A Graver Menace

A graver menace than you think exists,
Between the tropics and the midnight sun,
Above the moon, behind a loaded gun,
In facets of Brazilian amethysts,
With lovers, thrilling at their endless trysts,
On sneakers with the laces come undone
So you fall down when you attempt to run,
Among the knights who figure on the lists.

Somewhere on earth, somewhere in time and space,
One threat is made, a heaven's grace is lost,
A woollen blanket, left where it was tossed,
Begins to weather, and the human race
Begins to lose its grip. Cut to the chase:
Forget the poetry now. Count the cost.
