He lay listening to the water drip in the woods. Bedrock, this. The cold and the silence. The ashes of the late world carried on the bleak and temporal winds to and fro in the void. Carried forth and scattered and carried forth again. Everything uncoupled from its shoring. Unsupported in the ashen air. Sustained by a breath. Trembling and brief. If only my heart were stone.
