Septima Vector

Next in the ‘minor/underrated Hogwarts staff’ is Septima Vector and boy, does she deserve her place in this fanart series!
Vector teaches Arithmancy, which is another of the elective subjects offered at Hogwarts that Hermione took during her 3rd year. The only things that I can recall is that Vector is considered a strict teacher and that Arithmancy is a complex and difficult subject.
Once again, bless you Hermione Granger and your nerdiness cause otherwise we wouldn’t have known about this class either…
