Well it's just like stuff about the world.

Like Wizards would mostly live in secluded wizard towns in rural areas. And they'd be diffrent to werewolves and possibly vampires; like Werewolves would all be on a list and have to pay to get the potion to help them not turn into a werewolf every month and their kids would have to live else where during the full moon but they wouldn't have such a hard time getting a job(though harder than non-werewolf wizards) but be paid a little less. Muggle borns would also have a harder time and also get paid less. But no one would outright hate muggleborns and werewolves it'd just be like a stereotype.

And there'd be hardly any Ghosts, like the school has one ghost and shes always sad and wishes she could just die and nobody wants to end up like her.

And American wands are made more ascetically though it doesn't make them any better wands, thats just how Thompson Rivers the wand maker makes them.

I just have all these ideas (* v *)
