World History

Old World
20 years ago before New Calendar, the Old World was destroyed.

It’s said that the Old World was destroyed because of a series of forbidden and unethical experiments. On the Ashlands, there are many rumors spreading among humans: Some of the Old World’s actions angered the Kalendaria, so they were destroyed by ‘Them.’ The survivors passed the test, so they were saved by ‘Them.’ While Life Ritual believes the destruction of the Old World only an inevitable result of normal development.

Nine future-facing research institutes were established. The Third Research institute in the south specialized in artificial intelligence and developed the Source Brain and eventually became Mechanical Paradise. Back then, humans forcefully built a magnificent new city for this research institute. Another research institute researched human consciousness uploading and created the Eternals, eventually becoming the Monks Conclave. The Eighth Research Institute researched Awakening and became an organization that suppressed investigation of the Old World's Destruction.

According to the Source Brain, the Old World's technology had reached astonishing levels. A technology like controllable nuclear fusion that could change the entire planet’s fate had a critical breakthrough. Although it didn’t succeed in the end, they had already seen the dawn of hope. Similarly, automation and intelligence were widely used in various key areas. After the Heartless disease broke out in certain military bases, people who had lost their minds might’ve chanced upon something or pressed something according to their instincts. The first wave of strikes happened just like that. Without anyone presiding over them, the various countries’ smart systems counterattacked according to the preset conditions and reactions. Since nobody stopped them, it soon became a vicious cycle. The war developed to the point where they threw all kinds of high-energy weapons at each other. The world was then destroyed in a short period of time. Before the Heartless outbreak, the Old World showed no signs of destruction.

Certain factions had already built shelters before the Old World was destroyed. For example, Pangu Biology's underground building.

Chaotic Era
When the Old World was destroyed, in a short period of time, a large number of humans in each city became Heartless, and many more people died at the Heartless’ hands. Therefore, after humanity’s law and order collapsed, ushering in a great famine, they quickly lost a large portion of their city’s ‘food reserves.’ Less than 1% of the original population remained.

New Calendar
After the destruction of the Old World, after a long period of chaos and disputes, humans finally managed to rebuild order in certain areas and started the New Calendar.
