Human: Generate a brief description of a mystical scene outside a wilderness glade with a rock, white mass, reptile, and skin. Assistant: 
The ground is broken by a large, flat rock. The face of the stone is weathered, but one side is marked with straight, regular scratches, and has been worn smooth by constant rubbing. On the ground below the rock is a strange white mass that looks suspiciously like the skin of a reptile.
