It's been a few weeks or maybe days but for Sparkle Sky it was the strangest span of time she ever lived through.
Now understand the events before that day where basically the same old Canterlot princess stuff, like mingling with the nobles, Checking out the cute Guards, gossiping about life. Then that day came, a day most forgot about The Thousand Year Exile of Night Mare Moon was about to end. For the most part No one knew that day was here, No one that is but Twilight Sparkle and one other. The urgent letter appeared in a puff of red smoke in front of Princess Celestia, detailing all the calculations and warnings. Celestia Looked concerned and had the whole Canterlot Populace preparing for the return of Night Mare Moon. The Castle and Canterlot prepared for a day that no one wanted to happen. Down at the foot of the mountain in Ponyville, no one really took Twilight Sparkle's warning seriously and went about their own buisness.
Sparkle Sky on the other hand was excited and looking forward to seeing her Best Friend again, a thousand years is a long while to be without your friends; and Sparkle was probabaly the only friend That Night Mare Moon had left.
So why did this one alicon feel such a friendship to the most evil pony out there? Simple: Sparkle Sky and Luna where born almost exactly at the same time on the same day. From the moment they where born they where best of friends. Being friends with Luna also meant you where Celestia's friend as well. For many years the three young ponies did everything together even get their Cutie Marks all in the same day. That day..they day they all discovered their gifts was the very last day they all where happy and together. Celestia's Mark was the royal Sun mark, wich sealed her place..She was deemed Celestia Queen of Equestria. Soon Luna fell into the shadow of Celestia, and celestia lost contact with her beloved sister due to the whole queen buisness.
Sparkle alone Witnessed the sadness, abandonment , anger and jealousy that consumed Luna and transformed her to Night Mare Moon. Sparkle tried her hardest to prevent this transformation, she even went so far as to not request but order celestia to take time off and hang out with her sister. The new Queen simply seemed to have no time to mingle.
Luna's jealousy really got the best of her when she found out, that the beautiful Moonlit nights she gave to the residents of Equestria where never seen as the population was sleeping through the beautiful night. when Sparkle saw how grand the night was, she took the strongest stance she could. She declared her loyalty to luna who had become Night Mare Moon. The Stardancer was closer than friend, closer than sisters indeed some rumored the two night princesses where intimate , this was untrue. Sparkle put the stars in the sky to enhance the Moonlit nights. Then there was a battle, and after that battle "the mare in the moon" appeared. Sparkle couldn't remember what happened after that.
A thousand years passed, and the Star princess lived in canterlot and remembered nothing of those times, except a weird feeling of sadness and loss.
The day that Night Mare Moon returned to Canterlot she kidnapped Celestia, and half the princesses. Her magic had put all the other poniess asleep, all that is But Sparkle as she was needed to decorate the night with stars. Her loyalty to her friend payed off,she was remebered. Then they showed up...The elements of harmony.
The former student of Celestia Twilight Sparkle came to the castle with five friends. She recited the spell from the book,of the elements of harmony. Applejack represents the spirit of Honesty, Rainbow Dash represents the Spirit of Loyalty. Pinkie Pie represents the spirit of Laughter, Rarity represents the Spirit of Generosity, Fluttershy represents the Spirit of Kindness. To bind it all together Magic! The flash and shine dissolved Night Mare Moon leaving Luna unconsious That was Sparkle's Last Memory for a day or so. She had slept for, twenty- four or forty- eight hours maybe longer
