Those of keener eyes who frequent the docks could perhaps spot a dim, orange glow along the Southern shores of the beach, near a single tree cresting the coast.
A paper lantern, held closely by a cloaked figure of average height.
Perhaps that's all to the sight that such a sparse audience could find interesting, aside from the gentle lull of the waves, and a breeze that rustled their form of fabric.
After about ten minutes, its glow paused near their hood. Observation, perhaps. Or whispers, given the time of year.
Then, after ten more minutes, it's lifted into the sky.
Up, and up, and up...
...until it intermingles somewhere with the stars.
There's no such light to supply any onlookers with the figure's remaining location - for they had come and gone much like the waves themselves.
