Originally she was born in Skagen, Denmark, to a Danish father and German mother. Neither parent was aware of the magical community, so it was quite the shock when she started showing signs. When she turned ten the family moved to the city of Bognor Regis, England for her mothers new job.
Though she missed her friends and home, it didn't take long for her to adapt. Though learning English was a bit of a struggle she just about coped (though to this day she still makes a few mistakes). She would constantly attempt to impress people with her growing magic skills, however it always backfired and just made the kids scared of her. So of course she eventually stopped and started to ask what on earth was going on.
Her parents, whilst supportive, couldn't help her much. They simply told her not to go anything - no matter if she could control it or not - and to go about as if everything was normal. When she turned eleven she was finally given the answer by a teacher at Hogwarts, who explained that she was a muggle-born witch. The teacher assisted her in buying all her supplies and when she was finally ready, she gladly left to attend her new school.
She was in her third year at Hogwarts when she came out to her family as a transgender girl, expressing her desire to transition. Though confused and shocked, she was supported in her name change and gaining clothes that made her more comfortable. Passing was not particularly hard for her, though gaining the right to be called her true name by students and staff and for her pronouns to be respected was difficult. She's very happy with where she is currently.
