Revolution
The Gultic Conflicts mark an extended period of rivalry and war between the modern-day protectorates of The Protectorate-Commonwealth as well as city-states of The Forsmarch.
Borders shift constantly, and counties and duchies are destroyed, reformed, or built atop regularly, and there's significant overlap between the Conflicts and the Freijäger Uprisings. This ends with the Confederation of the Protectorates.
