Something to add for flavor:
La Cour Des Miracles
It existed during the 16th-18th centuries, here in Paris (France). There was a huge number of destitutes and beggars at the time. In Paris they had taken residence in a certain district all around a place called "La Cour Des Miracles", which can be translated into "The Miracles' Court." The place had got the name for at night all the destitutes lost their infirmities and became normal again, up until the next day when they would resume their fake ailments for begging purposes. Paris' organized crime was located in this district, and its inhabitants had even elected ther own king (the Thieves' Guild's master?), in mockery of the true king of France. Eventually, this was seen as a real threat against the monarchy by the government, which sent the army to eradicate it. Buildings were burned, and up to 60,000 beggars and destitute were finally sent to the galleys (after having been marked with red-hot iron on the skin).
