Lev Kepzen held the rank of captain within the Galactic Empire's ranks, commanding the EF76 Nebulon-B escort frigate named Feral. His service took place circa 0 ABY. In that year, Kepzen, in command of an Imperial Naval taskforce that included the Feral, successfully captured the Solar Terrors—a group of pirates—following a pursuit lasting three months. The pirate group's leader, Venslas Beeli, capitulated at their base when he recognized the overwhelming odds.
Timothy S. O'Brien referenced Lev Kepzen in The Far Orbit Project, published in 1998. This publication served as an addition to Star Wars: The Roleplaying Game created by West End Games.
