Timeline of the Xenoblade Chronicles series

This is the history of the worlds of the Xenoblade Chronicles series, and the chronological order which events occurred.
== Klaus' world ==
*The Conduit is discovered in Africa by an unidentified scientist.
*The Coalition government forms the Aoidos institution to study the Conduit.
*10 years after the formation of Aoidos, it is learned that the Conduit acts a gateway between multiple universes.
*The Coalition government sets up three space elevators, "Beanstalks", on the equator (first tower Rhadamanthus, second tower Aeacus, third tower Minos). 
*The Orbital Ring is constructed atop the three towers, allowing the government to do further research on the Conduit away from the surface of Earth.
*A governing artificial intelligence collective known as the Trinity Processor is raised to maintain the Conduit.
*The Trinity Processor develops Artifices to protect the Orbital Ring.
*The Earthlife Colonization Project, also known as Project Exodus, sends a total of three million settlers out to the stars.
*The Saviorite Human Rights Protection bill is brought to congress during an unspecified summer month. The bill sparks a lot of public debate.
*A year later, at midnight on the sixteenth of an unspecified month, the first Rhadamanthus Spaceport launches the Icarus. The mothership is carrying 480,000 settlers to the in the of the .
*The Coalition government plans to send out ships nine to thirteen in the same year, each boasting a capacity of up to 1.5 million people. The ninth vessel is planned for departure in July.
*The 13 Authorities petition against the Saviorite Human Rights protection bill.
*Dimitri Yuriev, councilperson from the Minos Authority, issues a statement regarding the bill.
*A rebel group known as the Saviorites makes demands to the Coalition government to hand over the Conduit to them.
*At some point before the experiment, humankind were developing a material to replace human brain cells as a means of immortality. This would eventually become the basis of the Core Crystal technology used by Klaus.Xenoblade Chronicles 2, Memories of this Planet cutscene
*In 20XX, the First Low Orbit Station at Rhadamanthus tower is attacked by the Saviorites.
*The Beanstalk director attempts to initialize Aion to repel the incoming invasion, but fails to do so as they are locked out by Professor Klaus.
*Klaus syncs the Trinity Processor to the Conduit. Another scientist named Galea attempts to stop him, as it is too dangerous to conduct the experiment. She ultimately fails to change his mind, leading Klaus to initiate the experiment.
*The experiment causes a bright light to envelop Earth before vanishing and creating at least one new universe.
== Split era ==
The following two sections run in parallel, starting and ending at the same time, though it is unspecified whether the same amount of time passed between each.
=== World of Bionis and Mechonis ===
Some of the information in this section is only known from a chronology published in the Monado Archives, which has no official translation.
====Long ago====
* Half of Klaus, an unclear portion of Galea, and the Ontos core end up in a new universe. This Klaus believes his experiment has succeeded, and takes on the role of Zanza, a god of this new world. Galea becomes a second god, Meyneth, while Ontos takes on an identity as the overseer of the world.
* Zanza and Meyneth create two titans, the Bionis and Mechonis, and become their souls. They then create life to live on those titans: the Giants and High Entia on Bionis, and the Machina on Mechonis.
* The cultures of the two titans meet amicably.
* Egil and Arglas form a friendship.
* The cities of Alcamoth and Agniratha are constructed.
* Arglas finds the Monado, which allows Zanza to possess him and use him as a vessel. Zanza acquires disciples and forces the Bionis to attack Mechonis, ruining the Machina and causing a fight between the titans that "kills" them both. Defeated, Meyneth enters a long slumber, while Zanza's soul is split by the High Entia - sealing his body in Prison Island, and his soul (with the Monado) in Ose Tower. The remaining Machina take refuge on the Fallen Arm.
* Egil, looking for revenge, proclaims himself leader of Mechonis and decides to invade Bionis, killing Machina who oppose him.
* The High Entia, aware that Zanza may be released and transform them into Telethia, begin to research how to avoid this. Their theoretical solution is to cross-breed with Homs. They build systems to protect this knowledge and protect themselves from future attacks from Mechonis.
* Mechon begin to attack Bionis, and continue to do so for many years.
* The High Entia choose to ban the Bionite Order, which has been gaining popularity, though this is mostly ineffective.
* The Homs begin to establish colonies across the Bionis.The artbook claims the Homs are a "new race" at this point, but this contradicts the High Entia having already made a theory on crossing with them.
====Present time====
* Two people join a team of people who plan to find the Monado and use it against the Mechon. These two shortly give birth to Shulk.
* The expedition team finds the Monado. Zanza is awoken and steals the life of everyone there, including Shulk. Zanza takes Shulk as a vessel, effectively resurrecting him. Dickson shortly arrives to take both Shulk and the Monado to .
* Only Colony 9 and Colony 6 remain from Mechon attacks.
* Galahad Fortress is constructed, allowing the Mechonis to siphon ether from the Bionis.This contradicts the in-game implication that this siphoning has been going on for long enough that the High Entia think it's normal.
* The Battle of Sword Valley occurs. Dunban uses the Monado to seemingly wipe out the Mechon. Egil decides he needs to do something about this, and develops Face Mechon using the casualties of the battle.
* Shulk begins to study the Monado.
* The Mechon invade and occupy Colony 6. Many escape to a Refugee Camp. All who remained either die or are captured for Face purposes.
* Sorean, the current emperor of the High Entia, is provided a vision of the future by Alvis, the current seer of Alcamoth and projection of the Ontos core. This vision tells Sorean he will visit Prison Island and use whatever's inside (Arglas, unknown to him) against the Mechon, but die in the process. It also tells him that his daughter Melia will be involved.
* The Mechon raid Colony 9. Shulk discovers he can use the Monado. Fiora is killed.
* Shulk and Reyn head out on a journey of revenge. They meet Sharla and take back Colony 6, then Dunban joins them.
* Melia is tasked to kill an unusually powerful Telethia, and does so with Shulk's help. This leads to her undergoing further trials and being named successor to the empire.
* The Mechon attack Eryth Sea. Metal Face kills both Sorean and Arglas, allowing Zanza to fully reform within Shulk while also unshackling the Monado. Shulk discovers that Fiora is still alive.
* The party advances on Mechonis. They defeat Metal Face, lose to Egil, and discover the Machina. Eventually they confront Egil once more, after learning the truth of what happened to cause the titans to fight.
* Egil activates the Mechonis, and uses it to attack Bionis. Shulk defeats him before he can cause any real damage. Egil opens up the truth of Zanza and the Monado. Zanza takes the chance to ascend from Shulk's body, taking the Monado from Shulk, who he leaves for dead. In the end Zanza succeeds in destroying Egil, the Mechonis, and Meyneth, stealing Meyneth's Monado in the process.
* Zanza plunges Prison Island into the Bionis' head, causing an ether event that transforms all pure-blooded High Entia into Telethia. Half-blooded survivors scatter to other settlements.
* Shulk (not dead) and his team defeat Zanza's disciples before confronting him.
* Shulk achieves godhood, receiving his own Monado from Alvis.
* Zanza is defeated. At Shulk's decision, Alvis erases the world and creates a new one more in line with the physics and nature of the old world, with space and planets and saltwater oceans.
=== World of Alrest ===
Time Period 	Event
Near the beginning of the world. 	
* Half of Klaus ends up in either a second new universe or the remains of the original universe, along with the Logos and Pneuma cores. This Klaus sees that all other life has vanished to at least one other universe, believes his experiment has failed, and takes on the role of the Architect, choosing to try and recreate life.
* Klaus first creates a "special particulate substance with the ability to restore deteriorated matter" and uses it to take matter from Morytha. Inhabitants of Alrest come to know of this substance as the Cloud Sea.
* Klaus then combines the Cloud Sea, Core Crystals, and the pair of Logos and Pneuma to create a new cycle of life. Creatures known as Titans live in the sea and bear life upon them. This life bonds with Core Crystals to form s. As Blades bond, their Core Crystals exchange information about themselves and the world to Logos and Pneuma, who evolve them and send back new code to create further evolved Blades. After many cycles, Blades transform into Titans more evolved than their parents, in turn forming further-evolved life and more Core Crystals.
* The Conduit becomes silent after having been used in the experiment.
Significantly before TTGC. 	
* According to CHOCO in Alrest Records: KOS-MOS's and T-elos's Driver attempts to climb the World Tree. He fails and dies.Alrest Records page 14500年よりも遙か昔、 レックスともマルベーニとも違うひとりのドライバーが、 KOS-MOS Re: とT-elos Re: をエンゲージして世界樹登頂に挑戦し、失敗して死んだ。アルストの雲海に落ちていくふたり。
Many millennia later, when Amalthus is a small child. 	
* A young Amalthus and his mother are being chased by soldiers through a forest. His mother sacrifices herself so that Amalthus can escape. Later on, Amalthus finds the soldiers' camp and his mother's corpse. He kills the soldiers with a rock as they sleep.Xenoblade Chronicles 2, "Amalthus's Ambition" cutscene.
27 years before TTGC. 	
* Lora is born to Rynea.
17 Years before TTGC. 	
* A 10 year old Lora awakens Jin.Torna The Golden Country, "Jin and Lora's Resonance" cutscene.
When Amalthus is a young adult. 2 years before TTGC according to Minoth. 	
* Amalthus is acting as a Quaestor, spreading Indol's word and giving aid to war soldiers and refugees. He finds a soldier that he once helped has killed people to rob their home, and walks in as the soldier is about to kill a baby. Amalthus kills the soldier, and later on kills the baby, as he sees life on Alrest as a living hell and wants to spare the baby its suffering. 
* Minoth shortly finds Amalthus and is disgusted at this killing of the baby, leading him to part ways with Amalthus.Xenoblade Chronicles 2, "The World That You Intended" cutscene.Torna The Golden Country, "What Kind of Salvation?" cutscene.
Afterwards, still 2 years before TTGC 	
* Amalthus climbs the world tree in order to meet the Architect. He finds the Core Crystal of Logos and Pneuma and brings them back with him.
* Amalthus awakens Logos, creating the Aegis Malos.
Year 3564 	
* The 107th Indoline Praetor, Rhadallis, declares war on Coeia, whose capital Omrantha fell overnight.Torna The Golden Country, "Stinks Like Blood" cutscene In reality, it was Malos who sank it.
* Malos leaves Amalthus and acts on his own.
One year before TTGC. 	
* Amalthus, now promoted as a Quaestor, decides someone must awaken Pneuma to stop Malos. Zettar is unable to, but Addam succeeds, creating the Aegis Mythra. He sets out to stop Malos.
Sometime shortly after the sinking of Coeia 	
* The events of Torna ~ The Golden Country occur.
Right after TTGC. 	
* Addam goes to Leftheria to seal away the Aegis, while Lora's remaining group head to Spessia where Tornan refugees have gathered.
* Amalthus orchestrates a series of assassinations of Indol leaders, as part of a coup d'état to become Praetor. Stannif and Zettar are seen in Indol, presumably planning on establishing Tantal as a continuation of the Tornan royal line.
After Lora's group arrives at the camp. 	
* Amalthus attacks the refugee camp in Spessia. Lora is killed, and Jin becomes a Flesh Eater. Presumably this is when Mikhail is captured and taken to Indol to be experimented on, as well as how Amalthus obtains Haze's core crystal.
Not long after 	
* Jin sets in fire the two pictures of his old groups and Ornelia's house before bidding farewell to Azurda and takes the for himself.
Afterwards 	
* Malos, who have lost almost all his power, finds a depressed Jin in an alleyway in Mor Ardain. They team up and create an organization called Torna.
* Jin finds Akhos and Patroka being transported to Indol. They also join the Organization of Torna.
* Mikhail, who survived Amalthus' experimentations, is rescued by Jin and offers him join the Organization of Torna.
Year 4033The Driver in Ice 	
* Zeke is born.
Year 4043https://www.4gamer.net/games/368/G036837/20171130058/"The reason why Rex, a 15-year old boy, is able to show such fighting strength is because he is engaged with a Blade."15歳の少年であるレックスがあれだけの戦闘力を出せるのも，ブレイドとエンゲージしているからなんですね。 	
* Rex is born.
Between year 4043 and 4058Zeke left Tantal with 15 years, so this cutscene must happen around this time 	
* Zeke is saved by Amalthus, turning him a Blade Eater by injecting him half of Pandoria's Core Crystal.
Year 4045Enough Loss for One Life
:You know, Rex wasn't born here in Fonsett. He must have been two years old when he came ashore here with his poor mother. [...] She asked me to look after Rex, and... That was the last thing she said. She seemed so lovely, too... And his father... We found his body about three titanpeds away from here.	
* Rex and his parents flee to Fonsett Village, resulting on his parents' death
Between 4048 and 4058 	
* Nia's "sister" dies and her father makes her consume her body, turning into a Flesh Eater.
* Soon after that, her father dies and she resonates with Dromarch
* They become wanderers and are caught by Indol. Jin rescues her and offers her to join the Organization of Torna.
Year 4052 	
* Indol releases a map of Alrest, noting that there are currently 123 countries.Reddit comment by user "Boristus"
Year 4058 Well Met by Akhos Rex: What's the date today? Pyra: Um... Amathatober 5th, 4058. 	
* The events of Xenoblade Chronicles 2 take place.
Right after XC2 	
* The remaining Titans join together with newly-revealed land, forming a larger continent for the nations of Alrest to expand on.
== Intergame era ==
The following two sections run in parallel, starting and ending at the same time. While it is also unspecified whether the same amount of time passed between each, it is more likely that they are aligned compared to the previous section.
=== Post-Conduit Bionis ===
====Immediately====
* Shulk and the party celebrate a time of peace as the colonies rebuild.Fiora has her Homs body once again.According to the artbook story Back Home, the plan was for her to spend six months regrowing it. However, the scene as presented in-game implies it has only been a few days, not months.
* Shulk develops his own variation of the Replica Monado, the Monado Replica EX.
* About a year after the main game's ending, Shulk suggests ferrying Melia to the Bionis' Shoulder so they can investigate what has become of Alcamoth.
* They discover it has been taken over by an entity that locals call the Fog King and the Bionis' Shoulder is replete with Fogbeasts. Shulk upgrades his weapon into the Monado Replica EX+ and they manage to defeat the Fog King and subsequently the Fogbeasts. They reclaim Alcamoth, and the Bionis' Shoulder inhabitants are invited to join other settlements.Script of Future Connected
====Future====
* Shulk finds the Ontos core on a beach.
* Shulk and Fiora have a child, Nikol.
* Reyn and Sharla have a child, Panacea.Not technically confirmed, but very heavily implied via both lore tidbits and choice of Japanese voice actors.
* Melia becomes the master of Riku, one of Riki's sons.
=== Post-Conduit Alrest ===
* Fogbeasts appear on Alrest, presumably they are defeated by Rex and the party.Interview with Takahashi on Aionios Moments.
:For example, in Xenoblade Definitive Edition, the Fog King appeared on Shulk’s side. Looking at it from a different perspective, a similar phenomenon was occurring on Rex’s side. Just that this wasn’t portrayed.Unofficial translation.
* Rex has three children: Mio (with Nia), Glimmer (with Pyra), and an unnamed child with Mythra.
* Zeke and Pandoria have a child, Linka.
== Intersection ==
* It is discovered that the two worlds are approaching each other and will eventually collide, which would annihilate both worlds if left to happen naturally.
* Communications between the worlds are established. A plan is formed to defend against the Intersection.
* The two worlds each construct half of an enormous ark, Origin. Origin is designed to survive the Intersection and recreate the two worlds afterward, using its stored database of all things material and immaterial. The Bionis side of Origin is based on the discovered Ontos core.
* 300 days before the Intersection, Origin's construction is complete. Melia and Nia communicate to discuss this.Queen Nia's Story, Part 1
== World of Aionios ==
Time Period 	Event
Intersection 	
* As the two worlds collide, their planned recreation does not complete. Instead, an entity called Z either freezes or drastically slows time as a new world is created in their place, called Aionios.
Post-Intersection 	
* Z creates a faction named Moebius. They take control of Origin by having Melia be imprisoned.
* Melia creates the Lucky Seven and entrusts it to Riku.
* Moebius take control of Origin by having Melia be imprisoned.
* In the process, they design an endless war between two factions of continuous rebirth, Keves and Agnus, in order to feed themselves on life and death. A minority of people avoid being assimilated into these factions, and form the resistance movements of the Liberators.
An unknown time later 	
* The first City is constructed.
* Nia creates the Ouroboros Stone with the power of her Core Crystal and the key through which she accesses Origin.
* Nia hides from Moebius.This event is confusing, as Riku states in Future Redeemed that Nia hid not long after Melia was captured, but she interacts with Moebius M. A possible resolution is that she first hid somewhere no one in Aionios knows and later went to sleep in the Cloudkeep for better security.
Around 70 years before Future Redeemed 	
* One preincarnation of Noah and Mio have a child together, Ghondor.
* Several years after that, both Mio and Noah die and Ghondor has to live by himself.
Around 15 years before Future Redeemed 	
* Matthew and Na'el's parents die in in an attack on the City by Moebius.
Around 10 years before Future Redeemed 	
* The Ontos core goes rogue. Without Logos and Pneuma to guide it, it decides to erase Aionios and start a new world, regardless of Origin's original plans. To do so, it takes control of Origin from Moebius. Shulk, Rex, and Z confront the new instantiation of Ontos, Alpha. They lose and end up heavily injured.Creation of the WorldsThe Night Before
Shortly before Future Redeemed 	
* Na'el finds the Ontos core and Alpha reawakens within her
* Z becomes aware that Alpha is ready to take action in the City. He revives Noah and gives him a choice that results in him becoming N.
* Sometime around the above (possibly immediately after) but before the below: Z tells N he will revive Mio (as M) if he destroys the City and kills Alpha.
* While Alpha is taking action, N attacks the City and tries to kill a Na'el possessed by Alpha, but Ghondor gets in his way, and N kills him instead. In the process, Ghondor uses his Ouroboros power to cause a massive explosion of energy, helping destroy much of the City and seemingly causing A to be forked from Alpha. Matthew witnesses only the part where N kills Ghondor.
* A finds a half dead Matthew and heals him to full health. The two begin travelling together around Aionios to find City survivors and his sister Na'el.
Future Redeemed 	
* The events of Future Redeemed take place.
Right after Future Redeemed 	
* Moebius retakes control of Origin.
* Matthew leaves the City to start a journey while Nikol and Riku improve the Ourboros Stone. The preparations to found a new City begin at the Bannis Path, Great Sword's Base.
Sometime after the previous events (likely not long after) 	
* Nia gives the key of Cloudkeep to M and seals herself in the Cloudkeep so Moebius can't find her. The exact placement of this event is unknown; it could be shortly after Future Redeemed or shortly after the City destruction. In the relevant scene, Nia says to M: "You could throw yourself off, but it wouldn't be enough... Such is the fate of a Moebius. You should know by now." The "You should know by now" implies that she's been a Moebius for some time already.
An unknown time after 	
* M succeeds in changing the culture of Aionios to allow soldiers who live out their ten-year lives to die naturally, rather than be executed first. This becomes known as Homecoming.
* The Agnus Castle is moved from the Fornis Region to the north of the Cadensia Region and the Li Garte Prison Camp is built.
* The City is rebuilt on top of Swordmarch as a mobile Ferronis-like structure.
At least 1000 years after the first HomecomingSide Story: Noah	
* The events of Xenoblade Chronicles 3 take place.
Right after XC3 	
* With Moebius defeated, Origin is able to do its work. Matter originating from the two worlds begins to harmlessly pull apart.
* As the two worlds separate, there is a flash, and a third world becomes visible. The nature of this third world, whether it be a combination of the two, or something new entirely, is unclear. A blue streak of light descends from space, heading towards the newly created world.
==Events which take place at an unknown time==
* Nia meets with Mio at some point before the latter becomes M.To the Cloudkeep: "We've met before, when you were still human." This may have taken place either within or before Aionios; if it were within Aionios Nia would not have needed to remind M (as M has the memories of all of her preincarnations within AioniosJoran's Soul, D's Darkness), but it could have simply been a statement for the audience's benefit.
* The Monado Replica EX+, or an imitation of it, is put in a frame in the Queen's Chambers within Keves Castle. One possibility is that this occurs before Aionios, and Shulk's Blade within Aionios is another replica; another is that it occurs after the events of Future Redeemed, and the framed sword is indeed Shulk's Blade, which has been manifested within the Queen's Chambers via some unknown mechanism.
