Sureth City is a huge city located in northern Tezen. It's one of the largest cities in the Pokemon World, being only marginally smaller than the colossal Castelia City in Unova. It is the financial, and official, capital of Tezen, as opposed to the cultural captial, Zertinan City. It's located on the site of an extinct volcano, and the city uses the heat from the caves underneath the city as energy. Power is also a major export of the city to the rest of central Tezen.
