Mental Description:

Reducio

She has a rather quiet and awkward personality, but if she's comfortable around someone then she tends to be quite blunt and sarcastic. She prefers reading books more than interacting with others most of the time and rather dislikes having to work with large groups, preferring to work with 2 or 3 other people at most. She has a particular fondness for all types of animals or magical creatures, muggle or magical (her parents allowed her to read books on the more mundane species, so she knows a lot about them even if she's never seen many in real life). She's rather ignorant of the ongoings of the greater wizarding world and politics involved, due to her isolated upbringing. She has hyperthymesia, so she remembers everything she has experienced, good or bad.

Biography:

Reducio

She grew up raised to be a pureblood heiress, having tutors in etiquette, dance and piano since she was 4 years old. Her parents are rather protective of her as her mother had gone through a few miscarriages before she was born, so she grew up a little isolated from the outside world, resulting in her rather awkward personality around others that she doesn't know very well. She grew up with a lot of love from her parents, but she does not have any friends prior to coming to Hogwarts. She spends most of her days either studying, reading or interacting with the various creatures kept at her estate.

Her mother is a pureblood, coming from the Noble House of Hembley from England. She has straight, shoulder length dark brown hair and icy-blue eyes. She is rather tall and is an ex-magizoologist who now works as a housewife, taking care of River and their various creatures along with the aid of their house elves, who are treated quite well thank you very much.

Her father is the Lord to the Noble and Ancient House of Luxley, a pureblood family hailing from Norse origins who settled into England in the late 18th century. He has slightly curly jet-black hair and grey eyes, is about 6'1 and fairly muscular as he works as an auror for the Ministry of Magic.

First Instance of Magic:

Reducio

Her first instance of magic was when she was 19 months old, according to her parents, and she summoned one of her toys to herself that had been on the other side of the room. She also turned her father's hair green when he annoyed her by taking away one of her books when she was 3. she has had a couple other instances of accidental magic since then, but none are of much note.
