Most cities have their own protective spirits. Citizens worship their city’s spirit to keep it strong and healthy, for it is the soul of the city.
The city god is usually represented by an idol fashioned as a typical wealthy native of the region. If the area is of mixed ethnicity, the idol is usually shown as a member of the current ruling class.
For an example of a City God, see the Cult of Pavis in Pavis: Gateway to Adventure page 361.
