Serina

Serina (SN: SNA 1292-4) was a second-generation AI construct assigned to the UNSC Spirit of Fire, a modified Phoenix-class colony ship. Serina was a military advisory smart AI. Created by Daedalia Technology, she was first activated on January 7, 2530. She was considered the greatest work of the time by the company. She was then assigned to the 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 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.
