I added this story to my favorites I admire your creativity, that you put your speculations into narrative form. I have also speculated on Magical Native Americans when trying to compile a history of Magical America, but admittedly did not come up with much, and what I did have was a more. . .optimistic view, I think is the word for it. I hope you continue the story.

what does this one shot have any thing to do with harry potter?

This is an interesting short story, if it's a one-shot, but I don't see any immediate connection to Harry Potter, since the references to magic are very vague. If you planned to continue this, though, I'm interested.
