'''''2552''''' was the penultimate year in the [[Human-Covenant War]], during which the [[human]]s of the [[United Nations Space Command]] nearly saw utter defeat and extinction, though the tide turned, and with the help of the [[Sangheili]], won the Human-Covenant War. The [[Covenant Empire|Covenant]] were at the peak of their power and reach in 2552, with major assaults on the Human [[Inner Colonies]] and an invasion followed by a [[Battle of Earth|prolonged engagement]] on their home planet, [[Earth]].<ref>'''[[Halo 2]]''', level ''[[Cairo Station (level)|Cairo Station]]''</ref><ref>'''[[Halo: Ghosts of Onyx]]'''</ref><ref>'''[[Halo 3]]''', level ''[[The Storm (Level)|The Storm]]''</ref> During the [[Battle of Installation 04|battle]] at [[Installation 04]], the galaxy found its first large outbreak of the [[Flood]] threat in over a hundred thousand years.<ref>'''[[Halo: Combat Evolved]]''', level ''[[343 Guilty Spark (level)|343 Guilty Spark]]''</ref><ref>'''Halo: Combat Evolved''', level ''[[The Library (Level)|The Library]]''</ref> Over two months later, an even larger outbreak occurred at [[Installation 05]].<ref>'''Halo 2''', level ''[[Sacred Icon]]''</ref>

[[File:SC new.png|200px|thumb|right|John-117 leading Marines on Installation 04.]]
*SPARTAN-117 leads a [[UNSC Marine Corps|Marine]] force to board the ''Truth and Reconciliation''. They recover Keyes and escape aboard a [[Type-25 Troop Carrier|Covenant dropship]].

'''September 20'''

*Keyes orders SPARTAN-117 to find the "[[Silent Cartographer]]", a map room that will reveal the location of the [[Control Room]]. Keyes leaves to lead an assault on a Covenant weapons cache.
*Having found the map room and the pertinent information, Cortana directs a [[Echo 419|Pelican]] to take them to the area where the ring's Control Room is. Upon reaching the Control Room, Cortana transfers to the Control Room's computer and directs SPARTAN-117 to stop Keyes from accessing the 'weapons cache', really a [[Forerunner]] research and quarantine facility.
*SPARTAN-117, without Cortana, enters the facility but is unable to locate Keyes. Instead, he discovers the "Flood" and is forced to retreat. He links up with marines and takes command of the surviving members of Keyes' team and together they fight their way to the extraction point. However, the Spartan is conscripted by the "[[343 Guilty Spark|Monitor of Installation 04]]" and teleported away before he can be evacuated with the surviving members.

'''September 21'''
*The Monitor takes [[John-117]] to the ring's "[[Library]]" to retrieve the "[[Index]]", a device needed to activate the ring's primary weapon. Having retrieved the Index, the [[Monitor]] teleports the [[Spartan]] back to the Control Room where an irate Cortana confiscates the Index and prevents the ring from firing. SPARTAN-117 and Cortana flee a now-hostile 343 Guilty Spark and [[Sentinel]]s.
*To forestall the ring from being activated manually, SPARTAN-117 disables the ring's three [[Pulse Generator]]s. This is to buy time to destroy the ring by activating the auto-destruct on the {{UNSCship|Pillar of Autumn}}. Only Keyes neural interface can activate the ship's self-destruct, and SPARTAN-117 embarks once more to rescue the captain.
*Cortana teleports the Spartan to the Flood-overrun Covenant cruiser where Jacob Keyes is being held. Alas, the pair arrives too late to save Keyes, who has been merged into a [[Brain Form]]. SPARTAN-117 retrieves the neural interface by punching in the former-captain's head. Cortana downloads the necessary codes, and the duo returns to the {{UNSCship|Pillar of Autumn}} on a captured [[Banshee]].

'''September 22'''
*343 Guilty Spark overrides the auto-destruct sequence, forcing SPARTAN-117 to manually destabilize the ship's still-functioning fusion cores. SPARTAN-117 and Cortana then escape the resulting explosion and the fragmentation of the ring aboard a Longsword.
*[[Avery J. Johnson|Staff Sergeant Johnson]], [[Lieutenant Haverson]], [[Warrant Officer Polaski]], [[Corporal Locklear]] also escape the destruction of the ring aboard a Pelican.
*SPARTAN-117 and Cortana rendezvous with Johnson's group in Installation 04's debris field. They also recover a set of [[cryo chamber]]s, one which contains [[SPARTAN-058]].
*The Battle of Installation 04 ends. [[Stacker|Gunnery Sergeant Stacker]] and PFC [[Chips Dubbo]] survive, but it is unknown how they do.
*[[Skirmish over Threshold]]: As the [[Longsword]] and [[Pelican]] are not jump capable, the UNSC survivors assault and capture the ''[[Ascendant Justice]]'', a Covenant warship and apparently the flagship of the Covenant Fleet sent to Installation 04. They then set course for Reach.
*[[Jersey Morelli]] confronts his mother about having an affair.

'''September 23'''
*A Time/Date Record Anomaly continues from this point in the narrative, resolved above on Sep 7, 2552.

====September's Anomaly====
After the recovery of a Forerunner device on Reach, the members of an organized resistance comprised of SPARTANs from Reach and survivors of the Battle of Installation 04 are in some sort of time anomaly, causing them not to be in the "correct timeline".<ref>'''Halo: First Strike'''</ref> What is known is that the events taken place with the possession of the device take place after September 7.

[[File:Fight on Ascendant Justice.png|thumb|250px|John-117 and Marine survivors fighting on the ''Ascendant Justice''.]]

Johnson]], [[Elias Haverson|Lieutenant Haverson]], Warrant Officer Polaski, and Corporal Locklear jump to Slipspace on board the Covenant/Human hybrid ship {{UNSCship|Gettysburg}}-Ascendant Justice'', and discover that the shard seems to have the ability to bend both space and time.

'''September 12'''
*The ''Gettysburg/Ascendant Justice'' arrives for refit and provisioning in [[Eridanus system]] and meets with the rebels under [[Jacob Jiles|Governor Jiles]]. Dr. Halsey sedates Spartan 087, [[Kelly]], and absconds with her on Governor Jiles' personal ship, the {{Class|Chiroptera|Stealth Vessel|}} [[Beatrice]]. Before she goes, she gives the alien artifact to Corporal Locklear, with implicit instructions to destroy it.

'''September 13'''
*UNSC forces aboard the ''Gettysburg/Ascendant Justice'' win a crucial victory at the [[Operation: FIRST STRIKE|Battle of the ''Unyielding Hierophant'']]. [[SPARTAN-093]], Lieutenant Haverson of ONI and Vice Admiral Whitcomb are killed. The survivors, now aboard the singular {{UNSCShip|Gettysburg}} and with a captured Covenant slipspace drive, depart for Earth to warn of the impending Covenant invasion.

===October===
'''Unknown Date'''
*An Edict from the Office of the High Prophet of Truth orders that in the virtue of the Jiralhanae, all Sangheili posted with the [[Fleet of Profound Solitude]], the [[Fleet of Tranquil Composure]], and the [[Fleet of Inner Knowledge]] to be completely replaced by Jiralhanae. Each removed Sangheili to be assigned other duties. In celebration, all imprisoned or criminal Jiralhanae were released, rehabilitated, and pardoned.<ref>'''Halo Wars''': ''Halo Timeline''</ref>
*The {{UNSCShip|Red Horse}} is sent to Installation 04's debris field in the Soell system to scout the area for survivors. They detect the [[prison ship]] ''[[Mona Lisa]]'' and deploy Marines into the ship. Soon after, it is revealed that the ship is infested by the Flood and was used by the Office of Naval Intelligence as a laboratory to test the parasite on prisoners. The infestation is contained as the ''Red Horse'' unleashes a [[Shiva-class nuclear missile]] on the ''Mona Lisa'', destroying it.<ref>'''Halo: Evolutions - Essential Tales of the Halo Universe''' - "The Mona Lisa"</ref>

*SPARTAN-117 deploys to New Mombasa in an attempt to capture the High Prophet of Regret. Before this can happen, the assault carrier initiates a slipspace jump within the city, escaping Earth and severely damaging the city in the process. The {{UNSCShip|In Amber Clad}}, with SPARTAN-117 aboard, successfully pursues the carrier through slipspace.
*Immediately after Regret's retreat, an additional [[Jiralhanae]]-led Covenant occupation force is inserted to New Mombasa, as a part of the Prophet of Truth's plan to eventually replace the Sangheili with the Brutes as the Covenant's primary warrior race. For the rest of the day, UNSC and Covenant forces battle for control of the city. Meanwhile, the Covenant fleet begins the process of uncovering the [[The Portal|Ark portal]].
*The [[ONI Alpha Site]] in New Mombassa is destroyed by the combined forces of the UNSC and the [[New Mombasa Police Department]], led by Corporal Miles and and PFC Crespo, in order to prevent the Covenant from accessing it.

'''November 3'''
*The [[Great Schism]] begins.
*The {{UNSCShip|Dusk}} arrives at Delta Halo and witnesses the final stages of the Battle of Installation 05. She retreats to Earth via a [[Slipstream space#Slipspace wake|slipspace wake]] caused by the Forerunner ship.

'''November 8 through November 17'''
*[[Battle of Mare Erythraeum|The Battle of Mare Erythraeum]] takes place on [[Mars]], resulting in a victory for the Covenant Loyalists. Following the battle, Colonel James Ackerson, leader of the UNSC forces on Mars, is taken hostage and interrogated by the Jiralhanae Commander [[Lepidus]] onboard the Covenant cruiser ''[[Triumphant Declaration]]'', who tells them of a Forerunner device linked to the [[Halo Array]] known as the [[Key of Osanalan]], and that it can be found in [[Cleveland]], [[Ohio]].
*[[Battle of Cleveland]]: The Covenant Loyalist Army invades Cleveland via the cruiser ''[[Harbinger of Piety]]''. The Loyalist forces, under the direction of the [[Minister of Inquisition]], are searching for the whereabouts of the Key of Osanalan (In reality, the Key of Osanalan was made up as a ploy by James Ackerson to prevent Cleveland from being glassed and to save the life of his brother [[Ruwan Ackerson|Ruwan]].) When Ruwan learns the reason the Covenant are invading, he devises a plan with [[Twyker|Sergeant Twyker]], involving being injected with organic tracking material. Ruwan confronts Lepidus at Chagrin Falls and tells him that ''he'' is the Key of Osanalan. Ruwan is taken onboard the ''Harbinger of Piety'' to meet with the Minister of Inquisition, who vows to spare Earth in exchange for Ruwan's knowledge. Ruwan plays along until the Prophet informed him that he knew of the organic tracking material, believing it to be a rescue beacon. In reality, it was a tracking vector. With his last words, he told the Prophet to "kiss [his] ass" right before [[Nassau Station]] used its [[Magnetic Accelerator Cannon]] to destroy the ''Harbinger of Piety''.
*Lepidus realizes that the Key of Osanalan does not exist, and returns to the ''Triumphant Declaration'' to confront Colonel Ackerson about this deception. Ackerson mocked the Brute Chieftain, saying that his belief in the Key of Osanalan was just one example of how their pompous arrogance would cost them the war. Moments later, Ackerson is beheaded by Lepidus.
*[[Sergeant Major Johnson]] arrives back on Earth and gets clearance from [[Lord Hood]] to question [[Vergil]] about the artifact the High Prophet of Truth is digging up near Voi.

'''November 17'''<ref name="timeline"/>

Meanwhile, [[Battle of Sector Six]] takes place at [[Pawa]], [[Afghanistan]]. There, numerous Marines of the [[2nd Orbital Drop Shock Trooper Battalion|2nd ODST Battalion]] track SPARTAN-117's descent. SPARTAN-117 eventually lands in the [[East African Protectorate|East African]] jungle near [[Mount Kilimanjaro]], going unconscious for hours.

*The Prophet of Truth's Dreadnought lands in the middle of [[The Portal|the Portal]] near [[Voi]], [[Kenya]]. During the last few weeks, Truth's fleet of twenty-odd [[CCS-class battlecruiser|battlecruisers]] and two [[CAS-class assault carrier|assault carriers]] have almost entirely uncovered the Portal and occupied the entire region surrounding it.

*UNSC forces [[Raid on Kilimanjaro|recover]] John-117 from a jungle near [[Mount Kilimanjaro]]. In the underground facility of [[Crow's Nest]], a plan is formulated to launch an aerial strike on Covenant anti-air defenses in the town of [[Voi]] in order to prevent the Prophet of Truth from activating the Forerunner artifact. After repelling a Covenant assault in Crow's Nest and destroying the base in the process, a UNSC strike force led by John-117 retakes the Covenant-held [[Tsavo Highway]].

*[[Battle of Voi]]: John-117 and a Marine strike force enter Voi and gradually push back the city's Covenant occupiers, destroying the Covenant anti-air defenses in the city. An aerial strike force consisting of two frigates and numerous Longsword fighters assaults the Forerunner Dreadnought resting over the Portal artifact, but are unsuccessful in damaging the ship. Truth activates the portal and retreats through it to [[Installation 00]] along with his forces. At the same moment, a [[Unidentified Flood-captured battlecruiser|Flood-controlled ship]] slips in, crashing in Voi.

[[File:H3 TheArk Opening.jpg|200px|thumb|right|The Ark portal on Earth activates.]]

*UNSC forces make their way toward the crashed ship in order to overload its reactors and contain the Flood outbreak, just as the Sangheili [[Fleet of Retribution]] arrives and drops in reinforcements. After recovering a message by [[Cortana]] from the Flood ship, John-117 and the remaining human and Sangheili forces retreat from Voi, as the Fleet of Retribution glasses the city and its surroundings in order to contain the Flood.

*UNSC and Sangheili leaders gather aboard the Sangheili assault carrier ''[[Shadow of Intent]]'' to hear Cortana's message, which reveals there is a way to stop the Flood on the other side of the Portal. Despite Lord Hood's urging, Commander Keyes, along with the Master Chief and the Sangheili, enter the Portal with the Fleet of Retribution and two UNSC frigates.

'''December 11'''<ref>[http://halo.xbox.com/en-us/intel/featured/video/herofortitude/bfe5038b-314a-4f17-a6be-f7613e0e3788 '''Halo Waypoint''', ''Hero-Fortitude'']</ref>

*The [[Battle of Installation 00]]: The joint Sangheili-human force arrives at Installation 00 and immediately engages Truth's forces while the {{UNSCship|Forward Unto Dawn}} deploys ground forces to locate Truth. Despite being outnumbered three to one in space, the separatist fleet makes short work of the Covenant space forces. After locating Truth, the separatist-UNSC alliance launches an assault on the Ark's [[Forerunner Citadel|Citadel]] where Truth intends to activate the Halo Array. At the same time the former Covenant city ship ''High Charity'' arrives from slipspace and crashes on the Ark. Debris spread from the city-ship helps spread a new Flood infestation on the Ark.

*Truth is killed after John-117 and the Arbiter successfully attack the Citadel. Soon after, it is discovered that the Ark's foundry has created [[Installation 04B|a replacement]] for the destroyed Installation 04. Realizing that the ring could be used to fire a tactical pulse which would eliminate the Flood infestation, John-117 decides to light it. In order to do so, he enters the ruins of ''High Charity'' and recovers Cortana, who still possesses the Activation Index from the original Installation 04. ''High Charity'' is destroyed in the process.

*With the Index secure, John-117, Cortana, the Arbiter, and Sergeant Major Johnson travel to the replacement Installation 04, while the rest of the UNSC and Sangheili forces return to Earth on the ''Shadow of Intent''. In the control room, Johnson is killed as 343 Guilty Spark attempts to prevent him from activating the ring prematurely, as doing so would destroy the ring. John-117 destroys the monitor and begins the firing sequence for the Halo ring. SPARTAN-117 and the Arbiter then escape the control room by taking Johnson's Warthog to the ''Forward Unto Dawn'', which is holding position nearby.

*Due to the unstable, incomplete nature of the ring as it fires, the slipspace portal collapses as the ''Dawn'' enters it, causing it to be sheared in two. Cortana and SPARTAN-117 are in the hangar area at the time of the separation, and are thus left in the aft section of the ship, which falls out of Slipstream space at an unknown location, eventually drifting towards an [[unidentified planet]].

+*[[Battle of Cleveland]]: The Covenant Loyalist Army invades Cleveland via the cruiser ''[[Harbinger of Piety]]''. The Loyalist forces, under the direction of the [[Minister of Inquisition]], are searching for the whereabouts of the Key of Osanalan (In reality, the Key of Osanalan was made up as a ploy by James Ackerson to prevent Cleveland from being glassed and to save the life of his brother [[Ruwan Ackerson|Ruwan]].) When Ruwan learns the reason the Covenant are invading, he devises a plan with [[Twyker|Sergeant Twyker]], involving being injected with organic tracking material. Ruwan confronts Lepidus at Chagrin Falls and tells him that ''he'' is the Key of Osanalan. Ruwan is taken onboard the ''Harbinger of Piety'' to meet with the Minister of Inquisition, who vows to spare Earth in exchange for Ruwan's knowledge. Ruwan plays along until the Prophet informed him that he knew of the organic tracking material, believing it to be a rescue beacon. In reality, it was a tracking vector. With his last words, he told the Prophet to "kiss [his] ass" right before [[Nassau Station]] used its [[Magnetic Accelerator Cannon]] to destroy the ''Harbinger of Piety''.
+*Lepidus realizes that the Key of Osanalan does not exist, and returns to the ''Triumphant Declaration'' to confront Colonel Ackerson about this deception. Ackerson mocked the Brute Chieftain, saying that his belief in the Key of Osanalan was just one example of how their pompous arrogance would cost them the war. Moments later, Ackerson is beheaded by Lepidus.

 ==Trivia==
-*All five ''Halo'' games developed by [[Bungie]] take place in the latter half of this year.
+The first and second parts of 2552 equal 2+5=7 and 5+2=7, another one of Bungie's 7 references.
-*The numerical value of the year is one of Bungie's many references to the number [[seven]]. Specifically, adding the numerals results in 14, which has twice the value of 7. Adding the two halves of the year separately (2+5 and 5+2) results in a pair of sevens.
