I wanted to write about Natalya's history in Monarchy X Anarchy

Natalya Charnetskova is the only child of Czar Mikula Charnetskov but was diagnosed with Aplastic Anemia. The family doctor, Dr. Makari Rasputin, said that Natalya wouldn't live past sixteen years old.
When Natalya was eight years old, her mother, Julija Plevitskaya Charnetskova, decided to take advantage of her wealth and travel to exotic countries to escape the bitter cold winters and wet seasons of Perovskia. It's not uncommon for Julija to send souvenirs like stuffed pigs, jaguar hides, dinosaur eggs, and colorful birds back to Perovskia. Despite not having seen her mother for years, Natalya doesn't really miss her and hates the gifts.
Because of her royal seclusion, Natalya became odd. Even though she was a teenager, she still played with dolls and believed in fairytales. Natalya was also spoiled by her father and can be selfish at times. Natalya loves "ugly" colors such as black, grey, and plum. Her doll-like appearance is cute but she creeps other girls out especially since she saves spiders from being squished. Natalya partakes of ballet lessons at the Imperial Dance Academy, a school for privileged girls, but she has no friends except her acquaintance, Milena Pravdina.
Natalya adopted a penpal to fill the empty space of communication. Her penpal was Sir Alistair Glazastov, suggested by Count Aleksei (his father) to Mikula.
Natalya was born January sixth, Christmas Eve. On her sixteenth birthday, Mikula hosted a ball for her birthday in which Sir Alistair Glazastov and Sir Lachlan Armitage were invited. As a blessing from the kingdom of Chelicera, Lachlan was employed as Natalya's primary portrait artist and both men were assigned as her keepers.
Natalya falls in love with an old castle that her father plans on restoring as a dacha (seasonal home). After moving in Vogulka castle with only her knights, lady-maid, and about thirty servants, Natalya decides to help gain popularity among the people by hosting public events like parades, balls, banquets and festivals. At these events, she meets new people such as the pianist Ilarion Voroskilovski, purged soucoyant Elodie, a ruffian Nikifor Kodkhevich, the doll-crafter Zelig Grunewald, and mute apothecary Bernadine Ebersbach. Meeting with Bernadine introduces Natalya to the fabled Dark Artists.
Inside of bell tower behind Vogulka castle, Adrastus, once a fabled king, is sealed away. He steals Natalya's form and casts a spell on her turning her into a living doll. He escapes in search of seven singing towers to collect three stanzas of an evil ancient song. Natalya takes up the task of finding the stanzas and destroying them before the Imperial kingdom is threatened.
Because Natalya is not only an aristocrat but a member of the royal family as well, she attracts the attention of a pure soucoyant who lusts for Natalya's blue blood. Her blood is a vital key to destroying the ancient song so not only does the soucoyant want it but the Dark Artists need it to bring anarchy to the kingdom.
