Arknights Timeline

This article is about the timeline of lore events. For the timeline of in-game events, see Story/Movements.

The following page chronologically lists and summarizes the notable events of Arknights, including crucial historical and story events.

Note that any event with an estimated or unconfirmed date will be labelled with "ca." (circa).

"Predecessor" Era

Long ago, around 12,000 BCE, there existed a race known as the "Predecessors", an advanced civilization who had mastered advanced technologies and interplanetary travel. Their existence is only known to a few.

• Creation of DWDB-221E: A team of Predecessors create DWDB-221E—also known as the Black Crown or Civilight Eterna—with the goal of leaving a repository of civilization's knowledge for later generations.
• The AMa project: Priestess and Oracle eventually create Ama-10, who would later be named Kal'tsit by Oracle.
• Creation of the Stargates and their eventual malfunction, leading to the invasion of the Collapsals
• "Disaster from Above": The Predecessors were largely wiped from existence due to the "threat" from above. Only their creations remain.
  • Formation of the Starpod: The Starpod is created in an attempt to shield Terra from the Observer threat, encompassing Terra and preventing its denizens from seeing the true sky. The Starpod's creation marks the end of the Predecessors, and the beginning of those who will eventually call Terra home.
• The Firstborn project

Before the Common Era

Many of these events happen following the collapse of the Predecessors and the rise of new civilizations. These events are said to have happened thousands of years ago; thus, they will be presumed to have occurred before the Common Era.

• Foundation of Kazdel (~10.000 BCE): An exiled Teekaz hunter finds Civilight Eterna and the Amnannam in the Silver Mountain range. Exposure to these two forces lead to the physical and mental evolution of the hunter to the eventual approximate of a human. This hunter became known as the "Farchaser;" The first King of Sarkaz and founder of the first Kazdel.
• The Descending War (9000~8000 BCE): At some point after the city-state of Kazdel is built under the Farchaser's guidance, the Ancients and Elders begin making contact with and attacking the Teekaz, who retaliate in self-defense.
• Birth of the Sankta race: The Farchaser dispatched a group of Teekaz warriors to return to the Silver Mountain Range to recover the secrets within to use against the Elders. When the warriors reach the range, starving and near-death, they encounter The Law in an inactive state and try to reactivate it. In desperation, a Teekaz breaks the decree of the Farchaser that forbade cannibalism. With this act, the Law recognized their desire to live and reactivates, bestowing halos and wings on all present. These Teekaz warriors became the first Sankta of Terra.
• Destruction of the First Kazdel : In an act of desperation in the last days of the war, the Farchaser summoned Amnannam, the first Originium, completely destroying the attacking Elder forces as they march on the last bastion of the Teekaz. However, the event cursed Terra with Oripathy, gave the Teekaz their susceptibility to Oripathy alongside their inherent link to Originium, and led to the imprisonment of the Myriad Souls within the Assimilated Universe.
  • The First Catastrophe: The summoning of the Amnannam led to the onset of Catastrophes, which continue to plague Terra into the present day.
  • The Age of Exile (8000~6000 BCE): A period marked by the constant diaspora of the Teekaz people following the numerous destructions of partially-rebuilt Kazdels. Thus, the Teekaz became the Sarkaz.
• Foundation of Sargon: The Aslan Conquest unifies the tribes of southwestern Terra, and lay the roots for the foundation of Sargon, the first non-Teekaz nation with an established sovereignty.
• Foundation of Yan: The first True Lung, Yan, unifies the people of the west under a single banner, giving birth to an empire named after himself. However, he dies prematurely, just when his country started to prosper.
  • The Hundred Clan Rebellion/Baishi-zhi-luan: A major civil war breaks out following the death of Yan the Chieftain, resulting in the empire's fragmentation and the collapse of the feudal system, until the rise of a new emperor quelled the conflict.
  • The Great Hunt: The great war waged by the True Lung who subjugated many Feranmuts in order to force them to serve the dynasty. Despite countless sacrifices, the war was nevertheless a success through the aid of numerous mortal heroes and a haughty, traitorous Feranmut named Sui who sought to be worshipped as a god. The result was the full subjugation of the Feranmuts, the execution/expulsion of the survivors, and the fragmentation of Sui into twelve siblings under the Emperor's order. See the page for more info.
• Foundation of Kjerag: The Feranmut Kjeragandr, seeking a safe haven from Terra's Catastrophes, led her people to settle in the freezing mountains—thus leading to the foundation of the small yet peaceful theocracy known as Kjerag, where she serves as the nation's Goddess and protector.
• Foundation of Victoria and Tara: The Draco tribes dwelling in central Terra warred amidst themselves, yearning for a power similar to that of the Sargonian Padishahs. As a result, the kingdom of Victoria was formed, led by Draco tribes who wanted to reform their political structure to mimic the Royal Court of Sargon. The conservative clans united and fled from Victoria, founding Tara to the south.
• Foundation of Laterano: The Sankta race united together under the guidance of the First Saints in order to resist Sarkaz harassment. The nation's foundation was marked by the construction of the Tower of Revelation, a belfry that wouldn't ring for generations to come.
• Foundation of Leithanien: Leithanien was formed from a confederation of ten tribes bound under the Güldenesgesatz.
• Legend of the She-Wolf: The foundation of Siracusa's mafia tradition by the Six Families of the She-Wolf, as well as the establishment of the city of Sette Colli.
• Foundation of Minos: A group of displaced refugees led by the poet Ceresia settle at the mountain range and establish Athenius, future capital of Minos. However, their peace is thwarted by foreign invasions until Ceresia, after receiving the call of the "Heroes" at Mount Hymnoi, drives them back with her Lyre of War. Ceresia is thus revrered as the first Heroine of Minos.
  • Expansion of Minos: With the foundation of Athenius, the Minoans decide to expand to the surounding lands and establish new cities and hero cults, giving rise to the city-states of Corinia and Lachedamon.
• Birth of the Hippogryphic Empire: After escaping from the Teekaz counterattack, the Hippogryph Liberi settled in the northern mountain ranges, eventually naming the land after themselves and building a prosperous, short-lived empire. They would subjugate the Ancient races, seeing them as lesser—with the Ursus making up the majority of those enslaved by the Hippogryphs.
• Foundation of Kazimierz: A long time ago, Kazimierz was simply known as a vast, fertile grassland that was disputed by many different factions. The Pegasi Royal House, refusing to be subjugated by others, formed the earliest knight orders and defeated their rivals and later established their hegemony over the region.

While they were successful in driving back the Poltergeist King, they destroyed the Stargate responsible for the incursion through means unknown, causing it to explode. The exact fate of the Khagan and Lugalszargus are uncertain, but it can be logically assumed that they were annihilated by the gravitational collapse resulting from the Stargate's destruction, sacrificing themselves to save the world from the Collapsal threat.
  • The Aslan Wars: The power vacuum left by Lugalszargus' death resulted in a civil war between the Aslan nobles.
• The Ursi's Uproar (0016-0027): Following the Nightzmoras' retreat from Deity Grypherburg in Year 16, the Hippogryphs issued a harsh reconstruction project using consripted Ursi as their main workforce.

50s

• The Eastern March (0058): In order to defeat remnants of the Hippogryph Empire, Igor the Great's son, Emperor Aleksey Igorevich "the Young" issued a national policy to purge the remaining Hippogryph, which later deteriorated to indiscriminate war and the beginning of Ursus expansionism.

The Royal priests would take Labhréathach's body to the Dark Woods to perform the fire-returning ceremony a week later.
• Reconstruction of Na Saoirsí: The reigning King Gaeil was forced to let Victoria rebuild the Taran capital of Na Saoirsí to their image. According to legend, the stonemasons responsible for building every structure in Na Saoirsí refused to add ornaments to the citadel.
• Arrival of the Liches in Leithanien: The ancient Sarkaz tribe of Liches arrive in ancient Leithanien and settle, teaching Originium Arts to the populace and assisting in the development of the region for the next five centuries, away from the Royal Court and politics of Kazdel.
• Higashi North-South War/Kokusen-shouran (0400-0807): The collapse of Higashi's Ritsuseikoku system gave rise to the militant bakufu led by the first Shougun Oniayame Shigekazu.
