a concept painting of the Dark City as I’d intend it to appear in the Changeling AU (this was originally supposed to be more illustrative with Terra and aqua in the unexplained blank spot in the street. that got scrapped though)

basically it’s both an imperial capital (with the castle being the base for the government and militia, there isn’t much of a difference) and a tourist destination; the bottom city’s state of perpetual darkness gives it a perpetual nightlife that can be sort of disorienting
