Arknights: Endfield Lore Explained — From Terra to the Corporate Frontier of Talos-II

Arknights: Endfield isn’t just a 3D action RPG with factory systems — it’s also a deep sci-fi narrative rooted in the Arknights universe. As the Endministrator of Endfield Industries, you’ll explore a world shaped by history, conflict, and the enduring echoes of Terra. This guide breaks down the lore of Talos-II, key historical events, major factions, and how Endfield connects to the original Arknights world.


A World Untamed — Talos-II’s Core Premise

Arknights: Endfield transports players to Talos-II, a moon colonized by pioneers from Terra — the original setting of Arknights — 152 years before the game’s story begins. These pioneers crossed an interdimensional portal called an Æthergate, which was subsequently destroyed roughly a century later, cutting Talos-II off from its home world.

Without that link, the colonists were forced to build a new society in a hostile frontier. Talos-II is filled with:

  • Vast wildlands and untamed frontier terrain

  • Supernatural threats like Corruption (a mysterious force that warps environments)

  • Natural hazards and dangerous beasts such as the Aggeloi.


Historical Timeline — From Æthergate to Isolation

Arknights: Endfield Lore Explained

Understanding the backdrop helps you appreciate why the world of Endfield feels so different from Terra.

Era / EventWhat HappenedNarrative Impact
Colonization (~152 years ago)Terrans from Terra used the Æthergate to reach Talos-IISets up human settlement on a new world.
First Aggeloi War (~100+ years ago)Destroyed the Æthergate, isolating colonistsForces self-sufficiency and frontier society.
Rise of CorporationsTraditional nation-states replaced by powerful corporations, unions, and syndicatesCreates the game’s political landscape.
Spread of CorruptionCatastrophes and environmental distortions emergeShapes hostile exploration zones.

This timeline explains why Talos-II is both familiar and alien — it shares ties with the original world but has diverged drastically.


Factions of Talos-II — The Power Centers of the Corporate Frontier

Unlike Terra, where nation-states and paramilitary groups dominated, Talos-II’s politics are driven by corporations, unions, and syndicates.

Endfield Industries

Your own faction — a major industrial force focused on frontier construction and technological innovation. Originally established in partnership with Rhodes Island, Endfield Industries now leads efforts to:

  • Defend settlements

  • Counter environmental hazards

  • Pioneer new technologies like the Automated Industry Complex (AIC) and Protocol-Originium systems.

Endfield Industries’ authority comes from its critical role in rebuilding civilization after isolation.

Other Key Factions

According to community-curated sources, Talos-II includes multiple organized groups:

FactionRole / Influence
United Workers’ Syndicates of Talos-II (UWST)Industrial union focused on heavy production and resource logistics.
Hongshan Academy of SciencesAdvanced research institution with regional sway.
Talos-II General Chamber of CommerceMajor economic power managing supply chains.
Order of Steel OathMilitant order with unique ideology.
Cabal of TranquilitySmaller ideological/spiritual collective.
Rhodes IslandFrom Arknights, involved in Endfield’s history and operations.

This faction complexity creates a rich political tapestry that influences missions, alliances, and narrative progression.


The Reconveners — Echoes of Terra’s Past

One of Endfield’s most intriguing lore devices is the concept of Reconveners — special individuals tied to the original Arknights operators.

Reconveners are not simply clones. Instead, they are reconstructed beings originating from fragments of a First Originium crystal that was brought through the Æthergate. That crystal carried vast amounts of information and memory data about operators from Terra. During the First Aggeloi War, that data became corrupted and trapped in a strange realm described as the “Assimilated Universe.”

When select fragments of this data are decrypted and brought into realspace, they manifest as new individuals — Reconveners — who resemble former Arknights operators in looks and ability, but with distinct personalities and identities.

This narrative device elegantly connects the stories of Terra and Talos-II while allowing Endfield to build its own characters and drama.


Your Role — The Endministrator of Endfield Industries

As the Endministrator, your mission is far more than exploration: it’s about rebuilding human civilization in a hostile world. The playable narrative begins in places like Valley IV, barren but rich in resources essential to the survival and growth of outlying settlements (as confirmed by lore previews and wiki entries describing expansion and resource conflicts).

Beyond combat, base-building and strategic infrastructure — such as the AIC system — are intimately tied to the story. You aren’t just fighting monsters: you’re solving the problems of a civilization cut off from its past.


Thematic Links to Arknights (Terra)

While Endfield stands on its own, its thematic DNA is unmistakably linked to the original Arknights:

ThemeArknightsEndfield
Survival in hostile environmentsCatastrophes force survivalCatastrophes + Corruption reshape Talos-II.
Originium’s influenceCentral to conflict and abilitiesStill pivotal; causes distortion and powers operators.
Organizations vs threatsRhodes Island vs ReunionCorporate and syndicate power plays on Talos-II.

Rather than merely extending the original story, Endfield interprets these themes in a frontier context: here, humanity is not just surviving — it’s expanding, exploiting, corporate-driven, and reshaping a world once forgotten.
