The world of Arknights is alternative to our own with several major key differences.

General Overview

The world of Arknights is constantly plagued by natural catastrophes called Disasters. Its cause and origins are unknown, but it has caused most civilizations to adopt a mobile, nomadic lifestyle. In the wake of Disasters, a substance called originium is left behind. While it is infectious (causing a disease known as oripathy), originium can also be utilized for energy, to perform magic, and other things. As such, originium industry thrives, leading to the birth of mobile cities, which makes up the majority of the world.

The dominant race is also made of populations of semi-animalistic humanoids called Ancients. Ancients are more susceptible to oripathy than normal humans are, making them generally fearful of those infected with oripathy.


The following are the key differences between Arknights' world to our own.


Originium is a fictional substance in the world of Arknights. It is left behind after a Disaster in great quantities and is highly infectious. Originium can serve as an energy source or for building materials, and its infection is generally associated with magical techniques known as Originium Arts or simply Arts. Originium powers mobile cities, and the artificial creation of armaments based on Arts allowed non-infected to use a semblance of the Arts too, changing the face of warfare.


The disease caused by originium infection is called oripathy, and it has 100% lethality rate. Those infected with oripathy will slowly show signs of originium growing on the surface of their bodies. After an infected dies, the originium that grows on the surface of their bodies will be dangerous to those around them, as they may potentially infect others. This has lead to general discrimination against the infected, a worldwide societal problem that both Rhodes Island Pharmaceutical and the Reunion Movement aim to fix with their own respective ideological takes on the problem.


Humanoids with animal-like traits that make up the majority of the population in the world of Arknights. The Ancients are at higher risk of being infected with oripathy. The classification of Ancient races are based on the animals they resemble or the traits that physically show, as will be listed below.


There are many factions in the world of Arknights, each with their own interests and working towards their own goals. These factions may be international companies, nations, or the races themselves.
