She's Analisa's twin sister, a Gryffindor, and seventeen. She comes from just days after her brother's attack and death at the hands of Fenrir Grayback so she's trying to make sense of that. Waking up in a strange place isn't going to help much with that. Canon wise she comes from a time when things weren't too bad, Dumbledore is alive (she just seen him a couple days ago!) and really before her brother's death she wasn't overly involved in the war.
Typically she's a pretty outgoing personality that embodies the Gryff bravery in the sense she wants to try EVERYTHING, at least once. It was this desire that lead her to want to be a curse-breaker so she could do something new, dangerous, and see the world. She was even going to do an internship after her graduation from Hogwarts which was coming up. Since her brother's death she's feeling a bit muted but she'll bounce back quickly. In the village she's the Dream Interpreter! She's excited about that! People's dreams are interesting and she wants to open her own shop and just work at doing that. Of course she's living with her sister too.
Yep. That's about it. You can read more about her Here if you like. Now she needs plots and love^^
