Arknights Endfield Glossary of Important In-Game Terminology for New Players
New players stepping into Arknights Endfield are met with a dense wall of lore terminology — Originium, Oripathy, Reconveners, the AIC — all introduced at pace without a traditional glossary screen. This Arknights Endfield glossary compiles the most important in-game terms so you can follow the story confidently from your very first session.
Understanding Endfield’s Terminology System
Arknights Endfield launched globally on January 22, 2026, developed by Hypergryph as a spin-off of the 2019 tower defence game Arknights. Set on Talos-II — a moon colonized by pioneers from Terra — Endfield inherits much of its parent game’s vocabulary while adding significant new terms. Players familiar with the original Arknights will recognize Originium, Oripathy, and Operators immediately. New players should treat this glossary as essential background before diving into the main story, as dialogue assumes familiarity with many of these concepts.
Essential Arknights Endfield Glossary
| Term | Definition | Relevance in Endfield |
|---|---|---|
| Originium | High-energy mineral powering most technology on Talos-II | Core resource for combat, base building, and story |
| Oripathy | Incurable disease caused by Originium absorption; victim eventually crystallizes | Major story and character motivation driver |
| Originium Arts | Combat techniques using Originium energy | Powers operator skills and elemental abilities |
| Endministrator | The player character; leader of Endfield Industries | Your in-game role and the main protagonist |
| Reconveners | Operators who carry inherited memories of original Arknights characters | Explains why Endfield characters resemble Arknights operators |
| AIC | Automated Industry Complex; the base-building and production system | Core gameplay loop alongside combat |
| Aethergate | Dimensional portal through which Terra colonists reached Talos-II; now destroyed | Key backstory element explaining Talos-II’s isolation |
| Aggeloi | Mysterious hostile entities threatening Talos-II civilization | Primary antagonist faction in the main story |
| Blight / Corruption | Supernatural disaster distorting environments; spreads from the Aetherside | Environmental hazard and story threat in Wuling and beyond |
| OMV Dijiang | Endfield Industries’ airborne headquarters orbiting Talos-II | Your home base and main hub between missions |
As you progress, you’ll also encounter Protocol-Originium (refined form powering Dijiang’s core), Aetherside (a mysterious parallel dimension linked to the Blight), and Civilization Band (the inhabited, defended zone of Talos-II). These are introduced gradually, but this foundation makes each reveal land with more impact.
