Professor Septima Vector (fl. 1974 – 1996) was a witch and Professor of Arithmancy at Hogwarts School of Witchcraft and Wizardry from at least the 1991–1992 school year. She may have also been the Advanced Arithmancy Studies teacher.
Professor Vector was known among students as a "really strict" teacher, so much so that some pupils were unsure whether to take her classes. She was also known for giving her pupils plenty of highly complicated and difficult homework. Her subject was Hermione Granger's favourite subject while she was in school, but one of her roommates did not like it because she found it too difficult.
Nothing is known about Vector's early life, though she likely attended a wizarding school such as Hogwarts School of Witchcraft and Wizardry and excelled in Arithmancy, and may even have taken Advanced Arithmancy Studies.
Career at Hogwarts
At an unknown point in her life, Vector accepted a teaching position at Hogwarts School. She became the Professor of Arithmancy, being given Classroom 7A on the seventh floor of Hogwarts Castle to teach her lessons in, and presumably an office elsewhere on the school grounds. Her relationship with the rest of the staff is unknown, though she was considered very strict and old-fashioned by some of her students, so she may have been like Minerva McGonagall in personality.
Another class, called Advanced Arithmancy Studies, was known to be taught at Hogwarts. It is likely that Professor Vector also took this class. The Advanced Arithmancy Studies classroom was located on the first floor of Hogwarts Castle, in the Turris Magnus.
In the 1991 Start-of-Term Feast, she sat next to Keeper of Keys and Grounds, Rubeus Hagrid. She listened attentively to fellow Professor Minerva McGonagall, who was telling the first-years how the Sorting ceremony would proceed. She also witnessed as Harry Potter was sorted into Gryffindor House.
In 1993, Hermione Granger began studying Arithmancy with Professor Vector and excelled in the class. After one lesson, they had a talk about their lesson the following day, which Ronald Weasley overheard, and was confused, as Hermione had Care of Magical Creatures the day before, and so could not have been in Arithmancy. In reality, she had been using a Time-Turner to get to all her lessons.
On 2nd September, 1994, the first day of classes of the 1994-1995 school year, Professor Vector did not give her fourth year students any homework, an unusual occurrence, which Hermione Granger mentioned after Ronald Weasley told her that he had had a lot of homework. She was also presumably present for the arrival of the Triwizard Tournament participants, the Yule Ball and the memorial feast for Cedric Diggory at the end of the year.
Professor Vector was once again teaching at Hogwarts in 1995, where she was present at the Start-of-Term Feast. When the new DADA teacher, Dolores Umbridge, rudely interrupted Dumbledore to give a speech, Professor Vector and her colleagues were stunned at her audacity. Like her student Hermione Granger, Professor Vector and the other teachers understood the true gravity of the speech (the Ministry was interfering at Hogwarts) and did not clap when Umbridge finished her speech. Professor Umbridge was later appointed High Inquisitor with powers to inspect and dismiss teachers she felt were not up to scratch (or rather, those that were loyal to Dumbledore). Professor Vector's classes were presumably inspected, but she likely proved to be a competent teacher as she was not dismissed or put on probation.
When Rubeus Hagrid returned from a mission given to him by Headmaster Dumbledore, he had a conversation with Harry Potter, Ron Weasley, and Hermione Granger, Professor Vector walked past them and was almost knocked off her feet by Hagrid. As she was passing them and they were entering the Entrance Hall, she had presumably come downstairs to the Great Hall to eat.
Later in the year, Umbridge became Headmistress after Dumbledore was ousted from Hogwarts, but Professor Vector and her fellow staff members did nothing to help her and instead found means of annoying or hindering her. Indeed, when fireworks went berserk all over the place and a corridor was turned into a swamp (both times courtesy of the Weasley twins), Professor Vector did not attempt to remove either obstacle and took great pleasure in having the Headmistress run all over the castle getting rid of escaped fireworks in the classrooms. When Hogwarts was restored to normalcy and Umbridge was ousted and pursued from the premises by Peeves, Professor Vector and the other teachers did nothing to halt the students from chasing after her.
1996-1997 school year
In 1996, Hermione Granger thought she may have made a mistake in her homework and visited Professor Vector to discuss it.
It is likely that Professor Vector participated in the Battle of Hogwarts in May, 1998. Her later life is unknown. If she did participate in the Battle, she presumably survived, as her name was not given among the Fallen Fifty.
She often wore red robes with a matching pointed hat.
Personality and traits
Professor Vector was described as very strict by a student who was not sure if he should take her lessons. She was also said to have given out masses of complicated homework to her students, who were all third years or over, though appeared to be rather sociable with the other teachers. In addition to her strictness, she was shown to be a competent and skilled teacher, as her lessons passed inspection by Dolores Umbridge; furthermore, she taught Arithmancy for at least six years at Hogwarts, proving her competency and experience as a professor.
Magical abilities and skills
- Arithmancy: Vector was a highly accomplished Arithmancer, teaching the subject for at least six years, showing her expertise in this very difficult and complicated branch of magic.
- Charms: Professor Vector was capable of conjuring a non-corporeal Patronus, which is a mark of superior magical ability and skill.
Septima most likely comes directly from Latin Septima which translates to "the seventh" (female form). As seven is the most powerful magical number, and Arithmancy deals with the numbers appearing in magic, this name suits the character well. A "vector" is a concept in physics and mathematics, specifying a quantity that has both magnitude and direction, and represented by an arrow.
Behind the scenes
- Professor Vector was played by actress Hazel Showham in the the film adaptation of Harry Potter and the Philosopher's Stone, appearing as an unnamed background extra. In an instance of additive retroactive continuity, the physical appearance of this extra was later used to depict Vector in LEGO Harry Potter: Years 1-4.
- In LEGO Harry Potter: Years 1-4, Septima's character token can be found in the Tom Riddle's diary level. This may indicate she already worked at Hogwarts in the 1940s. Other characters' tokens can be found in matching places, i.e. Minerva McGonagall in the Transfiguration classroom; however, there is another possibility that Septima's token location has no particular meaning.
- Professor Vector's first name only appeared on a list of the Hogwarts professors which was released on J. K. Rowling's website.
- Originally, she was a male named Septimus and her last name was intended to be Vecta.
