Ursula V. Nessa is the Head of the Alchemy Department at Disney High.
After moving from the city of Atlanta, Ursula took her passion for Alchemy elsewhere, and after fully realising her potential, she moved on to teaching the students at Disney High, as they were among the few with the highest prospects for their future.
Upon her application, she instantly became the head of the department and, while being disliked by most of the students, was a good teacher, and most of those she taught passed their examinations.
During an inter-school tournament, she met Evelyn Quinn, and the two became fast friends, and exchanged teaching styles and their knowledge. She even inspired Quinn to start Alchemy.
