Orlin

"All squads report to the mess hall."

- Orlin

Orlin was a UNSC AI designed to run Corbulo Academy of Military Science. She was in service during the Battle of Circinius IV.

Corbulo Academy of Military Science
"Hastati Squad leader on the field. Exercise paused."

Orlin was the Academy's AI for an unknown period of time before it was destroyed. During this time, she would announce events from the timetable such as meals using a campus wide speaker system. She also performed tasks such as telling the recruits when training exercises have finished and turning the lights on and off at the request of high ranking cadets in certain situations.

Battle of Cirinius IV
"All cadets, report to the tether! A campus-wide evacuation has been ordered."

At the beginning of the attack on Corbulo Academy of Military Science, she announced the campus-wide evacuation, on a loop. However, when Cadet Lasky awoke from unconciousness shortly after, she had ceased, likely due to the lack of power. It is assumed that she was destroyed when the Covenant glassed the planet.

Trivia

 * It is likely that Orlin is a Dumb AI because she tends to use the same set phrases and does not vary her tone of voice.
 * She is one of the few UNSC AIs to not have a mentioned hologram, however, she probably still possesses one.
