Chief uncovers a [[Covenant]] [[Covenant religion#The Great Journey|plot]] to fire the weapon, and sacrifices the ''Autumn'' to destroy the Halo ring."
*'''System:''' "Pursuing the Covenant [[Solemn Penance|flagship]] after an [[Battle of Earth|attack on earth]], Spartan 117 arrives at [[Installation 05]] to find the Covenant erupting into [[Great Schism|civil war]]. After preventing the Covenant from firing the ring, 117 followed them back to Earth in search of a Forerunner installation that could activate all the galaxy's Halos." 
*'''System:''' "The Covenant arrive at [[Earth]] and open [[Excession|a portal]] to [[Installation 00|the Ark]], an [[Intergalactic space|extragalactic]] Forerunner installation that can fire the Halo Array. Spartan 117 unites [[Swords of Sanghelios|a joint Covenant]]/UNSC team to pursue the Covenant to the Ark, where he successfully destroys the Installation and prevents the rings from being used."
*'''System:''' "When Spartan 117 attempts to escape from the Ark aboard the ''[[UNSC Forward Unto Dawn|Forward Unto Dawn]]'', the [[slipspace portal]] that the ship is passing through collapses." 
*'''System:''' "Aboard the aft section of the dawn, SPARTAN-117 is placed into [[cryo]] sleep pending recovery by UNSC forces. A.I. Cortana to remain active as long as is technically feasible."

*'''Unknown voice:''' "[[Catherine Halsey]] Research excerpt, 11 February [[2550]]."
*'''Halsey:''' "A interesting factor here isn't that H-1 disabled the viral termination code I had implanted in [[Cortana|her]] matrix. These metrics imply its success wasn't just unlikely, but that even the acceptance of the 7-year life cycle estimates may not apply." 
*'''Halsey:''' "Thus far, I've determined that the unique circumstances of her creation have triggered what I can only refer to as a recessive variant in the [[A.I.]] seed." 
*'''Halsey:''' "As her architect, I'm currently at a loss as to the origin of the development of this rogue element. Very curious."<ref name="Requiem">'''Halo 4''', campaign level ''Requiem''</ref>
