Few children have the chance to grow up as fortunate as Addie.
Her family isn't perfect or anything like that. They're just normal. Her dad, Cadmus, is an ex-Quidditch player and now coaches all over the world. Her mum, Lia, is an apothecary who is specialized in healing potions. And their dog, Charlie, well... he's just a regular dog. There's also Jackson, but Addie knows not to bring him up too much because her mum gets too sad. She never got to meet her brother, since he passed away when he was born. But she still likes to count him as part of the family and she knows that her parents do too. Even though sometimes they fight and argue and don't get along, she figured they're as close to perfect as a family can get.
She grew up in London, spending her days at home or at daycare when her parents were working. When she got older, she attended a program for magical children, teaching them to read, write, and everything they'd need to know once they got to Hogwarts. She couldn't wait to attend the school where her parents had met. She just knew she'd be in Hufflepuff too.
But disaster struck just before she turned eleven. Her mum got a position in Australia, some fancy apothecary job in a hospital or whatever. Since her dad travelled all the time anyway, it only made sense that they move closer to her mum's job, dashing Addie's hopes of ever attending Hogwarts.
"It just doesn't make sense to send you so far," her mum claimed, as she told Addie all about the new school she'd be attending. Addie didn't care. But what was she supposed to do? It wasn't like eleven year olds could just leave home and do what they wanted. So she was grudgingly dropped off at her stupid, new Australian school and left to rot.
Nursing her anger and annoyance at her parents for ruining her Hogwarts dream, it probably wasn't surprising that Addie resisted everything about her new school, losing herself in her school work to avoid everything else. Never a particularly outgoing child anyway, it made it easy for Addie to not even make people's radars. She didn't go out for quidditch like her father wanted her to, she didn't join clubs or take up hobbies, she just hid in her dormitory and read books and did her homework, convinced that would show them.
But you can only do such things for so long before you find yourself getting bored and that was exactly what happened. She clearly wasn't going to be getting her way, and she was tired of making herself miserable. So she resolved to start making friends, meeting people, doing things. Anything that would mean she wouldn't spend another Saturday night with a book in her lap.
