It's been a while after the new alicorn princess has ascended to her throne. Twilight was still yet to learn many more spells and secrets about the world around her. It seemed like something was missing in her mind though... she wanted to know all the magic she could, since she had the power. One day, she set out with the elements of harmony on a journey to a newly found area of the world.
This land had two levels, the ground layer, which was made up of a large forest structure, and a cloud layer which a large tree reached up into. They all traveled up by either wings or hot air balloon, so they could stick together.
The further into the sky they got, darkness took over their vision. The other elements saw this and felt it necessary to leave, yet, twilight wanted to go forward, something was pulling her in to the large tree in the middle.
She tapped the cloud with her hooves. It was solid like cement, yet it still floated around.
"The clouds here, girls, it's different..." Pinkie pie, being inquisitive, taps the cloud with her hooves too, and then jumps out, knowing the others would catch her if she fell. Luckily, she didn't.. and this cloud certainly was different from the ones back home.. and they were not able to be controlled by pegasi either.. even if twilight, rainbow dash and fluttershy tried as hard as they could.
The girls hop off, and cautiously follow their new princess to the tree branches. A voice comes to twilight only, sounding deep.
"You are only to come in, and collect your well earned magic. But hear this, if any of your friends come in, they die."
She looks back at the others, repeats the message, and after being accepted to go forward, she walks closer to the tree, a invisible portal taking her in, pushing her into another place.. another kingdom.. It was surrounded by the same tree's large branches, skylight being blocked out by the leaves. She walks to the castle, which didn't look too different from the Crystal Empire's, but was a tree instead.. not very weird in this kind of place..
The doors of the dark houses were locked, so she continued walking into the castle, up to where the crystal heart could have been if it were the crystal castle. There is a book there, on a stand. It catches her eye, and somewhere in her mind, something tells her to read it before taking it, just to see if it realy does work.
She flips the book open, and at the first page she reads, she starts translating the words on the page into words from her mouth.
A dark magic encircles the castle, representing a fire of a red, purple colour.
She tries to ignore this, and keeps reading out loud. The magic grows, and starts to form a cloud behind her. Every time she read a word, it grew, and started to split, and starts to crawl over her, now trapping her so she would not be able to escape at all.
The reading was mind controlling, making her ignore everything around her, letting herself be taken over by the dark forces, otherwise known as the nightmare forces. This was the land of the nightmares, the dark species. Kind sombra once ruled here, before taking over the crystal empire. Crysalis also once lived here, with her minions, trying to find a new race to impersonate. They moved again, since they found out a new source of energy, Love. Discord once also lived here, with other 'unusual' creatures who looked as if they were made up of different animals too. And, Nightmare Moon, otherwise now known as princess Luna, found this place as sanctuary, a quiet place to come too, and feel wonderful all at the same time, in darkness, something she loved and wanted the whole world to see.
Twilight, on the other hand had different conections to this place.. Magic.
She read the last few words of the spell, and was embraced by the nightmare forces completely, knowing that if she were not around her friends, she would not be able to escape.
Her coat turned black, and her cutie mark lost it's white stars, and her hair turned into mist, much like the nightmare forces around her.
"much better" she walks through the circle of fire, and leaves the way she came.
part 2
The regal sisters, after all this time, had resumed their lives like it were before nightmare moon.
The princesses happily did their duties of lifting the sun and moon into the sky, and keeping harmony.
Luna had finaly became used to her new home, and developed their language and cultures.
She has the power to walk into dreams. This disturbs a lot of ponies, after the word gets out that she can.
She is sought to as creepy, and this bends the way ponies look up to her. She has to earn everyone's trust now, which is kind of a probelm, because they still remember how she was a bad guy just 2 years ago...
Around this time, Celestia was to go to sleep, and let her sister watch over her kingdom for the night.
As Celestia walks into the throne room, a loud sound is heard, and what sounded like 5 bodies thumping onto the ground.
"Princess.. why haven't you read any of my letters..? Why haven't you responded..? Are you too BUSY to care about me?"
The sun goddess had no idea what twilight was talking of. She always replied back.
suddenly, it seemed like an earthquake had erupted. A black dragon with green eyes and the same purple mist roared outside, and smashed through the castle front, revealing the chaos of the city behind him.
"It was quite easy to take care of him, he's at his true state now..." Twilight saw the dread on the sun goddesses face.
"And now, it's YOUR turn." the mist shot at the goddess, engulfing her and trapping her. She had done nothing, since twilight already had control over her, being one of the most powerful living creatures on the planet.
Twilight smashes her into the ground, making her outcold, and then makes her dissapear. "bye bye.." she smirks, and sits on the throne, awaiting the next princess.
The crystal empire was trapped off, the dark magic now resuming it's fight to take over it, and the inhabitants inside fighting to defend.
Nopony could stop this.. nopony could stop the princess of magic, somepony who could control mostly anything in their world.
Luna hears the commotion, and decides to investigate. She runs down to the throne room, a large gust of wind erupting from it.
The suspicion was correct. She couldn't sense her sister anywhere near her.. only something so farmiliar it brought back horrible memories. She gasps, and runs through it's doors, meeting the nightmare infront of her.
"Twilight Sparkle!" she flinches as the dark magic tries to touch her. "WHAT ARE YOU DOING?!"
"Doing my duties... The Nightmare Forces miss you, dear. Why won't you come back?"
"You were the one who cured me of that cancer. Why would i want to go back to it?!" she stomps on the magic, breaking some of it.
Luna knew this magic, and could control it herself still, with experience.
Twilight stands, and flies down to Luna. She circles her, examining the threats. Luna didn't look very happy.
"Good then, i can have this all to myself." she struggles, as she tries to cover her in the magic.
Luna breaks out, and starts attacking back. Their forces looked equal.. but Twilight had been granted much more power with her new status as 'The Dark Queen'. As their magic touches, a void is created. Whoever got in it first suffered what was on the other side.
Luna starts to struggle, and the nightmare forces starts to pull her into the void, trapping her.
"NO!" she is pulled in, and the void explodes, growing in size, and a blinding light is replaced for the world.
