In the twenty-fourth century, humanity controls nearly a hundred planets. The Terran Federation is a strong, centralized government with a powerful space navy used mostly to stop secessionist rebellions when force is needed. A hostile first contact with an enigmatic plant-like alien species, the Malidar, leads to a long and bloody war. Mankind's ingenuity, advanced technology and warlikeness clash with the Malidar's endless numbers, unknown biolology and imperscrutable intentions. Our story follows the tale of the heroes of the Federation on the Astral Navy Vessel Asimov in their efforts to win the war.
