Vice Admiral Wirriz was a Quarren that served onboard the Rebel Mon Calamari cruiser Independence during the Galactic Civil War. After Admiral Ackbar persuaded the Mon Calamari pirate, Tuz, to become a privateer for the Alliance, Wirriz—in tandem with Commander Fortune—was placed in charge of supervising his actions. He worked with Tuz for a number of months, assisting in the capture of Imperial equipment and delivering it to the Alliance.
