A small filly, a terrible fate, bat wings, a sickness without a cure, a library, and how to deal with the only thing good that has ever happened in your life disappear.
Twilight Sparkle tries to help the filly that shows up on her door step. That filly has a sickness. She coughs up blood every once in a while. Her bat wings are questionable and for some reason, will never tell Twilight about her past. Mostly because she can't remember. Twilight raises her and when she just starts magic school, the whole world falls around Twilight. That little filly, was the best thing to happen to her.
