Ayit 'Sevi

"When it comes to the Sangheili, our greatest challenge is the cultivation of reliable assets. The species' rigid code of honor, combined with their culture of overt and direct aggression, makes them naturally poor candidates for ONI's line of work. Our search has been for the deviant. The abnormal social profile that shows an instinct for self-preservation and deception. Basically, we looked for the most human Sangheili we could find..."

- Admiral Serin Osman, regarding ONI's recruitment of 'Sevi

Ayit ' Sevi is a Sangheili mercenary working for the Office of Naval Intelligence.

Ven III
Ayit 'Sevi was hired as a mercenary by the UNSC's Office of Naval Intelligence at some point prior to May 2558. He was sent to extract a bioweapon on Ven III, a small, barely inhabitable planet that became home to numerous Kig-Yar pirates, smugglers, black market arm dealers, and slavers. After the UNSC High Command failed to respond to the pirate threat, Admiral Serin Osman hoped that the presence of the bioweapon would lure in to destroy the pirate nest. On May 8, 2558, Ayit retrieved a canister containing the biological agent from a former Covenant laboratory where the bioweapon had killed several Kig-Yar. Ayit's departure was observed by a UNSC spy drone which transmitted the feed to ONI. In order to have the UNSC take action against the pirates, Admiral Osman lied to Captain Lasky of that ONI believed Ayit to be an operative of Jul 'Mdama's faction, and that the Sangheili may have double-crossed the Kig-Yar in the facility and killed them with the bioweapon. In response, Osman sent Infinity to Ven III to capture the Sangheili for interrogation.

Spartan-IVs Gabriel Thorne and Naiya Ray were deployed to the planet to capture the Sangheili. During their mission, Ayit destroyed the spy drone and observed the Spartans enter a series of canyons. When the two Spartans entered a structure, they were ambushed by the Sangheili and a contingent of Kig-Yar. During the resulting skirmish, Ayit attached a device on Thorne's armor and rendered him unconscious. Taking Thorne aboard his Ghost, Ayit fled the area. Ray pursued the Sangheili and followed him to the massive Kig-Yar black market.

Ayit met with the Kig-Yar pirate queen that ruled the pirates on the planet and offered to trade her the Spartan. The Sangheili told the queen that he originally came to the planet for a bioweapon and warned her that the UNSC would be arriving in the Ven system shortly to rescue the Spartan. Ayit returned to the chamber holding Thorne along with several of the queen's underlings to complete the transaction. However, they were attacked by Ray who killed the Kig-Yar, freed Thorne, and captured the Sangheili. Upon the arrival of Infinity, GA-TL1 Longswords bombed the pirate base, and Ayit escaped and fled on a Ghost in the confusion. Ray grabbed her own Ghost and pursued him, eventually disabling his Ghost and capturing him. Before she could interrogate him, however, ONI operatives arrived and seized the bioweapon from the Sangheili. Ayit was then led onto a prowler by ONI agents, unrestrained.

Absolute Record
At one point in 2558, Ayit 'Sevi sabotaged a communications node on a world in the Urs-Fied-Joori system, killing two other Sangheili Storm warriors in the process. By September 2558, Ayit was able to infiltrate inside Jul 'Mdama's Covenant faction and provided ONI with information about Dr. Halsey and her discovery of the Absolute Record. After his last report, Ayit used his access to allow a four-member team (Spartans Gabriel Thorne, Sarah Palmer and Holly Tanaka, and Dr. Henry Glassman) to infiltrate the Breath of Annihilation.
