Professor Bigby is a Pixie that taught a course centered around Battle Magic at Brakebills from the 60's to the 90's, but stopped as requested by the High Council, due to the high mortality rate that occurred in that course. She was in a relationship with him at the time, and her knowledge turned out to be very useful to defeat The Beast.
