Admiral Margaret Orlenda Parangosky is a prominently featured character in the Halo universe. She is the Commander-in-Chief of the Office of Naval Intelligence. Though Admiral Parangosky is a member of the UNSC, she had played a somewhat villainous role in some of the novels she appears in and is more of an anti-hero, such as in Halo: Glasslands, where it is revealed that she is distrustful of the Sangheili, wanting to wipe them out and colonize Sangheilios.
