Bolvan was a Human captain of the Imperial Navy during the Imperial Period. He captained the Imperial Star Destroyer Devastator under the command of the Dark Lord Darth Vader. In 7 BBY, when an Imperial-produced bacterial plague began to spread out of control on Falleen, Bolvan suggested the sterilization of the planet, but Vader ordered an orbital bombardment of the world instead. Later, in 0 BBY, while serving as gunnery captain, Bolvan participated in the Devastator’s capture of the Rebel CR90 corvette Tantive IV, during which Chief Gunnery Officer Hija spotted an escape pod fleeing from the impounded Rebel vessel. However, Bolvan ordered him not to fire on the pod because the Devastator’s gunnery sensors detected no lifeforms aboard.
