AKA: New Aedius and Old Aedius.
This is going to be the setting of my comic 'The Will Letters.' The left half of the drawing is the newer part of the city, and it's all futuristic and teched out, while the right half has transformed into a polluted, smokestack infested slum over the years. The people living in Old Aedius couldn't afford to upgrade from their industrial power to all New Aedius's eco-friendly energy alternatives. Since New Aedius can't get rid of the slums and their pollution, they created a barrier of wind called The Wind Shield that surrounds the boundaries of the new city and pushes all of the smog out. So the fumes are always blowing in that direction. I'm planning on starting the story out in The Slums.
