It also makes Skye's reasoning all the more right and, believe me, you won't like it when he's right XD 

Since magicians are smaller in number, am I to assume that there will be a time when there will be a ban on making magician characters? It seems quite reasonable to try to even out the numbers at some point. Also, can we really switch between calling magical users magicians and mages? I agree that the two words are synonyms, but what is more commonly used in the kingdoms or does it vary from country to country? 

And another thing, could you tell us what kind of culture all the kingdoms come close to? Ferros is a bit Nordic and Kain is a bit Arabian. What about the rest? Can I try providing some pictures for them?
