Messer City is not well-known within the Federation, but it's quite something in Secret Phoenix State.
Besides its long history, it is also because its several districts each have their unique characteristics.
Naturally, there's no need to mention the prosperous Central District where the most famous banks and companies in the southern part of Secret Phoenix State are located, and Midtown Avenue is even known as the must-visit shopping paradise in the southern Secret Phoenix State.
Then there is the Blank District, even though it is messy, filled with refugees, rampant with gangsters, and everywhere there are illegal constructions, the environment is layered like an ant nest, with a clearly defined law of the jungle, all giving it an oddly beautiful aesthetic.
Thus, it became a favorite shooting location for many movie companies when making films with a dark style.
