Sixth Year: Mysteries abound as sixth-year begins. Before Marlene McKinnon died, she left a series of notes that may hold the key to stopping Voldemort. Unfortunately for the Order, the notes are written in a cryptic alphabet that no one, not even Dumbledore, can translate. Meanwhile, there's a charismatic new DA teacher, a transfer student from Beauxbatons, and snogs galore. Draco struggles with familial responsibilities, and everyone else just tries to get through one more year.

This is a background story of Bellatrix's Death-Eater initiation ceremony. It basically chronicles why Bellatrix turned out to the way she did and the various things she did in order to accomplish her goals.
