Colonist. Being human

Somewhere in space there is a celestial body that flies wherever it wants. A body that brought together all the heroes of this story. Perhaps this is where the story about the Colonist should begin... But allow me a small introduction. If we imagine some distant (or not so) future, people are unlikely to stay on Earth. Most likely, they will fly to explore space. The thing is that people may not be the only race in the Universe. Other races will call people conquerors from a blue star, conquistadors on iron ships and consider them scoundrels. But what if people simply have not yet let go of their mother Earth and are afraid to meet their father Space?
