Plot summary
Celestia and Luna are born to a herd of earth ponies, not dissimilar from regular earth ponies. They are born as earth ponies, and not alicorns, but their colourful manes and coats stand in great contrast to the earthier appearances of the rest of their herd.

The two princesses-to-be spend their foalhood with the herd, until they both grow horns as young mares and must leave their parents and their herd to join the mysterious unicorns deep in the Everfree forest.

During their time among the unicorns, Luna and Celestia learn to use their newfound magic, and come into direct conflict with the unicorns' strict culture and rule system. Eventually things come to a head and the two ponies try to leave the unicorns, but are prevented from doing so and placed in captivity.

They eventually escape the unicorns and head out into the depths of the Everfree forest alone, in search of pegasi to teach Luna how to use her newly-sprouted wings.
