Potionsmistress of Hogwarts: The After Story
Annipe is usually quite contained and ladylike, but that ends when she starts talking. Upon hearing her own voice, she starts to lose herself in her own thoughts, and can become highly passionate if necessary, she loves to joke around with her students, and seems quite unlikely to be part of Slytherin.
But that's exactly how she is so cruel. She is very cunning, and knows that it is always best to have a different face for everyone you meet, and if they don't know the difference... all the better.
A sycamore wand of 13 and a half inches, it was actually made in Egypt, so it has a core of an astoundingly rare African unicorn. Her mother was endlessly proud to hear of it.
Annipe is actually the daughter of the old Care of Magical Creatures teacher Silvanus Kettleburn who was replaced by Hagrid. He married a Gypsy girl, and had Annipe, who went to Hogwarts and became an adept Slytherin girl. She was astounding at herbology, potions, and food related magics, and worked for the ministry identifying poisons and developing new potions and techniques.
When He-who-must-not-be-named rose to power again, she fled the country, hiding in Cairo with her mother, but she has returned upon the headmaster's request to teach potions.
She is starting an "Alchemical Club" for the most talented of charmers and potion-makers. She feels it is a good subject to be taught, and she herself often fantasizes about the philosophers stone and other such alchemical works.
