Prompt: The edge of the city is an abrupt cliff-like wall of haphazardly stacked container-dwellings, which shifts from time to time to keep up with the strain of its own weight. Then, there is nothing but barren and fetid marshes as far as one can see. On the horizon, when the sun comes up through the haze and the smog casting a rusty red glow over everything, one can see distant trees clawing and grasping toward the sky. In the city, columns of steel and stone rise above the scattered tenements: ancient spires of terrible majesty dominating the urban landscape, between them narrow catwalks bridging dark chasms.
