A long time ago, someone once asked me about North American fairies, and whether working with them would be different than working with, say, the Brownies, the Sidhe, the Seelie and Unseelie Courts of Great Britain and Ireland.
I can now say that working with the Immortals of North American would be greatly different, in the sense that: you would not be working with them. From what limited knowledge I’ve gathered, they come to you. Whether to play or prank or help, they seem to choose to come to you by their will alone.
There are countless stories of the Nûñnë'hï both existing with and assisting the Cherokee people, one of the most well-known stories being about how they fought alongside the Cherokee when their land was invaded by a powerful, unknown tribe of Native Americans from the southeast, at Nikwasi. Another being the many ways these Immortals aided Cherokee people by inviting them to live with them in the mountains to escape the genocide and relocation they would inevitable be forced to endure.
Of course, these are not the only kinds of Fae living in America. There must be thousands of stories and mythologies spanning countless generations of Native Americans.
The Immortals are bound to the people of America as the the Fae are intrinsically tied to land of the British Isles. As a UK native, I have absolutely no authority on advising how to act in the presence of the many, many races of Fae that inhabit America, but I implore each and every one of you to look up and explore the enrapturing and incredible stories the internet supplies on the American Fairies.
