SHOWDOWN!

Unknowingly a man steps towards his death
As he watches predatory shades of amber
Catch light; in a biochemical orb.
Intentionally Mixing compounds, to kill, or paralyze.

Injecting barbs through history,
And admired in the sky
Suddenly the victim realized-
he was prey, and stopped- half mesmerized.

Years of molting
Have brought them to this place.
“Just please, don’t act in haste”
The helpless victim begged- but to no avail.

The desert winds howled,
And the victim cowered to the ground.
The deathstalker has won,
Leaving behind just one; of twelve signs.

WHO OR WHAT WAS THE KILLER?
