Beyond the North, Revisited

I've touched on what's beyond the North before here, and I know Matt's visited Ravar in his tabletop game.  However, as I was recently outwitted by a player and may be forced to flesh out more of the world, I thought I might as well share it here, for the educated players to see.

As previously mentioned, there are established names and identities for both the Merov Duchies and the lands the Kraki have conquered.  The Merov Duchies of Cutane, Naever, and Burgen all have their own identities, and it might trouble some to note that in many ways, they're more Vincian than Vincia.  Additionally, the Hess, Tets, and Thars... all conquered by the Kraki... are somewhat similar to the Kraki (and thus the Heorots and the Guth, who are all cousins), as well as their Lorn neighbors.  To provide a little details on these places, beyond simple names...

• Cutane is the Duchy that borders the Protectorate of Timber, and is thus the most heavily influenced by the Faith (and probably the most advanced, technologically).  They're also the least centralized of the Merov Duchies, with the Duke of Cutane far weaker than his peers.
• If the Duke of Vincia rules through political manipulation, the Duke of Naevar rules through force.  His power is nearly absolute, and his court is a rigidly organized bureaucracy.  However, his power is curbed by the fact that Naevar is the smallest of the the Duchies.
• The largest Merov Duchy is Burgen, which is also the most influenced by their neighbors.  Burgen is, by Merov standards, barbaric (although this still makes them far more refined than the Heorots or Kraki) due to the influence of their Rav and Tet neighbors.  They are the largest and most populated of the Duchies.
• The Hess are a conquered people of the Kraki, and dwelt in a lowland forest close to Guthlund.  They were a very war-like people, with very little central organization, and although they fought fiercely, they were easily defeated in small numbers by Rolf over the course of two years.  
• The Tets were a people much like the Kraki, heavily influenced by their Merov neighbors, who conducted trade (and raids) along the rivers of the continent.  They were the first land to be conquered by Rolf, before he turned his eyes toward the County of Pendrose in Vincia.  After Castus' intervention, Rolf looked at his other neighbors.
• A mountain-folk, the Thars were intensely hard to subjugate, and the area was in a limited rebellion up until the day Rolf died.  Because of it's geography, the trouble Rolf had with the Thars prevented further conquests.
• Protected by narrow mountain passes and high altitude, the Lorn are an isolated and strange people, early converts to the Faith of Arim, and for some time an island in that Faith.  Dedicated to maintaining their homeland, the Lorn have perhaps the strongest cultural identity in the known world.

Having given some detail on these people, I feel a bit more comfortable teasing out the other major peoples of Arimdom... What must be known is that the greatest "nation" (an anachronistic concept used carefully) is certainly the Protectorate of the Patriarch, which is centered around Tiber.  To the West and South of the Protectorate, along the sea that defines the continent, there are a collection of cultures that all speak a dialect of Albers.  The Albersians are not a people but rather a group of people who practice a more advanced sort of feudalism, and are generally continually at war either with each other. Finally, there are the Rav, who control a very large territory but have a relatively small population density... largely as they are on the edge of civilization.  Beyond Rav is the forest primeval, where dark and strange things (perhaps even stranger than in Lloegyr) lie.
