Long ago, Luna and Celestia were both the rulers of Equestria, a land inhabited by ponies. Every morning, Celestia would raise the sun, and every evening, Luna would raise the moon. Together, they kept the balance perfectly. However, as time went on, Luna grew jealous: the ponies would be awake to enjoy the day and love, admire, and appreciate Celestia's work, but would always "shun" Luna's night by sleeping through it.

One day, Luna finally became fed up with Celestia's success. Not only did she refuse to lower the moon, but also challenged Celestia for the sole rulership of Equestria. At that moment, the bitterness in Luna's heart manifested and consumed her, transforming her into Nightmare Moon, a black mare of pure darkness. Celestia did not want to fight Nightmare Moon and begged her to lower the moon, but Nightmare Moon said her only royal duty was to destroy Celestia, and shot at her elder sister with magic beams, eventually knocking her down. Seeing no other way, Celestia reluctantly used the Elements of Harmony to overpower Nightmare Moon and banish her into the moon, creating the phenomenon known as "the Mare in the Moon" (a unicorn's face imprinted upon the surface of the moon).

Since then, Celestia took full responsibility of raising the sun and the moon, and a holiday was created to celebrate Celestia's victory over Nightmare Moon called the Summer Sun Celebration. However, Celestia only felt loneliness and regret for having to send her own sister away. In addition, it was prophesied that in a thousand years, on the longest day of that year, Nightmare Moon would be free of her imprisonment to seek her revenge.

Upon reading an ancient legend, Twilight Sparkle realized Nightmare Moon is about to return, however her mentor, Princess Celestia, encouraged her to make friends instead of worrying about the supposed "old pony's tale". Unfortunately, Twilight turned out to be right and Nightmare Moon was released during the Summer Sun Celebration, replacing Celestia who was supposed to attend it. Twilight and her soon-to-be friends chased Nightmare Moon into the forbidden Everfree Forest.

After conquering many obstacles left by Nightmare Moon in their path, they finally found the twisted mare herself along with the ancient Elements of Harmony, now reduced to inert stones. As Nightmare Moon whisked the Elements away, Twilight followed her into the portal and confronted her alone. She tried to use the Elements of Harmony as Celestia did, but for that, she had to find the "spark" that would make a sixth Element appear. However, no matter how hard she tried, she couldn't make the spark, and Nightmare Moon destroyed the Elements.

Fortunately, when Twilight heard her new pony friends calling for her, she felt a different spark in her heart; making her realize that the real Elements are not just some stones: they exist in the hearts of her friends. That spark triggered the final element: Magic (also known, of course, as Friendship), and reanimated the shattered Elements, converting them into jewels for the six friends to bear. Using the Elements of Harmony, Twilight activated a spell that struck Nightmare Moon, exorcising the darkness from her and transforming her back into Princess Luna. Unbeknownst to the ponies so deep within Princess Luna the evil that lived on as Nightmare Moon was shackled. Shackled deep in her subconscious.

Celestia arrived in the ruins where the battle took place, admitting that she knew of Nightmare Moon's return, but knew the only way to defeat her was for Twilight to understand the importance of friendship. Celestia walked over to a cowering Luna, who apologized in tears for her actions, and was granted forgiveness. Later at the celebration (held by Pinkie Pie), even the other ponies forgave Luna, gifting her with a flower necklace.

Yet.... With the removal of magic by Tirek.. and unknown to even Luna herself... Nightmare Moon emerged from Luna and gained a life all her own. Keeping to herself and watching...waiting...plotting. She still intends to take over all of Equestria for her own. Yet this time without being reigned in by Princess Luna. While at the same time keeping a tether to her once vessle ...Princess Luna.
