Cities are the backbone of your Kingdom. Here you can train units and build improvements, though only one unit or improvement can be constructed at a given time. The speed at which you train units and construct improvements increases as your Production gets higher. You can increase your your production by building Improvements, growing your population, and claiming Clay Pit resources. If you would like to see more detailed information on your city, including yield, income, and production breakdowns, click its medallion or the "Details" button to open the city details screen.
