The northern along the coast and riverside, is where the majority of the population is located. The south is far more difficult to govern, with frontier towns that are only barely recognized, in some cases not even mapped out in the official ledgers. The pro of this of course that the tax collectors red horses are never seen, lest they waste their time taking money from those who have none. The negative is that without any sort of organized military presence, the towns in the south are left to fend for themselves with bandits, monsters, and God's know what else.
