Mouse King x OC (Nutcracker Fanfiction)

(Cover image not mine, belongs to Katogi Mari. I'm a HUGE fan of the Nutcracker since childhood and would like to write my own version someday. For now, I want to write this fanfic because I'm not the only one who wants this.)

Long before Clara Stahlbaum was born, Drosselmeyer had another goddaughter from the Silberhaus family. One eerie night, when she was very little she heard the chanting of mice. That was many Christmases ago and has completely forgotten about it. Now a beautiful young lady of age 17, who pitifully grew ill and weak in her legs. How she envies her female cousins, who dance elegantly every year at their Christmas party. She yearns for a suitor who will carefully guide her weak body. This year, however, the Mouse King has his sights on her . . .

A tale that resembles the classic yet with an alluring, dark twist.

(This isn't for a specific version of any "The Nutcracker" just something in general if that makes sense.)
