Whitefish River Here comes the sun

he had followed the river for most of the day, after descending the Sunspire and with no will to go home just yet. watching the river waters push past him in a silvery rush of motion, his gaze would occasionally follow fish, or the odd sparkle in the current. When he next glanced up, the sun had almost begun to dip below the horizon. Knowing that this meant that he ought to be home very, very soon, the boy paused, glancing back the way he had come. He had wished to go farther, but that would have to wait until another day.

but he had yet to move when suddenly a gleam in the rushing water caught his eye, and, quite impulsively, he dipped his muzzle into the creek, careening water not deterring him as he gripped a stone with his jaws delicately and wrenched his muzzle out, dropping his prize a safe distance way by his paws. A pebble, but some sort of glistening purple crystal was mostly visible, rounded and smoothed by the river. Very interested in this, he peered at it intently, nudging it so that he may see the entire thing.
