Five Score Divided by Four? Where have I heard that before? Psh, sounds like some cheesy title to a fanfic. What is this itching?! Wait, since when have I had Luna's cutie mark on my thigh?
Twilight recieves rather late invitation from Princess Celestia for the first "Winter Solstice" celebration for Princess Luna. And while staying there, something is going to change her life...
Twilight wakes up in a hospital near the border of Changeling country, but something about her is...off. She remembers nothing of her adult life, and she seems to be juggling a bit of an alter ego. An evil alter ego.
A centuries-old law comes into play one day mandating that Celestia take a vacation from her duties. Meanwhile, various ponies begin experiencing romantic frustration as Hearts and Hooves Day draws near
Twilight loves to learn. When she asks to study abroad, Luna is quite happy to send her to a place full of new information and a rich history that is irreversibly entwined with Equestria's: the moon.
