Chapter 1
Princess Luna was in her room enjoying the peace and quiet of the night she brings forth every evening in Equestria. The night was still young; Luna had raised the moon not even ten minutes ago, and she could not seem to sleep. While laying in her large and extravigant bed, she started thinking about the events that led her to where she was now.
Over a thousand years ago Luna had grown jelous of her older sister Princess Celestia; the alicorn pony who brought out the sun in the mornings when Luna lowered the moon, because the ponys of Equestria thrived under the suns beams. While during the night Luna brought forth the citizens of the land slept. In her contemt for her sister, she became the terrible being known as Nightmare Moon and attempted to shroud the land in eternal night. Her sister Celestia reluctantly used the Elements of Harmony and banished Nightmare Moon in the moon for one thousand years.
Then one year ago a unicorn pony named Twilight Sparkle; studing under Princess Celestia, learned of the imminent return of the evil mare during the Summer Sun Festival. When Twilight tried to warn the Princess of the impending return of Nightmare Moon, she sent her to Ponyville to overlook the Festival preperations and make some friends.
On the dawn of the Festival, the Princess was nowhere to be found when it came time to raise the sun. Nightmare Moon had revieled herself to the shocked ponies of Ponyville and declared that the night would never end, but Twilight Sparkle was determined to stop the villian. Nightmare Moon learned of Twilight's plan to use the Elements of Harmony against her.
Twilight went in search of the legendary Elements, along with her newfound friends, Rainbow Dash, Pinkie Pie, Fluttershy, Rarity, and Applejack. The six young ponies braved each obsticle set by Nightmare Moon with thier own skills. They reached the Elements and prepared to figure the petrified Elements, when they were about to be teleported away with Twilight along with them.
After a brief attemt to make the Elements work Nightmare destroyed them and her victory looked complete. There was one problem the Elements were really linked to each of the young ponies (Pinkie:Laughter, Rarity:Generosity, Rainbow:Loyalty, Apple:Honesty, Flutter:Kindness, and Twilight:Magic), using the power of the Elements they defeated Nightmare Moon. Princess Celestia was freed and so was Princess Luna, whom lay amongst peices of the armor that once was Nightmare Moon.
Now here Luna was laying in here room, glad for things to be returned to peace. There seemed to be a breeze that sent a chill down Luna's spine. She looked towards the windows to find that they were closed. The small princess shrugged and figured that she must have imagined it. She continued thinking about past events, including the most recent issue with the evil trickster Disc-
/Luuuuuuuunnnnnnaaaaaaaaaa......
Luna whipped her head around in search of who or what called her name. The voice was strangely familier, but she could not put her hoof on it.
/Luna... I have returned.... let me in...
The Princess froze in horror as she remembered who the voice belonged to... NIGHTMARE MOON!
"I-it c-can't be! Y-y-you were destroyed! By the Elements of Harmony!!" she gasped in disbelief.
/Oh, but it can be. Dear little Luna, you can never be rid of me... EVER. Now, let us take our rightful place as sole ruler of those worthless ponies in Equestria!
"No!! I won't let you harm anypony!!! You shall not have your way Nightmare Moon!" Luna exclaimed, her heart rate accellerating in dread. Nightmare Moon turned a deaf ear to the little alicorns preaching.
/But first, before we can start reclaiming our dictatorship.... we need to take care of those miserable little whelps who stopped us last time... Yes!
Luna's eyes widened in shock.
"W-what are you planning to do!?" She stutterd.
/Watch and find out... Now give me the body!!!
Princess Luna gasped as she felt a force within her seemed to be pushing its way out of her very being. She thrashed in her bed in pain as she tried to resist Nightmare's assault for dominance. As her thrashing went on her front hooves collided with a vase on the nearby nightstand, sending it crashing to the floor.
Out side there was a pair of Royal Guards standing out side Princess Luna's sleeping quarters. They were standing as stiff and unmoving as Discord's statue outside in the royal garden. The two guards were suddenly alarmed when a large crash came from the young princess' room. The duo reacted immidiately as per their training and burst into Luna's bedroom expecting a threat. Instead they found the princess thrashing in her bed and they froze in confusion. Luna suddenly collapsed on her bed and the two guards rush to her side.
"Princess Luna!" the bigger of the two exclaimed.
"Are you alright?" the smaller guard asked worried.
"I'm just fine."'
The guards sighed in relief.
"But i'm afraid there is something wrong with you..." Luna looked up with a twisted expression.
"E-excuse me m'lady?"
The door behind the two guards closed magically and a faint clicking of the lock could be heard.
Luna stood up and advanved on the guards, who backed up nevously from her. Then she sprang into action.
Luna's horn glowed with magic and the bigger guard was sent flying across the room and was pinned to the wall. The smaller guard gulped and dropped to his knees in terror. The princess smiled gleefully at the guard who was now whimpering in fear of the little alicorn.
"Y-you're not the Princess!"
"My, aren't you a smart little colt. Indeed I am not your pathetic little weakling of a princess... I am Nightmare Moon!"
The guards eyes widened in terror as he felt a warmth spread from his flanks. Nightmare moon laughed as she formed a blade if magic on her horn. She lowered the horn and cut into the colt's side, puncturing the guard's protective armor like butter. He screamed in pain as the evil mare pumped magic into the wound, coursing it through his body rupturing his organs slowly one by one, all the while using magic to keep him from blacking out. She then conjured a parasprite in his stomach letting it eat it's way out of the colt's body while he was awake the whole time. Blood was pouring out profusely from the cut Nightmare had made.
Satisfied she turned to the bigger guard and smiled listening to the smaller guards screams of pain, which was music to her ears
"You'll never get away with all this Nightmare Moon! Celestia will-"
"She'll do what!? Call her little Element holders to stop me!? HA!! I will already have taken care of those little mettlers myself!"
Nightmare Moon grinned as she advanced on the remaining guard. The guard started to cry and think of his wife and 5 year old little girl. Nightmare just relished his fear, sadness, and regret.
