I'm going to kill you, darling. (prologue.)

The story is set in the sixth year of Hogwarts schooling, and someone new comes to the school. Emmeline Mallory (portrayed by Olivia Wilde) is a Metamorphagus, which she uses to her full advantage, and has a hidden past, some of which she reveals to Draco Malfoy (Tom Felton).
Emmeline is the only new character so far introduced to the story, though more are to weaved in at a later chapter.
