The Ziggurat

The Constructus Corporation saw the destruction of the power points well in advance
The Ziggurat already had left the Earths surface
And was far out of harms way by the time the chaos began

This goliath definition of comfortable living
Was fortified by an entirely impenetrable ancient defense system
And soared several thousand feet above the hell-realm below, following the sun

The Ziggurat housed an entirely autonomous society
Who lived completely harmonious lives and were virtually free from suffering
The airborne megalopolis existed perfectly outside the laws of nature
