The Remnant War was a large conflict between the Covenant Remnant, lead by the High Prophet of Deliverance, and an alliance of factions opposed to him, including the United Nations Space Command, United Sangheili Republic and it's protectorates, Jiralhanae Alliance, the Kig-Yar Union, and the Yanme'e Hives. Opening the war with a colossal invasion of their enemies, they were soon bogged down by their enemies. Having grossly underestimated the strength of his foes, the Prophet of Deliverance saw the war turn on him, and his death would mark the end of the war.
