SPARTAN-091, born as Jared (last name unknown), and referenced in ONI files as Codename ORPHEUS, was a special warfare operator of UNSC Special Warfare Group SPARTAN that participated with honorable distinction during the Human-Covenant War, the Memory Crisis, the PATRIOT Initiative, Operation REJUVENATION, and countless other post-war campaigns. He was noted by historians to have served as one of ONI's own classified SPARTAN-IIs, running countless operations for them. He fought in some of mankind's most infamous confrontations, such as the Battle of New Bremerhaven, the Battle of Miridem, and the Defense of Earth, and was conspicuously involved with the UNSC Office of Naval Intelligence, prosecuting morally-dubious covert actions and participating in the training of Kimberly Ivy Blackburn. While always an exceptional fighter and glorified by humanity for his defense of mankind, he remained resigned and distant for a long time, opening up only to his close friends.
