Filthy Jade Palace had appeared a short time before the appearance of the alien civilizations. Before that, the Core was as unruly as it could get, and no one could claim superiority in the underground city. As it was disconnected from the main district by a long distance and by gigantic walls, the police never managed to claim control of the area, and neither did they ever truly try. This left the shady area of the city in a constant troubled state. Gangs and small organizations controlled streets and hoods, yet no one had ever managed to subject them under a single crown.
