Within the heart of the Everfree Forest lies a solemn cave that houses a mare from a time none can truly discern. Guided by her guardians, she awakens and ventures outside the world, entering a realm that she doesn't fully recognize and must somehow integrate herself into society with the aid of a friend called Fluttershy.
It shouldn't be too difficult if only the mare could speak lucidly and say a sentence. In time, she will learn.
