It tells about a time when humanity, in general, has made great progress according to the Kardashev scale and left their world behind, too much power and advanced humanity is affected by such development, attacking each other without stopping and solving the unknowns in their new area.
This series really needs to continue. The balance of power doesn't affect the storyline, and there's no ridiculous power imbalance. Also, the philosophy is very good.
The story started too fast, I didn't like the fact that it started directly with the war before the characters were fully introduced, and it was explained in great detail, other than that it was very good.
