Rivers
Rivers
Traditionally, cities have been built along Rivers, and for good reason. Rivers provide fresh water for people to drink and irrigation, improving the farmland around the city. They also protect a city, as it is quite difficult to mount an assault against a city across a River.

Rivers block Zone of Control from all units.
