Lady Galvin was Sophie's Level Two alchemy mentor. Lady Galvin is impatient and disagreeable, because she thinks her talents are being wasted, and she should have much more important work. She is said to have the highest failure rate of any mentor because she hates her job. It is said that Lady Galvin hates her job, and is only Mentoring because of the title. In Book 1: Keeper of the Lost Cities, Marella says that she (Lady Galvin) failed the prodigy she taught prior to Sophie on purpose. She is known for highly valuing her cape and is extremely irritated when Sophie destroys it when she whips her serum instead of performing WHAP (Wash Hands And Present). When Lady Galvin makes the prodigies iron her capes in detention, she does not let Sophie anywhere near them. Though she seems to regret it, at Sophie's final tribunal in Book 1: Keeper of the Lost Cities, she says that she will not pass Sophie in alchemy. Lady Galvin knows that this might result in Sophie being expelled.
Lady Galvin is described as slender, with red-brown hair typically in a tight up-do with twists. Her prized cape is hunter green, made of a silky fabric with elaborate pattens with emeralds.
