The EF76 Nebulon-B escort frigate Xerxes served in the Rebel Alliance Navy at the Battle of Mylok IV during the Galactic Civil War. Imperial forces, led by Grand Admiral Demetrius Zaarin, destroyed Frigate Xerxes as Rebel leaders attempted to receive new hyperdrive technology from dissident Nharwaak researchers. Following the destruction of the Xerxes, Imperial forces routed the Nharwaak, who had betrayed their former comrades, the Habeen.
