Existence whispered, "Does an hourglass measure time or merely the presence of sand?"
To which the void replied, "It measures only the promise of emptiness—ever shifting and unbound."
As the grains tumble, one by one, Light muse in its descent, "Am I to fall or rise with each piece of time unspun?"
Darkness grinned, ever so faintly, "Rising and falling is just a rotation of the wind."
