This fic is excellent! I adored the mentorship between Will and Millicent. Both characters standout so much... I liked the mention that Will was a Slytherin. Not sure if I've seen her mentioned that way, but it's good and it fits. Millicent... I've always thought she would have trouble settling in, and you've written that perfectly here. So much to love about this fic, it deserves all the comments!
