Sirai, a Pantoran, held the rank of ensign and worked under the command of Commodore Kyrsta Agate aboard the starship known as the Concord. During the Battle of Jakku which occurred in 5 ABY, Sirai's duties involved managing the ship's weaponry. After the Star Destroyer Punishment inflicted damage upon their vessel, Fleet Admiral Gial Ackbar gave the order for Agate and her personnel to evacuate. As the crew was in the process of leaving the Concord, Agate made the choice to initiate a direct offensive against the Ravager utilizing the full offensive capabilities and armament of her ship.
