After the interstellar colonization era began, the first terrifying thing was that human beings were alone in the universe. Fortunately, this did not happen.
The second scariest thing is to discover that those alien civilizations are younger than humans.
The second most horrific thing did happen.
The colonists regarded this as mankind's luck and expanded unscrupulously.
But even luck can run out.
If you like the complicated historical stories between different interstellar civilizations rather than fast-paced and obscure hard science fiction terms, then maybe you can try it and experience the slow-paced interstellar epic in the world view of this book.
