Constructing Ultimate Destruction

The radioactive spectrum was released in a solitary massively destructive
blastwave.
billions fall victim to the power of one soul being.
The black hand reaches across the globe a final time to extinguish the tiny
flicker of mankind.
You'll be buried up to your neck in sand, and have molten lead poured down your
throat.
A sky burial is at hand, let the cosmic avian gods flock to gorge on thy sacred
flesh of the earth.
