Clouds of iradiated dust flowed across the shattered earth, broken apart and reformed by the edies of solar radiation. The last cry of a ruined empire, ground to dust by it's own self destructive ways; left to be artifaced by the wind. The Sky was the color of nothing, a blank black webbed with cracks of grey; akin to a fractured liquid crystal display.
No sane man dwelled in the wastes.
The garden of neon is where they went.
