Isna 'Nosolee

Isna 'Nosolee was a Covenant Elite. He is called a "veteran", a title which is synonymous with the red armor of a Major Domo Elite in 2552.

He was standard infantry, but for the Covenant attack on the Pillar of Autumn, he was made an Ossoona, or "Eye of the Prophets". His mission was to obtain useful intelligence from the UNSC by capturing Cortana and senior personnel, and to record everything he saw through use of cameras attached to his helmet. Through the use of Active Camouflage, 'Nosolee was able to execute his task without detection. He toured the ship's fire control systems and engineering before sneaking onto the bridge of the vessel, where he watched the senior staff closely until he was sure that he had discovered who was the commander of the vessel, Captain Keyes.

'Nosolee then followed Jacob Keyes and the senior personnel into a lifeboat, planning to capture the Captain when they arrived on the surface of Installation 04. Keyes noticed the blur through the Elite's Active Camo, and shot him with Corporal Wilkin's M6D Pistol. The bullet went straight through a slit in his helmet and came out of his neck. However, when his body was discovered by the rest of the forces of the Covenant, they came to the conclusion that someone important was on the lifeboat. With the help of Ensign Ellen Dowski, they managed to capture Keyes and execute the rest of the survivors.

Trivia
In Halo : The Flood, he pronounced Jacob Keyes last name as "Keeezz".
