Backstory:

Before Birth:
Ji-soo was born the only child to Agnes Desjardins and Ha-joon Im in Namwon-si, Korean. Her father Ha-joon was the only son to the Im family, a reputable pureblooded house. The family was strict and controlling, often dictating the choices of his life for him. This caused Ha-Joon to become rebellious and out spoken, not helped by the fact that he attended Hogwarts. This was due to his first instance of magic occurring in England when on vacation. There he met the Desjardins heiress, Agnes, whom dearly too did not wish to return home.

Agnes Desjardins was born to an English father, one Idris Beddoe a spare of the Beddoe Family and Elodie Desjardins the only child of the Desjardins Family. Both families, while small still, were known for their reputable blood. Although the Desjardins in recent years had been known for their oddities, for they had interests in muggle culture. Later they would be deemed blood traitors, disliked for how they scoffed at pure blood culture. In the end some members of the family even married muggles, causing quite the scandal.

So when Idris wished for their family’s reputation to rise back up he offered his daughter’s hand in marriage. Anges was angered by this, so she went to her best friend at the time, Ha-Joon. Ha-Joon was also experiencing some problems with his family, for they had a marriage arranged for when he returned to Korea. So they devised a plan, they’d elope together, so that they may enjoy their own chosen partners without the families interfering. After all they had both married families of good blood hadn’t they?

So upon returning from their vacation loosely disguised as a honeymoon, they returned to Korea. The Im Matriarch was furious at her son’s actions and spouse, so she pressured the couple for a child. Hoping for a son she could influence to later “guide” the family in the “right direction". And so caving to the pressure the couple welcomed Ji-Soo into the world in May of 2014.

After Birth:

However, everything was not well. The Im matriarch was furious at the fact that they had bore a daughter and not a son. Agnes and Ha-Joon, fearing for their child’s welfare and happiness growing up, decided that it would be better raising Ji-Soo in France with her maternal family. So at barely 6 months old Ji-Soo was renamed to Atreus and moved to Ault, Somme in France.

It was agreed that Agnes would be the main parent to raise Atreus, as then Ha-Joon could stay in Korea to appease his mother so that she would not bother their child. And so Atreus was raised for the first 5 years of her life in Ault, among the rocky beaches and chalk cliffs of the coast. Because of Ault’s location on the coast of the English Channel it was very easy for the two to visit the Beddoes. And they often did, going to socialite events and parties to meet up.

During these parties Atreus would often find a quiet spot to sit and read or observe quietly, as they were a shy child. It was here that they met one Cassius Hirano. While the two did not become thick as thieves immediately, they did enjoy each other’s company.

When Atreus was 5 years old, Anges’ cousin Leon Beddoe passed away rather abruptly. His wife, Arrianna Beddoe Nee Lestran, had already passed away in an accident so there was no one to inherit his estate. This left both the Beddoes and Desjardins puzzled over what to do with his house and muggle business. As his muggle wife had started a fashion business and after her death he kept it. The house too was not desirable as it was in a neighbourhood in Muggle London.

However Agnes saw an opportunity, as Atreus had been slowly gaining a fear of the ocean. Agnes had always cautioned them so they would not be swept away by the tide, but it slowly got out of hand. As Atreus was beginning to have night terrors about the ocean. So Agnes took the chance to move Atreus to somewhere inland. It was a good thing they did as a large storm later had damaged the house, flooding parts of it with sea water. It would have only fueled Atreus’ nightmares.

So Atreus moved to Wimbledon, London shortly after cousin Leon’s death. Agnes decided to keep the fashion brand much to the surprise of the entire family as it was a muggle business, but she saw it as a way to escape the high society world if it all became too much for the small family. Ha-Joon through the years had continued to visit Agnes and Atreus, and agreed with the move to make Atreus more comfortable.

Later at age 8 Atreus had their first incidence of magic, it was sadly not a happy one. While on a walk in muggle london with her nanny, Atreus came across a large dog. The dog was aggressive and able to slip the leash it had been on, much to the despair of the owner. It bolted after Atreus scaring her into running where she was chased through streets of london, until she was cornered in an alleyway. In an act of pure fear, her magic responded flooding the alley with fog, allowing her to slip away. After this she wandered the streets of London for 3 hours until the police found her and returned her to her mother.

Since then Atreus has a phobia of large dogs, and has become even more soft spoken. Though she gained the fear of large dogs, her fear of the ocean has lessened with the time away from the coast. Though large bodies of water still make her feel nervous.

Personality:

Atreus was always shy and introverted, she’d rather cling to her mother’s skirts than play with others her age. Bookish and quiet she fades into the background, never wishing to be the center of attention. Often Atreus hesitates when making decisions, they often get paralyzed when offered too many choices. Full of anxiety but still can hide it pretty well, according to other family members. Her mother and father often call her mask her “brave face”, which she likes. She always tries to represent her family with grace and tolerance, hoping to make her parents proud.

Appearance:

Atreus is a little tall for her age, this often means she's thin and lanky no matter how much she eats. Her father says it's just her high metabolism and that she’ll grow out of it, she certainly hopes she will. While pale in the winter, Atreus tans easily without burning in the winter much to the envy of her mother. With her thick black hair the heat can still get to her, Atreus’ hair in the summer must be always off her neck lest she loses her mind. With a button nose and brown almond shaped eyes her family often praises how cute she is, much to her embarrassment.
