Aloy/Synopsis

The story of the Nora Huntress, Aloy, in the Horizon series.
==Horizon Zero Dawn==
===The Eclipse and Meridian===
Aloy embarks on her quest to find out why she was outcasted at birth by the Nora tribe. She later joins the coming-of-age event known as the Proving, where she soon thwarts the Proving Massacre orchestrated by the Eclipse commander Helis, but not before she was almost put to near-death state as well as with her father figure Rost sacrificing his life to save her. A day later, Aloy wakes up inside the ruins of All-Mother Mountain, before proceeding to examine the Focus she took from an Eclipse soldier.
There she uncovers shocking information on it: a hologram of a woman that bears a striking resemblance on her, who is stumped if she is even her own mother, as well as why she was targetted in the first place, just because she resembles her. After watching Helis' past plan of attacking the Proving Massacre, Aloy later leaves the facility with Teersa. She is later brought to the main hall of the mountain where she sees a giant blast door, but to her surprise it didn't open at all.
She later stops the Eclipse cultists in the Ring of Metal within Devil's Grief with Sona and Varl's help, before she reaches Meridian to investigate a possible murder plot regarding Ersa. She is joined by Erend Vanguardsman on uncovering the perpetrator behind her demise, before it soon leads to a rogue Oseram known as Dervahl, who is bent on targetting the capital city as revenge for the deaths of his family from Jiran during the Red Raids. She later thwarts Dervahl's attack in Meridian, thereby saving countless civilian lives from being lost through his attempted bombing.
===In Pursuit of her Mother and the Old Ones===
After dealing with Dervahl, Aloy proceeds her way to Maker's End, once she dealt with the Eclipse in Rockwreath and stopping Olin Delverson, the Oseram traitor coerced by Helis to join the Eclipse. It is revealed that she is genetically connected to Elisabet Sobeck, an Old World, 21st-Century scientist, before she decides to explore the ruin while stopping the Eclipse stationed there. It is then revealed from one of the cultist's Focus that HADES, a rogue AI, initiated the kill order against her, due to her being genetically related to Sobeck.
Aloy visits the ancient ruin of Faro Automated Solutions to find out more what happened to the Old Ones in the distant past. There she finds out that the Faro Plague destroyed the ancient world, due to the reckless actions of an Old One named Ted Faro, but not before the mysterious man known as Sylens introduces himself to Aloy, being the one who knew about her connection to Sobeck. She later decides to visit the Grave-Hoard, erstwhile U.S. Robot Command, to know more what Project: Zero Dawn is.
===Project Zero Dawn and Infiltration to Sunfall===
From there Aloy deals with more of the Eclipse inside the ancient ruin, as well as facing off another Deathbringer, before reaching the end of the ruin where it is revealed a part of Project Zero Dawn: A top-secret superweapons program designed to curtail the Faro Plague. Realising that the staging ground for the project was within the former Bryce, Utah, Aloy is soon stuck with the realisation that it is located within the Shadow Carja bastion known as Sunfall.
Realising that the only way was to destroy the Eclipse Focus Network, Aloy decides to infiltrate the Eclipse's main base under Sylens' help in The Jewel to crash the said network. This would allow her to infiltrate Sunfall unseen, but she soon personally encounters HADES on top of the derelict Tallneck, with the AI warning her of her interference, before Aloy finally destroyed the module. In the process she soon frantically escapes the main base after HADES unleashed a kill order against her, but Aloy successfully escaped a near-death experience and is angered at how Sylens hid the truth regarding HADES' existence inside the base.
She later infiltrates Sunfall to find the Zero Dawn Project Facility that is located within the Shadow Carja Sun-Ring. From there she explores the facility from within, before finding out the truth regarding the end of the ancient Earth: Aaron Herres explained how the Faro Robots are unhackable and continuously devouring Earth's biosphere at an alarming rate. Aloy then realises that Operation Enduring Victory, Herres' campaign against the Faro Plague, was the only way to forestall Faro Plague which would give time for the Zero Dawn personnel to complete GAIA, a hyper-intelligent terraforming system seen by Aloy in the next hologram presentation by Sobeck used to revive the destroyed Earth back to extinction.
After seeing the presentations by Herres and Sobeck, Aloy soon traversed further into the facility and dealt with the Eclipse and Shadow Carja sent down after inadvertently causing the venting procedure to unlock the blast door into the facility. She later comes across Sobeck's room to retrieve the Alpha Registry master file and proceeded to download it, in order to open the door within All-Mother Mountain. She is later angered when Sylens truthfully but slowly reveals her birth, but not before Helis and his Eclipse army invaded the facility and with him incapacitating the former with a blast bomb.
===Helis and the Attack on Sacred Lands===
Aloy later wakes up within the Shadow Carja Sun-Ring, who is stripped of her gear, before Helis soon gloats over Aloy regarding her involvement in the waylaying of Eclipse ancient machine dig sites, as well as crashing the Eclipse Focus network and smuggling Itamen and Nasadi out of Sunfall. He also gloated to Aloy regarding him murdering Rost during the Proving Massacre. He soon reveals that he has sent the Eclipse to attack the Sacred Lands, prior to the destruction of the Focus network, as retaliation for her repeated interferences in his plans, before he sends her down the Sun-Ring, waiting to be executed in front of the Shadow Carja audience.
Aloy then faces a Corrupted Behemoth within the arena, but she uses the machine's strength as an advantage before she retrieves her weapons to deal with the machine accordingly before defeating it in the first place. Much to Helis' fury, Aloy soon escapes the Sun-Ring with the aid of Sylens, thus disclosing the maverick's past involvement with the cult.
However, due to the Sacred Lands being under Eclispe threat, Aloy soon parts ways with Sylens, before she hurriedly goes back to the Sacred Lands and repel the attack. Encountering more cultists along the way, Aloy later encounters many deceased bodies of Nora who valiantly fought against the cultists, before reaching Mother's Watch, which soon invigourated Sona's braves and Varl to fight back against the Eclipse. Aloy soon deals with the Corrupted Thunderjaw attacking the All-Mother Mountain, before destroying the machine, once and for all. Her actions saved the Nora from being exterminated, gaining the respect of many. She is later joined by Teersa and the rest of the Nora Matriarchs, before deciding to enter the ELEUTHIA-9 Brood-1 Facility, which is later revealed to be her real birthplace.
===The Birthplace and the Truth===
Traversing through the ancient room reveals more regarding the fate of the first Nora tribespeople: the APOLLO was offline that led to Lyceum, the learning centre of the Cradle Facility, being locked, leading to most of the inhabitants to only learn basic, kindergarten-level education. With Aloy being more suspicious, she later reaches the projector room before she uses her Focus to find a message left by the AI GAIA.
Aloy comes to a realisation that HADES was bombarded by a mysterious signal, turning out to be from the rogue AI Nemesis, Far Zenith's failed creation, and soon attempted to renege on GAIA by taking over the terraforming system to drive Earth into extinction, which in return caused most of her subordinate functions to turn into highly unregulated, chaotic self-entities unshackled from the system. However, GAIA overloaded the facility's reactor in an attempt to stop HADES from using the system to its own genocidal purposes, but nevertheless it was too late as all of her Subordinate Functions escaped from parts unknown. This caused an unintended effect of the system slowly breaking down, in spite of it being operational in the first place.
Aloy soon comes to realisation that the Derangement was due to HEPHAESTUS now being a self-aware entity, which led to once-docile machines being turned into hunter-killers in the first place. She also reveals that she was created by GAIA in an act of desperation to stop HADES from initiating another Faro Plague where this time there is no way of stopping it at all.
Shocked with the revelation regarding the true origins of her birth, Aloy soon leaves the abandoned facility, now in her plans to retrieve the Master Override in the ruins of GAIA Prime to forestall HADES permanently. Upon leaving ELEUTHIA-9, Aloy is greeted by the Nora who sees her as the "Anointed" but that soon turns into utter scorn for Aloy, as Aloy berated the entire Nora crowd for "worshipping" her, warning that the world is in utter danger because of HADES and it is considered worth fighting for. She then orders the rest to go to Meridian and prepare for the Eclipse and HADES' invasion in Meridian, before she parts ways to retrieve the Override.
===GAIA Prime===
Visiting the Bitter Climb that leads to the ruins of GAIA Prime, Aloy encounters an army of machines, as well as a Stormbird, before she dispatched all of them. She later visits the ruined facility as she enters inside. Traversing further into the destroyed ruins of GAIA Prime, Aloy then comes across a recording of what looked like Sobeck's final moments. Aloy realises that Sobeck sacrificed herself for the world, right after GAIA Prime's doors caused a huge gap that allowed the signal to be bled that would be enough for the Faro machines to detect it, with Sobeck sealing the door permanently, but not before she sacrificed herself, thereby saving GAIA from being completely destroyed.
Exploring further into the facility and subsequently into the control room, Aloy soon comes across a group of dead, desiccated bodies. She soon listens into another holographic recording, revealing that Ted Faro disabled the Alpha Privileges, as well as locking out the Zero Dawn personnel, before revealing that he destroyed the APOLLO database and all of its traces on it, claiming that Old World knowledge is a "disease", much to their shock and anger. Faro soon kills all of them through asphyxiation via ventilation. Aloy, in shock, could not comprehend what Faro had done, before Sylens' hologram showed up, finally revealing why humanity became as is, and with Aloy knowing that the Alphas died what they fought for. She later retrieves the Master Override and leaves the facility.
===The Daemon and CYAN===
Before preparing for the final battle, Aloy soon traversed through the Banuk lands, due to a rumoured threat happening within the Cut. From there she encounters the Banuk chieftain Aratak, who refuses to help Aloy out due to his experience of his expedition team getting slaughtered after a failed expedition within an Old World ruin known as Thunder's Drum. She later goes to The Shaman's Path, after helping Naltuk, in order to reach out the Banuk shaman known as Ourea. Dealing with the Frostclaw along the way, Aloy is soon able to reach Ourea's Retreat, before she sees the shaman in dismay and shock over her failed expedition to save CYAN from the "Daemon" inside Thunder's Drum. However, in order to gain Aratak's trust, she later willingly completed errands, before challenging Aratak for the Chieftain title.
However, Aloy was victorious against Aratak, which in return caused the latter to gain his trust, thereby gaining Aloy the Chieftain title in order to gain access to Thunder's Drum, which is now revealed to be the Firebreak facility, to save CYAN. With Aloy's help, she, Ourea and Aratak soon enter inside the Firebreak facility, before coming across several Daemonic Machines as well as corpses of the Banuk who were tragically killed during the failed expedition.
Aloy soon comes across a holographic module revealing the true nature of Firebreak facility spearheaded by its creators Anita Sandoval and Kenny Chau. She later comes down the facility as the trio fought off against a Daemonic Thunderjaw guarding the door leading to Cauldron EPSILON. After dealing with the machine, Aloy uses her spear to open the Cauldron's doors, thereby allowing themselves to enter the facility and save CYAN.
After exploring deeper into the facility, she, Ourea and Aratak come across at the Cauldron's Core, revealing an imprisoned CYAN under the grips of HEPHAESTUS, who turned out to be the "Daemon's" real identity. However, the rogue AI soon responds by sending a Daemonic Fireclaw to deal with the trio, as well as an army of Daemonic Machines. Aloy and the trio, however, outmatched the machine horde, before Aloy attempts to override the core. However, HEPHAESTUS responds by unleashing a power surge, knocking the trio out easily. Aloy only watches as Ourea uses her spear to expel HEPHAESTUS out of the Cauldron, thereby finally freeing CYAN and saving the Banuk from being exterminated by HEPH through its army of Fireclaws. However, Ourea was soon killed in the process, before Aloy and Aratak escaped the facility. Aloy soon reassures Aratak that Ourea's sacrifice will not be in vain. She then willingly relinquishes the Chieftain title back to Aratak, before she listened to many of CYAN's conversations regarding the Old World and the origin of Firebreak.
===The Battle of the Alight===
Soon after, Aloy heads back to Meridian to deal with the Eclipse and HADES. Aloy reaches the inside of the palace, as she warns Avad of the impending threat, before she later rappels down to fight off against Helis. Only this time she is far more capable in dealing with the Eclipse commander and after a few moments, Aloy was able to vanquish her father figure's killer. She soon repelled the machine invasion with the Oseram Cannons, but that was not enough as a Deathbringer managed to blast through the gates of Meridian Village. With less time left, Aloy hurriedly runs through the razed village all the way to the Alight that houses the Spire, the MINERVA tower, before encountering Varl, Erend and Talanah.
Ascending through the sacred ground, the group soon personally deal with HADES, who was attempting to use the MINERVA tower to revive the Faro robots buried underground. Despite HADES' attempts of sending an army of Corrupted Machines and having a powerful Deathbringer, Aloy and her team was able to vanquish the Deathbringer, thereby allowing her to use the Master Override against HADES as she stops the rogue AI, once and for all. Despite the celebrations, Aloy soon quickly headed further west to visit the Sobeck Ranch, which revealed Sobeck's final resting place, much to her own joy that she finally knew her "mother's" true identity.
==Horizon Zero Dawn: The Comic Series==
Aloy came upon two Sawtooths in the wilds close to Meridian a few weeks after the Battle of the Alight. Aloy engaged them in a battle, launching arrows from the Strider's back. While close in the wilderness, Talanah came to Aloy's rescue after spotting her engaged in combat and losing her own bow to one of the Sawtooths. Aloy sought Talanah's assistance in finding the other Sawtooth after beating the machine and realising it had gone.
The two followed the vehicle to a damaged caravan's location, where a large number of bodies were found. Talanah expressed shock that a machine could wreak such havoc, and Aloy responded that it was a "new breed" (later revealing to be an Apex-type machine) that needed to be stopped. The two heard pleas for assistance and hurried to save the only survivor of the caravan — a young Carja girl — who was being pursued by the Sawtooth. Together, Talanah and Aloy took down the predator by attacking the machine with their spears as Talanah backed them from a distance. They did this by using up all of Talanah's ammo.
Aloy spoke with Talanah about the existence of Apex machines, variants far more dangerous and deadlier than the original, as the Carja girl recovered from the terrible event, warning her that the majority of hunters would not be able to fight them. Talanah was given a supply of arrows by Aloy to replace her missing ammo before the two parted ways. In that moment Aloy soon planned her trek to find a GAIA backup.
==Horizon Forbidden West==
===Searching for the GAIA Backup===
Months have passed and with little success, Aloy spent most of her time exhaustively searching for a backup, while coming across the side effects of GAIA's absence: deadly overgrowth of Red Blight and supercell storms going out of control, which are ominous premonitions of yet another global extinction because of a failing and collapsing system.
She later comes across into another Old One facility, which is revealed to be owned by Far Zenith, but as soon as that happens Varl appears, much to her surprise. Despite her efforts to ignore Varl, she later reluctantly accepts him by giving him a Focus to join in on her mission to find the GAIA backup in the first place. Entering through the Zenith launch facility reveals the organisation's origins, as well as the Zenith's attempt to steal GAIA for their own purposes through an "asset" in the form of Hank Shaw.
Aloy soon destroys the Slitherfangs blocking the Data Center, before approaching a copy of GAIA backup. However, to her extreme annoyance and frustration, the "GAIA backup" was nothing more than a logic bomb, a massive computer virus perpetrated by Alpha HADES Travis Tate, due to Tate and Sobeck fully being aware of the Zeniths' attempted thievery.
===Sylens' Treachery===
After failing to find a GAIA backup, Aloy and Varl soon joined where they go back to Meridian, only for Marad to tell the duo regarding a suspicious event happened within the Spire regarding a red light flashing from above. Knowing that this is trouble, Aloy soon heads into the Quantum Processing Module where the lance she used is still embedded on it. However, Aloy soon realises that Sylens' "aid" was nothing more than mere trickery, as the spear was rigged and it dissolves into nothing, before an ominous red signal in the form of HADES is seen flying above the Spire's base. 
Aloy soon climbs the tower, before reaching the base, where she uses the spear into the node. She then confronts him regarding his treachery during the Battle of the Alight, before Sylens simply gave her the coordinates to the Forbidden West. Realising that her goal is to reach the West, Marad warns that the Tenakth-Carja embassy will be underway and entrance to the West is no easy task. She soon travelled west for days, before reaching the Barren Light, only to find out that the embassy was halted because of Bristleback infestations caused by Ulvund Freeholder's reckless mining.
===Barren Light===
She rendezvouses with Erend and Varl, before meeting up with Nozar, who only refuses her attempts to visit the Forbidden West, due to the embassy not commencing yet via his signal. Aloy ignores his warnings and visits the border, much to the ire of many Tenakth representatives. Except for the Marshal Fashav, Avad's cousin and a former Red Raid soldier, who only heard her requests. 
As the embassy between two fragile tribes commenced, a group of rebel Tenakth soldiers led by renegade, erstwhile Tenakth Marshal Regalla suddenly attacked the embassy, leading to many of the Carja and Tenakth representatives slaughtered, with Fashav and Nozar being victims. However, Aloy and Varl led a counteroffensive against Regalla's forces, thus stopping the rebels in the first place. Aloy was able to retrieve the Shieldwing from Grudda's possession.
===LATOPOLIS===
Aloy is soon granted the rite of passage to the Forbidden West, as she continued to reach No Man's Land, where she enters inside the Zero Dawn facility known as LATOPOLIS. From there she sees the degraded HADES imprisoned inside the module, who was interrogated by Sylens, before Aloy decides to interface into it. HADES, due to Sylens' torturous interrogation, was unable to extract any information to her, leading to her destroying the AI for good.
After creating Firegleam, Aloy enters inside LATOPOLIS, before coming across a recording regarding Tate and Sobeck's plans to stop the Zenith's thievery of GAIA, as well as with another audio log from Tilda van der Meer and Sobeck arguing from the same matter. She enters into the centre of the room, titled as RECLUSE SPIDER, where it housed many of GAIA's backups, but to her utter dismay only two of them were root kernels that had nothing on it. However, she later finds out that one of the functions, MINERVA, is seen around the mountains of the Utaru capital, Plainsong.
However, much to her utter anger, Sylens discloses the truth of her visit: To allow unwanted parties, revealing to be the Zeniths, to retrieve GAIA and rebuild it. Aloy soon destroys her spyware-ridden Focus, vowing to target Sylens as soon as she comes across him. However, a mysterious clone of Elisabet Sobeck, as well as three strangers enter the room, revealing to be Erik, Gerard and Tilda, who attempted to find GAIA on their own. However, the other clone accidentally revealed Aloy to the Zeniths, prompting Gerard to order Erik of disposing her for being an "unnecessary complication". A battle soon happened, but Aloy found herself to be outmatched against Erik due to his shielding that rendered him impervious. Aloy soon destroyed the RECLUSE SPIDER module, thereby allowing her to escape, but in the process she is thrown out of LATOPOLIS as she escapes through a flooded passage, landing her out.
===Zo and the Utaru===
Two days have passed, Aloy wakes up in the Utaru outpost of Stone's Echo. Varl arrived at her side and reassured her that the GAIA kernel was secure after hearing her wake. Aloy tried to stand up despite her wounds, determined to finish her goal, but Varl urged she talk to Zo, the Gravesinger who gave them sanctuary. The Utaru were performing a song in honour of Re, a Plowhorn that the tribe regarded as a "land-god," at that same moment. Aloy used her Focus to locate a broken component and remove it, which allowed the machine to rise to the pleasure of the Utaru.
Aloy soon revealed that the mountains where MINERVA is located is considered sacred to the Utaru, which required the permission of the tribe's government, the Chorus, but that all soon come to a head when her pleas were refused, in due to the fact that the tribe was on the verge of extinction. However, the Cordon was soon attacked by a group of machines, before Aloy, Varl and Zo go further into the mountains to reach Repair-Bay TAU, where it is revealed that Fa is being turned into a Grimhorn.
Realising that the once-docile land god is now hostile, Aloy and co. have no other choice but to dispatch it, much to Zo's shock as Fa's destruction led her to believe she doesn't know what to believe anymore. Aloy then decides to go with Zo's plans of saving her people. From there, HEPHAESTUS, now fully evolved, emerges from hiding, who is angered of her actions during the events of Frozen Wilds. Aloy then purges the rogue AI out from the Cauldron, thus overriding the core in the process.
===MINERVA and GAIA's Reboot===
Soon, the group head further into the facility, only for them to be stopped by the self-aware MINERVA. After Aloy reaches the centre room of the Regional Control Centre, she attempts to put the GAIA root kernel onto the console, only for MINERVA to hide the console out of fear, to Aloy's dismay.
Aloy proceeds to reason with the AI, before she subsequently manages to revert MINERVA back to its basic programming, thereby rebooting GAIA in the process. With the rebooted GAIA now functional, GAIA then tells Aloy regarding the missing subordinate functions, as well as the strangers she encountered inside LATOPOLIS and its relation to the Extinction Signal that was sent from the Zeniths' colony in Sirius to Earth. Much to Aloy's surprise, she already deduced that the Zeniths faked the Odyssey's explosion, as well as with the strangers wanting to steal GAIA to reboot the planet to their own desires, regardless of massive casualties.
Aloy then proceeds to retrieve AETHER, DEMETER and POSEIDON who were all scattered across the West in order to increase GAIA's heuristic matrix percentage to gain advantage against HEPHAESTUS.
===AETHER===
Under Hekarro's orders to convince Tekotteh and the Sky Clan to join the Kulrut in exchange of retrieving AETHER, Aloy soon personally confronts the Sky Clan leader, who refused her own pleas to side with Hekarro, due to his paranoia of Regalla attacking the Sky Clan capital.
After stopping a pocket of Regalla's rebels not far from the Bulwark, Aloy soon retrieves a Tremortusk cannon and decided to destroy the Bulwark's wall, thereby forcing Tekotteh to send his clan members to the Memorial Grove. She later stopped Regalla's first attack in the Memorial Grove, consequentially causing Hekarro to hail those who fought against the rebellion as new Marshals of the Tenakth.
Aloy soon opened the hatch below the server room next to Hekarro's throne and retrieved AETHER in the process. Upon retrieving the AI and reverting it back to its normal programming, AETHER's retrieval caused all the Visions in the Grove to change. One such Vision was with Faraday's speech, the Vision of Unity, which directly started the unification of the Tenakth, twenty years ago, as one and with Tekotteh changing his ways as he sides with Hekarro. In the process Kotallo soon joins in with Aloy's team in her efforts.
===Beta===
Later, as Aloy heads back to the Base, it is revealed that a mysterious signal hailing from ELEUTHIA was sent to GAIA under unusual circumstances, prompting her to investigate. Aloy is soon joined with Varl and Erend, despite her protests of going to the coordinates by itself, to visit the mountain where the data pulse was sent.
To Aloy's surprise, she, Varl and Erend spotted a Far Zenith known as Verbena Sutter fighting off a group of Tenakth rebels and rogue Oseram known as the Sons of Prometheus, before Sutter was soon killed when her shield was disabled by a mysterious device. Aloy and Varl soon enter inside the ruins of a Zenith research lab, before tracing the origin of the signal pulse from one of the ectogenic chambers. Inputting the number 237 that was seen from the message, the cradle soon opens, revealing the same Sobeck clone, known as Beta from earlier, warning her that the Zeniths have APOLLO, ARTEMIS and ELEUTHIA in their possession.
However, a pair of Specter Drones have attacked, forcing Aloy to dispatch them, but not before another one proved to be an issue due to its shielding. However, Aloy was able to also dispatch the machine, thereby allowing the trio to safely escape the machine threat. Then, she soon retrieves the weapon used by the Oseram rogues, revealing to be nothing more than a peculiar metal sphere, motivating her to investigate its origins to use it against Far Zenith.
Aloy brought the weapon to GAIA for research when she got back to the Base in the hopes that they could reproduce and enhance it to use against the Zeniths. It was similar to Zenith technology, but not in how it operated because a preprogrammed instruction erased all data the instant it broke down, according to GAIA. Both of them reach the conclusion that Sylens was responsible for the weapon's creation.
Then, Aloy soon talks to Beta by giving her a Focus, who revealed that Far Zenith managed to colonise Sirius, but was cut short because of a natural disaster. Aloy's initial remark of Zeniths being the descendants of the original colonists turned to shock, when Beta revealed that they were the same group of people who left Earth a thousand years ago, and made themselves immortal in the first place. Beta revealed to Aloy that she was a creation of the Zeniths, but she was only used as means to repair GAIA and only use it to destroy Earth and terraform it to their own liking, revealing her intentions to renege on them in the first place.
However, Aloy is soon stumped when Beta is soon thrown into a panic regarding Aloy's plans to use the machine army against the Zeniths, and with Aloy trying to calm down before she takes her leave.
===POSEIDON===
Aloy then continues her search of POSEIDON as she traverses to the ruins of Las Vegas. From there she encountered Morlund, Abadund and Stemmur, three Oseram delvers and show-goers who were attempting to search what seemed to be "Embers". However, she is soon come to a realisation that the Vegas ruins was submerged underwater, so she later crafts a Diving Mask from the items that she retrieved to traverse down the ruin. Traversing through the submerged city, Aloy soon manages to drain the city completely, thus allowing the Oseram trio to visit the ruin.
However, a Tideripper is seen prowling around, where Aloy soon dispatches it completely. Aloy then retrieves POSEIDON and reverts it back to its original programming. Attempting to reassure Beta again, who was watching Aloy's first datapoint, Aloy reveals more of Tilda from the Sobeck clone, as well as the Data Channel that the Zenith used to create. However, Aloy grew tired and frustrated of Beta's pessimism, deciding to leave her alone for now for the second time.
===DEMETER and the Quen===
Continuing on the search for DEMETER, Aloy heads to the coast northwest of the Base, only to find out that it is located within the ruins of a Faro research facility simply known as the Greenhouse. There, Aloy deals with a strange new tribe known as the Quen, who executes "barbarians" on the spot and was almost a victim by their indiscriminate attack in the first place.
Aloy then meets up with Alva, the Quen diviner searching for answers in her homeland, who later joins in on her quest to find one to save it from being driven to extinction. To Aloy's dismay, Alva sees her as Elisabet Sobeck's reborn. After finding the Vine Cutter module, as well as DEMETER, Aloy soon retrieves all of the needed Subordinate Functions, thus giving the GAIA the needed heuristic matrix percentage to stop HEPHAESTUS.
===The Omega Clearance and Thebes===
In spite of that success, however, Aloy is put into yet another realisation: HEPHAESTUS' heuristic density is considerably larger-than-normal to be beamcasted and with the rogue AI wiping itself out from Alpha Clearance. Realising that the only solution is Ted Faro's Omega Clearance, Aloy later heads to Legacy's Landfall, the ruins of San Francisco, to rendezvous with Alva and the Quen and head down to Faro's bunker known as Thebes.
Visiting Legacy's Landfall through a boat at the coast, Aloy soon ventures to the Isle of Spires during a stormy night, before subsequently reaching the Quen settlement at dawn, where she is met by the Quen overseer known as Bohai. However, their first meeting came to a heated tension, where Bohai soon threatened Aloy that either she is a threat to the Quen or Sobeck's reborn. Aloy confided that she was mistaken as a barbarian who was attacked by the Quen during her retrieval of DEMETER in the Greenhouse. The Ceo, Quen's leader, soon appears, thereby stopping the argument, where Bohai becomes more suspicious of Aloy and her intentions to visit Thebes would be the only way to save the world and the Quen from extinction.
With nothing else to lose, Aloy then plans to rendezvous with Alva who is currently at the digsite next to Thebes, but an Apex Thunderjaw soon stood in her way. She soon dispatched of the machine, which earned the respect of the Quen, before meeting with Alva and with Aloy being more and more uneased of her meeting with the Ceo and his plans to visit Thebes. Bohai and the Ceo soon arrived at the Digsite, where they reach Thebes' door, only for the door to be gene-locked by Faro, angering him. Aloy then visits the flooded passage to find an alternate route for Alva and the crew. In that moment Aloy heard the recordings of Kanya Somptow, one of the bunker's residents, and her disturbing experiences regarding Ted Faro's murders of Thebes' inhabitants including tech guru Grigori Fasbach and the rest with an "off-switch". Aloy then finds the door's emergency switch that opens the main entrance.
While Aloy is relieved of the door being opened, Aloy is forced to wear a complete replica of Sobeck's raiment, to her annoyance, when the Ceo soon threatened both her and Alva's lives should the Nora Huntress not comply. Reluctantly wearing the outfit, Aloy and the rest soon head through the abandoned bunker, where they enter the main hall, but not before two Corruptors, mistaken as statues, attacked the crew. Aloy is forced to dispatch the machines, before heading to the laboratory, where it is revealed that Narong Somptow attempted to give Faro life extension treatments, but mutations only made it impossible to happen. Ceo, meanwhile, disgustingly confided that Faro was still alive, with Aloy sarcastically remarking how he is the same as Faro for having self-deluded megalomania.
After seeing a jammed door in front of her, Aloy is forced to find another alternative route, before heading to Faro's room. She then finds a holographic module before downloading the Omega Clearance, as well as another audio log that came from Faro. From there it was revealed that the Somptows committed suicide, when Narong did so under his daughter Kanya's behest, where only Faro did not accept any blame for causing it in the first place. Aloy only remarked how he never changed at all, before voices soon come across from the generator room. Frightened, Aloy then uses the holographic module to reveal a horribly mutated Faro with little to no brain activity nestling within the reactor core, revealing that Faro went inside the room to mitigate the mutations, but only failed in the process.
The Ceo soon appears, who is disgusted to see Faro, ordering his own guards to burn his body, despite Aloy's warnings that it would trigger the safeguard protocol, which soon became true. However, the Ceo ordered both Aloy and Alva to be executed due to them being witnesses, forcing the duo to deal with Ceo's guards, before the two managed to escape the collapsing bunker and with the Ceo killed by the head of Faro's statue, putting an end to the madman once and for all.
Bohai and his group soon show up, where he personally questions Aloy and Alva regarding the Ceo's whereabouts. With Alva lying about the Ceo "dying" for secrets, Bohai sees through it and plans to execute both of them. However, Aloy soon convinces the Quen overseer, claiming that the Ceo died "like a gutless coward" for attempting to kill both of them to cover up his involvement under the rug and with her indeed finding something crucial that would save the Quen from being extinct. After much convincing, Bohai later welcomes Aloy to the Legacy's Landfall and with Alva joining in with Aloy's team, under the condition that she reports in on her efforts.
===GEMINI and the Rogue Zenith===
Rendezvousing back to the base, Aloy soon meets up with Beta, who warned her that while GAIA's transport rig was completed, the merge would take 35 hours, thus furthering the risk of Zeniths detecting them. However, revealing that GEMINI was the only machine cauldron with two cores on it, Aloy ideated the plan to merge HEPHAESTUS to GAIA with the help of Beta, thus significantly reducing the merge time to 4.5 hours.
But while that all seems to be a hopeful endeavour, Aloy is then thrown into another argument with Beta and her pessimism, who only feared that she would be recaptured by the Zeniths and subjected to their abuse again. Aloy then reassures Beta that Rost was the reason why she has the will to live and how his sacrifice during the Massacre that saved her life. Beta, thanks to Aloy's reassurance, finally joins in with her endeavour, but only she has to kill her should the Zeniths locate them inside GEMINI.
Aloy then leads the mission to GEMINI, before heading inside the cauldron, where they proceed with the merging process via the Omega Clearance. However, HEPHAESTUS soon shows up, proceeding to attack Aloy with its army of machines, but they proved to be no match against her as the AI escaped from another chamber. Aloy then personally sees HEPHAESTUS, who becomes grow annoyed of her interference, at the last chamber, where it sends a Slaughterspine to deal with her, but she still manages to destroy the machine for good, before proceeding to put HEPHAESTUS into the core for her and Beta excise any malicious code on it.
However, the plan soon came to a complete disaster when the Zeniths including Gerard, Erik and Tilda came inside, leading to a violent fight between both sides. Gerard incapacitated Aloy easily with his weapon and Erik managed to kill Varl with ease, before Erik soon captures Beta again. In a last-minute effort Tilda turned against Gerard and Erik, who unleashed a blinding Aloy, thereby saving Aloy from the jaws of death.
===Sylens' True Motivations===
Moments later Aloy later awakens, before being greeted by the sight of an abandoned building where she meets up with Tilda, revealing that the Zeniths have known of their plan beforehand to fool them. Aloy then hears more about the history of Far Zenith, as well as with the Zeniths forcing Beta to merge HEPHAESTUS to GAIA. 
Aloy hears from Tilda about all of Sylens' machinations, where she finds out that he strikes a deal with Regalla and uses her rebellion as means to overthrow the Tenakth chief Hekarro and attack Gerard's Zenith base, so that Sylens would use the attack as a distraction to take the APOLLO database and Odyssey to leave Earth for himself. However, Aloy knew how the plan is regarded as suicidal and would mean the end of all Tenakth, before insisting of an alternative. With Tilda revealing of a newfound plan to cripple Regalla's machine convoy, Aloy later deduces that she has to use the Sunwing override that Beta gave to her in order to retrieve a working EMP module from a Horus machine.
===Stopping Regalla===
Doing so, Aloy soon overrides a Sunwing, retrieves an EMP from the Horus and proceeds to fly as soon as possible into the Memorial Grove to avert Regalla's second attack on the Tenakth capital. She soon cripples the machine convoy with the weapon, immediately dashing all hopes of Regalla attempting to overthrow Hekarro, as Aloy manages to defeat the rebel leader in a battle, either killing her under Hekarro's orders or sparing her.
With the rebellions put down, Sylens emerges as a hologram, mocking her that her attempts of "stopping" the rebellion saved the tribe from extinction, but in doing so led to her world in process of being doomed. Unfazed, Aloy noted that she doesn't need an army to defeat the Zenith army and instead rendezvous with him and his weapon, as she came up with a plan without putting others at risk.
===The Attack of the Zenith Base===
Aloy soon encounters Sylens in the Base, meeting him in person for the first time since GAIA Prime, warning him that should he renege on him she would kill him, before Tilda is seen entering inside the facility. Sylens reveals to Aloy regarding the improvements he had done on his weapon, but not before she quells another argument between him and Tilda. Afterwards, Aloy and her team join in on the briefing on infiltrating the Zeniths' base, which was located on an island at an abandoned military facility, where Beta and GAIA are held at the launch tower. Aloy then tell Sylens to use his weapon against the Zeniths, should they appear.
After the briefing, Aloy then proceeds to order Kotallo and Alva to break through the Zenith network and find anything what Tilda has been hiding to the group, suspicions that Sylens have been having ever since meeting the rogue Zenith. Once Aloy and her team rendezvous to the beach close to the base with Tilda, they later head into the secret door that leads in to a tunnel that allowed her and the others to reach the base hidden from the Zeniths.
As they fight off against the Specter army emerging from the machine printers after Kotallo destroyed the reactor, HEPHAESTUS combat machines soon appear as they combat the machine threat, thereby giving Aloy and her team the advantage. But soon after, Gerard and the Zeniths emerge from the hiding, warning her that Tilda is a traitor to the Zeniths, as well as with him boasting how invulnerable he and the rest of the Zeniths are. But Aloy soon proves him wrong when Sylens managed to disable their shielding with his weapon, killing the rest of the Zeniths except him and Erik. Aloy soon reaches the launch tower.
Subsequently, Aloy soon reaches the elevator as Erik attacks her from behind, leading to a violent confrontation between tribal and Zenith. However, despite Erik's formidable weaponry, Aloy managed to defeat the Zenith military commander, before Zo soon stabbed Visser in the back, uttering his same words prior to killing Varl who avenged the death of his lover.
===Nemesis===
Aloy is forced to climb the tower after the elevator was disabled by Gerard, where she later receives message from Alva regarding "Nemesis", as well as escape vectors that were escape routes to Earth. After Alva's communication was abruptly cut off, Aloy finally reaches the tower and rescues Beta. Reassuring Beta again, Aloy tells her genetic twin to find out more about Nemesis, before they see a hologram of a mysterious red object chasing the Odyssey on deep space and how Earth was only used as a Zenith waystation, confirming that the Zeniths only wanted GAIA for their own purposes while leaving Earth at Nemesis' mercy.
After the revelation, the duo soon witnessed Gerard getting blasted off before Tilda kills him. Aloy, completely suspicious of Tilda, inquires her what Nemesis is truly is. Tilda then reveals that Nemesis is a failed digital storage project, in their botched attempts of digital immortality, which stored many of the Zeniths' minds. However, after the project failed, it was left imprisoned for decades, until Nemesis' hatred grew exponentially, swearing revenge against the Zeniths for abandoning it in the first place. This ultimately led to the rogue AI personally destroying the Zenith colony in Sirius in a matter of hours. In retaliation Nemesis sent the Extinction Signal to turn HADES into a rogue AI to destroy the remaining Zenith survivors. When the plan failed, however, Nemesis soon decided to chase the Zeniths in deep space. Tilda still wanted to carry out the original plan and realise Elisabet's wish by inviting Aloy to accompany her aboard the Odyssey so they could create a new home for humanity.
However, Aloy refuses Tilda's despicable pleas of abandoning Earth to a rogue, violent AI, with Tilda confessing that she regretted abandoning Sobeck on Earth, nearly a thousand years ago, and how she sees Aloy as a "superior version" of Sobeck's clone, thereby abandoning Beta. Aloy mocked her that no shielding would protect her, before Tilda summons a Specter Prime to personally deal with Aloy, once and for all. Aloy soon orders Beta to hide as she deals with Tilda in a final battle between machine and man. However, Aloy was able to defeat the rogue Zenith in a battle, thereby permanently ending the organisation in the first place.
Aloy soon heard the truth regarding how Sylens knew of Nemesis from HADES, as well as information needed to disable the Zenith's shields with his weapon and his plan to steal the Odyssey and APOLLO by using the Tenakth, in order to escape Earth for his own purposes. However, Aloy refuses Sylens' "invitation" to leave with him, who only argued that he instead joins the fight against Nemesis and put an end to the rogue AI's terror once and for all, instead of him leaving Earth to the AI's destruction. Sylens reminded Aloy how Nemesis destroyed a highly advanced colony in hours and the primitive Earth tribes would suffer the same thing. He recalled that Elisabet had to sacrifice her world in order for a new one to be formed and that, had Nemesis appeared, she would have abandoned the planet.
===The Future===
Despite that, Aloy simply refused his offers as soon as she regroups with her friends for a warm reunion. But to her surprise, Sylens had a change of heart who stayed on Earth for the time being, preparing for Nemesis. She later returns to the Base, remarking how her fight with Nemesis is more different than the one Elisabet faced during the Faro Plague and how she is no longer alone. She and Beta reactivated GAIA again, now with all of GAIA's seven subordinate functions included.
