During the reign of William III & Mary II in 1692 the International Statute of Wizarding Secrecy was signed, separating the lives of the magical and the muggles. The reign of the muggle royal family over the magical population of Britain - and later the United Kindgom - was largely undisturbed; both British societies observed the same monarch until the pure-blooded of the magical society began demanding detachment. From what started as being general discontent grew into violent actions with a magical civil war approaching over the horizon. In a stroke of luck that avoided turmoil, the ruling King George III had a magical daughter hidden from the muggle society. This daughter, Princess Charlotte, was quickly installed as the monarch of the magical society of Britain - an act which finally separated the two.
The arrangement worked out perfectly for both societies; whilst both monarchies were separate, the two worked closely to ensure similar values were shared and upheld. When the muggle monarchy changed their house name to Windsor, the magical monarchy followed suit. Everything was harmonious until the ascension of King Henry II. A monarch who wanted to devolve the power of the Ministry itself, Henry became tyrannous early on in his reign. Turmoil that threatened to overthrow the monarchy rose again, saved only by the forced abdication of Henry and the replacement by his eldest daughter, Victoria.
Proving to be the saving grace of House Windsor, Queen Victoria remedied her father's mistakes. She appealed to all crowds of magical life; advocating for no discrimination for species, being proud enough of her pure-blooded heritage to satisfy those who cared whilst remaining completely relatable for all. Her reign, still going strong, has remained among the most harmonious and popular since the magical monarchy's establishment.
Being the second born daughter of Queen Victoria and Prince Louis, Princess Mary stood out among her six siblings for her passions toward muggle society. She met her prince charming, a muggle boy named Colin in primary school and forged a love for the man over her years of education. Twenty whole years after their first encounter, Princess Mary married Prince Cornelius - whom changed his name to become befitting of his new status. They had their first child, Prince Archibald three years before their second child, Princess Eleanore entered the world. Both adapted well to the royal lifestyle and the little family remained undisrupted for nearly four years until Mary's third and final child was born. Princess Thyra Roselind Grace Cosima of Windsor, nineth in life to the throne was a role-model infant with the blessing of sleeping through the entire night and hardly ever crying.
But the period of peace became interrupted when she was four years old and begun to exhibit behavior issues with signs of depression - surprisingly enough for the young child. She grew an intolerance for anything to do with lessons and royal duties. By the age of five, her magic had showed for the very first time when she froze the entire fountain outside. With no other options than to try her in a less stressful lifestyle, Princess Mary allowed Thyra to stay with Cornelius' muggle brother. Things were perfect for two years and Thyra flourished in the countryside with a farm to keep her busy. Once she hit her seventh birthday, her uncle took her into town to sell vegtables she grew at the market and turned his back long enough for a man who recognized her identity to kidnap her from their market table.
He first tried to hold her ransom, instructing Cornelius's brother to contact the royal family and give them his demand of a million dollars or he would kill the little princess. When her muggle uncle shot through the bluff and refused to do as he wished, the man fled with Princess Thyra to another country and dropped her off in the slums of Italy to fend for herself. For nearly six years, her uncle continued to pretend that Thyra was still on the farm despite his fear of them finding out he lost their child. But when Princess Mary grew suspicious, she sent Prince Cornelius to visit Thyra and discovered she was missing. Backed up with no room to lie, his beother confessed to the kidnapping. Once the royals learned of this news, they enlisted all the help they could to locate the princess. She was discovered just a month shy of her fourteen birthday and was taken directly back to Linlithgow palace.
Princess Thyra was severely underweight and timid after her years spent on the streets and struggled to adjust to her real family and all the lessons and work that came with being nineth in line to the throne. The langauge classes weren't so bad but the addition of missing her first three years of wizarding school, was forced to do it all in one year so she could continue on time with her fourth year. Thyra worked extremely hard to catch up and often burnt herself out to the point where she could be located at any area of the palace, sleeping peacefully despite the traffic. While life as a royal is sort of fun, Thyra struggles with being proper and usually passes out during etiquette class from boredom. She refused to attend Hogwarts until her seventh and final year, ultimately being sorted into House Gryffindor.
