Ba Sing Se is the massive capital of the Earth Kingdom, where it encompasses nearly all of the northeastern corner of the continent.
The city is by far the largest city in the world, essentially being more of a small country than a mere city. Ba Sing Se means "Impenetrable City"; the city is so named for its world-famous walls, the gates of which have no hinges or other hardware, and are opened by use of Earthbending. Behind the Outer Wall lies a large expanse of farmland, Lake Laogai, and several mountains. The Inner Wall encloses the city itself. The city is also notable for having a unique system of dividing the populace into different parts of the city based on social status.
Early in its history, Ba Sing Se was once simply a small subterranean city carved out of rocks by Earthbenders. As the benders further excavated, they came across beautiful illuminated crystals and began to mine them. The crystals currently serve as a common light source for Earth Kingdom inhabitants. Eventually, as the metropolis' expansion reached above ground levels, the catacombs were abandoned.
