Ado 'Mortumee

Ado 'Mortum, an Elite, was a spy for the Covenant High Council of Masters. He wore the blue armor of a Minor Domo Elite.

He was sent to observe the capture of Captain Keyes as the human and his Bumblebee lifepod crew mates attempted to escape from the pursuing Covenant. He watched from his Banshee as Keyes was captured and the rest of the survivors killed by a group of Elites that had dropped from a Spirit.

Later he was sent to spy on Field Master Noga 'Putum as the field master commanded an ambush of a human caravan led by First Lieutenant Melissa McKay. One of the Marines in the convoy, Lance Corporal "Snaky" Jones, a sniper, spotted and shot him with a Sniper Rifle as he stood next to the Field Master. The bullet went up and out the spy's head, causing it to violently explode.
