He was also an Operations officer aboard the Reverence-class cruiser Incorruptible. Of all the bridge officers of the ship, he was the youngest and the least experienced. As he was newly initiated in combat, he carried the rank of a Elite Minor.
'Losonaee was aboard the ship when it escaped the Battle of Installation 05, and the Civil War of the Covenant to Joyous Exultation. He was then at his post when the Incorruptible traveled to Onyx, where he was likely killed in The Battle of Onyx.
