As it is often convenient to take a certain place as a focus in creating a setting, and because this particular locale is one of the most notable and prominent places in our world, it's time to talk about...
The Great City-State of Kadessa
South of the Sighing Mountains, on the coastal plain known as the Trodanis, the vast, ancient, and glorious city-state of Kadessa sprawls across the land where the River Troda flows into the Gulf of Arms, a monstrous nation-city of brick, marble, wood, iron, and glass, with a population of millions. A mighty commercial power, Kadessa's fleets sail to trade with far-away nations across the oceans and up and down the coasts and rake in wealth from numerous colonies and tributary city-states. Under the rule of the glorious power of the Empress, the wisdom of the Senate, and the protection of the Kadessan militia, the people of Kadessa take for their symbol the Three-Headed Eagle, each head respectively representing the Senate, The People, and The Imperial Throne.
But all is not well in Kadessa. Beneath the glittering veneer of imperial power and wealth, the City of the Three-Headed Eagle seethes with corruption. An immensely-crowded, roiling polity, the city's huge, poor underclass is ruthlessly and indiscriminately oppressed. Crime levels are astounding; an extreme level of casual violence is a striking characteristic of the world of the common Kadessan. An anarchic and shockingly-violent underworld of criminal mobs and brawling street gangs parses out the districts and neighborhoods of the city, battling amongst themselves and with the state militia. Demagougic guilds and worker's unions arouse great riots, and even greater spontaneous riots are a near weekly occurance.
The Senate is nothing more than a meaningless, powerless old boy's network in which back-slapping aristocrats and scheming compradors play at leading the state and claim the "mandate of the Kadessan people". The Empress, though effectively ruling by decree and unrestrained by the Senate's noble pretentions, lives a decadent and gaudy life of illusion, carrying out nothing more than the hoary traditional rituals of the state autarch and drowning herself in excess. The state militia is forced to rely upon more and more brutal methods of control and suppression to control the riotous and violent populace, and enlarge their own power. The true power in the city is a secret council of hidden individuals and representatives of powerful factions.
And yet, this roiling stewpot of intrigue, violence, power, glory, oppression, and resistance remains a mighty power, with great influence, which maintains a large flock of colonies and tributary states and territories from which it draws it's wealth, in addition to the trade that swells the city's veins like lifesblood.
