Editing Raid on Installation 08

John-117 crash-landed the damaged Pelican near the Installation's [[control room]]. At the same time, [[Avery Junior Johnson|Sergeant Major Avery Johnson]] landed the {{UNSCShip|Forward Unto Dawn}} on the Installation, far away from the control room. On foot, John, along with Cortana and Thel 'Vadam, made their way to the control room. The [[Gravemind]], having survived High Charity's explosion, sent waves of [[Flood dispersal pod]]s to prevent the activation of the Installation. The SPARTAN and the Arbiter fought through the Flood forces as they progressed to the top of the tower, with some assistance from the [[Sentinel]]s and Sergeant Johnson. Once at the top, the team met up with the sergeant, secured the area and entered the control room.

Once inside, the team hesitantly tried to activate the Installation immediately. [[343 Guilty Spark]], after realizing that firing the partially-completed installation would destroy the ring as well as the Ark, turned against the team. His initial attack mortally wounded the sergeant and blasted the former Arbiter out of the control room. John-117 was severely injured by the initial blast to the point of draining his shield. The SPARTAN was locked into a battle with the rampant Monitor and struggled to destroy it. The mortally wounded Sergeant Johnson took the rogue Monitor by surprise with his [[M6 Grindell/Galilean Nonlinear Rifle|Spartan Laser]], temporarily incapacitated the Forerunner construct. John, seizing the moment, used the sergeant's Spartan Laser to destroy Guilty Spark. John tended to the grievously wounded Johnson, whose dying words were  ''"send me out, with a bang."'' Cortana gave her condolences to John, briefly mourning the death of his friend, before firing the Installation using the Activation Index.

While ''Forward Unto Dawn'' was entering the Portal the field collapsed, severing the ship in two. The bow, with Thel inside, made it to the exit coordinates above Earth and crashed into the Indian Ocean. The stern section was less fortunate, being thrown out of the collapsing slipspace field on the way. John and Cortana were trapped in the wreckage as it drifted in space for several years, eventually being caught in the gravity of [[Requiem]], a Forerunner [[shield world]], in [[2557]]. This led to a series of [[Battle of Requiem|series of skirmishes]] as the Master Chief and Cortana struggled to find a way back to human space, opposed by a [[Jul 'Mdama's Covenant|reformed Covenant faction]] which had sought out Requiem and the [[Ur-Didact]]'s [[Promethean#Mechancical Prometheans|Promethean]] forces within the shield world.<ref>'''Halo 4'''</ref>

Some time after the battle, the UNSC dispatched the scouting vessel {{UNSCShip|Rubicon}} to investigate the Ark, following a failed attempt to deploy automated probes to the installation. At the Ark, the ''Rubicon'' deployed a number of [[remote contact team]]s to the Ark, which had been severely damaged by the incomplete ring's firing. Having detected an anomalous signal, one of the UNSC teams discovered the remains of Guilty Spark's tiny debris among the wreckage and brought him back to the ship.<ref>'''[[Eleventh Hour reports|Eleventh Hour report 4]]'''</ref> It turned out that the broken pieces of Spark were still partially intact, though his physical housing was irreversibly damaged. However, he managed to upload his consciousness into the ship's computers, purge its AI, render the crew unconscious, and set off on a quest to find the [[Librarian]].<ref>'''[[Halo: Primordium]]'''</ref> With the help of the crew of the ''[[Ace of Spades]]'' and now residing in an [[armiger]] body, Spark [[Mission to Mount Kilimanjaro|met with]] a personality imprint of the Librarian beneath [[Mount Kilimanjaro]] who helped Spark move on from his past and to a new future with the crew of the ''Ace of Spades''. However, Spark was hunted by [[ONI]] for the wealth of information he could provide them with.<ref>'''[[Halo: Renegades]]'''</ref>
