Dr. Odatra Orulin Ornan

Dr. Ornan is a wizened gnome that's nearly blind from age. Still, her mathematical mind is unmatched in Khorvaire, having published the majority of the major mathematical breakthroughs of the past two centuries. Her department of arcane science and theory eschews the practicalities of spellcasting, focusing on topics such as the planes and magical phenomena.
She has resigned herself to teaching for the rest of her days, but does so in a perfunctory manner. She is neither anyone's favorite or least favority professor. Unbeknownst to her, the administration is already looking for her replacement when she dies. There is also talk of naming a minor eldritch machine used to detect and measure arcane power after her posthumously, but that has not been confirmed.
