He had made his way far from the riverside, trailing an erratic route across the moraine and through the plains. They held little interest to him, being nearly barren of valuables; the thought had crossed his mind to double back of course, to return to that icy river and the company of the gray woman. She had been kind, which he had not expected nor received well. She was behind him now, as were the many things from which he fled, so Kasiya focused on what lay  before him. The light had begun to fade as he traipsed across the plains, and the world around him became less saturated - until the evening had unfurled, leaving the boy desolate.

Before he knew it, the solidity of the ground became questionable. Whatever rooted the plains in place had somehow vanished, relinquishing whatever hold it held across the substrate; his steps were slowed by the sudden wetness of everything, but he continued - figuring it was his imagination, or perhaps the nights here happened to be chilly and damp, unlike what remained of his dry home. With one errant step, Kasiya plunged beyond a simple few inches, and was suddenly neck-deep in some kind of muck. The mire swallowed him around the same time as he heard a snapping - like a tree being pulled out roots and all - but he was distracted, and merely whined to the wind for help.
