[[File:HINF Silent Auditorium building.png|250px|thumb|left|The [[Silent Auditorium (location)|Silent Auditorium]] was where the Xalanyn were sentenced by the Forerunners to imprisonment 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 [[United Nations Space Command]] 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. 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}} Cortana travelled to Installation 07 to unlock its secrets; she consolidated her presence and core processes at the Silent Auditorium.{{Ref/Reuse|enc22p423}} She also locked the Despondent Pyre in her cradle in the [[Conservatory (location)|Conservatory]] and restricted the monitor's access to the ring's defensive network.{{Ref/Novel|Id=rp30|TRP|30}}

[[File:H5G-Infinity&Guardian.jpg|250px|thumb|left|The entirety of the [[United Nations Space Command]] armed forces were fractured by the [[Guardian Custode|Guardians]] as part of the [[Created]]'s [[The Reclamation|rise]].]]  

In [[2559]], the [[Jiralhanae]] [[Atriox]], [[Warmaster|leader]] of a group of mercenary raiders known as the [[Banished]], discovered information on [[Installation 00]] regarding the existence of the Xalanyn.{{Ref/Book|Id=enc22p25|Enc22|Page=25}} Seeking to uncover this secret hidden by the Forerunners, Atriox returned to the galaxy following the events of [[Operation: WOLFE]],{{Ref/Novel|SoR|Epilogue}}{{Ref/Book|Enc22|Page=423}} then prepared his Banished forces to travel to Installation 07.{{Ref/Book|Id=enc22p423|Enc22|Page=423}} During his preparations for the journey to Installation 07, Atriox was personally confronted by Cortana.{{Ref/Quest|Id=repository|HINF|Reckoning|Repository (Halo Infinite level)|Repository}} The Banished had united the Jiralhanae clans across the Jiralhanae homeworld [[Doisac]] and its moons, and staged a defensive against the Created in their home system, where they fought against Cortana's forces.{{Ref/Book|Id=Enc22p446|Enc22|Page=446}} The Jiralhanae declared his independence from Cortana, and thus, opposition against the Created. In a show of force for Atriox's defiance, Cortana [[Razing of Oth Sonin|commanded her Guardians to destroy Doisac]] in the middle of her conversation with Atriox.{{Ref/Reuse|repository}} Resolved to access the ring's secrets and exact revenge against Cortana, Atriox led his Banished forces comprised of [[Jiralhanae]], [[human]]s, [[Sangheili]], [[Unggoy]], [[Mgalekgolo]], and [[Kig-Yar]] to Installation 07.{{Ref/Reuse|enc22p423}}

Meanwhile, 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 down Cortana, then return her to the ''Infinity'' for deletion.{{Ref/Reuse|foundation}}{{Ref/Game|Id=rf4|HI|Audio log (Halo Infinite)#Recovered Files 2|UNSC Audio log|Detail=Recovered Files #04 - The Weapon}} A plan was formed, with the initial intent to send [[Blue Team]] to the surface to retrieve Cortana, though this was later revised to only 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.{{Ref/Reuse|rf4}}{{clear}}

On [[2559#December|December 12, 2559]], {{UNSCShip|Infinity}} and her escort fleet, which included six {{Class|Mulsanne|light 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}}{{Ref/Reuse|foundation}} Upon arrival, the weakened 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}} The Banished had arrived at the ring earlier, and began fortifying on the ring's surface to neutralize Cortana.{{Ref/Reuse|enc22p25}}

Warmaster Atriox personally led Banished raiding parties aboard the ''Infinity'' in search of the Weapon,{{Ref/Reuse|ia4}}{{Ref/Quest|HI|Reformation|The Sequence|Quote=Atriox came for you.

John-117 ordered Fireteam Taurus to escort 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 hangar bay and into space.{{Ref/Quest|Id=wg|HI|Ringfall|Warship Gbraakon}}{{Ref/Mag|Id=GI341|Game Informer|341|page 43}}

In the region south of Silent Auditorium, the Banished set up three anti-air [[Kywasky Workshop Gorespike cannon]]s, which fired at numerous UNSC aircrafts landing at the area.{{Ref/Game|Id=r4|HI|Audio log (Halo Infinite)#Ringfall 2|UNSC Audio log|Detail=Ringfall #04 - Run and Guns}} This region became the most active battleground in the first 48 hours of the conflict.{{Ref/Quest|HI|Reformation|FOB Hotel|Quote=There we go — another FOB is ours. this one was built on of the most active battlegrounds in the first 48 hours of the war. UNSC and Banished records both suggest that it was absolute chaos. It raged all over, but nowhere quite as intensely as the island just north of us. Where we got shot down, you might recall.|Quotee=The Weapon}} Recognizing the threat posed by the cannons, Spartan Hudson led Fireteam Taurus and made landfall in this region, where they fought through Banished patrols, with sniper support from Spartan [[Nina Kovan]], to disable the three cannons.{{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—an explosion at the Silent Auditorium—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. The second frigate crashed between the three Gorespike cannons.{{Ref/Quest|Id=pdown|HI|Graveyards|[[Pelican Down (Halo Infinite level)|Pelican Down]]}} A third frigate was bisected, leaving its remains drifting in space.{{Ref/Quest|HINF|Ringfall|Warship Gbraakon|Detail=[[:File:HINF Warship G engines overload.png|A bisected frigate can be seen from the bridge viewport]]}} 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}}

===Cortana's destruction and the ring fractures===

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

While UNSC forces scattered over the ring and fought against the Banished forces, Atriox confronted Cortana at the 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. Having consolidated her presence and core processes at the Silent Auditorium and seemingly locked down by the Weapon deployed from {{UNSCShip|Infinity}},{{Ref/Reuse|enc22p423}} Cortana realized her mistakes but 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 activate the ring, Cortana initiated a local self-destruction sequence at the Auditorium, killing herself, fracturing the ring's surface, and leaving the installation inoperable for the Banished.{{Ref/Reuse|enc22p25}}{{Ref/Quest|Id=sareveal|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 the Banished.{{Ref/Reuse|wg}} Cortana, in hopes of John-117's survival, predicted he would stop the Banished from accessing the Silent Auditorium; she prevented the Weapon's deletion protocol so she could assist him,{{Ref/Reuse|sareveal}} 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 deactivated, crashing on the ring by [[2560]].{{Ref/Reuse|guardian}}

During the destruction event, Cortana also initiated an emergency translocation protocol, intending to disorient the Banished and stall their efforts.{{Ref/Reuse|enc22p423}} Installation 07, along with the debris from the space battle, was transported away from 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 the third Gorespike cannon, allowing more UNSC aircrafts to land on the ring.{{Ref/Reuse|r4}}

Despite the explosion, the Banished possessed a larger control of the ring, with some UNSC forces gathering on one of the fragments.{{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}} this region became known as the "Red Zone".{{Ref/Novel|Id=rp13|TRP|13}}{{Ref/Novel|Id=rp14|TRP|14}}{{Ref/Game|HI|Id=r6|Audio log (Halo Infinite)#Reverie 2|Spartan Audio log|Detail=Reverie #06 - Weakness}} The Banished had deployed their [[Banished outpost|prefabricated outposts]],{{Ref/Novel|Id=rp6|TRP|6}} [[Banished Harvester|resource harvesters]],{{Ref/Game|HI|Id=r2|Audio log (Halo Infinite)#Reverie 2|Spartan Audio log|Detail=Reverie #02 - Debrief}} and signal disruptors as well as broadcast towers—these continually interfered with the UNSC's short-range communications and made long-range communications nearly impossible.{{Ref/Reuse|rp13}} The Banished also endeavored to find alternate means to take control of the ring; the Bloodstar [[Gorian]] searched for the ring's [[Conspectus network]] hubs, which would grant him access to the ring's defense systems. Gorian stole [[Kate Stalling]]'s research on the Conspectus network and directed the excavation operations to locate the facilities.{{Ref/Novel|Id=rp22|RP|22}}

 

On one of the fragments to the west, a large group of survivors led by Commander [[Etana Hensler]] and Spartan [[Hudson Griffin]] established a base of operations in the wreckage of the ''Mulsanne''-class frigate {{UNSCShip|Mortal Reverie}},{{Ref/Reuse|rp13}}{{Ref/Novel|Id=rp9|TRP|9}} discovered by Spartan [[Vedrana Makovich]].{{Ref/Reuse|hafh}} Numerous survivors from the ''Infinity'' gathered at the crash site, including naval personnel, army troopers, marines, ODSTs, and Spartans; however, the remaining half of the survivors held no prior combat experience, being [[Unified Earth Government]] personnel, scientists, retail specialists, and support staff.{{Ref/Novel|Id=rp15|TRP|15}} Lieutenant [[TJ Murphy]] was put in charge of providing military training to supply staff and non-military personnel.{{Ref/Reuse|rp13}} Under the leadership of Commander Hensler and Spartan Griffin,{{Ref/Reuse|rp13}} the UNSC forces at the ''Reverie'' ran numerous 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}} The bases were hastily deployed to monitor Banished activities and launch incursions against raiding parties, supply depots, and other targets, but by [[2560#January|January 2560]], only a handful remained within UNSC control. Although the ''Infinity'' launched its sophisticated array of [[UNSC battle network]] communications satellites upon the ambush, most appeared to have been destroyed by the Banished.{{Ref/Reuse|rp13}}

 

On [[2560#January|January 20, 2560]], Stone and Kovan conducted a recon sweep deep inside the Red Zone.{{Ref/Reuse|rp14}} They observed that Banished forces were only unified under Escharum, with internal competition among its members. Kovan reported their findings to Griffin, and suggested that an attempt on Banished [[War Chief]] [[Escharum]]'s life may fragment the Banished leadership.{{Ref/Reuse|r6}} 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]] on an assassination mission on Escharum. Griffin left [[Bertold Vettel]] in his stead with Hensler to co-lead the UNSC forces at the ''Reverie''.{{Ref/Reuse|rp15}}{{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 the 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}}

{{Main|Battle of the Mortal Reverie}}

On the evening of January 31,{{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]] in [[Battle of the Mortal Reverie|an assault on 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.}} Pursued by small Banished parties, UNSC survivors scattered and fled into mountains or the surrounding area. Escharum ordered Banished troops to capture human survivors and collect dead Spartans from the battlefield—making it impossible for escapees to scavenge gear from their dead comrades.{{Ref/Novel|Id=rp18|TRP|18}}

At some point after the ring's fragmentation, the [[511th Infantry Division]] established a base of operations in [[Fragmentation|a canyon]] and are surveying that fragment. While fighting off [[Sentinel]] patrols and [[Banished]] talons, they were attempting to make contact with UNSC forces in comms range.{{Ref/Site|Id=cf|URL=https://www.halowaypoint.com/news/canon-fodder-foundations|Site=Halo Waypoint|Page=Canon fodder: Foundations|D=12|M=1|Y=2022}}

[[File:HINF BanishedCampConcept.jpg|thumb|350px|left|Following the fall of the ''Reverie'', the Banished consolidated their control over the ring; Banished outposts were constructed at strategic locations, especially around key Forerunner structures.]]

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}} Small, unofficial UNSC squads—such as the [[Gravediggers]], [[Hatetriox]], and the [[boat crew]]—survived by roaming the region and conducted guerilla operations where able; an ongoing leaderboard of kills and accomplishments circulated by word of mouth.{{Ref/Novel|Id=rp21|TRP|21}} 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}} [[Prisoner of war|prisoners of war]] were 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/Reuse|rp20}}{{Ref/Quest|HINF|Connections|Redoubt of Sundering|Quote=This must be where they processed prisoners before sending them to the Tower.|Quotee=The Weapon}} Many were transported to Escharum's base, the [[House of Reckoning (location)|House of Reckoning]],{{Ref/Reuse|tower}} where they went through the Trials of Atriox: a ritual in which they defend a large room from multiple waves of Banished troops. If they survived, they were fed food and water, then went through the trial again on the next day.{{Ref/Novel|Id=tor|Halo: Trial of Reckoning}} 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]] on March 3: 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|Jaide]] and [[Rosado]] managed to hijack a [[Barukaza Workshop siege-hauler]] carrying artifacts from Annex Ridge.{{Ref/Reuse|ahap}}

 

 

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 would expedite 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 also seek 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, so she can 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 [[Site Novem|the excavation site]], Spartans Makovich and [[Theodore Sorel]] correctly deduced that Escharum was searching for the Monitor. Over the next three weeks, the two stalled the Banished's excavation efforts by sabotaging the excavation machinery and disrupting supply lines.{{Ref/Game|Id=tp|HI|Audio log (Halo Infinite)#Scattered 2|Spartan Audio log|Detail=Scattered #04 - The Prize}} Despite Makovich and Sorel's sabotage efforts, the Banished completed the excavation by May 15.

On April 26, Gorian and 'Rdomnai reached a Conspectus network hub and used a human prisoner as a [[Reclaimer]] to extract its data on the ring's current coordinates as well as its defensive systems. Observing the proceedings, Spartan [[Bonita Stone]]—having infiltrated the structure while investigating Outpost Tremonius—attacked the excavation team, aiming to retrieve the data stored within the sylloge node, thereby disrupting Escharum's plans. After Stone succeeded in stealing the node, she had her personal AI [[Ouco]] copy the data and then corrupt the node. During her escape, she was ambushed and killed by 'Rdomnai. As Stone's last act, she hid the uncorrupted data chip on herself, while the corrupted data node which was retrieved by Gorian and 'Rdomnai, unaware of Stone's sabotage.{{Ref/Novel|Id=rp28|TRP|28}} Gorian and 'Rdomnai then joined the Banished forces at [[Site Novem]] to breach the [[Conservatory (location)|Conservatory]] in search of Despondent Pyre.{{Ref/Novel|Id=rp32|TRP|32}}{{Ref/Novel|Id=rp34|TRP|34}}

Stone's lifeless body was found by her teammate Nina Kovan and the [[boat crew]] on the next day. They recovered the data chip, and was later approached by submonitor [[091 Adjutant Veridity]], who revealed Stone's data chip contained the ring's Conspectus network data, including the ring's galactic coordinates. Led by Veridity, the boat crew set out to the Conservatory to free Pyre from Cortana's lockdown and decrypt the data.{{Ref/Novel|Id=rp30|RP|30}} On May 9, the team arrived at the Conservatory's main chamber. Spartan [[Tomas Horvath]], having joined the team while they were en route to the Conservatory,{{Ref/Novel|Id=rp31|RP|31}} deactivated the barrier and awaken the monitor. Although Pyre was initially uninterested in offering any assistance, upon hearing news of the Harbinger being released, the monitor decrypted the data and granted access to the beacon towers. She also gave the humans a data key that they must insert into the central plinth of a beacon tower in order to transmit the ring's location and data to human-occupied space. However, Pyre ordered Veridity to remain with her to counter the Harbinger, leaving the boat crew to travel to the beacon tower without Veridity's presence.{{Ref/Reuse|rp34}}  

 

On May 14, the boat crew translocated to the vicinity of a beacon tower near the Conservatory. Kovan successfully broadcasted the ring's location into space using a beacon tower, hoping to draw UNSC reinforcements to Zeta Halo.{{Ref/Reuse|rp35}} However, the Banished was alerted to the presence of the boat crew, and led reinforcements to their slained guards at the beacon tower.{{Ref/Novel|Id=rp36|TRP|36}} In [[Battle of the beacon tower|the ensuing battle]], while Kovan fought off Banished troops,{{Ref/Novel|Id=rp39|TRP|39}} Horvath managed to kill Gorian, but was teleported away.{{Ref/Novel|Id=rp38|RP|38}} At this point, the boat crew has taken multiple casualties, leaving only three survivors: Kovan, [[Erik Bender]], and [[Robin Dimik]]. As the Banished surrounded the trio, they were rescued by Veridity, who flew in and fired her [[focus beam]] at the Banished, then teleported the survivors to a safe location elsewhere on the ring.{{Ref/Reuse|rp39}}

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

However, while en route to the Command Spire, ''Echo 216'' crash landed at the region south of the Silent Auditorium, having sustained damage from anti-air fire from the three Gorespike cannons, which had been reactivated. 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}} During this time, John-117 also liberated [[FOB Kilo]], shut down the Banished operations at [[Riven Gate (location)|Riven Gate]] as well as [[Annex Ridge (location)|Annex Ridge]], and eliminated the Mgalekgolo pair known as [[Myriad]].{{Ref/Novel|Id=Whispers|Halo: Whispers from the Pyre}}

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/Reuse|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/Reuse|repository}}

{{Quote|Our battle ends here. Bear witness! Our story will become legend. Told by those that survive you.|Escharum to John-117 as he prepare to fight John-117.{{Ref/Quest|Id=hor|HI|Reckoning|House of Reckoning}}}}

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.{{Ref/Reuse|hor}} However, after Escharum's death, Atriox would make his survival known, giving the Banished a newfound resolve and confidence to fight for the control of the ring.{{Ref/Reuse|enc22p423}} With Esparza rescued, the trio recovered ''Echo 216'' and Esparza flew John-117 to the Silent Auditorium to stop the Harbinger.{{Ref/Reuse|hor}}

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|Id=sa|HI|Endless|Silent Auditorium}}

In the following days John-117, with the assistance of both Esparza and the Weapon, carried out anti-Banished operations and UNSC rescue missions. He managed to destroy eight Banished outposts, recapture eleven more FOBs, rescue twenty-five Marine squads and kill fourteen high-ranking members of the Banished plus the leader of a Gasgira patrol group known as [[Skimmer Alpha]]. Meanwhile, Atriox, having survived the destruction of the Auditorium, discovered the whereabouts of the Endless and finally released them from their one hundred thousand years of imprisonment. Atriox's sudden return gave to the Banished a newfound resolve and confidence.{{Ref/Book|Id=En423|Enc22|Page=423}}
