In the shadow of the Sun Empress Celestia, the dreamy orphan Twilight discovers her terrifying heritage and dark secrets that could threaten the fate of the world.
A thousand years ago, Princess Celestia banished her sister to the moon, that much we know. What wasn’t known, and what Celestia kept secret was that before her banishment, Luna had given birth to a foal; Twilight Andromeda Sparkle.
Twilight Sparkle is the daughter of Luna. When Luna is banished to the moon by her own sister, Twilight feels hatred of Celestia for having banished her mother to the moon.
Twilight and her mother, Luna, return from the moon a year early. Things are great for the mother and daughter duo... at first, but something amiss. What could it be?
