Uruo 'Losonaee
From Halopedia, the Halo wiki
Uruo 'Losonaee was a Covenant Elite and member of the respected Dn'end Legion. He was also operations officer aboard the Reverance-class cruiser Incorruptible. Of all the bridge officers of the ship, he was the youngest and least experienced.
'Losonaee was aboard the ship when it escaped The Battle of Installation 05, and the Civil War of the Covenant to Joyous Exaltation. He was then at his post when the Incorruptible traveled to Onyx, where he was likely killed in The Battle of Onyx.
