The harsh and difficult-to-navigate region north of Cen and Chevell. A lawless wasteland where anarchy reigns and hundreds of tribes fight continously for influence and dominance. Some of these tribes are so exotic that they don't recognize neither Ardia nor Versa as gods, but have entirely different pantheons instead.
Many voidtouched who seek to live their lives completely free from state control seek to escape to Heretic Mountains. For better or worse, those who succeed in doing so are usually never heard of again.
Relationship with neighboring nations
There is a wordless mutual understanding between the tribes of Heretic Mountains and its two neighboring nations for centuries: as long as the people of Heretic Mountains don't intrude upon the territory of Cen and Chevell, they are left to their own devices.
Cen and Chevell have no interest in spending resources to conquer Heretic Mountains, because the land there has very low value for agriculture and the region is notoriously difficult to invade, and very easy to defend. The region is rife with ambush points, narrow canyons, passageways and bridges that can be easily sabotaged. Moreover, dangerous and unpredictable magic users can be found everywhere.
