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's groomed the former Spartan for a potential future as a flag officer. Later, she was hand picked by Parangosky to lead up a diplomatic mission to Sanghelios.
