Tabia Nimr

Tabia Nimr is the President of Heka-Aaru Academy of Magical Excellence. She and Rebecca Proctor were classmates at one point in time, and are best friends. She is also aware of Rebecca's efforts to stem the tide of magikin on the planet and also assists in studying the effect the Court's interference had on Nexuses, and magic in general.

The Magician's Folly, Book III
Tabia meets with Rebecca to plan a summer program between Heka-Aaru and Brakebills. In reality, it is a veiled excuse to send Anderson Thackery, Odette Caplan, and the rest of the group to Egypt in order to investigate strange occurrences that may be linked to a Nexus, though the group is not aware of this yet.

Tabia seems to have a knack for manipulation, convincing Arniston Carrow to allow the trip to happen in spite of his misgivings with Rebecca's behavior.
