Biography

In September 1993, Professor Vector began teaching Arithmancy to a new group of third-years including Hermione Granger. It was Hermione's favourite subject. One day, Ronald Weasley heard her and Professor Vector speaking about their lesson a day before, and he was confused because he knew she attended Care of Magical Creatures at the same time. She had in fact used a Time-Turner to attend her lessons.
