Silent Invader

Behold, ghostly streets of a ghastly time.
All is still, but not becalmed. As though
the dread end-of-times has arrived but
it has not entirely. Only those whose time
has come prematurely by nature's decree
primarily those who have lived long for
there are no life-time guarantees or rewards
for existence and a strange new threat has
made that evident as it thrives finding new
victims everywhere it inveigles its raw and
evil presence. A grey miasma of dread 
and fear hovers everywhere, fixing peoples'
minds on what might be the inevitable as
their spirits shrivel in dismay and life's
spark assumes an elusive edge. In stark
panic a struggle begins as populations strike
out to acquire life's necessities looting
what they feel will sustain them, depriving
others of sustenance as humankind reverts
to survival imperative and leaders haplessly
enact laws in wan hope of overcoming this
barbarically destructive weapon mankind
itself unleashed while dispassionate nature
engrosses itself unravelling the outcome.
