Serina

Serina is an artificial intelligence (AI) construct that is assigned to the, a modified Phoenix-class Colony Ship. She is set to be one of the main characters in the upcoming game Halo Wars, helping the players as they play the game.

Overview
Little is known about Serina at this point other than the fact that she acts as a Military Advisory AI, which may, or may not be, her only function. She is a smart AI (see quotes beneath), which is usually a sign of advanced memory capacity, like Cortana. In contrast, other AI's known throughout the Halo Canon exhibit only minor aspects of personality. Her avatar is a young female with long hair. Her clothes look like those worn on a farmland. This is most likely due to the fact that she was assigned to a Colony Ship that was sent to Harvest, an agricultural colony. Being a Smart AI, she may only have a few years of run time left if she has stayed near Harvest for the five years it took to get it back. Smart AI only have about 7 years of run time before they "think themselves to death".

Trivia

 * She is the first AI pictured in a game to wear clothes all over her body.
 * "Spinning up FTL drives" is a reference to Battlestar: Galactica, which uses this phrase constantly when the Fleet enters Lightspeed.
 * As said in the Halo Wars Manual, Serina seems to have a strange curiosity about chocolate.
 * Serina, knowing the crew of the Spirit of Fire may be on a one-way trip, manufactured and delivered fake emails from family members to the crew celebrating Valentine's day. No one ever suspected her of this deception.
 * She has a very sarcastic and non-caring nature, so non-caring infact that she even seems to disregard the lives of others (when the flood infect the Marines) and even her own, (when the Spirit of Fire is pulled inside the shield world) almost always responding with some curious or even dark joke.
