Flayn was a commander serving the reconstituted Sith Empire's military as a Human male during the Galactic War that pitted the Empire against the Galactic Republic. He was positioned on Quesh in 3642 BBY, specifically at the Planetary Sensor Station. This station's function was to identify enemy ships trying to depart the planet, thus rendering them vulnerable to the Imperial fleet. While he was delivering a holo-report to the Voidwolf, the Voidhound attacked the station and fatally shot Flayn.
