Professor Aesop Sharp is the assertive, no-nonsense Potions Master at Hogwarts School of Witchcraft and Wizardry. As a former Auror for the Ministry of Magic, he has become weary and jaded to the world and seeks to cure his chronic pain by having access to Hogwarts' library and resources. He has little patience for nonsense and time-wasting, and holds others to high standards while simultaneously expecting to be disappointed by them.
