Dyvers is a land of refugees. In the build up to the Greyhawk Wars, and through their conclusion, the city of Dyvers brought in more than 50,000 refugees who have continued to live there since.
There are two ways that you can play this out in your home games. On the one hand you could have the refugees struggling to fit into the city. OR, and I encourage you to play this way, you could have the refugees thriving in the city and making it their own.
You can clearly see how I would go.
