Oh, Luna, why? Why does your life have to be so cruel to you? Why are the other ponies, even your sister, too blind to see how much you suffer?
Nightmare Moon... I'm sorry. I'm really sorry it had to come to this. I'm sorry you had to use force to get your message across... I'm so sorry the only thing you've got for that is your banishment.
I wish... I wish I was there to change everything for the better myself...
Ok, so I have to mention that this story is inspired by many things, but mostly by these fanfictions:
My Little Luna
My Little Villains
