Author's Note:Before the story starts, I would like to say a few things: Firstly, I do not own My Little Pony. Second, I know that any diligent brony will call me out on a seemingly obvious error. It is not an error. Continue reading, it will most likely be cleared up. Finally, this is my first story. I'm not asking you to go easy on me. Just keep in mind that I am learning. Read and review, if you would.

2000 years ago, there were three powerful unicorns who served the great king, Discord. These 3 unicorns were the best of friends and known all across Equestria. They discovered the most powerful artifacts in the universe, The Elements of Harmony and eventually, through their dedication to their very important jobs, became alicorns. Luna, the youngest of the three, was tasked with the job of raising the sun every morning and lowering it every night. Her elder sister, Celestia, had the job of raising the moon at night and lowering it during the day. Finally was Starswirl, who was tasked with summoning the stars every night and making them disappear every morning.

Starswirl had the most difficult job. He was responsible for the appearance of over a million stars every day. Even with his Element of Harmony and his natural-born talent, he struggled. So one night, while experimenting with some magic of his, he discovered a new, even more powerful magic than what he was using. But there was a catch to this power. It slowly drove him mad, filling his head with evil thoughts until, one day, he concocted a devious scheme.

His plan was to create a spell that would allow him to steal the power from his friends. With power over the sun, moon and stars he hoped to overthrow Discord and rule Equestria with an iron-hoof. He set out to write such a spell. When he thought it was perfect, he snuck into the training room where Discord was practicing magic with Luna and Celestia. Undetected, Starswirl fired the spell. Luna and Celestia, completely by chance, avoided the spell. The spell did indeed hit something though; Discord. Almost instantly the spell takes effect, turning their once loving and peaceful king into a deity of violence, chaos and hate.

The 3 Elements of Harmony, the sole defenders of Equestria, were forced to vanquish their master by turning him to stone (though Starswirl was a bit less hesitant than the sisters.) While his spell did not do as he wanted, Starswirl thought he had won. Him being the strongest of the 3 he made the assumption that he would be made leader. He was wrong. Celestia became ruler of Equestria and Starswirl was forced to be her assistant. Starswirl, not pleased with the events that have transpired, continues to work on the spell. Nearly 1000 years later, when he believes the spell is foal-proof, he tries again. The evil magic he had been using increased his already arrogant nature. Thinking he could not fail twice, he confronted the sisters directly.

Starswirl uses the spell on the sisters, hitting them this time. After nearly a millennia of planning, however, the spell still fails. This time, instead of swapping a personality, the spell swapped destiny. Once the smoke cleared, Luna discovered she now had control of the moon, while Celestia had the sun. When confronted by the sisters, Starswirls' anger at his own failure, coupled with the years of dark magic, drove him over the edge. Without warning, he underwent a physical transformation to make his outer appearance reflect his own twisted, evil mind. He became more smoke than flesh, and his eyes turning a sinister crimson with purple smoke billowing from the sides. He rampages, destroying part of the castle then rushed to the nearest kingdom, the Crystal Empire, to enslave its people.

Celestia and Luna travelled to the Crystal Empire to try and reason with their old friend. When Starswirl attacks them on sight, they realise he is gone. They use the remaining Elements to defeat him, but not before he casts 2 spells and completely shed his former identity. The first spell was to put a collective amnesia upon the crystal ponies, making them forget life before his rule. The second spell brung the Empire down with him to his prison, eternity in arctic ice. After the spells are in place, he sheds his former name of Starswirl. " You can never get rid of me Tia." , he says while being sealed in his ice prison."I will always survive. I am everything dark and evil. I am gloom and somberity. I am corruption and power. I. AM. SOMBRA!

With that, Celestia and Luna used their magic to remove Sombra's wings and banish him for eternity, Luna rushed away to alert the country of Sombra's betrayal and defeat. She did not get very far before she was stopped by her sister. Celestia explained that the ponies of Equestria can never know about what happened. First Discord, then Starswirl, it would appear to the subjects that Celestia is eliminating all threats to her rule. As both Discord and Starswirl were loved by everypony, it would begin a revolution if ponies began to think like that. But Celestia had a plan.

She would place the same collective amnesia spell that Sombra used on her own subjects. She hoped it would leave their memory of Starswirl as that he was an eccentric inventor with a long, flowing beard. This would allow people to forget about him, thus preventing a rebellion. Luna, however, saw it as unethical and wrong. She threatens to reveal the truth even after the spell is placed. When she cannot spark the memory of the Equestrians, she became angry. She made an agreement with her sister: They would fight and if Luna won the spell would be lifted. If Celestia won Luna would leave Equestria for 1000 years. Their battle was epic, but when the dust had settled, Celestia was the victor. Luna left Equestria and went to the moon, her moon, to bide her time and wait 1000 years. Celestia convinced the ponies that Luna was jealous of the sun and the day and had to be banished because of her trying to bring upon Nighttime Eternal.

1000 years later, Luna has returned for an attempt at a rematch under the same stipulations. Before Luna can issue the challenge, however, Twilight Sparkle and her friends Rainbow Dash, Fluttershy, Applejack, Pinkie Pie, and Rarity, the now 6 users of the Elements intervene. The Elements show Luna visions, visions of what would have happened if the Equestrians learned of Starswirls' secret. Death and war and hate everywhere. Canterlot was rubble, and all of Equestria was burning. Wounded ponies and burning corpses littered the streets. The face of the planet now riddled with craters, making it appear as a second moon. After that startling vision, Luna accepted Celestia's decision, asked for forgiveness and was returned her status of princess.

After that Twilight had many adventures defending Equestria from evil like Discord, Chrysalis, the queen of the changelings and Sombra himself, forced to live his life as a normal unicorn. Twilight then ascends to alicorn status after completing the spell that Starswirl started, but could not complete. And that is the end of the story. Or at least, it would be, had Princess Celestia not saved Sombra and kept him in a dungeon after Twilight defeated him.
