Perhaps I'll add it to my list. lol
I'm more into Summerian and Ancient Egyptian culture atm.
And curious about the Comanche's. Which apparently has a pretty fearsome reputation. ^_^
(The kind that makes your villain looks like a fluffy kitten by comparison. Based on things they actually did do.)
But I understand your artistic vision.
And while I am studying various cultures for one of my stories, I mainly focus on whatever is the closest to an evil overlord in them, because I have an idea for a reincarnation story where Harry Potter is the reincarnation of someone who's first life (that he remembers) was that someone who rose up to rule the city of Ur (or Uruk, haven't decided) with an iron fist... and he gets progressively more wicked over time. With his most recent incarnation before Harry Potter being the infamous Nightstalker. ^_^
(Which fits his satanic leanings. Although the entity he worships is much older than any biblical Satan of course.
It's time-taking research.)
I think that if I get around to write a fanfic of your story, it'll be the nicest version of Harry Potter in ANY of my works. lol
(Partly because he's raised by a villain in all but one of my other works, and in that work he's dating Jeff the Killer. lol)
And I like staying as true to the original works as possible, changing only minor details and using Chaos Theory to calculate (or estimate) the effect of those minor changes.
