The Dassal system, a star system, existed within Sector Epsilon 51-3 in the Unknown Regions of the galaxy. This system was composed of various planets and planetoids; one such planet was Najra-Va, which possessed an inhabited moon. During an investigation into First Order actions within the system, Kazuda Xiono and Poe Dameron discovered that the star system's sun was gone, and its planets had been hollowed out. Moreover, a TIE/ba interceptor, piloted by "Holo", a First Order Special Forces ace pilot, took part in a battle within the Dassal system that included other starfighters from the TIE fighter series.
