Katerina Romanov was sitting in her seat for her History of Magic Class. Sitting up rather straight, despite being rather bored, she tried to pay attention. This was proving to be an extremely difficult feat, however, for Professor Binns was the most monotonous teacher at Hogwarts School of Whichcraft and Wizardry on top of being a ghost. Her mind couldn't help but wander.
As she was sitting there, her mind couldn't help but wander to her family and her history. She could think of her great grandfather, in text and description only. Her great grandfather had been the last Tzar of Russia, named Nicholas II. A Tzar is something like an extremely powerful king. Her grandfather often told her how his father, the Tzar, had been a horrible ruler but a wonderful father. He had been so determined to keep his family together, despite hiding his magical abnormality, even at the time of their assassination.
Yes, Aleskey, the next in line to the throne of Russia, had been killed with Nicholas, Katerina's great grandfather. But what most people, including the Bolsheviks, the ones who killed her family, hadn't known was that, four years after Aleskey's birth, so 1905, her grandfather, Ivan, had been born. In 1916, his father sent him off to Hogwarts, despite it being simply called Boarding School to the few that knew about him, in England. In 1917, just after Ivan returned to school after the holidays, the Romanov family was taken from the Winter Palace into house arrest in exile. The next year, while he was on the way to the palace for a visit to his family, the Royal Family, the ones the Bolsheviks knew about, had all been killed.
Katerina could remember her grandfather telling her of how, as soon as he returned to the palace, he wrote the Headmaster at the time to come and help him protect his family's things. The Headmaster came the same day and helped him make a replica palace and then hide the real Palace. They transferred all of the Romanov Fortune into Gringott's St. Petersberg branch. To this day, this branch had never had a successful robbery.
In 1923, Ivan had graduated from Hogwarts and got a job as part of Paris' Ministry of Magic. Six years later, in 1929, he got married to a woman by the name of Isabella. Four years later, in 1933, they had a son named Nicholas, named after Ivan's father.
It was 1952 when Katerina's father, Nicholas, and her mother, Alexandria, a Russian woman working in London at an apothecary in Diagon Alley that was going out of business, moved back to Russia and announced that there was living descendants of the Royal Family that had been executed. Ivan came with them after the death of his wife. They were immediately accepted within the high class, basically getting their position as Royalty without the title or palace again.
In 1956, Katerina was born, and she quickly became one of the most popular underage person in Russia... mostly because who she was related to.
The year is 1973, and Katerina is seventeen. Her father was acting as a sort of Ambassador for the Russian Ministry in London, England, and transferred her to Hogwarts. It looked better to have graduated from Hogwarts than the small magic school that she had gone to before. For, although she did not know this, her father was working on getting the Romanovs in power again. The Russian citizens were getting tired of the current government. People have seen how productive her father was in the ways of policies and volunteering. It would only take a little bit of convincing for a new revolution to occur and, if they succeeded, the Romanovs would have everything back, including the real Winter Palace. The enchantment that had been placed on it required a true descendant of Tzar Nicholas II, in power, to come and release it. At the same time, it would make the replica disappear.
