Hermione sighed, running a hand through her hair.  "My Ilvermorny letter was delivered by the school’s Headmistress and President Symons.  There was a rather lengthy discussion given my unprecedented situation since Dad had announced his run for President just a few months before my eleventh birthday.  All to say, I was taught a series of tactics to mask who I was - a certain degree of occlumency, a spell to mask my accent, and a backstory so well conceived that no one would think twice.  I used occlumency to create false memories of myself for myself, a shield so-to-speak in case anyone tried to get in my head.  Obliviating my parents was one of those memories.  You needed to believe it and I needed to have my fake memory of proof.  Fortunately it was unnecessary."
