Fun idea for a muggle professor
Don’t take this seriously, it’s just a fun idea I had.
It would be really interesting (and funny) if they include a singular muggle professor to teach a typical muggle subject (like math or English, or something like muggle history). Because pretty much all the classes have to do with magic and nothing in STEM or social studies (aside from wizard history). There are plenty of muggles who are well aware of the existence of the wizarding world, and iirc Hermione’s parents even went to Diagone Alley.
Or perhaps an art class, where students have to learn how to paint without the use of magic, since spell casting can be seen as an art form.
“As you all can probably tell, I’m a muggle. I’m not sure if that word is derogatory or not but either way I’m allowed to say it. But there’s not a drop of magical blood in me. Now before you make me disappear into a hat or something, I was brought in by Prof Dumbledore because he believes there is a connection between painting on a canvas and casting spells. Honestly I don’t see it, but I don’t care because I’m being paid a fortune to teach you guys how to paint.”
