Here's the thing. If you are looking for a campaign setting where everything that has ever happened is minutely reported and where every meter of the world is accurately described, this is not the book for you.

Krevborna is presented in a very particular way, letting you get a really good idea of the main themes and atmosphere of the setting, while being vague enough in the small things in order to easily let you come up with your own stuff. Other campaign settings tend to drown you in details like dozens of dates, gods and other stuff, often limiting your imagination in the process, while Krevborna strikes a balance between being both flavorful and inspiring at the same time.

This is a setting meant to be played, not just read about.
