Welcome to Hera
Many years ago, in 2020, NASA has discovered that Gliese 581c was, in fact, not suitable for human life. But, just one solar system away, another planet was found. Gliese 582a, or "Hera".
The next space race began. America struggled to keep up with Russia, but in the end, Russia won. They were the first to create a ship that could travel at light speed. America joined them on the journey to the new land.
When they landed, they found a perfect world. Mild deserts, dense forests and grasslands, and two polar ice caps. Now, it was up to Russia and the US to create colonies/countries on this new planet.
