There was a city on a plateau that became a very pointed cliff overhang on one side. Passing through that tip was a massive tower, which appeared to have been assembled randomly. It was dotted with doors, staircases, pillars, all kinds of things, made out of all kinds of materials. The town was much the same, though generally made of wood and ropes and things. Had the feeling of a desert island home built from flotsam and jetsam as seen in so many castaway movies.
