Serin Osman

Captain Sarah Osbun is a human senior officer of the UNSC Navy and a field agent in the Office of Naval Intelligence. Abducted in 2517 as a SPARTAN-II candidate, Osbun failed the augmentation process and was recruited into ONI. Considered as a "protege" to Admiral Margaret Parangosky, the Director of Naval Intelligence, she has groomed the former Spartan for a potential future as her successor. Later, she was hand picked by Parangosky to lead up a diplomatic mission to Sanghelios. For the mission, she was paired with the AI Black Box. At first, she reacted to the eccentric AI with wariness and suspicion, but learned to trust him over time.
