The City of Uris, heart of the Fedou region, on the planet Theonia, is, not just a city, nor large, huge, but a city so great it has its own space program, and produces 7,550,050kw of energy. The city has an airport with 5 runways, and so much industry its hard to count, there's literally multiple highways full of juts nothing but industry on the side, HIGHWAYS WORTH OF TRUCKS, Bumper to bumper. 

Oh yeah did i mention it produces no water and is completely reliant on a much smaller city for it?
