Isabel

Isabel was a UNSC logistics AI stationed on one of the many outposts on the Ark that were set up by the UNSC following the Battle of the Ark. Isabel befriended many of the workers and scientists who worked at the facility, and was present when the Banished attacked her outpost and slaughtered many of her friends. As a result, she jumped at the chance to join the crew of the Spirit of Fire to replace their previous AI, Serina, and fight back against the Banished.
