Twilight Sparkle from a very young age proved to have a great ability for magic, one worthy of being part of Princess Celestia's school for gifted unicorns, however, just when it looked like Twilight would pass the entrance exam with an outstanding demonstration of power, the dragon egg she was to hatch only fell to the ground, fractured with a small crack, but not cracked open.
The unicorn won her cutie mark that day but was rejected to enter what would have become her bright future. Now, as an adult, Twilight works in the Canterlot library, almost isolated and full of remorse against herself.
One day like any other in her routine of monotony and self-loathing, one of Celestia's most talented students, Sunset Shimmer, bursts into the library, in an attempt to escape for a moment from her burdensome labors as a disciple, she meets Twilight and the two embark on a relationship that will question the purpose that life has placed on both of their shoulders, the place they truly seek to play and the love they have for themselves and for each other.
