In the past, our Earth was a normal place but is reaching its end because of extreme climate change. The planet is no longer a single united land, but it is divided into four very different regions, each one shaped by a different environmental disaster.

The first region is a vast desert. Temperatures are extremely high, water is almost impossible to find and strong sandstorms make survival very difficult. The second part of the world is almost completely covered by water . Continuous tsunamis and earthquakes have destroyed cities and lands, leaving behind a flooded territory full of ruins. The third region is a dense jungle. It is very humid, with constant rain and thick vegetation. Although it is full of life, it is also dangerous, as wild animals and diseases are common in this area. Finally, the last region is a frozen land. Temperatures are extremely low, everything is covered in ice, and surviving without protection is almost impossible.

In this destroyed world, only one person has the ability to survive in all these environments: Atenea. Thanks to her unique adaptations and extraordinary abilities, she is the only human capable of enduring such a hostile and broken planet.
