Notes about the maps:
The maps in the Atlas are meticulously researched in the Harry Potter books. In some cases, actual maps of real places are used as reference. But these maps are NOT canon; they are essentially fan art. There is no way to draw maps of anything from a book and have them be 100% accurate. They are as accurate as I can possibly make them with the information available. I have included lists of references from the books below many of the maps so you can see why I made the choices that I did.
