In all seriousness, this is what happens when you write novels without doing any world-building and just put down whatever seems “fun”. The are sooooo many things in that series that make no sense once they are superceded by later plot devices. Rowling didn’t think any of it through ahead of time and gave almost no thought to internal consistency with previous content when she wrote new things.

It’s honestly a terrible series in most regards and it’s kind of disappointing how popular it became.

Also she a trans-hating bigot. Fuck J.K. Rowling. Can’t forget that part whenever discussing her or her work.
