I think that our technology and the Rac Cona Daimh's technology (and/or magic) are quite similar.
I'ved noticed that they can do many things that we do, but much more efficiently. Take their glowing neon signs, for instance. Both technologies deliver the same results, but they do it without a funny-shaped glass bulb or copper wires to power them with. The Luxfont building may be big, but comparatively I think it's pretty small for something that would power a large city and surrounding towns. I think that their "magic" saves them from the overhead cost that we have, and thus prevents waste.
On the other hand, we're already able to do most of the "magical" things that the Rac Cona Daimh do, albeit only in high-powered laboratory settings in some cases. For example, I went on a tour of the
National High Magnetic Field Laboratory, and there was lots of stuff there to make you go, "Oooooooh! Aaaaaaaah!" Our doctors are able to "kenn" a person using an ultrasound or an MRI machine, and they can use a machine to focus ultrasonic waves to break up kidney stones, for instance.
So, what does this all mean? Well, in a word... nothing. As Mr. Ralph pointed out, I think that high-tech toys are cool, but they aren't the most important thing for a society or for life in general. ("If I have faith that can move mountains, but have not love, then I am nothing.") I think it just means that people are people, whether they drive cars and use computers, whether they ride in horse-drawn carts and use abacuses, or whether they ride around in Luftships and are covered in fuzzy fur.
I think any such cooperation would probably have to be initially established through the respective Churches -- given that having a similar faith is the sole thing that humans and Rac'Cona have in common culturally. In light of that, initial efforts would probably have a large humanitarian (Rac'Conatarian?) slant (comparing notes on medicine, etc), and would gradually branch out into the commercial once citizens from both sides got comfortable with the other species.
I think so too. When I daydream about visiting the Rac Cona Daimh (especially in a scenerio when I'm not already familiar with them and with Lux), I find myself drawn to a local church and to someone like Brother Linnaeus.
) by trading with the Rac Cona Daimh. What sort of things would be especially valuable to the Racconans? What sort of things would be especially valuable to us?
