He paused, almost missing a step when she mentioned the meaning of his name.
"Yes, that is what it means," he said quietly, mostly to himself. Nobody had asked or brought up the meaning of his name in many, many years. Certainly not since his faith was broken.
He gave her a patient look when she said he'd not believe her, and listened.

His Father's wildest creations, left free. Beauty was from the time just before human influence started to truly shape more land than it left alone.
