Hearts and Pistons
There is not much of a natural world left. What does remains is often small green spaces in each city. More often than not these areas are infested with the homeless. The city of Fahd has a carefully preserved and magically maintained central park running the axis of the city. The park is large enough to have its own ecosystem, but it is also a place for crime and criminals.
The only weather to exist naturally in the world are the swirling winds that signify the change of seasons. It gets cooler in the winter, sometimes below freezing, and hot in the summer, near 90. Magic simulates rains showers from time to time.
