Pyrrhic city. A grey and neon bustle of tall buildings, fast cars, smoke and busy souls. Money flows in and out of it's streets like blood through veins. Business is booming, as long as your business goes through the Modacci's. A sophisticated and ruthless gang, they have their fingers in anything worth a few cents, with them you soar, without, you sink. 

Set on a world somewhat like our own, this story would take place in a city built around being strong, in a society built the same. People who can overpower others, take what they want, and really, when everyone has some sort of innate magic or superpower, everyone is fair game. 

I want this to be a busy, somewhat chaotic place. In one corner of the plot, we can see a rugged cop trying to change the city that is so far gone, being stopped at every corner with some criminal mastermind. While a few blocks downtown, a band of unlikely allies are doing battle with some eldritch demon that recently escaped it's ancient prison. 

Take an old mafia novel, set it in Gotham, and sprinkle magic onto it, and here we are. 

Anyone interested?
