The galaxy burns. The enemy, a race of alien scorpions, storms from star to star. Planets smolder in their wake. Across the galaxy, they hunt humans. Long ago, we humans had a planet of our own. Long ago, we could have resisted the scorpions. But today we are refugees. We are lost in darkness. We haven't seen Earth in two thousand years. We, the last humans, must band together. We must resist. We must fight the scorpions. And we must find Earth! Only Earth can unite us. Only Earth can kindle our hope. Only on Earth can we defend our species. Our homeworld calls us from beyond myth and shadow. We must find a way home. Or the scorpions will kill us all. Earth is but a memory. But we will not forget. Earth will rise again!
