When Fleet Master Rtas 'Vadum found [[Felix-116 (AAO)|SPARTAN-116]] in space, Autel 'Vadam was assumed to be on board the ''Shadow of Intent'', although he was never seen on board.

Autel was with Thel when the ''Cessation'' arrived at the rebuilt planet Reach. He had hurriedly returned to the Sangheili camp established there to warn the other Elites.

When the Spartans, Cephaus, and a Special Operations unit scouted out Reach's surface, Autel accompanied them. They had come across a group of Covenant Loyalists led by the Brute Chieftain Othreus, and had a massive battle. Autel survived, and aided Thel in the battle against Othreus.

After the death of Oberion the Great, Autel went with Thel and SPARTAN-116 to the downed ''Cessation'' to destroy it, and succeeded in overloading its core. He then returned to the ''Shadow of Intent'' with Thel.

Autel became Special Operations Major and married Cyla 'Cazal at some point between 2556 and 2559, and had 3 offspring. However, they, along with thousands of other newborns, were kidnapped by the Sangheili separatist group, [[The Fallen]]. Thel asked the [[United Nations Space Command (AAO)|UNSC]] to help them track down the leader, and 19 Spartans were sent. When a Vadam elder found out that the Fallen leader, Isto 'Vadum, was headed to Earth, the humans were taken into custody, and forced to run a trial. Autel became greatly resentful of this, stating that they were very distrustful of the UNSC after theyd helped the Sangheili so much, and suffered so much at the hands of the Covenant. He did everything he could to prove that the humans didn't have anything to do with the Fallen, and was successful.

Afterward, Autel accompanied the Spartans and a group of Sangheili back to Earth, launching an assault on Isto's corvette, and found the newborns. He later returned to Sanghelios with them.
