Ba Sing Se

Ba Sing Se is one of the central locations of the television series, Avatar; The Last Airbender. The capital city of the Earth Kingdom, covering much terrain of the nation's northeastern coaster, Ba Sing Se is arguably considered as one of the largest cities of the Avatar universe, followed by the Fire Nation Capital City, essentially being a small country, rather than a large city. It is also featured in the Non-Disney Villains Tournament, as one of the central locations of the series.
