The Planet Scavengers

It was the distant future of Earth, and the mother planet of a glaxy-wide empire had been forgotten by her far-flung colonies. Forgotten, tired, old and stripped of her ores and natural fuels, Earth and the scattered bands of humans left behind were totally unprepared for the invasion of the strange, monstrous Kar-chee from the depths of the stars.

The Kar-chee had come to strip Earth of the few natural resources the planet had left–to crack the marrow of the aged planet and scavenge whatever of worth was left there. It was a massive, planet-wide operation in which continents were sunk and oceans drained, and if the tiny, insignificant humans died in these holocausts, what did that matter to the Kar-chee?

It mattered to the humans…and, at last, they began to fight.
