Mondstadt/History

The timeline of historical events within the Mondstadt region.
==The Great War==
The term "great war" is derived from Neuvillette's Vision Character Story, which refers to a "great war of vengeance" which badly wounded the Heavenly Principles.
===Sal Vindagnyr (Dragonspine)===
* A group of people seeking refuge from a land of snow and strife find a bountiful and green mountain. They erect a monument on its peak and establish a civilization there, naming it Sal Vindagnyr, and the mountain Vindagnyr. Over time they built a large and extravagant castle on the mountain.
** Starsilver is an ore that is native to Vindagnyr, as the Snow-Tombed Starsilver was created long before Durin crashed onto the mountain.
* The civilization has a large white tree of great significance, and the princess is born under this tree. Her mother, the priestess, passes her blessings on to the princess, which include the ability to foresee events in the future.
* At some point later, the princess has a dream of Durin spreading poison upon the land. The people fear that this prophecy is a curse upon them.
* For some unknown amount of time, Celestia is moored above the mountain of Vindagnyr.
* The Skyfrost Nail descends from the skies, shrouding the city with clouds and snowstorms. One day, it shatters into three fragments, one of which turns the Irminsul tree into the Frostbearing Tree. The outlander Imunlaukr is living in the kingdom at the time, and the princess gives him a greatsword made of starsilver as he leaves to find answers. She promises to make a fresco for him, hoping to meet again.
* The princess is working on a fresco and her father, the priest, goes up the mountain for guidance since the trees are starting to wither. He hopes that the princess' third painting will be of melting snow, but unfortunately she's unable to finish the painting. The Skyfrost Nail splits in three pieces, then fragments further, releasing three orbs that freeze particular locations, including shattering the white tree. The princess takes the most complete branch and tries to graft it onto another tree, but it withers and she dies next to it. Someone else comes along trying to heal the leylines, but is unable to and buries the princess.
* Imunlaukr returns, finding everyone dead. He stores the greatsword made of starsilver among the frescoes and then goes off to fight in a war since he's decided Celestia only cares for bloodshed.
==The Interim Period==
While not formally established as its own period in time, Liyue lore indicates there was a stretch of peacetime between the Great War and the Archon War. 
===Old Mondstadt===
Note: Very little information exists about the region of Mondstadt before the fall of Decarabian's Mondstadt during the Archon War.Starts recording Mondstadt's history from the Age of Kings, which is the war between Boreas and Decarabian; whether the Northland Historical Society has any record of history before that is unknown. As a result, the order of events and information listed may be highly inaccurate.
* ? years ago ― An ancient civilization in the Windwail Highland area establishes Cecilia Garden, where they grew Cecilia flowers in greenhouses.
** Based on the architectural and ornamentation style of the ruins around Cecilia Garden, it may have been constructed by Decarabian or people from his civilization. However, there is currently no textual evidence of any link between Cecilia Garden and Decarabian's Mondstadt.
* ? years ago ― An ancient civilization at Starsnatch Cliff establishes the Sommernachtgarten. When the civilization fell, the Sommernachtgarten was buried underground and became Midsummer Courtyard.
* ? years ago ― At some point, Boreas, known as the King of the North Wind (or some variation thereof), gains his powers from an ancient god and becomes a god himself.
* ? years ago ― Decarabian establishes his capital city, Mondstadt, in the area now known as Stormterror's Lair. His territory expands to the Brightcrown Mountains and Windwail Highland areas, going as far south as the Teleport Waypoint between Dawn Winery and Stone Gate.
** Brightcrown Canyon was once filled with Decarabian's soldiers, guarding the entrance to the city. The city, meanwhile, was arranged in a circular formation around Decarabian's tower. Residents were assigned their own spots within the city.
** Decarabian's tower — which is already located in a very deep valley compared to the rest of modern-day Mondstadt and Liyue — extends even deeper into the ground. However, attempting to reach the bottom level of the aboveground portion of the tower results in an abrupt black screen, after which the player will find themselves on the wind current ledge above it and see unique out-of-bounds dialogue from Paimon: "Watch out! Don't go near there!"
* ? years ago ― The region of Mondstadt is filled with blizzards, turning it into an inhospitable wasteland. It is caused by Boreas, although whether it was intentional or not is somewhat ambiguous. To protect his city from the blizzards, Decarabian creates a storm wall around it.
==The Archon War (?–2000 years ago)==
===The Age of Kings (?–2600 years ago)===
* >~2600 years ago ― Boreas declares war on Decarabian, but fails to land even a scratch on Mondstadt. The war between the two Kings of Ice and Frost turns into a stalemate, and Decarabian's people begin to view his rule as one of despotism and tyranny.
** A boy only known as the Nameless Bard befriends a tiny, insignificant wind spirit that would later become Barbatos. The boy dreamt of seeing birds in flight, green grass, and the world outside the city.
** The clan now known as the Gunnhildr Clan once dwelled inside Mondstadt. However, Gunnhildr's father, the clan's leader, grew disillusioned by Decarabian's despotic control and led his people out of the city. Outside the city was only relentless cold and engulfing blizzards, however, and the clan struggled to survive. As they prayed for salvation, a wind spirit that would later be known as Barbatos responded to their prayers, as did Istaroth. The clan's faith in the spirit empowers it, granting it more powers that it uses to create a shelter for them.
** The first wines are brewed in Mondstadt when a certain mischievous wind spirit takes the form of a fox and ferments some apples under a negligent guard's care. When the guard awoke, he bit into one of those apples and, finding that he enjoyed the flavor, squeezed the sack that contained the apples to create wine. Also brewed in ancient times was a wine said to make a person forget the past, used so the people could have the strength to keep surviving.
** Inside Old Mondstadt, people who grew discontent with Decarabian's rule began planning a resistance. The "Windblume" was used as a code word amongst the resistance, with the Red-Haired Warrior among the first to use this codeword.
** Leonard the Adventurer invents the wind glider. His life goal is to scale Pilos Peak (now Musk Reef), but he fails his attempt and is forced to turn back. He writes the book "Of Mountains and Seas" as an account of his journey.
** Boreas realizes that his blizzards could not nurture life and decides that between his powers and his disillusionment with human society, he did not have the qualifications to become one of the Seven Archons. He chooses to allow his physical body to die while his powers flowed into the land of Mondstadt to nourish it. Despite losing his original physical form, Boreas' spirit remains extant and his powers are still strong enough that he can manifest a body of ice and wind.
* 2600 years ago ― Decarabian's people rise up in rebellion, led by the Nameless Bard, Barbatos (then known as the "elf" or "wind spirit"), Decarabian's former lover Amos, a knight (originally referring to the Red-Haired Warrior, now possibly referring to Gunnhildr), and the Red-Haired Warrior. The Gunnhildr Clan, led by its current namesake Gunnhildr, also participates in the battle. Decarabian is slain in the battle, as are Amos and the Nameless Bard. With Decarabian's death, Barbatos is elevated to godhood himself. He uses his newfound powers to create a vessel in the form of the Nameless Bard's, and takes up the bow in honor of Amos.
** The Red-Haired Warrior, for reasons unclear, turns his back on Barbatos and his name is eventually forgotten by the people of Mondstadt, though his deeds are still remembered. He eventually has a family that would eventually produce Ragnvindr and the Ragnvindr Family.
** Using his powers, Barbatos reshapes Mondstadt, using his winds to blow away the snow and ice covering the land and terraforming the region of Mondstadt in the process. Among the notable changes to Mondstadt's landscape was the eradication of Pilos Peak, which was turned into the modern-day Musk Reef. He then takes his people from Decarabian's old city and moves to Cider Lake, where they build the modern city of Mondstadt. Prominent clans among them are:
*** The Gunnhildr Clan, led by Gunnhildr,
*** The Imunlaukr Clan, whose leader at the time is unknown, and
*** The Lawrence Clan, led by Venerare.
** The Istaroth worked alongside Barbatos for Mondstadt's protection, and both were worshipped by the Mondstadters of old as the "winds of time," with the belief that "Anemo brings stories while Time nurtures them." However, at some point in time, the worship of the Istaroth as well as most records of them disappear and are forgotten.
* ? years ago, after the establishment of Mondstadt ― Seeing that his people had enough wisdom and strength to live on their own, Barbatos departs so he would not be able to become a tyrant.
** The Windblume Festival is established in memory of those who fought for freedom during Decarabian's reign. The codeword Windblume became conflated with literal flowers, while the festival became one about finding love.
==Post-Archon War==
===Mondstadt's Aristocratic Period (2600–1000 years ago)===
====Early Aristocratic Period (2600–1600 years ago)====
* <2600 years ago ― Dvalin, an elemental dragon, is born from pure Anemo energy located in the high heavens. The birth of an elemental dragon is a rare occurrence, and such dragons are equal in strength to the gods; historically, they have come to blows with the gods of old. However, Barbatos befriended Dvalin and the dragon became the first among the Four Winds to be worshipped by humanity.
* ? years ago ― The Hexenzirkel challenged Barbatos into a fight, but he refused and offered to resolve the conflict through song instead. From then on, they became allies, and Barbatos agreed to conceal one of the group's meeting place and its lantern.
* ? years ago ― Barbatos departs, and a class of aristocrats blessed with divine powers arose as leaders of Mondstadt. The clans in the aristocracy derived their lineages from heroes who lived during the early ages of Barbatos' Mondstadt. Known clans include the Lawrence Clan, Gunnhildr Clan, and Imunlaukr Clan.
** Venerare, leader of the Lawrence Clan at the time, built the Barbatos Statue in front of the Favonius Cathedral to commemorate Barbatos' descent. Beneath the statue was an inscription written by the leaders of the clans, pledging their defense of Mondstadt.
* During this time, the people of Mondstadt worshipped both Barbatos and Istaroth . However, at some point, the Istaroth and the worship of them were forgotten by the people of Mondstadt.
* Many of the festivals and customs in Mondstadt were enacted by the aristocracy for the betterment of the common people. Such festivities included:
** Hunting, a regular hobby of the aristocracy in which they worked alongside the common people and shared the spoils.
** Ludi Harpastum, a 15-day festival which celebrates the blessings of wine, song, and flight Barbatos bestowed upon the people of Mondstadt.
** Windblume, a festival that celebrates the Thousand Winds.
** Weinlesefest, a festival that celebrates the return of the Anemo Archon when the west wind blows every fall during the harvest season.
* 2600–500 years ago ― The incident known as "The Tyrant's Final Fury" occurs.
** For about one year, the first Field Tiller shot missiles from Stormterror's Lair at anyone who approached. The first Field Tiller had wandered into the abandoned tower of Decarabian after being damaged by Lupus Boreas, who mistook it for a challenger when it wandered into his arena.
====Late Aristocratic Period (1600–1000 years ago)====
* ? years ago ― Ursa the Drake starts terrorizing Mondstadt.
* ? years ago ― The Lawrence Clan became the foremost clan in Mondstadt and became the main rulers of the city. However, they grew corrupt and fell to degeneracy, eventually becoming tyrants who enslaved and tormented the common people while viewing themselves as overlords and kings.
** The Gunnhildr Clan allegedly maintained its honor, but were less influential than the Lawrence Clan which ruled Mondstadt. The status and fate of the Imunlaukr Clan are unknown, while other clans among the aristocracy followed the Lawrence Clan's lead.
* ? years ago ― The aristocracy used various methods to control the people and keep them ignorant. Anyone who posed a threat to their reign was enslaved and used for labor or entertainment; knowledge of the past was suppressed, and cultural and historical relics that would point towards the truth were taken down.
** The knight order at the time, who referred to themselves as the "starlit knights," served the aristocracy and upheld its degeneracy, using their strength to oppress the commoners.
** The royal mages no longer instilled virtue in the nobles, and instead helped them keep the people ignorant. The Church also used their influence to justify the aristocracy's actions and keep the commoners from realizing the truth.
** The Church of Favonius suffers a schism, with the higher-ranked clergy backing the nobility.
* >1010 years ago ― Vennessa and her younger sister Lind are born into a nomadic tribe of the southern plains, exiled from its homeland for reasons unknown.
** 1010 years ago ― After running afoul of Ursa the Drake and being starved by the dragon over the course of several days, she and her people flee to Mondstadt, only to be enslaved by the aristocracy. Because of her great strength, Vennessa was made into a gladiator, bound by chains. The chains themselves could not bind her; as a child of Murata, Mondstadt's ordinary-quality ores and lack of her homeland's divine flame meant its metals were nothing before her strength. What kept her subservient was her responsibility to her people.
* ~>1000 years ago ― Eberhart, an illegitimate heir to Landrich's clan, was a particularly manipulative and ruthless figure who lived at the end of the aristocratic era. He grew up in a noble home with his older half-brothers, Parsifal and Ingbert. Due to his illegitimacy, he was never looked on the same way as his older half-brothers which bred discontentment within Eberhart. He also knew how far the aristocracy had fallen from its golden days and sought to restore the ancient aristocracy's glory. To this end, he used his cunning to become a key figure in the aristocracy's downfall.
** ? years ago ― Eberhart goaded his older half-brother Parsifal's love of chivalry and play-acting, convincing him to become a Phantom Thief, then deceived him in some unknown manner, forcing Parsifal to flee Mondstadt and removing him from the line of succession.
*** During the late Aristocratic Period, spears and polearms came to be viewed as weapons used by lowly commoners and slaves, likened to gladiators' weapons compared to the noble and elegant sword. However, Eberhart secretly trained to use one in order to overthrow the aristocracy, and even became the disciple of the witch who created the Crescent Pike, using her love for Parsifal to get close to her before discovering her weakness and killing her. It appears that he took up the lance to gain an element of surprise against Ingbert, a Vision user, who would have easily bested him in combat otherwise.
* >1000 years ago ― The Wanderer's Troupe is established, comprised of people from all over Teyvat. It was both a musical troupe and a militaristic troop, gaining the moniker "Swordsman's Troupe" as they traveled throughout the continent. At one point, they faced an unknown foe in the Mare Jivari, and they made their final stop in the City of Mondstadt. They tried and failed to overthrow the aristocracy, and most of its members were slain during the battle, enslaved afterwards, or fled. Known members include:
** The founding member was the Conductor who wielded The Widsith, a collection of the Troupe's travels and musical compositions. He was slain in battle.
** The Sojourner, also known as the harpist and lyrist, who wielded The Stringless. He hailed from Fontaine and left his home country in search of his true fate. He was the second member of the Troupe, having met the conductor by chance. He fell in love with a Mondstadt girl, only for her to be chosen as the Ludi Harpastum princess — which meant she would be claimed by a member of the Lawrence Clan. In the attempted rebellion, he lost his life to protect his allies.
** The Dawnlight Swordswoman, also known as the sword dancer, wielded The Flute and was the third to join the Troupe. She was enslaved after the attempted rebellion and turned into a gladiator, where she ultimately met her end. Even while enslaved, she sang of freedom and openly questioned the aristocracy's reign and the people's acceptance of their rule. Her interactions with Ragnvindr inspired him to rise up against the aristocracy, and he adopted her epithet in his title, "Dawn Knight."
** Kreuzlied, who abandoned the Lawrence Clan, was the fourth to join the Troupe. He wielded The Bell and is the only known survivor of the Troupe, spared because of his lineage. Despite the Troupe's disbandment, Kreuzleid did not give up resisting the aristocracy; he established an underground organization, which would remain active even 500 years later, and used it to aid Vennessa's rebellion.
*** 500 years later, it was secretly used by Rostam to aid the Knights of Favonius from the shadows. It is unknown whether the organization is still active in present day.
* ? years ago ― After many years of loyally fighting under his master Eberhart, the Gladiator who wielded the Deathmatch (and who the Gladiator's Finale set belongs to) meets his end at Vennessa's hands. Despite fighting many bloody battles for Eberhart's and his own glory, even after he had already won his freedom — having been manipulated by Eberhart into continuing — the Gladiator finds that Eberhart had already left the scene for reasons unknown.
** ~1000 years ago, after the Gladiator's death ― Landrich organizes an aristocracy-led expedition to Sal Vindagnyr, hoping that the expedition will be a great success and their achievements will quell those hoping to rebel against the aristocracy. The expedition party included Ingbert, Eberhart, Luther, Nick, and several other promising young aristocrats. However, the expedition party never returned, so documentation on the event is sparse.
** Sometime after arriving at the mountain, the team gets caught in a snowstorm and the unnamed members get separated from the others, who meet up at the South Base Camp. Eberhart convinces the others that the unnamed members should be able to find their way back to the camp, and additionally persuades them to investigate a secret room that supposedly contains frescoes and weapons forged from starsilver.
** Not only are they unable to open the locked door of the secret room, but a cave-in kills Nick, burying his supplies with him. Returning to the South Base Camp, they notice the unnamed members have still not returned and Luther hopes they made it back down the mountain to get help. They decide to return to the original plan of exploring the cellar in the southwestern ruins once the storm dies down a bit.
** Eberhart leads Ingbert and Luther into the cellar and then takes out a polearm, striking Ingbert first and trying to kill them both. While he gravely injures both, Ingbert uses his Vision to launch a counterattack, forcing him to retreat heavily injured. While bleeding out in the cellar, Luther realizes Eberhart's large-scale scheme, writing down an apology to Priscilla before leaving a message for whoever reads the journal to warn Landrich.
** After leaving the cellar, Eberhart takes refuge in an area where a prison used to be and plans to follow the waterway to where his supplies are hidden. Either at the prison or between there and the supplies, Ingbert catches up to him and Eberhart manages to kill him. Eberhart then heads east to reach the sea and finds his boat and more supplies untouched. He then leaves for Mondstadt with the knowledge that if news reaches the city, Priscilla — who unbeknownst to Luther, was one of Eberhart's co-conspirators — will warn him by lighting a torch at Stormbearer Point. However, there are no records of Eberhart's return, leaving his ultimate fate a mystery.
*** Eberhart's boat never reaches the shore and the waiting Priscilla gets caught by the nobles after the plot is revealed.
===Mondstadt Reborn (1000–500 years ago)===
* 1000 years ago, after Ludi Harpastum ― The prayers and cries of the oppressed awakens Barbatos from his slumber, and he descends on Mondstadt under the guise of Venti. He befriends Vennessa after she raised the ire of Barca Lawrence, the heir to the Lawrence Clan, and was sentenced to undergo a series of gladiator matches to win her and her people's freedom. Her last battle is against Ursa the Drake itself, as Lord Lawrence had bartered with the evil dragon to give Mondstadt peace with her and her tribe as an offering. At this moment, Barbatos descends on the battlefield and reveals his true form, giving Vennessa the power to prevail against Ursa and freeing the people from the aristocracy's villainy.
** The above is the official history recorded by Mondstadt's historians. However, this was the beginning of a longer rebellion, during which Barbatos forged a contract between the aristocracy and Morax, claiming that the aristocrats had sold all of Mondstadt to the Geo Archon — including their own troops. After it was discovered, this "treachery against the wind" caused the troops to rally against the aristocracy, hastening its end. Only many years later did scholars discover that this treaty was fake.
** Ragnvindr and Kreuzlied are among those who assisted Vennessa's rebellion, as were adherents to the Church of Favonius mobilized by the Nameless Shepherd. It is unclear whether the rebellion Eberhart intended to assist when he sabotaged the Dragonspine expedition was Vennessa's, or if it was a different one that was being plotted around the same time.
* After Vennessa's rebellion succeeded, most of the aristocracy and those who had collaborated with them, such as the royal mages, are exiled from Mondstadt. Those who proved themselves uncorrupted, such as the Gunnhildr Clan, were allowed to remain.
** Vennessa establishes the Knights of Favonius, with herself as its first Dandelion Knight and Grand Master, and restores the Church of Favonius to prevent tyrants from taking over Mondstadt again.
*** After the Knights of Favonius was established, a certain Knight of Boreas arrives at Mondstadt and joins them. However, the wolf companion he originally journeyed with chose not to follow him into the city, preferring the wilderness. The two continued to fight together whenever the Knight left the city to hunt or do battle. When the wolf dies of old age, the Knight buries it in the remote countryside and leaves the Knights of Favonius to become a wanderer.
** Ragnvindr converts the aristocrats' indoor bathhouse into the original Mondstadt Library. It would eventually become the largest library in all of northern Teyvat, up until the Great Fire of Fall Equinox reduced it to one-sixth of its original size.
*** The Barbatos Statue, which was originally erected by Venerare but taken down by the late aristocracy, is also restored, though the original inscription on it has been lost.
* ? years ago ― The Four Winds are established, with Boreas as Wolf of the North and Dvalin as Dragon of the East. Vennessa was simultaneously the Lion of the South (as the first Dandelion Knight) and Falcon of the West.
* ? years ago ― Vennessa is chosen by the gods and ascends to Celestia at Windrise. A massive oak tree grows where she stood when she ascended.
** This tree has a mysterious connection to Celestia; Venti channels power from it to purify himself from the Abyss' influence, as well as to heal his body after getting his Gnosis forcefully taken by Signora.
* ? years ago ― The Great Fire of Fall Equinox reduces the Mondstadt Library to one-sixth of its former size. However, the contents within the library's restricted section, located behind the poplar doors in the library basement, were left untouched.
*? years ago ― Boreas and his wolf pack did not originally live in Wolvendom, but moved there at an unknown point in time. It is unclear whether the Temple of the Wolf, located near the Thousand Winds Temple, formerly housed Boreas' spirit.
==Pre-Cataclysm (>500 years ago)==
* >500 years ago ― Arundolyn, Rostam, and Rosalyne-Kruzchka Lohefalter are born.
* >500 years ago ― Arundolyn and his childhood friend Rostam grow up together in Mondstadt and eventually both join the Knights of Favonius. Arundolyn becomes the Grand Master known as the "Lion of Light," while Rostam becomes the "Wolf Pup."
** Rostam gained the title of Wolf Pup when he was 27 years old. He preferred doing dirty work in the shadows, without restraints of being a knight, so that Arundolyn could remain a model knight. It is said that he continued running the secret society established around 500 years earlier by Kreuzlied.
** Rostam taught the Knights of Favonius his sword style, the Favonius Bladework, which continues to be used to this day. Arundolyn's fighting style, which wielded a greatsword in one hand and a longsword in the other, required immense strength that few were able to replicate, and so it soon died out.
* >500 years ago ― Rostam and Rosalyne-Kruzchka Lohefalter fall in love.
* >500 years ago, just before the cataclysm ― Rosalyne leaves Mondstadt to study at Sumeru Akademiya.
==The Cataclysm (500 years ago)==
* During the cataclysm, The Knights of Favonius, led by the current Grand Master Arundolyn and Rostam, go on an expedition to Khaenri'ah to fight the monsters.
** Rostam mentors a man known as the White Knight (possibly "Roland" who loved justice above all else and fought against the monsters of Khaenri'ah. As he fought monsters, he came to be known as the Bloodstained Knight, and people started fearing him. He then ventures deeper into Khaenri'ah and dies battling monsters. In the depths of the world, he learns about the origin of the monsters that destroyed Khaenri'ah and the ultimate injustice that turned the people of Khaenri'ah into monsters, therefore joining the Abyss Order.
* An alchemist from Khaenri'ah, "Gold" Rhinedottir, creates one of her masterpieces, Durin. She sends Durin and other creatures she created to the continent of Teyvat to "display [their] beauty." Upon reaching Mondstadt, however, Durin lays waste to the city, although it is suggested that Durin was not conscious of his actions after reaching Teyvat until Dvalin fatally wounded him in their battle.
* At that time there was no Lionfang Knight, as Arundolyn, then Grand Master of the Knights of Favonius and Lion of the South, gave up fighting after his friend Rostam died during the expedition to Khaenri'ah. As a result, there was also no one strong enough to take on Durin.
* The people's cry for help are heard by the Anemo Archon, who calls upon Dvalin. The two engage Durin in battle and eventually defeat him, but Dvalin ingests Durin's poisonous blood, corrupted by the Abyss' power, in the process. To recuperate, Dvalin takes refuge in Decarabian's Tower in Old Mondstadt and falls into deep slumber.
** Durin's corpse falls over on Dragonspine and the power inside Durin's blood seeps into the land, reviving the Frostbearing Tree. Durin's blood appears to coagulate as Scarlet Quartz, due to the high concentrations of the mineral in Wyrmrest Valley, wherein Durin's heart still beats.
* Rosalyne-Kruzchka Lohefalter returns to Mondstadt and learns of Rostam's death. In her rage and despair, she uses the art of liquid flame she learned at Sumeru Akademiya to turn her body into that of living flame to avenge him, and becomes known the Crimson Witch of Flames.
==Post-Cataclysm (500–100 years ago)==
* ? years ago ― Before the Crimson Witch of Flame could be fully devoured by her own flames, Pierro of the Fatui Harbingers, finds her and recruits her, giving her a Cryo Delusion to put out her flames. The Crimson Witch of Flame becomes Signora, the 8th of the Fatui Harbingers.
* 400 years ago ― An ancestor of Ella Musk and Dr. Edith writes "An Investigation into the Cultural Customs of the Wind Kingdom," which is excerpted in Breeze Amidst the Forest.
* >300 years ago ― Olaf, a denizen from Springvale, is born.
* 300 years ago ― Olaf is frozen by a Cryo Regisvine while attempting to hunt a certain breed of boar, prized for its extraordinarily sumptuous taste, that is driven to extinction everywhere except for Dragonspine. According to stories passed down during his time, Springvale was formed around a spring created by melted ice and snow from Dragonspine, so it was established after Sal Vindagnyr froze over.
* <200 years ago ― A Lochfolk named Callirhoe, also known as the Spring Fairy, moves to Springvale from Fontaine and blesses the waters. According to Olaf, there were no stories about the Spring Fairy during his time, indicating she probably arrived after his accidental cryopreservation. 
==Recent Past (<100 years ago)==
Note: The bullets below are arranged in order of relative reverse chronological order, estimated based on characters' apparent ages.
*? years ago ― One of the statues of the seven in Mondstadt goes missing over night having been stolen by the Abyss Order for their Loom of Fate operation.
* 50–40 years ago ― Amber's grandfather, a renowned mercenary leader from Liyue, falls victim to a disastrous monster attack that leaves him the sole survivor. After being saved by a doctor from the Knights of Favonius, he decides to move to Mondstadt and become a member himself. There, he established the Outriders, a division of archer scouts whose members he personally trained. He also starts a family there.
* ~50 Years Ago ― Callirhoe, also known as the Spring Fairy, strikes up a friendship with Old Finch when he is a child. Their story becomes the basis for the book, Heart of Clear Springs. 
* ? years ago ― The famous adventurer Seamus Pegg decides to settle down in Mondstadt, joining the Church of Favonius and eventually rising to the position of Cardinal of Daybreak. He also falls in love with Frederica Gunnhildr of the Gunnhildr Clan.
** ~25–15 years ago ― Seamus and Frederica have two daughters together, Jean and Barbara. Some years later, the two lovers have a falling out and separate; Jean stays with Frederica, while Barbara goes with Seamus.
* 12 years ago ― Diluc receives his Vision at age 10.
* >10 years 6 months ago, end of summer ― Kaeya is abandoned by his biological father near the Dawn Winery as part of an "ancient plot," presumably to save Khaenri'ah. Crepus finds him and takes him in, raising him alongside Diluc.
* 10 years ago ― Frederica prepares strict training regimens for Jean, which continues to influence her habits long after she became a member of the Knights of Favonius.
* 8 years ago ― Diluc becomes the Cavalry Captain of the Knights of Favonius at 14 years old, making him the youngest-ever holder of any captaincy within the Order.
* Jean is conferred the title of Dandelion Knight at 15 years old.
* On the night of Diona's seventh birthday, she is blessed by the Spring Fairy of Springvale with the ability to make delectable beverages, no matter the ingredients.
* April 30, 4 years ago ― On Diluc's 18th birthday, Crepus Ragnvindr dies after using a Delusion to protect his and Diluc's caravan from Ursa the Drake, which was lured to them by the Fatui using metal bugs that emit the aroma of Mist Grass. Afterwards, Eroch, an inspector within the Knights of Favonius, orders that the cause of Crepus' death be covered up to maintain the Knights of Favonius' dignity, attributing Ursa's retreat to Diluc while labeling Crepus as a victim of the monster attack. In a fit of rage, Diluc resigns from the Knights of Favonius and abandons his Vision to investigate the truth behind Delusions for himself.
** Details on Crepus' death are left ambiguous in-universe: Diluc's character stories and one of Kaeya's character stories say the power of the Delusion backfired and killed Crepus, but according to Kaeya's Vision story and his description of Diluc in the manga, Diluc personally killed Crepus to spare him the suffering caused when the Delusion backfired. The manga's flashback is ambiguous and can favor either interpretation.
** On the night of Crepus' death, Kaeya reveals the truth about his origins and purpose to Diluc. In the ensuing fight, Kaeya gains his Vision.
** Shortly after Crepus' death, the Fatui use the metal bugs again to lure out Ursa the Drake so Il Dottore can slay it, forcing Mondstadt to be indebted to the Fatui and giving them leverage in the city's affairs.
** Diluc journeys across Teyvat to seek the truth behind the Delusions. He discovers that the Fatui are behind them and, in the process of finding out more, lays waste to countless Fatui strongholds. Unable to ignore this threat, the Eleven Fatui Harbingers set up a trap for him and nearly kill him, but he narrowly escapes due to a "third-party observer from the north." This observer is part of an underground network which Diluc joins.
* 4 years ago, after Crepus' death ― Amber's grandfather abruptly resigns from the Knights of Favonius and disappears, leading to rumors that he had defected. Amber joined the Outriders as a trainee shortly before this, and watches as the division crumbles in the absence of its leader.

* After two years of study at Sumeru Akademiya, Lisa graduates. Disillusioned with the atmosphere there, she returns to Mondstadt and joins the Knights of Favonius. Grand Master Varka sought to promote her to Captain of the 8th Company immediately, but this notion was opposed by its Field Officer, Nymph. After a field test, Lisa decides to take the position of Librarian instead so she wouldn't have the responsibilities of captaincy.
* May 28, ? years ago ― Fischl gains her Vision the moment her 14th birthday is over. Shortly afterwards, she becomes an investigator at the Adventurers' Guild despite her young age thanks to her Vision and her parents' influence.
*Razor meets Varka, the current Knight of Boreas, when the man visits Wolvendom one day. Varka gives him his name and teaches him how to use claymores, but embarks on his expedition before ever giving Razor his own name.

* ~3 years ago ― Rhinedottir and Albedo discover an artifact called The Heart of Naberius within the heart of a dungeon in an unknown region. Shortly thereafter, Rhinedottir disappears, leaving Albedo only a note instructing him to uncover the "truth and meaning of this world," a recommendation letter to give to her friend Alice, and a part of the classical text Opus Magnum. After finding Alice, Albedo is sent to the Knights of Favonius, who could supply him with a laboratory with which to conduct his research. There, his prowess in the Art of Khemia, a yet-unseen art in Mondstadt, lands him the position of Chief Alchemist.
* 6 months ago ― Grand Master Varka takes the elites of the Knights of Favonius, as well as the cavalry, with him on an expedition away from Mondstadt, appointing Jean as Acting Grand Master in his absence. Seamus Pegg, Frederica Gunnhildr, Mika, and Godwin are among those who went with him, though Godwin was left behind when he took the time to look for Glory's good-luck charm that he misplaced.
** After Varka's departure, Diluc returns to Mondstadt, taking over as head of the Dawn Winery that he had entrusted to Adelinde and Elzer and taking up his Vision once more. Around this same time, a mysterious entity who becomes known as the "Darknight Hero" appears, prowling Mondstadt at night and fending off threats to the city. Unbeknownst to most people, this hero is Diluc himself.
* A thief steals an artifact from a certain eastern temple in Mondstadt, a vial supposedly containing Barbatos' breath. After word got out, counterfeits have flooded the black market and since then, Diluc and the Fatui have been in a purchasing war in their attempts to each secure the genuine artifact.
* Last Ludi Harpastum (~1 year to 6 months ago) ― The events of the manga's main story occur.
** The Fatui, led by Il Dottore, attempt to take of Ludi Harpastum to recruit more test subjects, but are thwarted in their initial attempt by Diluc and Kaeya's plan, and Dottore loses interest in the city. As some Fatui diplomats are about to leave on Dottore's orders, they run afoul of Collei, who needed a distraction to slip into the city. She uses the power of her Archon Residue to create a serpent of black fire that kills the diplomats, and the Knights of Favonius are obligated to investigate the situation to maintain relations with the Fatui.
**Collei, seeking information about Barnabas to exact her revenge, runs into Amber, then Jean and Lisa. They give her permission to enter the library as they continue investigating the Black Fire Incident, and discover that the power that slew the diplomats is similar in nature to the Delusion (Evil Eye) used by Crepus several years earlier. Amber, who had encountered Dottore as he departed from Mondstadt, grows suspicious after noticing that both he and the Delusion smelled of Mist Pollen. She decides to try and track him down, and manages to find a Fatui device inside a hilichurl camp. However, she is then attacked by Krupp, a former Fatui researcher whom Dottore transformed into a Ruin Hunter. Together with Jean, who went to reinforce her, they take down Krupp for good and return to Mondstadt with evidence against the Fatui.
** Realizing that the Fatui are hoping to instigate a swarm of monster attacks during the festival so they can take the credit for defeating them and saving Mondstadt, the Knights of Favonius decide to track down the Fatui devices and destroy them. In the meantime, Lisa contacts her teacher at Sumeru Akademiya to see if anyone would be able to seal Collei's Archon Residue. Amber takes advantage of the situation to let Collei experience Ludi Harpastum's festivities, but their fun is interrupted by Kaeya, who lures Collei away and attacks her to draw out her powers, confirming that she was behind the Black Fire Incident. Upon realizing that Collei herself is innocent, and Amber's interruption allowing her to get away, Kaeya decides to enlist Diluc's help in creating an alibi for the girl.
** Barnabas, who came to deal with the Black Fire Incident in Dottore's stead, confronts Kaeya about Collei, having witnessed Amber help her escape. Kaeya pretends to help, with Diluc posing as the perpetrator behind the incident to Barnabas' guards. However, Barnabas himself notices the archon power emitted when Cyno — who was sent from Sumeru Akademiya in response to Lisa's message — seals away Collei's Archon Residue. He confronts and attacks Collei and Amber after Cyno leaves to report to Lisa, but is eventually thwarted by Amber and Diluc's efforts.
** Kaeya "traps" Diluc after Barnabas' defeat, allowing the Fatui guards to arrest him and take him away, thereby absolving the Knights of Favonius from any responsibility. Shortly thereafter, Diluc breaks out, leaving behind his mask and Delusion for an uninterested Dottore. The Harbinger also grows irritated by Barnabas' failure and has his guards get rid of him.
*** In the manga, Kaeya returns Diluc's Vision after he breaks out of prison, hiding it inside the Strange Vase that can be seen inside the Dawn Winery in-game.
