It is no secret that Vena Ice-Free Port and Midnight City have had their differences.
Or rather, the intervention of the Judiciary has made Vena Ice-Free Port incompatible with this world.
The only link between these two human cities is their respective embassies, and they are specially targeted at their locations.
For instance, Midnight City's embassy was placed adjacent to the slums on Queen Street by Vena Ice-Free Port. Midnight City's counteraction was to put Vena Ice-Free Port's embassy on Yinhu Street—
Vena Ice-Free Port mocks Midnight City for mingling with ghosts and weirdness, while Midnight City mocks Vena Ice-Free Port for being extreme and unaware—many churches have this kind of extreme exclusivity.
The difference is that their gods truly exist.
Vena Ice-Free Port, however, believes in vain, never responding, indistinguishable "gods."
Despite their severe divergences and frequent targeting of each other's embassies, the two cities align on human interests.
