Silver Marches

From NWNWiki

The Marches is a vast region of northern wilderness more commenly called the Savage Frontier. It is home to a small number of large, well-defended cities and many smaller, but no less well-defended, towns and villages. Citizens of more "civilized" lands in the south consider it a wild land of barbarians and monsters. Those who call it home consider it a land of great promise and beauty, but even they do not deny the hazards posed by the harsh climate and countless monsters.
