Celestia, Luna, and Sol were born in an old castle deep in the heart of the Everfree. Celestia; was 2000 when Luna and Sol were born. Sadly; about 500 years later their parents disappeared suddenly. Celestia was left to take care of her younger siblings; and soon met a young creature named Discord; who she bonded with. However; as years went by (about 400 years or so) as her and Discord grew closer and closer; he soon suddenly left and the world turned into chaotic mess.
Celestia and her siblings finally left their forest home to find that Discord had finally fallen into his chaotic ways and had taken over Equestria. Celestia was horrified at what had happened and although she had become close to him; she wouldn't stand for what Discord was doing to the poor ponies. After being taunted by Discord; Celestia and her younger siblings came together and used their magic against discord; thinking about how close they were and all the things they had done together. As they used their magic; it mixed and turned into a suddenly rainbow; washing over Discord and turning him to stone. The three Alicorns soon found six gems had been crafted by their magic; which they soon called the Elements of Harmony which they stored away to be used in their times of need.
However; only about 90 years into their reign, Sol started to become sick and it only grew worst and worst. Celestia; Luna, and Sol had all talked about taking over the job of raising the moon and sun as their parents had done so before they disappeared; and it was becoming to much for the unicorns to do. Luna and Sol were to take over the jobs; but because Sol had grown sick; Luna pleaded with Celestia to raise the sun instead of Sol, just until he was better. Celestia soon agreed and started to raise the sun while Luna would raise the moon; both gaining their cutie marks; much to the dislike of Sol as he was the one that should of gotten a cutie mark for raising the sun.
50 years after Sol first becoming sick; and almost dying,had grown much better and had returned to ruling with his sisters but Celestia continued to raise the sun. Soon, an Alicorn named Avan showed up at their doorsteps and they happily accept him. Avan soon grew close friends with Luna and Sol.
Snowdrop happens. (You should listen to
this song just cause)
About 50 years after Avan showed up; Luna met the lovely Prince Sombra of the Crystal Empire and soon married. However; after 5 years of Luna being married; she came to Celestia pleading that something was wrong with Prince Sombra and that he was getting in far to deep with his studies; but Celestia pushed Luna off to the side as she had to take care of Equestria and she was sure that Prince Sombra would be fine. However; not long after Luna left, she returned to claim that when she was asking for Celestia's help; Sombra had tapped into the power of the Black Crystals, went insane and took over the Crystal Empire, making himself a King.
Celestia, Sol, and Luna went out to the Crystal Empire where they tried to reason with Sombra; and without a choice; used the Elements of Harmony against him and trapped him in the ice as nothing more than a Shadow. They all returned to the castle; with Luna barely speaking a word to Celestia. Luna turned into Nightmare Moon; they fought...See above for more details...
After returning to the castle; Celestia and Avan got into a fight over the fact that Celestia had trapped both Luna and Sol. However; the next day as Celestia went to go explain her reason for doing so to Avan; she found that he was gone.
During time, about 980 years after the trapping of Nightmare Moon; she made a young pegasus named Cadance an Alicorn. I really don't know much about that so...yea.
However; about 5 years after making Cadance an Alicorn, she saw a magical outbrust from the Celestia's School for Gifted Unicorns. She entered to find a young unicorn having a large magical outburst; one that Celestia was easily being able to stop and made the young unicorn; Twilight Sparkle; her own student at the school.
About 15 years after making Twilight her student; the day came when Nightmare Moon escaped. On her way to Ponyville for the celebration, she was stopped by Nightmare Moon attacking her; and realizing she couldn't fight her because she couldn't hurt Luna; she let herself willing be trapped in the sun. During her short time in the sun; she realized that Sol was missing like she was expecting; figuring he would have escaped with Nightmare Moon, but he had been gone for 15 years or so from the sun.
She soon escaped when the sun started to rise (from a spell Celestia had placed on it moments before she left), she found Luna had been freed from the Nightmare Forces and welcomed her back as ruler of Equestria. And then you all should know what happens from there. Two years later; she turns Twilight Sparkle into an Alicorn.
