Gunslinging...

They say things weren’t always this way. Fifty, maybe sixty years back, the unbelievable happened. A rock from space struck the moon, a great, big rock. The glassy white eye that watched over us went a’spinning off its regular rotation. This made all sorts of trouble. The seas went wild. Water rose and covered the land. The air filled with dust and water born bacteria. By the time the moon spun back to where it was supposed to be the damage was immeasurable. As the waters slowly receded the heat of the sun baked the earth dry where it had been. A series of solar flares smacked the earth like savage fiery hammers. They would have been rebuffed at least partially by the atmosphere, but it had been ruined in part by the mispinning of the moon. Civilization was destroyed in the process. New peoples rose up, claiming land as their own. They claimed to have been there all along, under the noses of the human race.
