Mylea is a planet about the same size as our Earth. The composition of the planet was also very much like ours, including great oceans. But the land mass was different. Mylea had a contiguous ring of land around the middle of the planet.
As the Myleans evolved into a civilization, because there were no great ocean barriers separating continents, as on our Earth, their people were essentially one race and one culture from the very early years.
The Myleans developed into a race very much like humans. A Mylean walking down a city street, if dressed in our clothing, would not likely be noticed as being alien. However, their culture and their personalities were very different from ours.
Mylea, due to its mono-ethnic and homogenous culture never experienced the constant state of war that has been the hallmark of Earth. War was a completely alien concept to them. They were a disciplined and pragmatic people who developed technologically at a very fast pace.
Mylean Technology was far advanced compared to that of our Earth. They had mastered Gravity waves and used gravity propulsion systems for travel, both on their planet and into space. Their physics could create electricity at the atomic level. They could disassemble matter and reassemble it into another form.
Their bio-chemists had long ago solved the mysteries of DNA. Their medical doctors could manipulate DNA to correct possible birth defects and advance the age at which their people might live to many multiples of that of Earth. It seemed that they could accomplish anything technologically.
Then they were suddenly faced with the ultimate challenge. Their planet was in mortal danger from an approaching black hole. Their scientists could not divert the massive gravitational field of the black hole and it seemed their planet was doomed.
However, their most celebrated scientist proposed a plan to save Mylea. It was an audacious plan whose size and complexity seemed impossible to conceive, much less implement. But he convinced the Myleans that it was their only chance to survive.
Their epic effort encountered an unforeseen problem. Their technology could do miraculous things, but the only solution to their enigmatic problem lay in the hands of a single Earthling. Finding him and getting his cooperation was essential, whatever the costs.
