Subject 386

Subject 386, also known as the Groombridge Subject, was a Sangheili that was captured from a Covenant Assault Carrier that attempted to flee to the planetary surface during an engagement designated GB-5546. The Sangheili was later interrogated personally by Admiral Cole and First Lieutenant Richard Lionel Barclay. It was from Subject 386 that the United Nations Space Command first learned why the Covenant was systematically exterminating humanity.

Because "Subject 386" is the human designation for this Sangheili, it is unknown what its real name is.
