From publisher blurb:
This is a new campaign setting that can be used with virtually any fantasy RPG system.
Corsairea is a city built by, and run by criminals. It is a place where danger and secrets hide behind every corner. This is a place where characters go to find that rare (and often illegal) item they’ve been searching for. This is where thieves and rogues go to hide from the law. This is the city that looks the other way on pretty much any activity.
Essentially, it is a city where your party can find a lot of fun and adventure.
Included in the book are pages of history and lore of the city, dozens of NPCs to inhabit the city, laws and things to watch out for, as well as several adventures (written for 5e) to get the ball rolling on this setting and to introduce your players to the world and characters that inhabit this fair city!
