My shadow cast against the grains

As sunlight fades across the blue.

A wetter shade than what remained

Untouched and radiantly new.

The coastal creatures teeming on,

I dove a little deeper more

Until the warmth relied upon

Became a chill I can’t ignore.

My sight accustomed as I sank,

My breathing muzzled by a thread,

My life reliant on a tank

Receding past horizon’s edge.

That distant home at shores afar

Was where I learned to walk and run,

But now I float within the dark

Until the day my mission’s done.
