After the battle with the Aparoids, something started to go very wrong in Lylat... And without the Team to solve it, the darkness started to grow and swallow planet by planet. Andross wasn't death after all. Bearing a grudge against a single planet, he planed his revenge.
Now, the system is under his dominion, Corneria turned into his personal laboratory and plague after plague punished the population; only the stronger and the smarter managed to survive. However this wouldn't last for long... With the planet turned into a desert, the life almost gone, and the natural resources so scarce, Andross decided to finish it.
Here is where you come in; these are the last days of Corneria. Where will you be? Which will be your side? Will you stay until the last second? Or will you leave whenever you find the chance? Whatever you plan to do... the time for doing it is running out...
