The '''Battle of the Ark''' was a large battle between the [[UNSC]]-[[Covenant Separatist]] alliance, the [[Covenant Loyalists]], the [[Flood]]<ref>''[[Halo 3]]'', levels ''[[The Ark (Level)|The Ark]]'' and ''[[Halo (Halo 3 Level)|Halo]]''</ref>, and [[Forerunner]] [[Sentinel]]s. It was the final battle of the second [[Flood]] outbreak, the [[Human-Covenant War]] and the [[Covenant Civil War]]. <ref>''[[Halo 3]]'', final cutscene</ref> The Battle of the Ark and the last stand of the [[Covenant]] marked one of the few major engagements in the entire war that the Covenant were on the defensive.

==Background==
===Battle of Installation 04===
During the [[Battle of Installation 04]], [[Cortana]] intercepted the [[Installation]]'s [[Index]] as it was being inserted by [[Spartan-117]].  She continued to hold on to it after she had been removed from the Installation's [[Control Room]].  She also had spent over twelve hours inside the Control Room's computer, gaining an incredible amount of information about the [[Halo]] installations, making her possibly the most knowledgeable regarding the operation of the Halo rings, the Forerunners and the Ark perhaps even more so than [[343 Guilty Spark (Monitor)|343 Guilty Spark]] who admitted he was quite ignorant of the Forerunner structures beyond Installation 04.

===Battle of Installation 05===
The [[Battle of Installation 05]] included many events that would become major factors in the Battle of Installation 00.

The UNSC [[AI]], [[Cortana]], remained aboard the Covenant holy city, ''[[High Charity]]'' as the Flood and its central consciousness, the [[Gravemind]], took control of it.  From there, the Gravemind interrogated her, and she willingly answered its questions.

The aborted activation of Installation 05 had set all of the Halo rings to standby, where they could be activated from the central location of the [[Ark]].

Finally, the Covenant Civil War and the [[Human]]-Separatist alliance began in the space around Installation 05.

===[[Second Battle of Earth]]===
The [[High Prophet of Truth]] had arrived on [[Earth]] and began digging for a Forerunner structure.  Eventually they uncovered and activated it, opening a [[Portal]] that would take them to the Ark a Forerunner structure from which Truth can fire all of the Halo installations at once. As he departed through the Portal, a Flood captured ship arrived on Earth and crashed. From it, they were able to extract a message from Cortana, alerting them that ''High Charity'' was heading for Earth and indicating that the solution to the problem of the Flood lay beyond the portal.

While [[Lord Hood]] was suspicious of [[Cortana]]'s warning and objected to going through the portal, [[Commander]] [[Miranda Keyes]], Spartan-117 and [[Ship Master]] [[Rtas 'Vadum]] all indicated their wish to proceed through the Portal.  Lord Hood gave  Miranda Keyes command of the ''[[Forward Unto Dawn]]'' for the human commitment to the mission and the fleet of ships chased after the High Prophet of Truth.

==The Battle==
[[Image:923831-Full.jpg|thumb||left|250px|The Sangheili Fleet of Retribution engages the Loyalist fleet over The Ark]]
The High Prophet of Truth, having successfully activated the artifact in [[Voi]], left Earth through a [[Slipspace]] portal to the Ark, a Forerunner structure that can be used to fire all of the Halo installations at once.  Despite Lord Hood's urging, Commander Keyes took the ''Forward Unto Dawn'' with a small fleet of Separatist [[Cruiser]]s led by the [[Assault Carrier]] ''[[Shadow of Intent]]'' and proceeded through the Slipspace portal, arriving at the Ark. The Separatists immediately engaged the [[Brute]] fleet stationed to protect the [[Prophet]] while the ''Dawn'' and the ''[[Aegis Fate]]'' deployed the [[Master Chief]] and [[Orbital Drop Shock Trooper]]s in six [[Pelicans]] to locate Truth.  Despite being outnumbered three-to-one in space, the Separatist fleet made short work of the Loyalist space forces, likely due to the [[Elites]]' and Humans' superior tactical skills. The Brute's tactical ineptness can be heard in a radio transmission, saying "''No! Shoot the Carrier!''" The Covenant Loyalist Fleet had been destroyed and the only Loyalists left alive were Truth and his forces on the Ark. Also, presumably Truth landed the [[Forerunner Dreadnought]] on the Ark although it was never seen again and was specifically said not to take part in the battle above the Ark. 

[[Image:H3 E3 Orbital Battle.jpg|thumb|left|250px|The battle raging over the Installation 00]]

Five of the Pelicans deployed by the human [[Frigate]]s had made it to the Ark. The Master Chief and four [[ODST]]s were deployed, ambushing a group of Brutes, [[Grunt]]s, and [[Jackal]]s listening to a message from Truth. They then proceeded to ambush another group of Covenant Loyalists building an Anti-Aircraft Gun. They entered a small cave, where the Chief first accessed the Forerunner [[Terminals|Terminal]] Network. On the other side of the cave they met a pair of [[Marine]] survivors from a second shot down Pelican and witnessed a [[Longsword]] fighter crashing.  After being informed of a possible landing zone for the ''Forward Unto Dawn'', the humans ambushed the Brutes and Grunts searching the crashed Pelican, then destroyed a pair of Brute [[Prowlers]] that attacked. Now with [[Mongoose]]s and Prowlers, they continued past the crashed Longsword, a pair of [[HEV]]s that had landed and had the ODST's which had once occupied them killed once they left their pods, and a crashed [[Phantom]] to a battle between Covenant and Sentinels outside a Forerunner barrier. [[Avery J. Johnson]] informed that he had spotted a structure that was similar to the [[Cartographer]] of Installation 04 on the other side of the wall, and Keyes set it as their objective. The ''Dawn'' would need to land first however. After meeting another group of Marines being attacked, the vehicles led by the Chief then moved to the sighted Landing Zone, which was occupied by a pair of Anti-Air Wraiths. After they cleared the LZ, the ''Dawn'' disengaged from the space battle and dived onto the surface of the installation, landing safely.

[[Image:Ark Level Scorpion.jpg|thumb|left|250px|UNSC ground forces battling in the desert]]

From the ''Dawn'''s hangar, the Master Chief, ODSTs, and Marines were reinforced with three [[Scorpion]] tanks and a [[Warthog]]. The human force then fought their way through a large reinforcements force back to the Forerunner wall. The Chief went through the upper, smaller doorway while the armor and vehicles (reinforced with one more Warthog and a [[Gauss Warthog]]) went through the larger, lower doorway.  After activating a light bridge the [[Spartan]] went through the wall, only to see a [[Scarab]] and a Loyalist armored force destroy the Warthogs. He then fought his way to the lower doorway, which then finally opened fully, letting the tanks through. [[Sergeant]] [[Pete Stacker]] and the Chief led the [[Scorpions]] and a [[Warthog]] through two Loyalist defense lines of [[Choppers]], [[Ghosts]], [[Wraiths]], and infantry with heavy weapons, reinforced by a Phantom.  When the Scarab returned, the humans then proceeded to destroy it, plus the Choppers and infantry reinforcing it. By now the Elites had defeated the entire Loyalist space fleet. The ''[[Shadow of Intent]]'', landed near the Cartographer. The ''Aegis Fate'' had landed on a Brute-controlled [[Sandtrap|desert Forerunner facility]] and demolished the forces there. Rtas Vadum likely ordered all his remaining ships except ''Shadow of Intent'' to go back to [[Earth]] and wait for his return.

[[Image:Trident11.jpg|thumb|left|250px|[[Human]] and Elite forces begin their assault on Truth.]]

[[343 Guilty Spark (Monitor)|343 Guilty Spark]], now working with the UNSC-Separatist alliance, led [[Spartan-117]] and the Arbiter, plus a pair of Marines, to the Ark's Cartographer.  Fighting their way through several incompetent forces that were asleep, they get back outside where they pinpoint the Prophet's location.  By then Truth had already holed himself in a secure facility in the core of the Ark and had activated a large barrier around the entire core to ward off the attacking forces. After discovering Truths location, the UNSC-Separatist troops were attacked by a large Loyalist air force. Johnson led the air battle against them, and the Arbiter stole a [[Banshee]] to help him.  The Chief, with the pair of Marines, fought his way past a [[Brute Chieftain]] and his squad and a group of [[Stalker Brute]]s. He then dueled with a [[Brute Chieftain]] and defeated squad of [[Jump Pack Brute]]s before being picked up by Pelican [[Kilo 23]] after the Loyalist air force was dealt with. The humans and Elites set forth to attack Truth to stop him from activating the rings.

[[Image:Banshee cov.jpg|thumb|left|250px|Loyalist air forces being defeated]]

The UNSC ground forces, carried in five Pelicans, along with Separatist reinforcements in a pair of green Phantoms, assaulted three emitter pylons that powered a small section of the barrier. The Master Chief and a pair of ODSTs were deployed a distance from the first tower by a Pelican after hostile fire shot down a second Pelican carrying Marines and a Warthog. The crashing Pelican also took out the ODST's Warthog. The Arbiter and Elites assaulted the second tower.  Sergeant Johnson took four Marines and attacked the final tower. Clearing the Loyalists heavy weapons on the beach, a new Warthog and a Mongoose were deployed and taken through heavy resistance to the tower. Clearing it, the Chief learned that the Separatists had taken down the second tower, but Johnson had been ambushed by enemy reinforcements. The Chief returned to the beach, commandeered a [[Hornet]] and helped destroy Loyalist Banshees and a Phantom, securing air control for the UNSC-Separatist forces outside the barrier. Destroying the Brute defenders outside the third tower with Hornets and Pelicans, Master Chief, the Arbiter, and a team of five Elites discovered the corpses of the Marine team, except for Johnson's. When the defending forces were eliminated and the barrier deactivated, the ''Shadow of Intent'' began its attack on Truth.  At the same time the former Covenant city ship ''High Charity'' arrived from Slipspace and crashed on the Ark.  Debris spread from the city ship heavily damaged the ''Shadow of Intent'' and helped spread a new Flood infestation on the Ark as a means to stop Truth and to be safe from the [[Halo]] activation array. Keyes insisted that this would only pressure Truth into activating the rings, and ordered the remaining forces to attack him directly.

Fighting through an infestation of the Brutes they had just killed and Johnson's Marines, the Elites and the Chief met up with Sergeant Stacker's Marines, supported by a Scorpion, a Gauss Warthog, and a Mongoose. The humans and Elites fought through the cliffs into the [[Citadel]] where the Halos could be activated was located. The Loyalists attempted to reinforce their troops by a large amount of Phantom transports gathered from around the installation, but the UNSC air forces countered this by attacking the Phantoms and their Banshee escorts with Hornets and Pelican Gunships. The ground forces managed to destroy the remaining Loyalist armor on the mountainside. Given another Gauss Warthog and air support from a flight of Hornets and a Pelican, the Marines destroyed Banshees,  Ghosts, a Prowler, plus a pair of Scarabs dropped in front of the Citadel by Brutes. After the destruction of the Scarabs, the Loyalists had lost their grip on the Citadel area. Without any heavy support, Spartan-117 and the Arbiter personally attacked the facility where Truth was to activate the Halo installations.[[Image:Scarab explodes.jpg|thumb|right|250px|The Loyalist ground forces are defeated]]

[[Sergeant Major]] Johnson, who had disappeared during the assault, was in fact captured by Truth's forces and was being tortured into pressing the final switch to activate the other Halos. With Spartan-117 and the Arbiter too far away to stop High Prophet of Truth, Commander Keyes grabbed a Pelican dropship and crashed into the facility to rescue Johnson, but was killed soon after by Truth himself. However, her actions delayed Truth long enough for Spartan-117 and the Arbiter to stop him. The [[Gravemind]] dispatched Flood forces to assist Spartan-117 and the Arbiter in preventing the Halos' activation and the Arbiter personally killed Truth.  However, the Gravemind betrayed them and while Johnson managed to escape with Commander Keyes' body in the Pelican, Spartan-117 and the Arbiter had to fight their way outside. 
[[Image:230px-End_Truth.jpg|thumb|right|Arbiter killing the Prophet of Truth.]]
343 Guilty Spark had managed to facilitate the making of a new Halo through the Ark, explaining that a tactical pulse from it would eliminate the Flood infestation.  However, this new Halo lacked an Activation Index.  The only way they could get another Index was to rescue Cortana from ''High Charity'' since she still possessed the Index from Installation 04. 

Johnson picked up the Arbiter and the Chief while Guilty Spark went off to the new Installation. The party then headed to the Shadow of Intent, where Johnson and the Ship Master rounded up the UNSC and Sanghelli forces. Meanwhile, the Arbiter and Master Chief headed towards High Charity in tow separate Banshees. Through a tough battle, [[Spartan-117]] and the Arbiter successfully entered the ruins of ''High Charity'' and recovered [[Cortana]], using a partly-damaged Pelican to escape while ''High Charity'' was destroyed as its reactors went critical after the they blasted them.

With the Index secure, the Arbiter ordered that the remaining UNSC forces relocate to the Separatist ships and escape back through the Slipspace portal to Earth while he, Spartan-117, and Sergeant Major Johnson moved in on the Control Room of the incomplete Halo. The ''Dawn'' was left behind for them to use to escape. By now what was left of the Gravemind had relocated to the new Halo. The three heroes with 343 Guilty Spark made it through waves of Flood to the Control Room. 343 Guilty Spark explained that the new Halo would be ready to fire within days, to which the group, particularly Johnson, protested. When Guilty Spark informed the three that activating Halo now would destroy both the Ark and the installation, Johnson told him to "deal with it" and prepared to activate the ring. 

Unwilling to let "his" ring be destroyed again, 343 Guilty Spark went rampant, killing Johnson and attacking Spartan-117 and the Arbiter. However, with the help of a dying Sergeant Johnson and his [[Spartan Laser]], Spartan-117 managed to destroy Guilty Spark and start the firing sequence of the new Halo. He and the Arbiter then took Johnson's Warthog and rushed towards the ''Dawn'' as the incomplete Halo powered up and started breaking apart. The two drove their way through hordes of battling Flood and [[Sentinel]] drones, with the world literally falling to pieces around them. The two heroes made it to the ''Dawn'', where the Arbiter was almost crushed by a Scorpion Tank due to the sudden acceleration of the ship. Agility and a pair of crates saved him. He made his way to the bridge of ''Dawn'' and took her into Slipspace just as the new Halo fired, with Master Chief almost being crushed by the same tank which descended through the cargo hold and into space. However, the Slipspace portal collapsed as the ''Dawn'' entered it and while the forward half with the Arbiter made it to Earth, the rear half fell out of Slipspace with Cortana and Spartan-117 floating into the dark abyss.

With Truth dead, the Halos deactivated, and the Flood destroyed, the Battle of the Ark ended the Human-Covenant War.  A monument was erected in [[New Mombasa]] in remembrance of those who gave their lives in the war including Spartan-117 who is labeled [[MIA]].  The Arbiter and his brethren then departed Earth for [[Sanghelios]].

==Aftermath==

{{Quote|Send me out, with a bang.|[[Sergeant Johnson|Johnson]]'s last words}}

===Installation 00 and the Flood===
It is assumed that the firing of the Halo ring either severely damaged or destroyed the Ark while killing the Flood forces around Installation 00, including the Gravemind commanding the massing Flood amid the battle.

===''Forward Unto Dawn''===
The Portal between [[Installation 00]] and Earth collapsed while ''[[Forward Unto Dawn]]'' was still inside it.  As a result, the ship was cut in half the front arriving at Earth and the back half being lost in space. The Arbiter, sitting on the bridge at the time, was part of the front half but, without any engines, soon crashed. However, Spartan-117 and Cortana were in the rear half and were missing.

It is known that Cortana and [[Spartan-117]] survived the Portal's collapse.  Spartan-117 went into cryo-tube while Cortana sent out a signal indicating their status.  It is unknown if their message was ever received or if they were rescued. The amount of time that passed in the interim is unknown, and it is also unknown if Cortana succumbed to [[AI]] [[Rampancy]] or even survived the course of the journey, as UNSC [[Smart AI]] minds become too interlinked and "think themselves to death" after approximately seven years of operational service.

===Legacy===
A monument was made near the town of Voi where the Forerunner artifact had been built.  It reads "''In memory of those fallen in the defense of Earth and her Colonies. [[March 3, 2553]].''" On it were the pictures of the most outstanding UNSC personnel who went through the Portal but did not return.  Spartan-117 is honored on it by a "117" scratched onto the monument and a [[Master Chief Petty Officer]] badge taped on the monument.

As he departed through the Portal, the Flood-captured ship ''[[Indulgence of Conviction]]'' arrived on Earth and crashed, though its arrival was followed by a portion of the Sangheili [[Fleet of Retribution]] of at least 16 [[Covenant starship|warships]], led by [[Shipmaster]] [[Rtas 'Vadum]].{{Ref/Level|Halo 3|[[The Storm]]}}{{Ref/Map|Id=heretic|H3|Heretic}} From it, John-117 was able to extract a message from [[Cortana]], alerting them that ''High Charity'' was heading for Earth and cryptically stating that [[Installation 08|the "solution" to the problem of the Flood]] lays beyond the portal.{{Ref/Reuse|floodgate}}

Despite being outnumbered three-to-one, Rtas 'Vadum declared that they were fairly matched, and the Sangheili ships and the ''Forward Unto Dawn'' promptly engaged Truth's fleet. In the ensuing [[space warfare|space battle]], the Jiralhanae and Sangheili cruisers blended into each other.{{Ref/Level|H3|The Ark (level)|The Ark|Quote=Their cruisers mixed with ours!

-{{Main|Battle for the Cartographer (Installation 00)}}
-[[File:Ark Level Scorpion.jpg|thumb|left|300px|UNSC ground forces battling in the desert.]]
-The Pelicans from the ''Forward Unto Dawn'' arrived on the surface of the Ark, where they deployed [[UNSC Marine Corps|Marines]] and UNSC vehicles to search for a landing zone for the ''Dawn''. ''[[Kilo 023]]'' and another Pelican deployed [[Master Chief Petty Officer]] John-117 and a squad of [[Orbital Drop Shock Trooper|ODSTs]] at a cliff edge, near a series of Forerunner structures built into the desert terrain. Nearby, a third Pelican, which carried a [[M12 Chaingun Warthog|Warthog]], two [[M274 Mongoose|Mongooses]], and [[UNSC Marine Corps|Marines]] including [[Chips Dubbo]], found a wide cliff which could serve as a landing zone for the ''Dawn'', but the Pelican was shot down by Covenant anti-air defenses.{{Ref/Reuse|theark}}
-With support from his accompanying ODST squad and his [[SRS99D-S2 AM sniper rifle]], John-117 cleared out two Covenant camps of Jiralhanae, Unggoy, and Kig-Yar. At the second camp, they disrupted the Covenant's efforts to assemble a [[Skar'wa-pattern Mantis|Mantis]]. Emerging on the other side of the Forerunner structures, they linked up with Dubbo and other survivors seeking refuge from the downed Pelican, where a lance of Covenant searched for survivors. Dubbo informed John-117 of the potential landing zone for the ''Dawn''. Upon defeating the Covenant patrol at the Pelican, a pair of [[Qavardu Workshop Prowler|Prowlers]] arrived at the area, but their operators were eliminated by the UNSC. Salvaging both UNSC and Covenant vehicles, John-117 and his team advanced into the Covenant-occupied canyon. At this point, the Covenant have set up an attack force of infantry and {{Pattern|Rizsheda|Shade}}s at a nearby [[Forerunner]] wall, which was defended by [[Aggressor Sentinel]]s. John-117 and his team eliminated the Covenant attackers, and the Sentinels, recognizing the humans as [[Reclaimer]]s, withheld their attacks. [[Sergeant Major]] [[Avery Johnson]], onboard ''Kilo 023'', spotted a structure that was similar to the [[Cartographer]] of [[Installation 04]] on the other side of the wall, and Keyes set the structure as the objective.{{Ref/Reuse|theark}}
+==The Battle==
+[[Image:923831-Full.jpg|thumb||left|250px|The Sangheili Fleet of Retribution engages the Loyalist fleet over The Ark]]
+The High Prophet of Truth, having successfully activated the artifact in [[Voi]], left Earth through a [[Slipspace]] portal to the Ark, a Forerunner structure that can be used to fire all of the Halo installations at once.  Despite Lord Hood's urging, Commander Keyes took the ''Forward Unto Dawn'' with a small fleet of Separatist [[Cruiser]]s led by the [[Assault Carrier]] ''[[Shadow of Intent]]'' and proceeded through the Slipspace portal, arriving at the Ark. The Separatists immediately engaged the [[Brute]] fleet stationed to protect the [[Prophet]] while the ''Dawn'' and the ''[[Aegis Fate]]'' deployed the [[Master Chief]] and [[Orbital Drop Shock Trooper]]s in six [[Pelicans]] to locate Truth.  Despite being outnumbered three-to-one in space, the Separatist fleet made short work of the Loyalist space forces, likely due to the [[Elites]]' and Humans' superior tactical skills. The Brute's tactical ineptness can be heard in a radio transmission, saying "''No! Shoot the Carrier!''" The Covenant Loyalist Fleet had been destroyed and the only Loyalists left alive were Truth and his forces on the Ark. Also, presumably Truth landed the [[Forerunner Dreadnought]] on the Ark although it was never seen again and was specifically said not to take part in the battle above the Ark.
-The landing zone was occupied by Ghosts, a [[Zurdo-pattern Wraith|Wraith]], several [[Covenant watchtower]]s, Jiralhanae and Unggoy infantries, and two [[Ogab'd-pattern anti-aircraft Wraith|Anti-Air Wraiths]] that were firing into an aerial battle between [[Type-26 Banshee|Banshees]] and [[AV-14 Hornet|Hornets]]. John-117 and his team, having gathered more Marine survivors, cleared the landing zone, allowing the ''Forward Unto Dawn'' to disengage from the space battle and descend to the surface of the installation, landing safely. From the ''Dawn''{{'}}s hangar, the UNSC was reinforced with three [[M808C Scorpion|Scorpion]] tanks, a [[M12 Chaingun Warthog|Warthog]] and a unit of Marines led by [[Gunnery Sergeant]] [[Marcus Stacker]]. With [[343 Guilty Spark]] having arrived to guide them, the mechanized force then fought their way back to the Forerunner wall, destroying numerous Covenant vehicles and ground troops. The Covenant had retaken the wall, bolstering their defenses with Wraiths, Choppers, and Shade turrets, but they failed to deter the UNSC's progress.{{Ref/Reuse|theark}}
+[[Image:H3 E3 Orbital Battle.jpg|thumb|left|250px|The battle raging over the Installation 00]]
-After entering the wall and emerging from the other side, the UNSC encountered a [[Deutoros-pattern Scarab|Scarab]]. Although the Scarab quickly left the area, the canyon leading from the wall to the Cartographer was defended by a battalion-sized force of Covenant heavy armor, including Choppers, Ghosts, Wraiths, and infantry with [[Pez'tk-pattern fuel rod gun|heavy weapons]], reinforced by a Phantom. Two of the three Warthogs, which emerged from the wall first, were quickly overwhelmed, and their operators were killed. A single [[M12G1 Gauss Warthog]], taking a winding path to the side, was harassed by Ghosts and lost its gunner, though it regrouped with John-117, who had left the group earlier when they travel across the wall. The Spartan commandeered the vehicle and rejoined the Scorpion tanks. John-117 and Stacker then led the Scorpions against the Covenant armor. When the UNSC forces broke through the Covenant defenses, the Scarab returned to the area, with Choppers as its escorts. Stacker ordered Marines from Bravo unit to flank the Scarab to cover John-117's assault on the Scarab. They succeed, with John-117 personally taking down the Scarab. After the Scarab's destruction, the ''[[Shadow of Intent]]'' arrived at the Cartographer, and Rtas 'Vadum announced that his fleet had destroyed Truth's fleet.{{Ref/Reuse|theark}}
+Five of the Pelicans deployed by the human [[Frigate]]s had made it to the Ark. The Master Chief and four [[ODST]]s were deployed, ambushing a group of Brutes, [[Grunt]]s, and [[Jackal]]s listening to a message from Truth. They then proceeded to ambush another group of Covenant Loyalists building an Anti-Aircraft Gun. They entered a small cave, where the Chief first accessed the Forerunner [[Terminals|Terminal]] Network. On the other side of the cave they met a pair of [[Marine]] survivors from a second shot down Pelican and witnessed a [[Longsword]] fighter crashing.  After being informed of a possible landing zone for the ''Forward Unto Dawn'', the humans ambushed the Brutes and Grunts searching the crashed Pelican, then destroyed a pair of Brute [[Prowlers]] that attacked. Now with [[Mongoose]]s and Prowlers, they continued past the crashed Longsword, a pair of [[HEV]]s that had landed and had the ODST's which had once occupied them killed once they left their pods, and a crashed [[Phantom]] to a battle between Covenant and Sentinels outside a Forerunner barrier. [[Avery J. Johnson]] informed that he had spotted a structure that was similar to the [[Cartographer]] of Installation 04 on the other side of the wall, and Keyes set it as their objective. The ''Dawn'' would need to land first however. After meeting another group of Marines being attacked, the vehicles led by the Chief then moved to the sighted Landing Zone, which was occupied by a pair of Anti-Air Wraiths. After they cleared the LZ, the ''Dawn'' disengaged from the space battle and dived onto the surface of the installation, landing safely.

-Encountering resistance from Jiralhanae and Kig-Yar on the way, John-117 climbed a series of ramps towards the entrance to the Cartographer. At the top, he met with [[Thel 'Vadam]], who dismounted from ''Kilo 023'' along with a pair of Marines. While Commander Keyes assembled an air support force to prevent Covenant reinforcements, 343 Guilty Spark unlocked the sealed door at the entrance, allowing John-117 and Thel 'Vadam to advance inside. Their arrival caught most of its Covenant occupants off-guard, and they eventually arrived at an exterior platform hosting the Cartographer terminal. The Chief and 343 Guilty Spark accessed the terminal, learning the installation as the "Ark" and that Truth had already fortified himself at [[Installation 00 Citadel|the core of the Ark]], where he could remotely activate the entire Halo Array. Furthermore, Truth had activated a large barrier around the entire core to ward off the attacking forces.{{Ref/Reuse|theark}}
+From the ''Dawn'''s hangar, the Master Chief, ODSTs, and Marines were reinforced with three [[Scorpion]] tanks and a [[Warthog]]. The human force then fought their way through a large reinforcements force back to the Forerunner wall. The Chief went through the upper, smaller doorway while the armor and vehicles (reinforced with one more Warthog and a [[Gauss Warthog]]) went through the larger, lower doorway.  After activating a light bridge the [[Spartan]] went through the wall, only to see a [[Scarab]] and a Loyalist armored force destroy the Warthogs. He then fought his way to the lower doorway, which then finally opened fully, letting the tanks through. [[Sergeant]] [[Pete Stacker]] and the Chief led the [[Scorpions]] and a [[Warthog]] through two Loyalist defense lines of [[Choppers]], [[Ghosts]], [[Wraiths]], and infantry with heavy weapons, reinforced by a Phantom.  When the Scarab returned, the humans then proceeded to destroy it, plus the Choppers and infantry reinforcing it. By now the Elites had defeated the entire Loyalist space fleet. The ''[[Shadow of Intent]]'', landed near the Cartographer. The ''Aegis Fate'' had landed on a Brute-controlled [[Sandtrap|desert Forerunner facility]] and demolished the forces there. Rtas Vadum likely ordered all his remaining ships except ''Shadow of Intent'' to go back to [[Earth]] and wait for his return.
-After learning of Truth's location, they were attacked by a Phantom, one of the many aircrafts from the Covenant's aerial attack on the Cartographer. Thel 'Vadam drew the Phantom's fire, allowing the Chief to escort Spark clear. 'Vadam then hijacked a Banshee and joined Keyes' air support to repel the Covenant attack. Notified by Dubbo, John-117 was instructed to descend to a platform underneath the Cartographer for extraction. The Spartan fought his way down, defeating a [[Jiralhanae War Chieftain|War Chieftain]], his [[Jiralhanae Bodyguard|Bodyguards]], and a group of [[Cloaking|camouflaged]] [[Jiralhanae Stalker]]s along the way.{{Ref/Reuse|theark}} At the platform underneath the Cartographer terminal, [[Jiralhanae Chieftain]] [[Cethegus]] regrouped with the [[Jiralhanae Jumper|Jumpers]] from his pack. Cethegus and the members of his pack were charged with halting the UNSC-Sangheili progress. Believing he would ascend to the title of Chieftain of the Jiralhanae for killing the Spartan, the ambitious Chieftain challenged John-117 to a duel.{{Ref/Site|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-brute-force|Site=Halo Waypoint|Page=Canon Fodder - Brute Force|D=11|M=10|Y=2021}} Despite being outnumbered, John-117 defeated Cethegus' pack as well as two Kig-Yar marksmen. Meanwhile, the Hornets under Keyes' command had destroyed the Banshee attack force, putting an end to the conflict at the Cartographer.{{Ref/Reuse|theark}}
+[[Image:Trident11.jpg|thumb|left|250px|[[Human]] and Elite forces begin their assault on Truth.]]
-''Kilo 023'' arrived to pick up John-117, but a massive swarm of Sentinels approached the Pelicans. Initially, the UNSC prepared to attack, but they stopped when 343 Guilty Spark asked them not to attack the Sentinels, stating that the Sentinels had a "priority task" of unknown nature. Instead of attacking, the Aggressors flew off into the distance, and the UNSC and Sangheili followed suit, making their way to the Installation 00 Citadel to stop the Prophet of Truth.{{Ref/Reuse|theark}}
+[[343 Guilty Spark (Monitor)|343 Guilty Spark]], now working with the UNSC-Separatist alliance, led [[Spartan-117]] and the Arbiter, plus a pair of Marines, to the Ark's Cartographer.  Fighting their way through several incompetent forces that were asleep, they get back outside where they pinpoint the Prophet's location.  By then Truth had already holed himself in a secure facility in the core of the Ark and had activated a large barrier around the entire core to ward off the attacking forces. After discovering Truths location, the UNSC-Separatist troops were attacked by a large Loyalist air force. Johnson led the air battle against them, and the Arbiter stole a [[Banshee]] to help him.  The Chief, with the pair of Marines, fought his way past a [[Brute Chieftain]] and his squad and a group of [[Stalker Brute]]s. He then dueled with a [[Brute Chieftain]] and defeated squad of [[Jump Pack Brute]]s before being picked up by Pelican [[Kilo 23]] after the Loyalist air force was dealt with. The humans and Elites set forth to attack Truth to stop him from activating the rings.

The Master Chief and a pair of ODSTs were deployed a distance from the first tower by a Pelican after hostile fire shot down a second Pelican carrying Marines and a Warthog. The crashing Pelican also took out the ODST's Warthog. The Arbiter and Elites assaulted the second tower.  Sergeant Johnson took four Marines and attacked the final tower. Clearing the Loyalists heavy weapons on the beach, a new Warthog and a Mongoose were deployed and taken through heavy resistance to the tower. Clearing it, the Chief learned that the Separatists had taken down the second tower, but Johnson had been ambushed by enemy reinforcements. The Chief returned to the beach, commandeered a [[Hornet]] and helped destroy Loyalist Banshees and a Phantom, securing air control for the UNSC-Separatist forces outside the barrier. Destroying the Brute defenders outside the third tower with Hornets and Pelicans, Master Chief, the Arbiter, and a team of five Elites discovered the corpses of the Marine team, except for Johnson's. When the defending forces were eliminated and the barrier deactivated, the ''Shadow of Intent'' began its attack on Truth.  At the same time the former Covenant city ship ''High Charity'' arrived from Slipspace and crashed on the Ark.  Debris spread from the city ship heavily damaged the ''Shadow of Intent'' and helped spread a new Flood infestation on the Ark as a means to stop Truth and to be safe from the [[Halo]] activation array. Keyes insisted that this would only pressure Truth into activating the rings, and ordered the remaining forces to attack him directly.

-On the same day, December 11, 2552, the UNSC-Sangheili alliance arrived at vicinity of the core of Installation 00. AV-14 Hornets were sent in to contest for airspace around the barrier. An assault team, composed of five Pelican dropships and a pair of Sangheili Phantoms, began their attack on a trio of [[Barrier tower|towers]] that, once disabled, would deactivate the barrier protecting the Citadel in which the Prophet of Truth was located. Two Pelicans, including ''Kilo 023'' which carried John-117 and an ODST squad led by Gunnery Sergeant Stacker, would attack the Tower One. The Phantoms, which carried Thel 'Vadam and his Sangheili (including [[N'tho 'Sraom]] and [[Usze 'Taham]]),{{Ref/Novel|HitD|Chapter=?}} would assault the middle tower. The other Pelicans, ferrying Sergeant Johnson and his squad, would disable the final tower. ''Kilo 023'' deployed John-117, along with Stacker and his ODSTs, at a distance from the first tower after an Anti-Aircraft Wraith shot down the second Pelican carrying Marines and a Warthog. After John-117 defeated the War Chieftain, his entourage, and the Anti-Air Wraith, Commander Keyes' Pelican deployed a new Warthog and a Mongoose at the beachhead for the team. Meanwhile, the ''Shadow of Intent'' began a diversionary bombardment against the barrier, firing [[plasma torpedo]]es at the barrier shield.{{Ref/Reuse|cov}}
+Fighting through an infestation of the Brutes they had just killed and Johnson's Marines, the Elites and the Chief met up with Sergeant Stacker's Marines, supported by a Scorpion, a Gauss Warthog, and a Mongoose. The humans and Elites fought through the cliffs into the [[Citadel]] where the Halos could be activated was located. The Loyalists attempted to reinforce their troops by a large amount of Phantom transports gathered from around the installation, but the UNSC air forces countered this by attacking the Phantoms and their Banshee escorts with Hornets and Pelican Gunships. The ground forces managed to destroy the remaining Loyalist armor on the mountainside. Given another Gauss Warthog and air support from a flight of Hornets and a Pelican, the Marines destroyed Banshees,  Ghosts, a Prowler, plus a pair of Scarabs dropped in front of the Citadel by Brutes. After the destruction of the Scarabs, the Loyalists had lost their grip on the Citadel area. Without any heavy support, Spartan-117 and the Arbiter personally attacked the facility where Truth was to activate the Halo installations.[[Image:Scarab explodes.jpg|thumb|right|250px|The Loyalist ground forces are defeated]]
-While John-117 and his team traveled to the first tower, 'Vadam and Johnson, along with their teams, touched down at the second and third towers, respectively. Although John-117 and 'Vadam succeed in disabling two of the three towers, Johnson was ambushed by enemy reinforcements, and lost contact with the UNSC soon after. The Jiralhanae captured Johnson, and took him to the Citadel. The UNSC-Sangheili forces launched a second assault on the third tower, with John-117 escorting the dropships in an AV-14 Hornet. They first destroyed Covenant Banshees and a Phantom, securing air control outside the barrier. The third tower was heavily defended by a pair of AA Wraiths, Shades, another standard Wraith, and a huge group of Jiralhanae led by War Chieftain. Destroying the Brute defenders outside the third tower, John-117, Thel 'Vadam, and a team of five Sangheili proceeded inside, where they discovered the corpses of Johnson's team, except for Johnson. After the defending forces of Mgalekgolo, Yanme'e and Jiralhanae were eliminated, John-117 disabled the barrier tower, finally deactivating the barrier. The ''Shadow of Intent'' advanced towards the Citadel, but 'Vadum's attack was interrupted by the arrival of the Flood-infested ''High Charity'', which arrived via slipspace. ''High Charity'' launched debris that crippled the carrier and its weapons systems, forcing the ''Shadow of Intent'' to retreat. It also launched [[Flood dispersal pod]]s and began spreading Flood across the Ark. Keyes insisted that the Flood's arrival would only pressure Truth into activating the rings, and ordered the remaining ground forces to attack the Citadel.{{Ref/Reuse|cov}}
+[[Sergeant Major]] Johnson, who had disappeared during the assault, was in fact captured by Truth's forces and was being tortured into pressing the final switch to activate the other Halos. With Spartan-117 and the Arbiter too far away to stop High Prophet of Truth, Commander Keyes grabbed a Pelican dropship and crashed into the facility to rescue Johnson, but was killed soon after by Truth himself. However, her actions delayed Truth long enough for Spartan-117 and the Arbiter to stop him. The [[Gravemind]] dispatched Flood forces to assist Spartan-117 and the Arbiter in preventing the Halos' activation and the Arbiter personally killed Truth.  However, the Gravemind betrayed them and while Johnson managed to escape with Commander Keyes' body in the Pelican, Spartan-117 and the Arbiter had to fight their way outside.
+[[Image:230px-End_Truth.jpg|thumb|right|Arbiter killing the Prophet of Truth.]]
+Guilty Spark had managed to facilitate the making of a new Halo through the Ark, explaining that a tactical pulse from it would eliminate the Flood infestation.  However, this new Halo lacked an Activation Index.  The only way they could get another Index was to rescue Cortana from ''High Charity'' since she still possessed the Index from Installation 04.
-[[File:H3 CitadelBattle.jpg|300px|thumb|The massive final battle of the Human-Covenant War at the front of the Citadel.]]
+Johnson picked up the Arbiter and the Chief while Guilty Spark went off to the new Installation. The party then headed to the Shadow of Intent, where Johnson and the Ship Master rounded up the UNSC and Sanghelli forces. Meanwhile, the Arbiter and Master Chief headed towards High Charity in tow separate Banshees. Through a tough battle, [[Spartan-117]] and the Arbiter successfully entered the ruins of ''High Charity'' and recovered [[Cortana]], using a partly-damaged Pelican to escape while ''High Charity'' was destroyed as its reactors went critical after the they blasted them.
-During this time, the [[Jiralhanae Chieftain]] [[Hekabe]] decided to use the distraction from the Flood arrival to locate the ''[[vertex]]'' hidden on the Ark. The control device for the [[Sharquoi]], the ''vertex'' would allow Hekabe to control the creatures. Though the Prophets had some Sharquoi themselves, they had lacked the ''vertex'' and so could not control them and never unleashed them. Hekabe intended to use the ''vertex'' and the Sharquoi to gain power for himself and so fled the Ark with his loyalists before the battle ended despite fighting on the side of the Covenant.{{Ref/Reuse|envoy}}
+With the Index secure, the Arbiter ordered that the remaining UNSC forces relocate to the Separatist ships and escape back through the Slipspace portal to Earth while he, Spartan-117, and Sergeant Major Johnson moved in on the Control Room of the incomplete Halo. The ''Dawn'' was left behind for them to use to escape. By now what was left of the Gravemind had relocated to the new Halo. The three heroes with 343 Guilty Spark made it through waves of Flood to the Control Room. 343 Guilty Spark explained that the new Halo would be ready to fire within days, to which the group, particularly Johnson, protested. When Guilty Spark informed the three that activating Halo now would destroy both the Ark and the installation, Johnson told him to "deal with it" and prepared to activate the ring.
-Fighting through the Flood to exit the third tower, John-117 and the Sangheili regrouped with Gunnery Sergeant Stacker's Marines, now supported by a Scorpion, a Gauss Warthog, and a Mongoose. The humans and Sangheili fought through the cliffs to the area outside the Citadel, where the Covenant had set up lookout towers, Shade turrets, and ground vehicles. The Covenant attempted to reinforce their troops by a large amount of Banshees and Phantoms, but the UNSC air forces counterattacked with Hornets and Pelican gunships. The ground forces led by John-117 punched through the remaining Covenant armor on the mountainside. With the UNSC's arrival imminent, the Covenant deployed two final Scarabs, each commanded by a Jiralhanae War Chieftain, at the entrance to the Citadel, further supported by Prowlers, Ghosts, and Banshees. However, their efforts were in vain, and, with the Scarabs destroyed by John-117, any remaining Covenant stragglers were soon moped up by the UNSC.{{Ref/Reuse|cov}}
+Unwilling to let "his" ring be destroyed again, 343 Guilty Spark went rampant, killing Johnson and attacking Spartan-117 and the Arbiter. However, with the help of a dying Sergeant Johnson and his [[Spartan Laser]], Spartan-117 managed to destroy Guilty Spark and start the firing sequence of the new Halo. He and the Arbiter then took Johnson's Warthog and rushed towards the ''Dawn'' as the incomplete Halo powered up and started breaking apart. The two drove their way through hordes of battling Flood and [[Sentinel]] drones, with the world literally falling to pieces around them. The two heroes made it to the ''Dawn'', where the Arbiter was almost crushed by a Scorpion Tank due to the sudden acceleration of the ship. Agility and a pair of crates saved him. He made his way to the bridge of ''Dawn'' and took her into Slipspace just as the new Halo fired, with Master Chief almost being crushed by the same tank which descended through the cargo hold and into space. However, the Slipspace portal collapsed as the ''Dawn'' entered it and while the forward half with the Arbiter made it to Earth, the rear half fell out of Slipspace with Cortana and Spartan-117 floating into the dark abyss.
-While the Flood began climbing up the Citadel's far wall, John-117 and Thel 'Vadam led a small attack force, including N'tho 'Sraom, Usze 'Taham, as well as a few Marines and Sangheili, into the Citadel.{{Ref/Novel|Id=HitD252|HitD|Page=252}} Inside, the Prophet of Truth was giving a speech attempting to reassure his remaining followers, declaring that he was about to activate the Halo Array by forcing Johnson into interacting the control panel. Realizing that they had very little time left, John-117 and Thel 'Vadam hastily made their way to the elevator that would carry them to Truth's level, but the elevator's immense height meant that they would not be able to intervene in time.{{Ref/Reuse|cov}}
+With Truth dead, the Halos deactivated, and the Flood destroyed, the Battle of the Ark ended the Human-Covenant War.  A monument was erected in [[New Mombasa]] in remembrance of those who gave their lives in the war including Spartan-117 who is labeled [[MIA]].  The Arbiter and his brethren then departed Earth for [[Sanghelios]].
-Johnson attempted to goad the Chieftain that was holding him into killing him, but Truth, realizing this, stopped the Chieftain. With John-117 and the Arbiter too far away to stop Truth, Commander Keyes took her Pelican dropship and crashed it directly into the facility in an attempt to rescue Johnson, but she was killed by Truth himself when she hesitated to kill Johnson and herself to deny Truth a means to activate the rings. Johnson, struck by grief and shock, was easily made to activate the Array. However, Keyes' actions delayed Truth long enough for John-117 and the Arbiter to stop him. The Gravemind dispatched a swarm of [[Pod infector]]s and [[Flood combat form]]s, led by two [[Flood tank form]]s, to assist the UNSC-Sangheili force in preventing the Halos' activation. They were met by the Jiralhanae Chieftain and his Unggoy, Kig-Yar and Jiralhanae.{{Ref/Reuse|cov}}
-[[File:TruthDeath-large.jpg|thumb|left|300px|Arbiter killing the High Prophet of Truth.]]
-The defending Covenant forces quickly collapsed under the combined assault from the humans, Sangheili, and the Flood. With all Covenant in the Citadel eliminated, John-117 and 'Vadam reached the final room where they found Johnson cradling the dead body of Commander Miranda Keyes. 'Vadam confronted the Prophet of Truth, who was already partially infected by the Flood. 'Vadam allowed the Prophet to live long enough to see John-117 deactivate the rings, and 'Vadam personally killed Truth. With the Halo threat eliminated, the Gravemind betrayed the humans and the Sangheili, sending a large group of Flood combat forms and carrier forms after John-117 and Thel 'Vadam. The two attempted to escape on Keyes' Pelican, now piloted by Johnson, but they were knocked off by one of Gravemind's tentacles. With Johnson's Pelican spiraling out of the control, Johnson instructed the two to return to the elevator.{{Ref/Reuse|cov}}
-With the assistance of Aggressor Sentinels, the pair fought their way back to the elevator, which had been disabled. Without another choice, the two dropped down a small shaft in the room. At the bottom, John-117 followed flickers of Cortana to a control panel, and, upon its activation, they found [[Installation 08]] departing from the Ark's [[Foundry (location)|Foundry]]. Realizing this was Cortana's "solution" for the Flood, John-117 decided he needed to activate the ring at the Ark's isolated location, where the pulse would not destroy the sentient life in the [[Milky Way]] galaxy. 343 Guilty Spark concurred, that a tactical pulse would eliminate the Flood infestation on the Ark, and made his way to the ring to oversee the final preparations. However, this new Halo lacked an activation index. The only way they could get another index was to rescue Cortana from ''High Charity'', since she still possessed the index from the original Installation 04.{{Ref/Reuse|cov}}
-===Master Chief's raid on ''High Charity''===
-{{Main|Raid on High Charity}}
-While Johnson, 'Vadam, and 'Vadum rounded up the UNSC and Sangheili survivors from the battle, John-117 took a Banshee and [[Raid on High Charity|infiltrated]] the Flood-infested ''High Charity''. The Spartan fought through swarms of Flood and successfully recovered Cortana, who indeed still held the activation index from Installation 04. Under Cortana's guidance, John-117 sabotaged the city's reactors, causing a series of explosions that crippled the Gravemind and destroyed ''High Charity''. 'Vadam arrived shortly after, and the trio fled onboard a crashed Pelican.{{Ref/Level|Id=cortana|H3|[[Cortana (level)|Cortana]]}}

-===Finishing the fight===

-With the index secured, Thel 'Vadam ordered Rtas 'Vadum to take the human and Sangheili survivors to leave the Ark, using the slipspace portal to Earth. 'Vadam accompanied John-117 and Cortana to the incomplete Halo. Sergeant Major Johnson piloted the UNSC ''Forward Unto Dawn'', which was left behind for their escape, to a safe location near the control room, then drove a Warthog to the control room. The Gravemind, meanwhile, had begun to rebuild itself on the new ring, and sent [[Flood dispersal pod]]s to stop the three interlopers. John-117, 'Vadam, and Johnson, with the assistance of local Sentinels, fought through the Flood and entered the Control Room. Inside, Spark explained that the new Halo would be ready to fire within days, to which the group, particularly Johnson, protested. When Guilty Spark informed the three that activating Halo now would destroy both the Ark and the installation, Johnson told him to "deal with it" and prepared to activate the ring.{{Ref/Reuse|halo}}
-Unwilling to let "his" ring be destroyed again, 343 Guilty Spark attacked the trio. He mortally wounded Johnson, took down the Master Chief's shields, and blew 'Vadam out of the room. Spark cornered John-117, but with the help of Johnson and his [[M6 Spartan Laser|Spartan Laser]], John-117 defeated Guilty Spark and initiated the firing sequence of the new Halo. The incomplete Halo began ripping itself apart under the charging sequence. Fighting past the Flood and the Sentinels that have turned on them, John-117 and 'Vadam took Johnson's Warthog and rushed towards the ''Dawn'' as the incomplete Halo powered up and started breaking apart. The two drove their way through hordes of battling Flood and Sentinels. The two made it onto the ''Dawn''{{'}}s hangar bay, from where 'Vadam ran to the bridge while John-117 inserted Cortana into a holotank in the hangar bay, so she could activate the ''Dawn''{{'}}s engines. The ''Dawn'' left the ring just as it fired.{{Ref/Level|Id=halo|H3|[[Halo (Halo 3 level)|Halo]]}} The firing sequence shook the ring into pieces and heavily damaged Installation 00. The Slipspace portal collapsed as the ''Dawn'' entered it, and while the forward half with 'Vadam made it to Earth, the rear half fell out of Slipspace at an unknown location, leaving John-117 and Cortana stranded in space.{{Ref/Reuse|epi}}
 ==Aftermath==
-===The Flood===
-[[File:H3 - I08 Detonates.png|300px|thumb|Installation 08 fires above the Ark, severely damaging everything on its surface.]]
-On December 14, 2552, just three days after the battle and the ring's activation, 000 Tragic Solitude marshalled his Sentinels to construct a [[containment shield]] around the remains of ''High Charity's'' ruins, in fear that any few surviving Flood remnants would escape the crash site. Furthermore, he instructed his Sentinels to raze a perimeter, and the local [[refugia]] modified to ensure no nearby [[Sentience|sentient]] life survived, thus depriving the Flood of any host bodies in close proximity.{{Ref/Game|Id=idle hands ii|HW2|Phoenix Log#The Archive 2|Phoenix Log – "Idle Hands II"}} By [[2553#February|February 19, 2553]], the Flood remnants were contained within the rubble of ''High Charity'',{{Ref/Game|Id=uncomfortable i|HW2|Phoenix Log#Manifestation 2|Phoenix Log – "An Uncomfortable Truth I"}} with a [[battalion]] of Sentinels patrolling in the vicinity of the shield to prevent both the Flood from escaping and future "invaders" from releasing them.{{Ref/Reuse|idle hands ii}}
-However, their defenses were proven to be ineffective, with [[Banished]] forces, led by Jiralhanae [[Voridus]], [[Outbreak on Installation 00|releasing the Flood]] from the ruins of ''High Charity'' and providing them with hosts to infect during the [[Second Ark Conflict]] on [[2559#June|June 4, 2559]].{{Ref/Reuse|wrong}} This inadvertently caused a Flood outbreak onto the installation, leading to a desperate struggle between the Banished and the parasite. Ultimately, the Banished managed to destroy a [[Proto-Gravemind]] that was moments away from becoming a Gravemind and the Ark's Sentinels and the Banished managed to once again contain the Flood.{{Ref/Level|HW2|Manifestation}}
-===The Covenant===
-{{Main|Dhas Bhasvod's Covenant|Covenant remnants}}
-Despite the death of Truth and the vast majority of his forces, as well as the ravaging of the Ark, a [[Dhas Bhasvod's Covenant|small sliver of the Jiralhanae loyalist forces]] remained inside the ''Anodyne Spirit'' which shielded them for the firing of [[Installation 08]]. The survivors guarded it for years using stocked supplies as well as Covenant-issued equipment{{Ref/Reuse|Id=Sacrifice}} and had access to numerous Covenant vehicles.{{Ref/Reuse|divinechapt2}}
-Although the Battle of Installation 00 marked the end of the Human-Covenant War, numerous new [[Covenant remnants|splinter factions from the Covenant]] were created in its wake. These factions ranged from pragmatic mercenaries to fanatical religious cultists.{{Ref/Comic|Halo: Escalation|Issue=[[Halo: Escalation Issue 5|5]]}} These factions would come into [[Post-Covenant War conflicts|conflict with each other]], with notable conflicts like [[Sangheili-Jiralhanae war|a war between the Sangheili and the Jiralhanae]] following the Great Schism, and [[Blooding Years|numerous civil conflicts]] fought between the Swords of Sanghelios and various other Sangheili factions.{{Ref/Site|URL=https://www.halowaypoint.com/en-us/universe/locations/sanghelios|Site=Halo Waypoint|Page=Universe - Locations - Sanghelios|D=20|M=10|Y=2021}}

-{{Main|Battle of Requiem}}
-The Portal between Installation 00 and Earth collapsed while {{UNSCShip|Forward Unto Dawn}} was still inside it. As a result, the ship was cut in half; the front arriving at Earth and the back half being lost in space. Thel 'Vadam, sitting on the bridge at the time, was part of the front half but, without any engines, soon crashed into the ocean, from where he was rescued by UNSC forces on Earth. John-117 and Cortana were in the rear half, and though they survived the Portal’s collapse, they were stranded in space and declared MIA. John-117 went into cryo-sleep while Cortana activated a [[distress beacon]] indicating their status.{{Ref/Reuse|epi}} After drifting in an unknown region of space for over four years until [[2557#July|2557]],{{Ref/Level|H4|[[Dawn (level)|Dawn]]}} the rear half of the ''Dawn'' was caught in the [[gravity well]] of a Forerunner [[shield world]] known as [[Requiem]],{{Ref/Level|Id=H4|H4|[[Requiem (level)|Requiem]]}} where they would come into [[Battle of Requiem|conflict]] with [[Jul 'Mdama's Covenant]].{{Ref/Reuse|H4}}

With the exception of Thel 'Vadam, the Sangheili were not present at the dedication service, instead remaining aboard ''Shadow of Intent''. After the ceremony, Lord Hood, despite being unable to forgive the Sangheili for what they did to humanity at the beginning of the war, shook 'Vadam's hand and thanked him for standing beside the Master Chief at the Ark. The Arbiter then joined [[Rtas 'Vadum]] on the bridge of ''Shadow of Intent'', both agreeing to return to [[Sanghelios]] to ensure its safety.

+===Installation 00 and the Flood===
+It is assumed that the firing of the Halo ring either severely damaged or destroyed the Ark while killing the Flood forces around Installation 00, including the Gravemind commanding the massing Flood amid the battle.

+===''Forward Unto Dawn''===
-<gallery>
+The Portal between [[Installation 00]] and Earth collapsed while ''[[Forward Unto Dawn]]'' was still inside it.  As a result, the ship was cut in half the front arriving at Earth and the back half being lost in space. The Arbiter, sitting on the bridge at the time, was part of the front half but, without any engines, soon crashed. However, Spartan-117 and Cortana were in the rear half and were missing.

-==List of appearances==
+It is known that Cortana and [[Spartan-117]] survived the Portal's collapse.  Spartan-117 went into cryo-tube while Cortana sent out a signal indicating their status.  It is unknown if their message was ever received or if they were rescued. The amount of time that passed in the interim is unknown, and it is also unknown if Cortana succumbed to [[AI]] [[Rampancy]] or even survived the course of the journey, as UNSC [[Smart AI]] minds become too interlinked and "think themselves to death" after approximately seven years of operational service.

-==Notes==
+===Legacy===
-{{Ref/Notes}}
+A monument was made near the town of Voi where the Forerunner artifact had been built.  It reads "''In memory of those fallen in the defense of Earth and her Colonies. [[March 3, 2553]].''" On it were the pictures of the most outstanding UNSC personnel who went through the Portal but did not return.  Spartan-117 is honored on it by a "117" scratched onto the monument and a [[Master Chief Petty Officer]] badge taped on the monument.
