Ba Sing Se

Ba Sing Se is Earth Kingdom’s capital and biggest city, due to the safety it has thanks to its two impassable walls(after which the city is named Ba Sing Se, the Impenetrable City), which become useful during times of war such as during the conquests of Chin the Great. During the 43rd Year of Avatar Kyoshi, the city suffered from a peasant rebellion that led to the creation of Dai Li.
