Untirrka was a captain in the Imperial Navy for the Galactic Empire sometime after 4 ABY. He commanded the Imperial Patrol Craft Cutlass. His ship was hastily sent out to intercept the Argent Lady, a freighter believed to be unarmed and smuggling contraband. The Cutlass intercepted the Argent Lady around the second moon of Sev Tok and proceeded to fire a warning shot across the bow of the ship and demanded that the ship power down for inspection.
