Hmm. Okay, so the realm of fire is, in a sense, in the northwest (behind a magical wall). So, if the sun god strays toward the fire realm, will he visibly look as though he's in the northwest sky?
Meanwhile, if the wind god strays toward the realm of air, would it seem as though the wind blows to the northeast? And the earth, meanwhile, is turning toward the southwest, correct?
Basically, if we can surmise that this straying occurs in regular, seasonal patterns (and if these observations are accurate), we can say something about the way heat and moisture is distributed throughout your world, and thus something about the climate. If it's really just completely random, it might be more difficult to make these sorts of educated guesses.
Another quick question: assuming the sun starts in one side of the world each day and crosses toward the other, how does he get back to his starting point each day?
