The Wilderlands
The Wilderlands is a generic term for all the land and civilizations between the 10 Nations. It is a hostile environment filled with extremely dangerous individuals and organizations, and settlements are few and far between. The oppressed populations freed during Kadamitas found their peace in The Wilderlands, and relish in its anarchy.
Anyone seeking to pass between The Wilderlands from nation to nation must be extremely careful in doing so, as a single misstep could instantly kill most anyone. Outside of the pre-established, heavily guarded, trade routes, The Wilderlands is completely unsafe and without law. Any who wish to hurt will do so without repercussion, and it's dreadfully easy to die in a place as lawless as The Wilderlands.
The Wilderlands is home to many a ruins and long-forgotten artifacts due to large portions of it being the previous land of the 5 Powers of Old. Felesvollr in particular is adept at stalking through The Wilderlands undetected in search of long lost knowledge left from those before.
