Clinging to the rags I had left, I gazed out upon the full breadth of the Furnace and shook at what I saw.The world had been wiped clean of all trace of humanity. Sharp sandstone peaks protruded into the gray sky like a humped backbone, spilling into vast seas of sand on either side. Boulders and driftwood, the castaways of some bygone mountain, cast the only disruption upon the land. And I realized—no sun crossed the sky; there was only constant, lingering grayness.
