Planet sized cliffs, commonplace spectacles of artiplanet architecture within the "mountain" fields.

Nation-sized ledges serve as sanctuaries of life amidst the endless plummets. Entire ecosystems exist isolated on each collection of these stable grounds. Even aerial species are limited to their biospheres by giant, nearly invisible, shields of transparent xenonite. These shields retain environmental elements unique to each enclosure, such as atmospheric pressures.

To be clear, this artiplanet houses life specific to G type stars. Therefore most photosynthetics use chlorophyll or other analogues to produce a green color to absorb light efficiently. There are an innumerable number of artiplanets created to harbor life of other types of stars, in turn hosting other trending colors of photosynthetics.
