Freya Bast is the professor of Transfiguration at the Hogwarts School of Witchcraft and Wizardry. A former Auror who worked under Harry Potter, she suffers from a transfigurational disorder caused by a previously unknown transfiguration curse. While investigating a pet shop in Knockturn Alley, Freya was attacked by the owner, who, it was discovered, had been transfiguring Muggles into animals which she then sold as pets to witches and wizards. The transfiguration curse is slowly transforming Freya into a cat.
