This '''Installation 07 conflict''', colloquially referred to as a '''war''',{{Ref/Quest|HI|Graveyards|[[Pelican Down (Halo Infinite level)|Pelican Down]]|Quote=When you're done with this war, we'll get away from here. Far away.|Quotee=[[Fernando Esparza]]}} was a large multi-faction [[battle]] that took place starting on [[2559#December|December 12, 2559]], prominently between the [[United Nations Space Command]] and the [[Banished]] on the [[Forerunner]] [[Halo Array|Halo]] [[Installation 07]], otherwise known as "Zeta Halo", and continues as of [[2560#May|May 31, 2560]].{{Ref/Reuse|Premiere}} The earlier stages of battle ultimately led to the fall of [[Cortana]] and her [[Created]] while simultaneously severely damaging Installation 07, making the conflict the final overarching battle of the larger [[Created conflict]] and the last stand of the Created,{{Ref/Reuse|saatriox}} although remaining lingering affiliates continued to exist as of [[2560]].{{Ref/Site|Id=cflegendend|URL=https://www.halowaypoint.com/news/canon-fodder-legendary-endings|SiteName=Halo Waypoint|PageName=Canon Fodder - Legendary Endings|D=19|M=12|Y=2021}}  

[[File:HINF Silent Auditorium building.png|250px|thumb|right|The [[Silent Auditorium (location)|Silent Auditorium]] was where the Xalanyn was judged by the Forerunners to be imprisoned on Installation 07.]]

In [[2558#October|October 2558]], when the [[Created conflict]] began with the rogue [[AI]] [[Cortana]] [[The Reclamation|subjugating]] major planets and governments across the galaxy with her Guardians, the [[UNSC Armed Forces]] were broken with the {{UNSCShip|Infinity}} forced into hiding.{{Ref/Level|Id=h5|H5|Guardians}} Cortana ushered in a new era with her [[Created]] as rulers, enforcing martial law across their territory. The ''Infinity'' conducted operations against the Created in limited capacity.{{fact}}

[[File:H5G-Infinity&Guardian.jpg|250px|thumb|left|The entirety of the [[UNSC Armed Forces]] were fractured by the [[Guardian Custode|Guardians]] as part of the [[Created]]'s [[The Reclamation|rise]].]]  

Cortana made a general broadcast, inviting numerous species and factions to submit themselves to the guardianship of the Created,{{Ref/Reuse|h5}} but threatened those who would resist her leadership with violence.{{Ref/Anthology|Halo: Fractures|[[What Remains]]}} Personally confronted by Cortana, the [[Jiralhanae]] [[Atriox]], the [[Warmaster|leader]] of a group of mercenary raiders known as the [[Banished]], declared his independence from Cortana, and thus, opposition against the Created. In a show of force for Atriox's defiance, Cortana commanded her Guardians to destroy the Jiralhanae homeworld [[Doisac]] while communicating with Atriox.{{Ref/Quest|HINF|Reckoning|Repository (Halo Infinite)|Repository}} Seeking to fight back against Cortana and access the ring's secrets, Atriox led his Banished forces to [[Installation 07]], where the Created leader resided.

Doctor [[Catherine Halsey]] devised a plan to stop Cortana. She created an artificial intelligence known as "[[The Weapon]]", created from a cloned brain of herself. The copy would lock Cortana down, preventing her from controlling her vast Guardian and [[Promethean]] forces and isolating her in her current location, [[Installation 07]].{{fact}} A plan was formed, with the initial intent to send [[Blue Team]] to the surface to retrieve Cortana, though this was later revised to be just John-117 and The Weapon, accompanied by the ship's [[SPARTAN-IV program|Spartan]] and [[Orbital Drop Shock Troopers|ODST]] complement.{{Ref/Game|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #02 - Captain's Report}} Halsey had plans for [[Frederic-104]], [[Kelly-087]], and [[Linda-058]], but they were reassigned by [[Captain (NAVCOM)|Captain]] [[Thomas Lasky]] to another mission unknown to Halsey, much to her chagrin.{{Ref/Game|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #03 - Duty Clearance}} [[John-117]] was to travel to the surface of the ring and deploy the Weapon to lock down Cortana, then return her to the ''Infinity'' for deletion.{{Ref/Game|HI|Audio log (Halo Infinite)#Recovered Files 2|UNSC Audio log|Detail=Recovered Files #04 - The Weapon}}

On [[2559#December|December 12, 2559]], {{UNSCShip|Infinity}} and her escort fleet, composed of six {{Class|Mulsanne|frigate}}s, arrived at Installation 07.{{Ref/Game|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #01 - Preparations}} Upon arrival, the UNSC fleet was ambushed by four [[Banished dreadnought]]s.{{Ref/Game|Id=ia4|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #04 - Arrival}} Warmaster Atriox personally led Banished raiding parties aboard the ''Infinity'',{{Ref/Reuse|ia4}} all the while sending occupation forces to the Ring's surface by the hundreds.{{Ref/Game|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #07 - Objectives}} Despite the UNSC repelling the boarders, the ''Infinity''{{'}}s main engine were taken offline within minutes after the initial attack, and Captain Lasky ordered the deployment of [[the Weapon]].{{Ref/Game|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #05 - Zero Hour}} Under the overwhelming assault, Lasky ordered all hands aboard the UNSC ''Infinity'' to abandon ship.{{Ref/Reuse|e1}}  

John-117 ordered Spartan [[Hudson Griffin]] and Fireteam Taurus to take Lasky to a dropship while he held off the boarders at the hangar bay.{{Ref/Game|HI|Audio log (Halo Infinite)#Infinity's Approach 2|UNSC Audio log|Detail=Infinity's Approach #10 - Priorities}} However, despite his efforts, the hangar bay would eventually be lost to the Banished. As one dreadnought rammed the dorsal hull of the ''Infinity'', causing massive structural damage, Atriox fought John-117 in the hangar bay and defeated the Spartan. The limp Spartan was thrown from the the hangar bay and into space.{{Ref/Quest|Id=wg|HI|Ringfall|Warship Gbraakon}}{{Ref/Mag|Id=GI341|Game Informer|341|page 43}}

After Lasky’s lifeboat was away, Spartan Griffin ordered the evacuation of the remaining [[SPARTAN-IV program|Spartan-IVs]].{{Ref/Reuse|e1}} Spartan-IVs, marines, and crew fled onboard drop pods,{{Ref/Game|HI|Audio log (Halo Infinite)#Evacuation 2|UNSC Audio log|Detail=Evacuation #07 - Intrepid Descent}} Pelicans,{{Ref/Game|HI|Audio log (Halo Infinite)#Ringfall 2|UNSC Audio log|Detail=Ringfall #01 - Enemy Territory}} and lifeboats to the surface of Installation 07,{{Ref/Game|HI|Audio log (Halo Infinite)#Ringfall 2|UNSC Audio log|Detail=Ringfall #02 - The Calm Before}} many being shot down seconds after exiting the vessel.{{Ref/Game|Id=e3|HI|Audio log (Halo Infinite)#Evacuation 2|UNSC Audio log|Detail=evacuation #03 - Touchdown}} Some were escorted by members of [[Fireteam Windfall]] onboard fighters.{{Ref/Game|HI|Audio log (Halo Infinite)#Evacuation 2|UNSC Audio log|Detail=evacuation #06 - Buying Time}} Fireteam Taurus made landfall in an area south of the Silent Auditorium,{{Ref/Game|Id=r4|HI|Audio log (Halo Infinite)#Ringfall 2|UNSC Audio log|Detail=Ringfall #04 - Run and Guns}} where they fought through Banished patrols to disable a trio of [[Gorespike cannon]]s firing at the UNSC crafts landing on the ring.{{Ref/Game|HI|Audio log (Halo Infinite)#Evacuation 2|Spartan Audio log|Detail=Evacuation #05 - Overwatch}} They succeed in disabling two cannons before a cataclysmic event on the ring disabled the third cannon.{{Ref/Reuse|r4}}

In the end, the outcome of the space battle saw at least two ''Mulsanne''-class frigates, including the {{UNSCShip|Mortal Reverie}},{{Ref/Game|Id=hafh|HI|Audio log (Halo Infinite)#Reverie 2|Spartan Audio log|Detail=Reverie #01 - Home Away From Home}} crashing on the fragmented section of the ring.{{Ref/Quest|Id=pdown|HI|Graveyards|[[Pelican Down (Halo Infinite level)|Pelican Down]]}} Although the status of the UNSC ''Infinity'' is unknown aside from having suffered heavy damage from Banished vessels,{{Ref/Reuse|wg}} she may have broke apart and crash landed on the ring.{{Ref/YouTube|Id=GameInformer|fSNXqbbAjC4|Game Informer|Halo Infinite Impressions: Exploration, Upgrades, and More|Time=9:17}}{{Ref/Site|Id=GIInf|URL=https://www.gameinformer.com/2021/11/11/off-the-golden-path-progression-and-exploration-in-halo-infinite|Site=Game Informer|Page=Off The Golden Path – Progression And Exploration In Halo Infinite|D=11|M=11|Y=2021|Quote=[...] while rallying the UNSC forces that have crash-landed there after the devastating destruction crash of the UNSC Infinity.}}{{Ref/NoteReuse|infinity}}

===Explosion on the Ring and Created's destruction===

[[File:HINF Zeta Halo Destroyed.png|right|thumb|250px|The fragmented Installation 07 following Cortana's sacrifice to temporarily break the ring, rendering the ring inoperable for the Banished.]]

{{Quote|Look around, Cortana. Your [[Created|empire]]. Over! Your great plan? Ended at the hands of [[human|those]] who made you.|[[Warmaster]] [[Atriox]] to Cortana as he presented her with the terms of her surrender following [[Created]]'s defeat.{{Ref/Reuse|saatriox}}}}

As UNSC forces scattered over the ring and fought against the Banished forces, Atriox confronted Cortana at the [[Silent Auditorium (location)|Silent Auditorium]], claiming he had killed John-117 and Cortana's Created empire was over, leaving the latter devastated by the news of John-117's apparent death. Seemingly locked down by the Weapon deployed from {{UNSCShip|Infinity}}, Cortana could not retaliate.{{Ref/Quest|Id=saatriox|HI|Endless|Silent Auditorium|Quote=Look around, Cortana. Your Empire. Over! Your great plan? Ended at the hands of those who made you.|Quotee=Atriox}} Atriox presented her with the terms of her surrender, intending to take control of the ring and access the secrets locked within the Silent Auditorium.{{Ref/Quest|HI|Endless|Silent Auditorium|Quote=I have learned so much, Cortana. this Ring is different. It has secrets within... That I will have. This... Silent Auditorium. Do you know its history? Its true purpose? I have little needs for a failed god. This Ring is all I need. Surrender it to me.|Quotee=Atriox}} In an attempt to prevent Atriox from accessing Silent Auditorium or possibly activating the ring, Cortana detonated an explosion from the Auditorium, fracturing the ring's surface and leaving it inoperable.{{Ref/Quest|Id=sa|HI|Endless|Silent Auditorium|Quote=It was her. She destroyed the Ring. Stopped my deletion.|Quotee=The Weapon}} Her efforts were proven to be temporary, as the ring soon begun its self-repair process,{{Ref/Game|HI|Audio log (Halo Infinite)#Reverie 2|UNSC Audio log|Detail=Reverie #04 - On the Mend}} though it would take months to complete.{{Ref/Quest|Id=spire|HI|Connections|Spire (Halo Infinite level)|Spire}} Although he survived the explosion, Atriox was left severely scarred,{{Ref/Reuse|stinger}} and was also presumed dead by both the UNSC and the Banished.{{Ref/Reuse|wg}} Cortana, in hopes of John-117's survival, predicted he would stop the Banished from accessing the Silent Auditorium and prevented the Weapon's deletion protocol so she could assist him,{{Ref/Reuse|sa}} leaving the Weapon in the ring's subterranean structure for retrieval.{{Ref/Quest|Id=foundation|HI|Ringfall|Foundation (Halo Infinite)|Foundation (Halo Infinite)}} At some point during the Installation 07 conflict, at least one [[Guardian Custode]] was present over Installation 07 and subsequently crashed on the ring by [[2560]].{{Ref/Reuse|guardian}}

During the destruction event, Installation 07, along with the debris from the space battle, was transported away from the the Ephsu system to an unknown location.{{Ref/Game|Id=oi9|HI|Audio log (Halo Infinite)#Outpost Intel 3|UNSC Audio log|Detail=Outpost Intel #09 - To Andrew Valleros}} The explosion also affected the ground battle between the UNSC and the Banished. The ring's fragmentation scattered UNSC ground forces,{{Ref/Game|HI|Audio log (Halo Infinite)#Ringfall 2|UNSC Audio log|Detail=Ringfall #07 - Alone}} but disabled [[Gorespike cannon|Banished anti-air cannons]], allowing more UNSC aircrafts to land on the ring.{{Ref/Reuse|r4}}

Despite the explosion, the Banished occupied the ring, with some UNSC forces gathering on one of the fragments. They would form a resistance which included three [[Spartan]]s.{{Ref/Site|Id=parallel|URL=https://www.halowaypoint.com/en-us/news/parallel-threads|Site=Halo Waypoint|Page=Canon Fodder - Parallel Threads|D=25|M=6|Y=2021}} The Banished committed a large force at the eastern fragmented sections of the ring.{{Ref/Quest|HI|Reformation|FOB November}} On one of the fragments to the west, a large group of survivors led by Spartan [[Hudson Griffin]] established a base of operations in the wreckage of the ''Mulsanne''-class frigate {{UNSCShip|Mortal Reverie}}, discovered by Spartan [[Vedrana Makovich]].{{Ref/Reuse|hafh}} Under the leadership of Spartan Griffin, the UNSC forces at the ''Reverie'' conducted guerilla ops against the Banished forces.{{Ref/Game|Id=oi13|HI|Audio log (Halo Infinite)#Outpost Intel 3|UNSC Audio log|Detail=Outpost Intel #13 - Trench Warfare}} [[First Lieutenant]] [[Floyd (Installation 07)|Floyd]] conducted multiple field surveys and reconnaissance missions on nearby Banished outposts, reporting his findings to Spartans Griffin, [[Bertold Vettel]], and [[Bonita Stone]],{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|UNSC Audio log|Detail=Outpost Intel #02 - No Entry}}{{Ref/Game|Id=mem|HI|Audio log (Halo Infinite)#Outpost Intel 3|UNSC Audio log|Detail=Outpost Intel #10 - Making Ends Meet}} while also attempting to contact other UNSC forces.{{Ref/Reuse|oi13}} The UNSC also set up multiple [[Forward Operating Base]]s in the regions on the fragmented section of the ring.{{Ref/Reuse|s1}}

On [[2560#January|January 20, 2560]], Kovan conducted a recon sweep deep inside Banished-occupied territory. She observed that Banished forces were only unified under Escharum, with internal competition among its members. She reported her findings to Griffin, and suggested that an attempt on Banished [[War Chief]] [[Escharum]]'s life may fragment the Banished leadership. Griffin decided their best course of action was to assassinate the War Chief.{{Ref/Game|Id=r6w|HI|Audio log (Halo Infinite)#Reverie 2|Spartan Audio log|Detail=Reverie #06 - Weakness}} A four-Spartan team, the members of which were decided by drawing straws, was to infiltrate Banished territory and assassinate Escharum, while other Spartans remained at the ''Reverie'' to defend the base. In the end, on January 23, 2560, Spartan Griffin led Spartans [[Panago]], [[Henri Malik|Malik]], and [[Sarkar]] in an assassination mission on Escharum. Griffin left [[Bertold Vettel]] in charge of the UNSC forces at ''Reverie''.{{Ref/Game|Id=tlb|HI|Audio log (Halo Infinite)#Retaliation 2|Spartan Audio log|Detail=Retaliation #02 - Those Left Behind}} However, Escharum anticipated Griffin's actions. His forces ambushed the Spartan team, killing the other three and leaving Griffin badly wounded. Escharum taunted Griffin, letting him know that he'd sent most of his forces to assault the ''Reverie''. Griffin managed to send an encrypted message to warn ''Reverie'' before Escharum captured and handed him over to [[Chak 'Lok]] for torture.{{Ref/Game|Id=r3c|HI|Audio log (Halo Infinite)#Retaliation 2|Spartan Audio log|Detail=Retaliation #03 - Confrontation}} Under the combined leadership of Vettel and counsel of Makovich, the UNSC forces at the ''Reverie'' braced for the Banished's attack.{{Ref/Game|Id=dtl|HI|Audio log (Halo Infinite)#Retaliation 2|Spartan Audio log|Detail=Retaliation #06 - Drawing the Line}}

On January 31, 2560,{{Ref/Game|Id=rt|HI|Audio log (Halo Infinite)#Retaliation 2|Spartan Audio log|Detail=Retaliation #07 - Red Tide}} [[Jiralhanae Chieftain|Chieftain]] [[Tremonius]] and [[Jiralhanae Captain|Captain]] [[Arthoc]] led a massive Banished force from [[Riven Gate (location)|Riven Gate]] on an assault against the ''Reverie''.{{Ref/Reuse|rt}}{{Ref/Game|Id=iyh|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #15 - In Your Honor}} Under an overwhelming assault, the UNSC forces retreated from the crash site on [[2560#February|February 2]].{{Ref/Game|Id=r8tr|HI|Audio log (Halo Infinite)#Retaliation 2|Spartan Audio log|Detail=Retaliation #08 - The Retreat}} Following the battle, the crash site surrounding the ship was converted into [[Outpost Tremonius (location)|a Banished outpost]]. As a reward for Tremonius' victory, Escharum had the outpost named after Tremonius,{{Ref/Reuse|iyh}} who would be promoted to the rank of [[Jiralhanae Warlord|Warlord]].{{Ref/Game|HI|[[Ascension (achievement)|Ascension]] achievement requirement|Quote=Defeated the Banished warlord Tremonius.}}

[[File:HINF MarineAmbushConcept.jpg|right|250px|thumb|Hunted down by the Banished, UNSC remnants were unable to take any major offensives and forced to conduct mostly defensive tactics.]]

The surviving UNSC personnel were forced to conduct mostly defensive tactics over the next few months, losing their last Forward Operating Base by [[2560#March|March 3]].{{Ref/Game|Id=s1|HI|Audio log (Halo Infinite)#Scattered 2|Spartan Audio log|Detail=Scattered #01 - Rubicon Protocol}} Meanwhile, the Banished began setting up more infrastructure on the ring. They built sensory arrays at the [[Horn of Abolition (location)|Horn of Abolition]] and hijacked a Forerunner resonance amplifier to boost their relays,{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #03 - A Boon}} thus always staying one step ahead of the UNSC forces.{{Ref/Game|Id=tal|HI|Audio log (Halo Infinite)#Outpost Intel 3|UNSC Audio log|Detail=Outpost Intel #04 - They are Listening}} They also established [[Annex Ridge (location)|Annex Ridge]], where they conducted research on the ring's artifacts.{{Ref/Game|Id=ahap|HI|Audio log (Halo Infinite)#Outpost Intel 3|UNSC Audio log|Detail=Outpost Intel #11 - A Hastily-Assembled Plan}} Escharum ordered his Banished forces to capture UNSC survivors,{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #07 - That Which Remain}} who would be processed at [[Redoubt of Sundering (location)|Redoubt of Sundering]] before being taken to [[Chak 'Lok]]'s [[Tower]] for interrogation under torture and duress,{{Ref/Quest|HINF|Connections|Redoubt of Sundering|Quote=This must be where they processed prisoners before sending them to the Tower.|Quotee=The Weapon}} and then finally to Escharum's base, [[House of Reckoning (location)|House of Reckoning]].{{Ref/Reuse|tower}} The UNSC forces were unable to stage any major offensives due to the loss of an organized leadership, but what Spartans remained enacted the [[Rubicon Protocol]]: doing all they could to prevent the Banished from taking control of the ring and protect [[Earth]].{{Ref/Reuse|s1}} In one particular incident, Spartans [[M. Jaide]] and [[Rosado]] managed to hijack a [[siege-hauler]] carrying artifacts from Annex Ridge.{{Ref/Reuse|ahap}}

With little UNSC resistance, the Banished shifted their attention to excavations, salvaging UNSC hardware to aid their excavation efforts,{{Ref/Reuse|mem}}{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #09 - Unnatural Defenses}} while meeting resistance from the ring's self-repair process.{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #11 - Slow and Steady}} By [[2560#April|April 23]], the Banished has found numerous [[cylix]]es buried in the ring.{{Ref/Game|Id=wlb|HI|Audio log (Halo Infinite)#Scattered 2|Spartan Audio log|Detail=Scattered #02 - What Lies Beneath}} Tremonius found one such cylix, which contained the [[Xalanyn]] known as "[[the Harbinger]]".{{Ref/Game|HI|Audio log (Halo Infinite)#Escharum's Testimony 2|Banished Audio log|Detail=Escharum's Testimony #02 - Cylix}} Under the supervision of Escharum, the Banished forced a human [[prisoner of war]], [[Lucas Browning]], to interface with the Harbinger's cylix, releasing her from stasis.{{Ref/Game|HI|Audio log (Halo Infinite)#The Prisoner 2|UNSC Audio log|Detail=The Prisoner #02 - What was Inside}}{{Ref/Game|HI|Audio log (Halo Infinite)#The Prisoner 2|UNSC Audio log|Detail=The Prisoner #03 - She was Smiling}}  

After her release, the Harbinger told Escharum of the [[Reformation]],{{Ref/Game|Id=et5|HI|Audio log (Halo Infinite)#Escharum's Testimony 2|Banished Audio log|Detail=Escharum's Testimony #05 - Reformation}} which expedites the ring's self-repair process by creating materials for repairs.{{Ref/Reuse|spire}} The process would return the ring to an operational status for Escharum,{{Ref/Reuse|et5}} who hopes to achieve Atriox's goal of controlling the ring and claim the ring as their new home.{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #10 - The Dream of Atriox}} However, unbeknownst to Escharum,{{Ref/Reuse|et5}} the Harbinger seeks to rebuild the Silent Auditorium,{{Ref/Game|HI|Audio log (Halo Infinite)#Escharum's Testimony 2|Banished Audio log|Detail=Escharum's Testimony #07 - Loyalties}} which was destroyed when Cortana detonated the ring, and locate her fellow Xalanyn. Despite Escharum being distrustful towards the Harbinger,{{Ref/Game|HI|Audio log (Halo Infinite)#Escharum's Testimony 2|Banished Audio log|Detail=Escharum's Testimony #03 - Harbinger}} the two formed an uneasy alliance, bolstering the Banished forces with the Harbinger's [[Skimmer]]s.{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #05 - Re: Damnable Eyes}}  

The Harbinger aided in the excavation efforts, personally inspecting excavation sites and modifying the Banished's mining equipment to cut through Forerunner alloys.{{Ref/Game|HI|Audio log (Halo Infinite)#Outpost Intel 3|Banished Audio log|Detail=Outpost Intel #06 - Secrets Below}}{{Ref/Quest|Id=excavation site|HI|Connections|Excavation Site}} Furthermore, upon the discovery of the [[Conservatory (location)|Conservatory]], where the monitor of the installation, [[117649 Despondent Pyre]], resided, they prioritized on excavating the facility.{{Ref/Reuse|wlb}} The Harbinger aimed to acquire the monitor's "encephalon", which would allow her to initiate the Reformation. Having observed the excavation site, Spartans Makovich and [[Theodore Sorel]] correctly deduced that Escharum was searching for the Monitor, and spent the next few weeks stalling the Banished's excavation efforts.{{Ref/Game|Id=tp|HI|Audio log (Halo Infinite)#Scattered 2|Spartan Audio log|Detail=Scattered #04 - The Prize}} Despite the Spartans' sabotage, the Banished's excavation eventually completed on May 15. Makovich and Sorel followed the Banished into the underground facility,{{Ref/Game|Id=s7i|HI|Audio log (Halo Infinite)#Scattered 2|Spartan Audio log|Detail=Scattered #07 - Infiltration}} only to be ambushed and killed by members of the [[Hand of Atriox]].{{Ref/Game|Id=s8|HI|Audio log (Halo Infinite)#Scattered 2|Spartan Audio log|Detail=Scattered #08 - The Assassin}}{{Ref/Game|Id=s9|HI|Audio log (Halo Infinite)#Scattered 2|Spartan Audio log|Detail=Scattered #09 - Killers}} However, the Harbinger and the Banished would not find 117649 Despondent Pyre inside the Conservatory until May 28.{{Ref/Quest|Id=conservatory|HI|Connections|Conservatory}}

[[File:HINF FoundHope.png|thumb|left|250px|After being lost for over six months, John-117 was eventually found by a [[Fernando Esparza|civilian engineer]], turning the tide of the war on Installation 07.]]

On May 28,{{Ref/Reuse|Premiere}} civilian engineer Fernando Esparza, onboard the Pelican ''Echo 216'' he had stolen from ''Infinity'' six months prior, found John-117 drifting in space around Installation 07. The Spartan's armor had activated survival mode to keep the Spartan alive. After bringing him aboard and reactivating the armor via a power transfer, John-117 was awakened. ''Echo 216'' was quickly discovered by the Banished dreadnought ''[[Ghost of Gbraakon]]'', which activated its stasis beam to pull the Pelican onboard. John-117 left the Pelican and boarded the ''Gbraakon'', destroying the ship to prevent the Pelican from being captured. Escharum was made aware of the Spartan's survival, and reacted with excitement.{{Ref/Reuse|wg}}  

Escharum ordered Chak 'Lok to lure the Master Chief to the Tower using Griffin's distress signal. At the Weapon's advice, John-117 pursued the signal to the Tower, where he confronted and killed 'Lok. Despite being freed from the torture device, Griffin succumbed to his wounds, but told John-117 of the Conservatory.{{Ref/Quest|Id=tower|HI|Lockdown|The Tower}} John-117 and the Weapon then traveled to the excavation site, where the Spartan defeated [[Bassus]], and entered the Conservatory.{{Ref/Reuse|excavation site}} Inside the Conservatory, they watched 117649 Despondent Pyre being captured by Skimmers. Pyre was tortured and interrogated by the Harbinger, who retrieved the monitor's encephalon.{{Ref/Reuse|conservatory}} With Pyre seemingly destroyed, submonitor [[Adjutant Resolution]] was activated.{{Ref/Reuse|spire}} The Harbinger left for the surface, with John-117 in pursuit. At the entrance of the Conservatory, John-117 confronted the Harbinger, but was unable to prevent her from activating the Reformation using Pyre's encephalon.{{Ref/Reuse|conservatory}} 43 Reformation Spires, including one Command Spire, began appearing at various locations on the ring,{{Ref/Reuse|pdown}} awaiting an initiation sequence.{{Ref/Reuse|spire}} The Harbinger escaped, with the Spartan heading to the Reformation Spire that materialized outside the Conservatory.{{Ref/Reuse|conservatory}}

However, while en route to the Command Spire, ''Echo 216'' crash landed on the ring after taking fire from three [[Gorespike cannon]]s. John-117 proceeded to the three cannons, eliminating the Banished defenses and destroying each cannon with the help of the Weapon. Escharum ordered the deployment of [[Hand of Atriox]], with [[Tovarus]] and [[Hyperius]] attempting an intercept on John-117. They failed to deter the Spartan's progress, being killed by John-117. The Harbinger, anticipating the Chief's intent to shut down the Reformation, had Escharum set up defenses at the Command Spire,{{Ref/Reuse|pdown}} while she modified the data sequence for accessing the Spire.{{Ref/Reuse|sequence}} Intending to challenge the Master Chief in a duel, Escharum ordered [[Jega 'Rdomnai]] to capture the Spartan.{{Ref/Reuse|pdown}}

With the Harbinger modifying the sequence, John-117 and the Weapon arrived at the Command Spire to find its entrance under lockdown. They fought through Banished defenses to access four Forerunner beacons nearby, where the Weapon reconstructed a pure version of the sequence to access the Spire. The Harbinger, having realized that there is something guiding the Master Chief, scanned the Weapon and confirmed her existence while the Weapon was accessing the data strands beneath the Forerunner beacons.{{Ref/Reuse|sequence}} John-117 and the Weapon returned to the Command Spire, first passing through the Nexus located at the base of the Spire. The Banished troops inside, despite being reinforced by [[Sentinel Aggressor]]s that were in support of initiating the Reformation, failed to fend off the Spartan, and John-117 uploaded the Weapon into the Nexus to activate the gravity lift to access the Spire. While the Weapon was in the system, the Harbinger hijacked the Weapon's routines,{{Ref/Quest|Id=nexus|HI|Reformation|Nexus}} which, when paired with Despondent Pyre's encephalon,{{Ref/Reuse|sequence}} would correctly initialize the Reformation. However, the Weapon infiltrated the systems and retrieved Pyre's encephalon, that would allow her to halt the Reformation.{{Ref/Reuse|nexus}} John-117 and the Weapon entered the Command Spire, where they defeated the Banished and Sentinel defenses, including Adjutant Resolution, then shut down the Reformation.{{Ref/Quest|Id=commandspire|HI|Reformation|The Command Spire}} However, the Silent Auditorium was already partially rebuilt, and Escharum asked the Harbinger if that would be sufficient to carry out her plans, but she was unsure.{{Ref/Quest|Id=repository|HI|Reckoning|Repository (Halo Infinite level)|Repository}}

When Fernando Esparza flew ''Echo 216'' towards the crumbling Command Spire to pick up John-117, Jega 'Rdomnai revealed himself in the cockpit, having boarded the Pelican at some point.{{Ref/Reuse|commandspire}} The Sangheili took Esparza hostage, using the pilot as a bait to lure John-117 into a confrontation with Escharum.{{Ref/Reuse|repository}} To escape the crumbling Spire, John-117 entered a portal activated by the Weapon.{{Ref/Reuse|commandspire}} They were transported to the Repository, where they fought through Banished troops and Sentinels to the surface,{{Ref/Reuse|repository}} and, from there, they stormed the House of Reckoning, destroying the Banished defenses along the way.{{Ref/Quest|Id=road|HI|Reckoning|The Road (level)|The Road}} Inside, Escharum had John-117 fight through multiple waves of Banished troops in two arenas constructed from UNSC ordnance and buildings. John-117 fought Jega 'Rdomnai in a duel, emerging victorious and finally confronting Escharum at the chamber where Esparza was held. Escharum protected himself with a shielding system which redirected gunfire to the gravity wells holding Esparza. The Weapon helped John-117 locate and destroy the relay transmitters supporting the shielding system, allowing the Spartan to breach the shields and take down Escharum. In his final moments, Escharum assured John-117 that his death will only inspire further conflict. With Esparza rescued, the trio recovered ''Echo 216'' and Esparza flew John-117 to the Silent Auditorium to stop the Harbinger.{{Ref/Quest|HI|Reckoning|House of Reckoning}}

Although the Banished set up defenses at the Silent Auditorium to protect the Harbinger, John-117 breached the main chamber with the help of Adjutant Resolution. The Spartan fought through the Banished forces defending the Harbinger, and the Harbinger herself as she interfaced with the transmitters in the main chamber to locate members of her species, the Endless. Despite the Weapon's attempt to intervene with the transmission, and John-117 defeating the Harbinger in battle, the Harbinger claimed her people have been found, and that they would be unleashed. The Auditorium began to collapse, but a portal suddenly appeared, allowing the two to escape. On the other side of the portal, they found themselves having traveled three days into the future. They were extracted by ''Echo 216'', and taken to Outpost Tremonius with the intention of finishing the fight.{{Ref/Quest|HI|Endless|Silent Auditorium}}
