Chernobog (Чернобог), formally known as Federal Territory of Chernobog (Федеральная территория Чернобог) is a nomadic city of Ursus.


Chernobog was once an old Ursine nomadic city that was almost torn down. However, in Terran Year 1070, twenty years before the events of the Main Theme, the Boris Group, a small mining company, unearthed a mysterious ancient device named the "Sarcophagus." Upon hearing the news, Count Boris, an Ursine noble and the leader of the mining company, decided to use the Sarcophagus to rebuild Chernobog into an industrial city. His aim was to win over the struggle against the Ursus Imperial Army, which controlled much of the Originium mining in the country. As Chernobog expanded rapidly, many smaller cities began to join Boris' venture not only because of his generosity, but also as a plan to defeat the military. Many scientists were sent to Chernobog to investigate and provide maintenance for the Sarcophagus.[1]

However, the scientist group led by Kal'tsit made a breaking discovery. They discovered that not only the Sarcophagus is indeed very ancient, but also they realized that the device could bring both a potential revolution and chaos to Ursus. Feeling that their interests were threatened, the Ursus Fourth Army, led by Grand Duke Vanya, sent several secret police to investigate the Chernobog scientists. The secret police used brute forces to force Sergei, one of Kal'tsit's students, to reveal the secret. In order to stop their future plans, the Fourth Army massacred the scientists. Ironically, the Count provided shelter for Sergei from the massacre due to his massive contribution to the city.[2]

After the massacre, the Ursus government proclaimed that it was an accident. The parents and friends of those victims were given warning by the secret police to shut up. Meanwhile, Sergei led the surviving scientists to form a new research team four year later (Terran Year 1080).[3] Meanwhile, Boris appointed himself as mayor of Chernobog in order to prevent any external interference to affect the city's development.[4] But with their morale strained by the tragedy, both Sergei and Boris could not get new result from the device. The Sarcophagus was eventually sealed off and left forgotten. Meanwhile, the Count, who was benefited by the Sarcophagus' research, had become unharmed by the military and continued the industrialization of Chernobog, making it an important city to Ursus. At some point however, Boris came into conflict with Grand Duke Vaikal and the Third Army over the price of raw materials for manufacturing. However, none of the clandestine attacks ordered by Vaikal managed to shake the city off. Moreover, Boris managed to arrange terms with the military, forbidding them to station within the city. By that point, Chernobog was neither bonded to rules of the military, nor by the nobility.[2]

As the city of Chernobog industrialized, more and more cities emerged and rose in prominence all around Ursus, trying to replicate Chernobog's success. At the same time, many Infected became unsatisfied with the local government. Consequently, the newly-formed Reunion Movement took the opportunity to start a violent riot in December of Terran Year 1096. On the other hand, the crisis was actually manipulated by the "immortal" Kashchey and his supporters, Grand Duke Baikal, Viscount Kerque, and the Ursus Third Army, as part of revitalizing Ursus' imperialism. The city was once manipulated by Talulah by having its core city set on a collision course onto the Yan city of Lungmen in an attempt to start a war between the two empires, though it was eventually foiled by Rhodes Island.

In the aftermath of the crisis, Chernobog was basically abandoned by the Ursine government, and even though the surviving plates are being integrated into other cities and the refugees can only remain in the designated asylum shelters in the meantime, there has been attempts to rebuild the city.[5] Currently, new plates are being built over the ruins of the old city.[6]

  • Count Boris
  • Count Andrey Rostov: Rosa's father and patriarch of House Rostov, a noble family that rose in prominence following the Great Rebellion. He held a considerable reputation in Chernobog's upper class and was friends with Count Boris. Howeve, the destruction of Rostov Industries's HQ and the loss of his largest customer during the Chernobog-Lungmen Crisis would cause him to momentarily fall from grace.[7][8] He and his wife managed to escape and flee to another city, but assumed Rosa didn't survive during the uprising.[9]
  • Sofia: A former maid of the Rostov family, who had to quit her job at some point before Reunion's uprising and move to Victoria to treat the illness of her son, Alexei. She's currently receiving treatment for her Oripathy in Rhodes Island.[9]

Sarcophagus researchers

  • Sergei: Misha's and Alex's father, as well as one of Kal'tsit's collegues and students. Due to his collaboration with the military, he was considered a "traitor" for selling off his collegues in order to save himself.[2][3] However, he would later be tracked down and killed by Lyudmilla, with the aid of Alex, as a vendetta for his actions[10]
  • Astrov: Lillia's husband. He was the first who got shot by the Fourth Army.[3]
  • Ilia: Lyudmila's father.[3] Following his death, Kal'tsit would send the young Lyudmilla to Siracusa for her safety.[11]
  • Romanovich: One of the researchers briefly mentioned by Lillia. Although his death was officially declared as an "accident" by the authorities , his brothers never believed that. The news about his death would force his family to sell their whole estate and leave the city.[3]
  • Vampilov: One of the researchers briefly mentioned by Lillia. Following his death, his father went mad to the point of even fantasizing about still going hunting fowlbeasts with his son by the river.[3]




Chernobog is a Slavic deity of bad fate whose name literally means "black god." Interestingly, the name is similar to that of Chernobyl, where the 1986 Chernobyl Nuclear Power Plant disaster took place.


  • The Chernobog Sarcophagus may be a reference to the CNPP Shelter Structure, commonly known as the "sarcophagus."
  • Prior to Arknights' beta version, Chernobog seemed to be intended to be named as "Chernobyl," at least according to the cryptic message from Koshea in Arknights' official doujinshi CRAVE which was published back in 2018.
