Introducing...Nora Avery version 3.0: Bitchier, Egomaniacal-er, and with Seamless Organization of All Your Media Files. Okay, not the last one.
Nora is a sixth-year Ravenclaw and The Elitist, so she thinks she's better than just about everyone else, particularly when it comes to intellect and wit. She idolizes her brother Oliver - even when she's cheeky with him, it comes from a place of affection.
There are two sides to Nora, and whether your characters like her will depend on if they've caught on to what a terrible human being she actually is. But as they say, the great failing of genius is that it needs an audience. Nora is pretty charming, and she "puts up with" most people so that she has them around to notice just how clever she is!
This year, she's going through something very, very inwarldy trying: her attraction to a Mister Jack Macmillan. She hasn't shared it yet, because she's utterly, utterly appalled, and is hoping like mad that it will just go away. Unfortunately for her, it won't anytime soon.
So! She needs an audience friends friends friends, enemies, anyone who has asked her out in the past and been sweetly but embarrassingly turned down...and anything else you can think of!
