Sieglinde Losnedahl was born in Steinkjer, Norway, to the German Gabriele, and her husband the Norwegian Ole Losnedahl on the 7th February. She was an only child, and expected to attend Durmstrang like her parents and friends, or even Hogwarts, as some Norwegian wizarding kids she knew did. Instead, she was invited to EESM and Durmstrang, much to everyone's surprise, and to her parents' horror, she chose the smaller school, EESM. She was almost sorted into Kask, but instead became Boyanova, fitting with her loud personality. In her fifth year she was given Prefect position, and will be a prefect until she either loses it, leaves school, or becomes Head Girl (She seriously hopes for the latest, but isn't particularly bothered otherwise). In her fourth year, she and her Nikelkaj probably-best friend Ecaterina Kogălniceanu began doing annual tours of the school for first years and transfers.
Sieglinde has white-blonde hair which she often dip-dyes blue or pink. Her eyes are blue and she has pale skin, and her model is Perrie Edwards from Little Mix.
