An alien landscape

The rattle and tumble of stones is continuous as they answer the call of the pink moon that hangs low in the sky. Her width stretches to almost half of the visible horizon. Tidal waves sweep the surface of this planet, crashing chaotically in the grip of the moon’s pull. The constantly shifting, rolling, waving surface glows dimly in shades of magenta, mauve and violet.

Purple pebbles ring
In constant tumbling answer
To pull of pink moon.
