The past decays

Nightingale, black,shimmering,fly,
Into the pristine crystal sky,
Sing a song for the lost tonight,
Of castles,dragons and heroic fights,
Of a quest for newfound glory,
Of the start of the never-ending story,
Bubbling streams and rivers ply,
In the ocean they share their plight,
Unique in the moment of their source,
Overwhelmed by their uniting force,
Forgotten lay their weeping banks,
Of a love lost amidst their sands,
The past a caress of liquid hands,
Motion alone of the tireless band,
Hearken the groan of the heart,
Beats to fulfill a golden start,
In each moment of its strife,
Knowing that each beat ends its life,
Yet hammers on like soldiers of old,
Marching through the tireless cold,
And in its moment of divine test,
It dies, but it deserves its rest...
