Post-Apocalyptic Wastelands

The profound impact
Put the inhabitants in a gasp!
In which ascendancy
That made their planet descent

The earth will transfigure
Into a plantation strict
Of an eloquent exigency
With grit and persiflagness!

Air travellers and their planes subsided to the grounds
And there was not a single light on the surface of the earth
Power was generated, but not used at all
A comprehensive told of an immense, electromagnetic
Pulse in a scale larger than the surface of the earth itself

This bomb had no purpose of killing!
