Ibn Khaldun

The streams thinned and the gentle give of the loamy earth beneath their feet began to shift easier & easier. Great mesas of rock towered overhead, the tables from which launched great birds of prey and whose coloration layered reds & oranges atop greys & browns. Dunes began to snake between feet where grass once stood. Save for the buttes & mesas, the remainder of the land stretched vast and unfenced neither by timber nor mountain.
