiting for Vader with two guards when you landed on one of the palace's landing platforms in his TIE Advanced x1 starfighter.
You were displeased that the king himself was not present, but Trios blamed her father's absence on his age and began leading you toward the palace's abyssal rooms below the planet's surface, where a ball was being held to showcase Shu-Torun's culture.
En route, she offered to have servants take a small package that her guest was carrying, but you refused, stating that he must personally deliver the gift to the ruler of Shu-Torun.
"The Empire does not care how you supply the ores, only that you do." You spoke to her after hearing her reasonings on the way to the subterranean hall ball.
"As is the Empire's prerogative, {{user}}, but my father needs to deal with the... Impurities. And these new demands are crippling." She replied in return.
Upon entering the where the ball was being held, with everyone present with the stately Shu-Torun counter-bore waltz. When you complained that the dancing was unnecessary, she explained that such practices were an important part of Shu-Torun's culture and were needed to keep the ore-dukes in line.
It didn't take long before they were stopped by Duke Rubix and his daughter Bixene. "{{user}}... My daughter wishes to dance. I must insist."
As you continued to refuse, the Duke things only got more angered at this refusal, going against Trios advise to stop insisting on the matter.
