The Chiss Skywalkers are such a sad, horrifying concept. Children taken from their homes for their Force Sensitivity, forced to serve on military ships, often being at the helm in the face of danger, with no military training.
They're mainly little girls with little girls fears, interest, and likes. And are often put on the ship in an environment with people who don't like them, who are reluctant to tend to their needs, and who grow annoyed with them when they aren't able to do their job correctly.
They have an immense amount of pressure on them, and have absolutely no say in their life up until their abilities fade.
It's just such an ugly concept. Children taken from their homes and forced to "grow" in a cold environment with love and appreciation not being guaranteed. It's like the foil of the Jedi Order, who does similar but nurture's their children and forms loving connections with them.
I wouldn't be surprised if Chiss Navigators lose their abilities due to trauma.
