One thousand years ago, Princess Luna fell to her corruption. Driven to madness by loneliness, shunned by the very subjects she strived to protect, and by jealousy of her ever-brighter sister.

In her desire to be seen by her subjects, Nightmare Moon brought about an eternal night, that they might finally view her as equal to the beloved Princess of the Sun.

Princess Celestia was forced to confront her, and they fought. Nightmare Moon was outmatched, and banished.

Five hundred years ago, Princess Celestia fell to her own corruption, born of grief at the loss of her sister, and rage at her own immortality as she watched those she cared about crumble to dust, while she remained, unchanging.

Two hundred and fifty years ago, the last free country on Equus fell to the newest and only empire on the planet:

The Solar Imperium, ruled with an iron hoof by Queen Daybreaker, Goddess of the Sun.

Today, Princess Luna returned from the moon.
