That is one thing you do need to be aware of, the world of Ærth is not our Earth. It has a different history, it has a different structure. Heck, to some extent it has a different physics which allows for things we can't have. And one important difference lies in just how long the New and Old Worlds have been in contact.
In our case contact between the two worlds goes back some 1,000 years, to the arrival of the Norse in what is now Canada. On Ærth it happened about 5,000 BAF (Before Atlantl's Fall), our 4,000 BC. People have just had a longer time to get used to the idea, and to move around from world to world more often and with greater facility.
Falcondonia in Vargaard for example started off as a Frankish colony around 125 BAF (our 875 AD), around the time of Charlemagne. At present she is a French duchy, though she amounts to a grand duchy and is in negotiations for independence and the status of monarchy. Which means that Pequot and Massachusetts nobility are part of the Parisian court, with the royal family having Wyandot relatives.
As a result the various populations are more mixed than they are here, and that the Skraelings (as they've chosen to call themselves) actually have a greater population and greater power.
Recently Iroukia took in British and Tuatha immigrants with the decision of the French government to expel those populations then living in Falcondonia. In fact, the Tuatha are now one of the nine lodges of the Haudosanee, and the British are petitioning to become the 10th. As you can see, it's not your Earth.
So keep this in mind as I write more on Ærth.
