Once upon a time, the NASA tried to travel to Mars. They had everything prepared to reach mars and survive there for months.

Everything was fine until the spacecraft get trapped in a wormhole and travelled billions of kilometers light away from the Earth and from Mars.

When they get out from the wormhole, the spacecraft was too damaged to continue the travel so it crashed in the nearest planet.

When the spacecraft crashed in that strange planet, they discovered that the gravity, and the gases were the same that in the Earth.

They find out live in that planet that they called Niam. They tried to communicate with them but the didn't speak the same language.

The Sracsó (Called so by humans) were peaceful habitants and they brought humans to their village to show them the history of the planet.
