A couple quick thoughts (addressed to everyone, not just Sili):
If the North is supposed to be more orderly, that would mean that both the Trow and the Berserks would have to be orderly people in the extreme. I'd buy the former; the latter I have a little trouble with. Again, in the south you would have chaotic ghols and dwarves. Hmm. The south seems to corner the market on technology (though the Trow were the first blacksmiths...). Would you suggest that comes from the creativity of chaos or the stability of an orderly society? Seems to me it takes a little of both.
If it's evil to the east, good to the west, then is Muirthemne more evil than Madrigal? The avatara better people than the heron guard?
The problem, as I see it, is Brownian Motion. You seem to suggest that there's some kind of influence pulling on people in every corner of the world. Yet the mythworld is famous for its _lack_ of geographical segregation--the various races are quite mobile and cultures are radically mixed. If you think of mythworld people as particles of order/chaos/evil/good, they seem to have been mixed very well--like pouring cream and sugar into opposite sides of a cup of coffee and then stirring it vigorously with a spoon. After a while it's impossible to say where the cream was added and where the sugar entered. Even the untamed lands have been contaminated (specifically by Damas). Do people bring their tendencies with them, or has the Mythworld been mixed enough that such polarities are no longer noticeable?
The obvious exception is Faraway, which, as far as we know, has only been seen or at most visited by a handful of mythworlders, and can therefore be as good or evil as it wants to be.
