At the dawn of the 5th millennium, humanity has come to live in harmony with nature. His knowledge of the world and the weather has evolved. Pacts have been made between humans and animals. To raise awareness, agencies offer trips to major natural disasters of the past, on the sole condition that travelers do not interfere with the worlds they visit.

The resort of Chamrousse and its mountains are at the origin of the harmony found in the four corners of the globe.

But, for some time, this balance seems destabilized. Plant species are disappearing and the "Smog", this thick fog of pollution, reappears in cities and on the mountains.
You are part of the Unit responsible for protecting the weather. Missioned by Chamrousse and under the command of Téo, you immediately go into the past of the station.
