Celestia's Birthday

After five days of agonising wait, the time came for Celestia's birthday, Luna was excited for the party Pinkie Pie has thrown for her sister so she can see how happy her sister will be when she sees how the party has turned out and how the cake looks in all its magnificence, she was told by Twilight Sparkle that she should bring Celestia to the party seeing as how it was a surprise for her older sister, an hour left before the party was due to start and Luna was about to leave to see the final preparations when something caught her eye, she saw her medication laying on her bedside table, she smiled, "Surely the party can't be that stressful after all it is a party," she left to the ballroom to see that her friends had arrived and friends of Celestia she saw another princess she recognised and walked over to her, "Greetings Cadance," Cadance turned and hugged Luna after she greeted her, "Good to see you again Luna," Luna smiled, she saw most of the balloons shaped like the sun and some like Celestia, Luna saw Twilight and her friends and she greeted all of them by name, "Greetings Applejack the Honest, Rarity the Generous, Fluttershy the Kind, Pinkie Pie the Laughter, Rainbow Dash the Loyal and Princess Twilight Sparkle the Magical," she bowed to them and said, "If it were not for you I would not have been freed of Nightmare Moon," they all bowed back in respect for what she had said. Luna looked at the clock and told every pony, "Okay I'm going to get the birthday mare," they all took their places, ready to surprise Celestia. Luna walked towards her sister's room and knocked on it, "Come in," Luna heard the voice and entered, "Happy Birthday Tia my sister," Celestia smiled and was standing in front of her mirror just finishing off putting on her royal attire, "Thank you Luna," Luna walked next to her sister and stared into the mirror with her, "Tia, you'll always look beautiful to me," Celestia hugged her younger sister, "And to you as well Luna, but, have you seen Twilight Sparkle? She is normally the one up before both of us," Luna tried hiding her smile, "Why yes I think I saw her in the ballroom," Luna walked out of the room and Celestia followed her and as Luna opened the door to the ballroom, Celestia was overcome by an array of colourful ponies who all said in unison, "SURPRISE! HAPPY BIRTHDAY CELESTIA," Celestia was taken aback to see so many ponies in the Royal Ballroom.

The party was going well, every pony was conversing and laughing and having a good time,

even Luna who was not feeling so well today was having fun, she was having a discussion with Octavia whose friend happened to be Vinyl Scratch the DJ for the party, "She has very good talent, but, I enjoy the classical music more than any other," Octavia blushed slightly at what a princess said let alone Princess Luna, they continued their discussion until Luna was taken by Applejack to see her little sister Apple Bloom, "Your majesty this here is mah lil sis Apple Bloom," Apple Bloom bowed in being in the presence of Princess Luna who she had not seen before except on Nightmare Night a few years ago, "Honoured to meet the sister of Applejack the Honest," she bowed to the small filly in respect, Apple Bloom was lost for words that she could not believe that the legendary Luna was bowing to her.

"An' this is mah big brother Big Macintosh but we call him Big Mac at the farm," Applejack introduced the large colt and he bowed to his Princess, "Always a pleasure to meet family of Applejack," bowing to him as well, "Lastly an' certainly not least, our Granny Smith," Applejack said bringing her to the old green pony, Granny Smith bowed in respect, "At least now I see where your granddaughter gets her charming personality from," Luna bowed to her and Granny Smith began to chuckle sweetly. Soon Luna was borrowed by Rarity and was introduced to her sister, "Your majesty might I introduce you to my younger sister Sweetie Belle," Sweetie Belle bowed to the Princess, "It's always nice to see Rarity the Generous having her sister with her," she bowed to her as well, Luna then left the small filly

and walked over to an orange pegasus filly with a purple mane and tail, "Greetings Scootaloo it's wonderful to see you again," Scootaloo looked up and hugged Luna on her leg for she was still very small, "It's good to see yo as well Princess Luna," and Luna bowed to her so she could get a better hug from the princess. Luna was all over the party being introduced to ponies, chatting about the future and listening to stories, but the best thing was that a certain topic never arose in a conversation and she was grateful for she had not taken her medication, the time soon came for her to stand in the front of the ballroom and announce the cake, "She projected her voice using her magic, "Fillies and Gentlecolts let's all sing the honorary words we sing for a pony on their birthday and let's welcome Celestia's cake," the ballroom erupted in a unison singing happy birthday for Celestia and she was happy when she saw her cake as well, the cake was the sun of her cutie mark and her head rested on it, the Royal chefs and bakers including Mrs Cupcake had put a lot of effort into it.

After the candles were put out and the cake sliced the party went on and gifts were given to Celestia, "Gifts! Oh dear I forgot mine in my room," Luna left to get her gift and when she entered her room she forgot where she put it, since she had to hide it from her sister, she suddenly remembered where she put it, in the draw next to her mirror where she kept her tiaras, when she finally got it she looked into the mirror and jumped back when she saw what was staring back at her, again half her face was with her short blue hair and her normal look and on the other was Nightmare Moon smiling, "No... no... it's not real... you're not real get away from me," suddenly she looked at her gift and realised that she needed to give Celestia her gift she ran back to the ballroom where Celestia had already opened all her gifts and they were new shoes, new tiaras and just other jewellery, but, none of them compared to what she had bought her sister, Celestia turned to her sister and asked her, "What about you Luna, don't you have a gift," Luna walked over to her sister and presented with her gift, when Celestia carefully removed the beautiful wrapping paper with her magic she held the box and opened it and out levitated a beautiful golden necklace with a beautiful yellow jewel in the middle of a sun shape, Celestia hugged her sister and said, "Thank you Luna it is truly beautiful, she used her magic to remove the one she was wearing and replaced it with Luna's.

Every pony looked on in awe as the sun caught the gem in the perfect position where it shone like the sun and many ponies thanked Luna for the gift, Luna appreciated that not only her sister liked it, soon it was time for most ponies to leave for home, but the elements of harmony decided to stay the night and help clean up the party with a few ot their other friends, unfortunately, Apple Bloom, Sweetie Belle and Scootaloo had to leave as well because they were too young to stay up so late so they arranged to head over to Sweet Apple Acres and have their own sleep over. After the goodbyes were said Luna turned to the ballroom and saw the elements of harmony and a few others staying the night.

Luna sighed in relief as she finally gave her second gift to Celestia, a most beautiful night that was only fit for the most special occasions and tonight was one of them and Celestia was right there to see her create the beautiful night, Luna and Celestia returned to the ballroom to help clean up the party and put away the left over cake that they would have for breakfast the next day, the few ponies that stayed to help and clean up included Lyra Heartstrings, Octavia, Vinyl Scratch and Bon Bon and Princess Cadance, they would be spending the night in the castle as well, before Luna could leave the ballroom a voice called to her, she turned her head and trotting after her was Princess Cadance, "Yes what is it cousin?" Cadance was Celestia's adoptive niece after all, "I wish to speak with you alone," Luna nodded and led Cadance to her bedroom, after they arrived at her room she turned to Cadnace, "What is it Cadance, what is so important?" Cadance walked to th ebalcony and said, "I often wonder what it must have been like to be banished onto a desolate place away from your home where you grew up..." Luna began to feel uneasy and quickly took her prescribed medication to try and calm her down, Cadnace continued, "Worst of all must have been that your own sister had to banish you and not even she could understand on how you felt about ponies not loving your gorgeous nights..." as Cadance continued talking Luna tried breathing in and out slowly and deeply as not to be angry she then left the room slamming the door as she left, Cadanec turned around and saw Luna was gone, as Luna tried to flee from Cadance she was caught by Twilight, "Whoa Princess Luna what's wrong," Luna only looked at her and continued to gallop away from the alicorns, she entered the throne room and tried to calm herself again, Cadance stepped into the room to see Luna backing away, "Cadance leave me alone, please for your own good," but, Cadance only got closer, "Please Luna just tell me, why are you afraid to tell me about your past, I do not know much about it I'm just curious," Luna felt something in her again and suddenly lost it, she collapsed to the floor crying, then without warning she rose up and spoke in her Royal Voice, "DIDN'T YOUR FOAL SITTER EVER TELL YOU THAT IT'S RUDE TO SPEAK TO A PRINCESS LIKE THAT, WE ARE NOT YOUR FRIEND, WE ARE THE PRINCESS OF THE NIGHT, WE ARE THE NIGHT TIME!" Cadance became frightened, "Luna you're scaring me," Luna began to grow in height matching that of her sister's, her wings began to change, her teeth became fangs, her mane became dark and flowing with the stars held within it, armour had appeared on her body and when she opened her eye her pupil like that of a cat's and she turned a black colour and when the smoke had settled she emerged she stated in the Royal Voice, "THERE CAN BE ONLY ONE RULER OF EQUESTRIA AND THAT RULER IS ME... NIGHTMARE MOON," she began her evil cackle and saw a frightened Cadance and lunged towards her flying at full force.

Meanwhile in the ballroom the room opposite the throne room the ponies were just about finished until suddenly Princess Cadance crashed through the door, all the ponies in the room including Twilight and her friends were all shocked when they saw Cadance's bruised body and messed up hair, they all turned to see what had made the hole and they saw to their disbelief Nightmare Moon hovering through the broken door, all the ponies gasped as they saw her, "That's right you foals I'm back and did you ever think that you could get rid of me?" she began to cackle again, suddenly out of no where Celestia had stepped into the light "Sister remember who you are, you are Princess Luna not Nightmare Moon," Nightmare Moon only laughed, "Oh my dear sister you have plenty to learn and the first thing you will learn is that I am the one and only Princess of Equestria."

Celestia flew towards her sister and tackled her out of the castle's roof where they began to do battle, shooting magic at each other, both dodging the other's shots for they were equally matched, meanwhile back in the castle Twilight had gathered her friends and told them, "Girls this is terrible Nightmare Moon has returned and we need to use the elements of harmony again to stop her, she and the others ran to the study where the elements were kept, after the elements were on the respective ponies they rushed back out of the castle into the courtyard where they saw that Nightmare Moon and tackled Celestia to the ground and they were fighting in close combat now, a flash of light sent the two alicorns flying backwards and they readied to charge the other they galloped towards each other trading blow after blow trying to weaken the other, both were bruised and dirty and both their manes were torn and damaged. Twilight and her friends could do nothing except watch what was unfolding before them, they couldn't use the elements of harmony because they might hit Celestia instead of Nightmare Moon. Celestia managed to parry Nightmare's attack, but, was struck by a rebound shot in her armour, Celestia exasperated in pain, it had hit her in the gap between her armour and her shoulder, Nightmare seized her opportunity and shot up towards the sky holding Celestia in her hooves and then plummeted back towards the ground hitting the ground beneath them and when the dust cleared Twilight saw Celestia unconscious in a small crater and Nightmare Moon was standing over her panting and had a smile of victory on her face, Twilight grew angry, "That's it Nightmare Moon, this ends now," she and her friends concentrated and the elements of harmony began to glow and a massive beam was travelling towards her, Nightmare screamed, "Nooooooooooo!" and when the dust settled again, the six friends saw an unconscious shape on the ground and they didn't know if it had worked, Twilight walked towards the unconscious mare and looked over her, suddenly an enormous flash erupted from her horn and Twilight was knocked back into all her friends, Nightmare Moon rose into the sky cackling, "You foals! that does not work on me anymore for I have grown stronger during my absence and as for those..." she used her magic and removed the elements of harmony form their owners necklaces and crown, she laid them on the ground and descended and stepped on every single one of them and leaving the element of magic for last and she crushed this one as well.

Nightmare Moon rose into the sky once more and used the Royal Voice, "NOW THE ELEMENTS OF HARMONY CANNOT STOP ME NOW AND EQUESTRIA WILL BE COVERED IN EVERLASTING NIGHT TIME FOR I AM THE ONLY PRINCESS OF EQUESTRIA NIGHTMARE MOON!" she began her evil cackle yet again. Twilight couldn't believe her eyes on what she had just seen, the elements of harmony gone forever she could do nothing now Nightmare Moon was truly unstoppable now just then Celestia rose up from the crater and pointed her horn towards her sister, "I'm sorry Luna but you have forced me to do this again," she said before she shot a white beam towards Nightmare Moon sending her back towards the moon Nightmare Moon screaming in anger, "I'LL BE BACK!" Celestia collapsed on the floor after that immense power leaving her body. Luna woke in a strange place where she was surrounded in black she looked around, she called out softly, "Hello?" she could hear the soft echoes, she walked aimlessly and saw a figure and decided to walk towards it and she saw Nightmare Moon screaming from somewhere she recognised, she began to cry to herself, "No, not again... not again... how could Tia have done this to me again?"

To be continued...

A/N: Whoa even that was hard to write so that's it Nightmare Moon has been banished to the moon again but what will happen when she returns? With the elements destroyed nothing will be able to stop her and Celestia almost died from a close encounter battle, so please Read and Review and tell your friends to do so as well, I wish to mention that another Fanfic will be in the making and it was requested by retro mania but I would not want to spoil any thing just yet ;)
