Interior text

Today this star, tomorrow the universe!

After four centuries of space travel, man had explored and colonized every inhabitable world within a radius of four hundred light-years. Not a trace of any other intelligent life had ever been sighted. It seemed as if the universe belonged solely to mankind.

Thus the sudden discovery of another, more advanced race already busy colonizing far-off planets shook the very foundations of human feelings of superiority.

But deflated egos weren't the only problem. Man was determined to continue spreading outwards, and the aliens obstinately had the same plans. What could prevent the inevitable clash of the two stellar empires and the oncoming of destruction to all their worlds?
