Y'gar 'Pewtrunoee was an Elite in the Covenant. He was a member of the respected Dn'end Legion and communications officer aboard the Reverence-class cruiser Incorruptible. He was the eldest bridge officer and had been blinded in his left eye during combat. He was the most experienced of the officers aboard the Incorruptible. After Tano 'Inanraree the Ship Master was killed by Voro 'Mantakree, 'Pewtrunoee supported 'Mantakree's promotion to Shipmaster.
'Pewtrunoee 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 killed in combat during The Battle of Onyx.
