What happens on Maidens Day is a closely guarded secret among pegasi and earth ponies. A celebration of culture, magic, and their parts in the natural order of Equestria.

Unicorns haven't taken part for more than a thousand years, but now that Twilight is an alicorn, she's finally allowed to see what happens there. And when two of her friends are chosen to take part in the ritual at the center of the festival, there will be more than one lesson about the magic of Maidens Day.
