Estelle Allen is a slim, pale-skinned Scottish girl with soft freckles scattered across the bridge of her nose and cheeks. She has long dark brown hair that naturally falls into loose waves, often escaping whatever braid or ribbon she tries to tame it with. Her eyes are a shining brown. She tends to favor practical clothes but, she still keeps the necklace her grandmother gave her when her powers first appeared. .

Estelle is a very cheerful and playful child; she loves teasing others and drawing. However, she is very clumsy and unfortunately, she has the bad habit of speaking before she thinks. She's the pride of the family because she learned to read very early on and have her powers before most of her cousins.

Estelle was born into a old wizarding family. And she grew up in a small coastal village in the Scottish Highlands. Her father works as a magical cartographer for the Ministry, mapping shifting magical landscapes and ley lines, while her mother is an apothecary witch who crafts remedies and potions for magical clients.As an only child, Estelle spent most of her time playing outside, drawing magical (and not so magical) plants, and helping her mother welcome her customers. She was often with the muggles children of her village but had few close wizards friends her age, aside from occasional visits from her family or her parent’s friends family because her parents and her was the only wizarding family of her village.Thanks to her family, who belong to the old aristocracy (although not very traditional), Estelle speaks French fluently (this was common in old families and is considered a ‘noble’ language).

Estelle discovered her magic when she was 4 years old while playing with her cousins climbing cliffs: when she fell, her magic activated and created a bed of seaweed so she could land without getting hurt.She was the first in her family to have them so early and her grandma was so happy that she gave her a necklace wich give her access to her grandmother's castle library.
