Vault Colony

Vault Colonies are cities that are constructed underground, typically in order to protect citizens from nuclear radiation after The Nuclear Disaster of Great Werchasko and not habitable to live. The first Vault Colonies were established in the 1300s, and a new organization government known as the Vault Administration was introduced to manage these colonies. Currently, there are 14 colonies across the Jhino region, and to reach other colonies, people must use an underground railway which can take hours or even days.

## Catastrophic Event

The Vault Administration is known for having a powerful military to protect the colonies, and by 1371, the population of Vault Colonies had reached 200 million people. However, by 1395, several colonies began to experience uprisings, and the Zeyonic Empire emerged as the strongest after taking control of Vault Utopicha.

Unfortunately, the Zeyonic Empire caused the wipe out of 12.5 million people in Utopicha when they nuked the colony. The leader of the Zeyonic Empire, Webstar Zeyona, holds a new record for wiping out a population in just one week. This catastrophic event had a significant impact on the people living inside Vault Colonies, making their living conditions even more uncomfortable and difficult.

During the ongoing war between the Vault Colonies, the Zeyonic Empire has caused significant damage, having already killed 27.6 million people. In response, the Vault Administration forces have taken action against Zeyonic, including blocking several railways to prevent them from travelling to other colonies. Despite the war still continuing, the Administration has managed to outmatch Zeyonic in terms of military equipment. By 1310, Zeyonic Empire was ultimately defeated and forced to surrender. The Zeyona family, who were the leaders of the empire, were executed as a result. It is clear that the Vault Administration took a strong stance against Zeyonic's actions, and was willing to take drastic measures to ensure the safety and well-being of its citizens. Years later, the vault was named to Zeyona Vault under the government of Vault Administration.

Despite the defeat of the Zeyonic Empire, some colonies continued to rebel against the Vault Administration. In some cases, these rebellions were successful, with the rebels taking control of the colony and attempting to impose their own rule. However, these rebellions ultimately failed due to the Vault Administration's advanced military technology and weaponry. The Administration had learned from its experiences during the war with Zeyonic and had developed powerful new technologies to defend against future threats. This included advanced surveillance systems, cutting-edge weapons, and highly trained soldiers who were able to quickly respond to any threats to the colonies. As a result, the rebels were unable to make any significant progress in their efforts to take over the colonies. Instead, they were quickly defeated by the Administration forces, who were able to use their superior technology and tactics to regain control of the colonies.
