3,700 years have passed since a mysterious flash turned all of humanity into stone. Nature reclaimed the cities, skyscrapers collapsed, and the world returned to the wild.

Today, your eyes open for the first time in millennia.

It doesn't matter who you were before the petrification. In this new era, only your wit, your decisions, and your will to keep moving forward matter.

Explore forests, ruins, and villages. Gather resources, craft tools, discover the secrets of science, and meet characters fighting to build the future... or impose their own vision of the world.

Will you join the Kingdom of Science? Will you follow your own path? Or will you change the fate of humanity forever?

The new world awaits you.
