Wadesdah is the capital and largest inland city of the fictional nation of Khemed It is first described in Land of Black Gold. In the 1950 version of the aforementioned work Wadesdah was described as just a small rural town but in the 1972 version, it was rewritten it was changed to become Khemed's capital.
