The female relative, specifically the aunt, of Karr Nuq Sin passed away. This death occurred when Nuq Sin was studying on the planet of Merokia. His parents journeyed to his school to inform him of this event. The prior time Tomar and Looway Nuq Sin visited him at school was to discuss his health and potential withdrawal, leading Nuq Sin to initially believe another family member had died, given that his aunt's passing was the previous instance of such a school visit.
The initial reference to Karr Nuq Sin's aunt appeared in the junior novel Force Collector from 2019, authored by Kevin Shinick.
