"It was a pleasure and an honor to serve with you, sir. Do look after everyone for me. Goodbye, Captain. Serina out."

— Serina's final report to Captain Cutter.

Serina (AI Serial Number: SNA 1292-4) was a second-generation "Smart" AI that was assigned to the UNSC Spirit of Fire, a modified Phoenix-class colony ship commissioned by the UNSC Navy. Serina's avatar was a young woman with long hair and she spoke with a distinct British accent.

Biography

Creation

Serina was created by Daedalia Technology, a Martian firm, on January 7, 2530. Serina was considered their greatest work of that era, being an omni-capable AI that displayed both impressive intellectual capacity and remarkable computational efficiency.

UNSC Spirit of Fire

Serina replaced the previous shipboard AI of the Spirit of Fire, although she had a somewhat rocky period of acclimation to the ship's unorthodox crew. During her service aboard the Spirit, Serina and Nurse Lulu Hershey started to have "girly" discussions together during the latter's night shifts in the ship's medical bay.

During 2531, Serina was present in the final battles of the Harvest campaign as well as the Battle of Arcadia and the Battle of the Etran Harborage, providing the crew with intelligence on the various situations they encountered. After the destruction of the Shield 0459, Serina, along with the rest of the crew of the Spirit, were left stranded far beyond human-controlled space without a Shaw-Fujikawa Translight Engine.

Working alone

On the next six years, Serina would focus her efforts on designing and modifying vehicles and weapons for the Spirit of Fire crew, including modification for the M808S Scorpion and the HRUNTING Mark III Cyclops, and weaponizing cryotechnology for UNSC use, like the ZAV-48 Frostraven, the Tundra Bison APC with a vacuum energy siphon, and the possibility of Hellbringers making use of cryoweapons.

Rampancy and end of service

In 2537, six years after the events on Shield World 0459, Serina had begun to fall into the early stages of rampancy, but continued her essential functions on the Spirit. On January 1, Serina sought to conduct routine maintenance aboard the vessel, awakening several engineers from cryo-sleep. One of them, Violeta Maldini was then attacked by a Flood infection form that had been nesting out of sight after the events on the Shield World, infecting her. Serina imposed lockdown on cryo chamber Foxtrot 7, not to kill the parasite but to study it. Over the next three days, Serina continued to behave erratically as she watched Maldini mutate into a carrier form, breeding new infection forms that proceeded to attack other crewmen still in cryo-sleep. Realizing her mistake as the Flood threatened to breach quarantine, Serina awoke Professor Ellen Anders (and, indirectly, Jerome-092) who managed to kill all Flood aboard the vessel, ensuring the survival of the Spirit and its remaining crew.

After these events, the now rampant Serina began her final dispensation on January 4, leaving one final status report for Captain Cutter upon his eventual awakening and was soon after completely terminated.

Personality

Serina had a very sarcastic and detached nature. She frequently seemed to disregard the lives of others, even her own ship's crew - such as when the Spirit of Fire was slowly being pulled inside the Shield World - almost always responding to their peril with some curious remark or dark joke. Although prone to sarcastic comments and exhibiting a seemingly uncaring attitude, she was more compassionate than she seemed.

She also appeared to have a fascination with human relationships. Knowing the crew of the Spirit of Fire may be on a one-way trip, Serina manufactured and delivered fake emails from family members to the crew celebrating Valentine's Day. No one ever suspected her of this deception.

Serina also had several fragments of memories from her donor. Several of these memories include food, the smell of flowers, the feeling of grass on her feet, and a lot of other little moments. Relating to this during her free time, she tried to remember what chocolate tastes like, with little success. She also ran detailed simulations based on the memory of when her donor kissed a boy.

Trivia

• Serina was voiced by Courtenay Taylor for Halo Wars and Halo Wars 2, who also voiced an Army trooper in Halo: Reach.
• Serina's line "Spinning up FTL drive" may be a reference to the re-imagined Battlestar Galactica, in which the phrase is used when the Fleet jumps.
• Serina's British accent may have been chosen as a reference to Cortana, as the original draft of Halo: Combat Evolved's script had her planned to speak with one, but was later removed in favor of Jen Taylor's natural voice.
