From Halopedia, the Halo wiki
Y'gar 'Pewtrunoee was a Sangheili in the Covenant. He was a member of the respected Dn'end Legion and communications officer aboard the Varric-pattern heavy 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 Shipmaster, 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 Great Schism to Joyous Exultation. He was then at his post when the Incorruptible traveled to Onyx, where he was killed in combat during the Onyx Conflict.
