New orleans has completly sunk into the groung, on its ruins, sunken Orleans was built. Its shanty houses are lifted 10 feet on stilts above the swamp. A loose system of government, with no law enforcement, oversees the trade that does makes its way through. It’s a melting pot of many diffrent cultures and technologies. The Black Nation makes regular gasoline stops here.
The city structure itself is weak, any blows to a stilt might bring it down. Also, the bridges that connect the houses and buisnesses toghether has also seen better days. Below, feeding off of the scraps of humanity, are all sorts of mutated wildlife. This makes a slip off the scaffalding very hazardous.
However, living “peacefully” with the swamp around Sunken Orleans are all sort of local folk of many diffrent races. All are supersitous in someways, and have very traditional, low tech lives.
