Talia was an anesthesiologist for a local hospital and Hadrian owned a chain of businesses, ranking them as one of the few wealthiest families in Athens alongside the Sakellarios family, who were very close friends. Talia, Hadrian, Thesus, and Alejandra had grown up as friends and even went to school together. Unfortunately, Talia was born a Squib and was looked down upon by many. Despite this rare occurrence, the Sakellarios family never turned their backs on Hadrian and Talia, gaining their utmost respect and friendship throughout the years. Aikaterine was basically raised among the nine children by the four adults, who helped each other in raising the lot of them. However, Aikaterine was more drawn to Malia Sakellarios than any of her siblings. Despite her being younger, the pair bonded quickly and became very close friends and acted more like sisters than anything.
Being born into a prestigious family had it's perks, of course; aiding immensely when it came to muggle school. She rose through the ranks to become one of the popular girls in her year. People nearly worshiped her. However, the attention made her rather uncomfortable as she was a modest girl. She did not prefer to be known as the rich and popular girl. She wanted to be recognized as intelligent and powerful. She wanted people to understand her love for classical music and her interest in poetry rather than how she did her hair, what makeup she was wearing and if her fall collection was as amazing as the rumors stated. They never understood her. The only time she ever truly felt understood was when she started her first year at Hogwarts.
Her parents were very proud of her progress in school that they rewarded her with quidditch lessons, as her father was a former professional quidditch player in Greece when he was younger and before he was a father. He showed her all of his moves. He tried her in each of the positions but she excelled best at being a seeker, just like he had when he was her age. He spent thousands of dollars on practices and a personal tutor (some of his friends who still played on the teams) and it wasn't long before she was kicking some major butt in quidditch.
It was hard without Malia being in school with her but she learned to cope and was thrilled when Malia finally joined her again. The difference this time was that Malia was sorted into Gryffindor while she was a Slytherin.
Despite this gap, Malia was her support system, someone to confide in with her deepest and darkest secrets. This worked both ways - as Malia had opened up to her about being bisexual after she found herself interested in Valentina. Mal was her shoulder to cry on when a boy broke her heart for the first time, when her favorite pet died, and most importantly when her parents passed away. That was the biggest impact in her life. Dark Wizards murdered them in cold blood for not offering them information that they wanted. This changed her attitude from reserved and observant to constantly angry and closed off.
Upon the investigation, it was concluded that Aikaterine was to stay with the Sakellarios family as they were the closest people to her parents. They gladly took her in. Not long after, Kat's inheritance came in and helped immensely when it came to raising her, buying her supplies for school and money that could be set aside for her future after graduation. However, graduated never came. In fact, Aikaterine fell ill with a wizarding sickness that nearly claimed her life before her eventually fall into depression and suicide.
The truth came out when Aikaterine was twenty and discovered by the French Ministry of Magic to have been a captive of Lachlan Metaxas, the same dark wizard that got away with the murder of her parents. This was his humane attempt to tie up loose ends, fearing the child had seen and remembered information pertaining to that fateful night. He faked the girl's suicide in order to conclude her disappearance and held her in the basement of his home in France for nearly three years until she was discovered after allegations of domestic violence by neighbors brought the police to unsuspecting Lachlan who was arguing loudly with her in the kitchen. When it was discovered by the French Ministry that the man in question was indeed a wizard, they took on the case and found more than they bargained for; a teenage witch who was legally deceased.
Aikaterine was released and remained in France for nearly two months until she chose to finally migrate back to London and attempt to reconnect with her family and friends and those who still believe that she is dead. With the left over money in her inheritance funds from before she went missing, she plans to purchase a building and open a business but is unsure of what.
