Novia Proxima
The tallest city of them all, Arcturus has been here since the very beginning. The first city to be built, and a place of refuge for many during the apocalypse - Arcturus is the most crowded city of them all, and the most polluted.
With nowhere to build but upwards, thats exactly what Arcturus did. Instead of being laid out, the city instead is built upwards - city districts being ruled by height instead. Laying at the top is the Sunlight Towers, then descending downwards is the Twilight Avenues, all the way down to the Midnight Streets. Rich, to poor, to uninhabitable.
Well I'm just fine, thank you very much. How about yourself?
A level of class is kept in Bellatrix that is practically unnatural to the neighboring cities. A family town - even at the size of a city - leaves many puzzled. But somehow Bellatrix does it just right, with a perfect ensemble of politeness, subtle passive aggression, and a love for bake sales - Bellatrix is about the only thing left of what was once known as the suburbs.
Bellatrix also has a neighboring town, Costella Countryside. A smaller, and more closely knitted community, its about the only part of the world that could be labeled the "south" anymore. Unlike most cities, especially its parenting city Bellatrix, Costella does not rely on technology.
Capella, the city that abides on the coast. Surviving, but just scraping by. One of the poorest cities of them all, and a crime rate that could battle Hadeus' some day, this cities roads are cracked and flooded with potholes, beat up cars, and citizens that often look at you with half lidded eyes and a frown creasing their face.
