Subject 386

"You have been judged unclean! A scourge that must be burned away!"

- Subject 386 to Admiral Preston Cole

Subject 386, also known as the Groombridge Subject, was a Sangheili who 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 Preston Cole, First Lieutenant Richard Barclay, and Solipsil. It was from Subject 386 that the United Nations Space Command first learned why the Covenant were systematically exterminating humanity.

Subject 386's vitals flatlined at 0417 hours on December 25, 2530.

Because "Subject 386" is the human designation for this Sangheili, its real name, gender, and rank are unknown, although it is presumed to be male due to the fact that female Sangheili were never sent into combat and have never been seen by Humans.

The interrogation of Subject 386 was what convinced Admiral Cole of the necessity of keeping Earth and the remaining colonies hidden, which eventually became the Cole Protocol.
