Long ago there were theories, predictions and debates about the world ending after the 20th century and they said, it will happen in the year 2000 but nothing ever happened. No meteors or big tsunamis and giant snakes ever came and the world continued normally till the year 2025.

Suddenly so many people started acting differently, some lost their minds and acted like zombies and died vomiting blood. The scientists across the globe tried to find the reason but they couldn't find anything. It was like a disease spreading across the globe and millions of people started to commit suicide and many people began to kill their family and then they lost their minds and died coughing blood.

As time passed, MC was born into a world where only 10% of humanity was left in the year 2032.

Over time billions of people died, some committed suicide and many died from a mysterious virus. The Earth's climate started to change many times which caused tsunamis and volcanic eruptions which led to billions of deaths.

Cities had gone underwater, even at that time war was still happening. But not for money - for food and shelter. MC grew up in that broken world.

People began to kill eachother for food and water and the level of oxygen were decreasing, everyone started to wear oxygen mask

Sea level started to decrease, almost 88% of trees went extinct, many deep sea fishes died , many species went extinct by the year mc born. Many cities became ruins and abandoned forever.

The colour of the sky turned brown forever, humanity never saw a clear blue sky since 2025, not even blue and the sun temperature started to increase and decrease everyday.
