Serina

Serina is an artificial intelligence (AI) construct that is assigned to the UNSC Spirit of Fire, a modified Phoenix-class Colony Ship. She is set to be one of the main characters in the upcoming 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. Serina also has a English accent.
