The Wall is the main place where story of Cliffworld is taking place.
It is a cyclopean megastructure of the Ancients located inside a gas giant. The shape of the artifact resembles a spindle with a length of 120 thousand kilometers and a diameter of 4 thousand kilometers at the tips, penetrating the planet through the poles. The purpose of the artifact is unknown, but it gradually processes the planet's composition from hydrogen-methane into oxygen-water. One of the tips of the artifact is designed by the creators to be habitable, possessing a crust of silicate rocks at the sides, forming the surface of a huge cliff of planetary scale, and a network of exhaust holes, maintaining suitable for life concentrations of oxygen and humidity at altitudes where the atmospheric pressure of the planet is similar to 1 earth atmosphere. The estimated density of both the gas giant and the artifact is relatively low, as the gravity at the height of the habitable band is only 0.94 G. Interaction of the planet and artifact generates powerful electromagnetic perturbations that sometimes reach up to -1300nT.
