Sugar Plums and Nutcrackers [Nutcracker AU]

[So a friend of mine on the Heropedia server is a huge fan of Turned Real specifically of Aurora and Stormer ship and made some AUs with them and one of them was a Barbie in The Nutcracker AU with Aurora as Clara and Stormer as the Nutcracker Prince Eric plus additional characters in roles and they wanted to see people make fics of their AUs so here we are!

Long ago there was a duo of siblings, a big brother and a little sister
Their parents had tragically passed when the girl was only seven, but with her brother around the pain was bearable
Until she was sixteen and her brother was tragically killed in a carriage accident
She was alone but not for long, for the Drosselmyers took her in and cared and loved for her as one of their own
While her heart still ached in grief for her family she had lost the Drosselmyers helped make the pain bearable as much as possible, to where even the eccentric Makuro worked well to try to create various items of wonders to help bring some joy for the girl
Then one Christmas Eve night Makuro gifts her a Nutcracker with white and pale blue coloring that changes her life-
During the night the Nutcracker comes to life as the missing and cursed Prince Preston, whose kingdom had been enchanted and taken over by the Rat King who wielded a staff of immense dark power and an army of fellow rats at his command
Aurora finds herself shrunken by the Rat King of a spell and now to reverse the curses and defeat the Rat King Aurora must help her Nutcracker find the Sugar Plum Fairy Princess whose the only person that can defeat the Rat King's power and set things right
But are the two able to find the Sugar Plum Fairy Princess to defeat the Rat King?
