Arknights Wiki

Rim Billiton is a country in the world of Arknights. It is an expansive mining company that actively exploits various Originium deposits around Terra and controls the territory south of Kazdel, which is administrated by a mega-corporation of the same name.

Rim Billiton's Originium mining activities cause much of their populace, the Cautus race, to suffer from Oripathy. While the company does not overtly persecute the Infected in the same manner as Ursus or Victoria, Rim Billiton sees their citizens merely as disposable workforce. The Infected are still discriminated upon to some extent, regarded as outcasts and facing difficulties in finding work and medical care.[1]


At some point, Rim Billiton went into conflict against Victoria during what was eventually termed the "Cage Incident." The cunning Victorian merchants manipulated and colonized the inhabitants of nomadic cities in two counties, leading them to mine more Originium ore and selling it to their own country. Infuriated over their exploitation, the local miners rebelled against the foreigners by tearing down the fences that encircled them. The aftermath resulted in the foundation of the Eureka Autonomous Prefecture — a Victorian-controlled enclave — and the merchants conceding their power over the cities back to Rim Billiton. Even so, the foreign companies still continually attempt to cheat following the treaty and the Billitoners' national laws.[2][3]

More recently, the nation has been experiencing a craze about planting carrots among its citizens. Such a trend is fueled by corporations and "experts" exaggerating carrots' nutritional values. If the situation remains uncontrolled, a steep inflation of carrot prices is all but certain, and the farmers would be unable to plant other crops as substitutes, likely leading to another crisis such as the "Cage Incident."[3]

In Terran year 1084, Rim Billiton worked together with Babel, under Theresa's leadership to excavate the Rhodes Island landship, a Rim Billiton mining barge repurposed as Babel, and then, following from the fall of Babel, Rhodes Island Pharmaceuticals' headquarters. As part of its contract with Babel, the Billitoners also provided security protection and cargo escort to Kazdel for two years.[4][5]

Notable people




  • Eureka Autonomous Prefecture: Run by Victorian mining companies, it was founded in the aftermath of the Cage Incident in response to the demands made by foreign merchants. However, with the increasing dissatisfaction among the locals due to harsh treatment, there are high chances that Eureka will soon return under Rim Billiton's rule.[2][3]


  • Steel Robot: A city in Rim Billiton where April and Savage came from. It is known for being the annual top producer of ores among all cities.[1] A mining accident occurred a few years ago, which later prompted Savage to join Rhodes Island.[5]
