On the subject of all this geographic systematization...
When I created my characters, I deliberately left their geographical backgrounds vague. Scorpio at the time was working on a map, and I figured every new location named in a character's background only complicated that task. At the time, I figured I'd wait until the map was ready and figure out where my places would best fit in.
Scorpio quit LEW before finishing the map, so I figure there's no point waiting. Now Jo Guilan's background isn't an issue. All I have in mind is that he's from some wooded area. So if he ever comes back into play (unlikely), I'll pick a spot. Nurlan's is more of an issue. I envisioned him as coming from a large empire. It doesn't really need to be an empire; a confederacy would work just as well. But in the original background I called it an empire. I didn't name it, although I did name the capital city.
What I was aiming at was a region large enough to have very diverse cultures, including diverse musical traditions, but considerable trade and travel within the region. I envision that nobles in the various provinces often host musicians from all over the empire, and travelling performers often do a circuit of festivals all over the realm. I want a boy who's been "adopted" by a respected musician to have a chance to meet other musicians from all over, learn the songs and varying musical styles of a fairly wide range of cultures. At the same time, I want this to happen mostly within some well-defined region, so that When Nurlan first came to Orussus, he was going a step further.
Now to the best of my knowledge the only empire identified as such so far is the Carduthian Empire, another creation of Uriel. He had plans for it. From what he tells us... it might fit the bill above, or might not. He's described it as a military powerhouse. Hostile to its neighbours... its borders are probably not often crossed peacefully, but within the empire internal travel is another matter.
Given that Uriel has not been around for a while, that the Carduthian Empire is a country whose capital so far has no name, and that Lhondaio is a capital whose country so far has no name, would it be OK to decree that Lhondaio is the Carduthian capital, and that Nurlan's boyhood travels with his mentor Shkarna were around the Carduthian Empire?
