So this is Alecto Carrow. She's 19, a pureblood from a lower class family, a former Ravenclaw, and currently works for The Office Against the Illegal Trade of Magical Creatures. Don't want to tl;dr you, so you can read more about her here!
So, friends intellectual peers/acquaintances, annoyances, Ministry co-workers, future fellow Knights, maybe family?? Throw them at me!
