==Biography==
===Creation===
Serina was created by [[Daedalia Technology]], a [[Mars|Martian]] firm, on [[2530|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.{{Ref/Site|Id=CFFrosty|URL=https://www.halowaypoint.com/en-us/news/stay-frosty|Site=Halo Waypoint|Page=Canon Fodder - Stay Frosty|D=17|M=06|Y=2018}}

===UNSC ''Spirit of Fire''===
Serina replaced the previous shipboard AI of the ''Spirit of Fire'',{{Ref/Reuse|visual}} although she had a somewhat rocky period of acclimation to the ship's unorthodox crew.{{Ref/Reuse|CFFrosty}} 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.<ref name="Prima">'''[[Halo Wars: Official Strategy Guide]]'''</ref>

During [[2531]], Serina was present in the final battles of the [[Harvest campaign]] as well as the [[Battle for Arcadia]] and the [[Battle of Trove]], providing the crew with intelligence on the various situations they encountered. After the destruction of [[Trove]], 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 (B) Cyclops]], and weaponizing [[Cryonics|cryotechnology]] for UNSC use, like the [[ZAV-48 Frostraven]], the Tundra [[M88 Bison]] APC with a vacuum energy siphon, and the possibility of [[Hellbringers]] making use of cryoweapons.{{Ref/Reuse|CFFrosty}}

===Rampancy and end of service===
In [[2537]], six years after the events on [[Trove]], 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 [[Pod infector]] that had been nesting out of sight after the events on the Shield World, infecting her. Serina imposed lockdown on [[cryo chamber]] Foxtrot 7, and did not kill the parasite as the onset of her rampancy led her to be more interested in studying it, neglecting the possible danger it presented to the rest of the crew. She watched Maldini mutate into a [[Flood carrier form|carrier form]], breeding new infection forms and utilizing Maldini's knowledge of cryo chamber codes to awaken more crew members to infect. 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.<ref name="Something">'''[[Halo: Tales from Slipspace]]''', ''[[Something has Happened]]''</ref>

After these events, the now rampant Serina began her [[final dispensation]], set up by Anders,{{Ref/Reuse|Something}} on January 4, leaving one final status report for Captain Cutter upon his eventual awakening and was soon after completely terminated.{{Ref/Reuse|TS}} One of her final acts was quietly restarting production lines aboard the Spirit of Fire to replenish materiel that would later prove pivotal against the Banished.{{Ref/Reuse|Enc22}}

As part of the crew's hope to leave a trail, Serina created a series of preprogramed maintenance sheds and data drops. As per a promise she and Cutter made to [[John Forge]], Serina included in these a message Forge had recorded for his daughter. The UNSC recovered at least one of these with the data falling into the hands of [[343 Guilty Spark]] during his time with the UNSC. In [[2557]], Spark was able to explain to Rion her father's sacrifice and give her the message that Serina had kept her promise and left behind for Rion.<ref>'''[[Halo: Renegades]]''', ''pages 312-313''</ref>

==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 [[Trove]] - almost always responding to their peril with some curious remark or dark joke.{{Ref/Reuse|hw}} Although prone to sarcastic comments and exhibiting a seemingly uncaring attitude, she was more compassionate than she seemed.<ref name="timeline">'''Halo Wars''': ''Halo Timeline''</ref>

She also appeared to have a fascination with human relationships.<ref>'''Halo Wars''', ''game manual''</ref> 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.{{Ref/Reuse|timeline}}

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.{{Ref/Reuse|Prima}}

==Trivia==
*Serina was voiced by [[Wikipedia:Courtenay Taylor|Courtenay Taylor]] for ''[[Halo Wars]]'' and ''[[Halo Wars 2]]'',{{Ref/Reuse|hw}}<ref name="HW2">'''[[Halo Wars 2]]'''</ref> who also voiced an [[UNSC Army|Army trooper]] in ''[[Halo: Reach]]''.<ref>'''[[Halo: Reach]]''', ''[[Halo: Reach credits|credits]]''</ref>
*Serina's line "Spinning up FTL drive" may be a reference to the re-imagined ''[[Wikipedia:Battlestar Galactica (2004 TV series)|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.
*On July 25, [[2017]], Serina was added as a multiplayer leader for ''Halo Wars 2''.
