After the initial ambassadorial contact.... well, from that point things sprawl out into countless threads.
The racconans would be initially delighted to learn that the surrounding "kingdom" was actually a constitutional republic, much like their own.
They might not be quite as pleased once they start getting access to human mass media.... and start getting a picture of our current state of sociopolitical affairs. There would also be some serious "rough spots" where America's culture and their own would clash.
Keep in mind, Racconan society is much more libertarian than our own on some points--- much more conservative or traditional on others. They would be bewildered by our political correctness codes, for instance. They would be horrified by our abortion industry.... and their politicians would start to have serious problems with our increasingly hypocritical society--- one that gives rights with the constitution, and violates them with the courts (free speech on one hand, yet PC codes, FCC regulations, and campus speech codes on the other; Private property yet unrestricted asset forfeiture and eminent domain; abortion and euthanasia for the innocent yet anti-death-penalty activists for murderers; We Support the Troops but we'll sabotage their mission...)
Meanwhile various segments of our own culture and government would be having conniption fits over their current bumper crop of hemp, their universal right to bear arms, their lack of a "proper" public school system, and their (from a politician's perspective) woefully under-regulated medical, agricultural, and pharmaceutical industries....
Imagine how spazzed they'll get when they find out about the Biomancers.
To say nothing of the hierarchial complexity of dealing with not one, not two, not three,not four, but at least FIVE different sapient races already known to live in the Seven Villages.... The Racconan, the Gragum, the Dryads, the Gnomes, and the Bogies. The rather intricate synergy between the races would be a bemusing phenomenon for the human ambassadors to try to grasp.
The open religious influence on their society would have certain people chasing their own tails ("how can we insult their 'jesus freaks' without being ethnically insensitive, Buffy??")
The theological response would range-- well, about like always-- from denunciation to shoulder-shrugging acceptance to attempts at comparitive theology. The similarities between Sojournerism and evangelical christianity would delight some, while others would repudiate it as wishful thinking....
And the environmentalists will be absolutely, utterly FREAKING.
