The rest of the day went by rather quick in Airy's opinion. More reading while Radiant and Sombra worked, before dinner time (when she realized that Thunder Shield was Glimmer's husband, not brother. Glad she hasn't accidentally voiced her first opinions out loud), then more reading as she listened Sombra and Radiant theorize they'd need to create a new, more specific spells to harness emotions, instead of just trying to dumb them into preexisting ones.

The day ended as Sombra and Radiant reported their progress to Princess Amore, who decided to give them a night off to rest properly. It was at this point that Swift Clean decided to guide her to her new room, where she apologized in advance if anything inside offended her.

It was pretty good room though; two tables in opposite corners from the door, one which held her bed (a brand new, repurposed cat bed) with bed linens, blankets and pillows just suitable for her size. As she sat down on it to test it, it felt like she owned her personal Queen sized bed. She reassured Swift that she wasn't offended, as it was more convenient to make things her size, rather than try to use over-sized furniture.

On other table, behind a curtain blocking most of the view, was a washing bowl and several tiny (well, to her they were large) towels, though she'd need to ask help with the water from a maid or the guard in purple crystal armor (a light brown furred stallion with light green mane), who introduced himself as Glint Hoof.

Apparently, since Airy's so small, Thunder Shield decided to give a guard duty for one of the newer recruits, basically serving as an assistant to her.... though to Airy, it was clear that she was under observation. Still, she pretended she didn't know that, genuinely thanking the guard for the help he'd be offering her. She was small (in this form) so it would be awful to manage doors and such.

Glint had also explained that tomorrow morning, a mare by the name of Shard Tackle would be taking the morning shifts, while Glint worked the night shifts, explaining it as 'training to escort/guard ponies of importance' that Thunder had chosen for them... though in truth, Airy silently wondered what the two had done to deserve such a boring punishment.

Swift Clean had also put a nice carpet on the floor, as well as a book case (which stood empty right now) and a simple work desk, with a stack of papers, ink and a quill ready, should she want to write something down. Airy wondered if she could introduce modern technology to this world; it would make some quality of life improvements.

However, as the room was still mostly empty, Airy requested Swift Clean if she could add a real bed to the room the next day. Of course, she had to quickly explain that it wouldn't be for her, but for any guests she might have or a future roommate, considering that it would be a waste not to consider it at least; she was quite small, so sharing a room would be practical in her opinion.

In reality, it was because she considered a point in the future, where she might sleep in her larger forms.

Finally, Swift Clean introduced her to a small string set next to the door, which was linked to a small bell on the other side of the door, so should she need to exit, she could ring the bell. Airy had tested the string, to check whenever she could pull it enough to ring the bell, after which she was satisfied with foresight Swift Clean had.

As she said her good nights to both Swift and Glint, the door of her bedroom closed, leaving her alone with the night lights of the sky coming through the mostly-drawn curtains and her own soft glow.

After a long first day of what would probably be long decades to come, Airy yawned as she flew to the window, sitting on the window sill as she looked down at the city, before gazing at the beautiful night sky and full moon.

She wasn't sure how long she just sat there, watching the night sky, until she grew sleepy and retired for the night in her new bed, removing her clothes and underwear before enjoying the feeling of bare sheets against her skin...

As Airy slept, in a faraway land down south, A princess of the night and dreams sat on the throne, with light of the night sky illuminating her dark blue coat as her sapphire blue mane glowed, covered in tiny light spots as it moved as if in intangible breeze, while her sister and subjects once more slept peacefully for the first time after months of turmoil caused by Tirek. As the night princess turned her attention from the empty throne room of their castle in Everfree forest, she began to relax as she wondered the events of the last few months.

Finally, with the help of Scorpan the twin sisters, Celestia and Luna, had managed to defeat his older brother Tirek and restore the magic he had stolen from their subjects. Sadly, while Scorpan's change of heart had been due to his initial befriending of Star Swirl the Bearded, he did not know what happened to Star Swirl between the time they met and the time he had come to warm the princesses of his brother's intentions.

According to Scorpan's own words, because the travel to his homeland and back to Equestria had taken nine years, upon his return he had spent the first three weeks attempting to find Star Swirl, to warn him of his failure to convince his brother of abandoning his plans of conquering Equestria, only to discover that his first pony friend had simply disappeared mere weeks after he had left to return home.

Still, as she and Celestia said their goodbyes and thanks to Scorpan on his journey back home earlier that day (technically yesterday, as the midnight had passed), the two sisters were left to silently wonder; if it was not Tirek (nor Discord, as they had discovered in their first fight with him a year ago, prior to finding the Elements of Harmony), then what had caused Star Swirl to disappear nearly nine years ago?

Luna let out a sigh, before she closed her eyes and entered the dream realm, searching for the nightmares she knew awaited her. Tirek's villainy throughout Equestria had left many with nightmares of magic stealing centaur, so while her sister took care of rebuilding that which was destroyed in the real world, it was Luna's task to heal the mental wounds left upon the sleeping minds of their subjects.

Hours fly by as the night princess erased Tirek again and again from the nightmares of her subjects, replacing them with more pleasant dreams of friends, family and inspirations.

After a particular filly's dream, where she became an Alicorn (In her dreams only, of course), Luna took notice of the time in real world; the morning was soon approaching, so she made the choice to quell more nightmares the next time, before she traveled to the dreams of the Crystal ponies.

She had intended to visit Princess Amore, to inform her that it would be another few weeks at least before they could make the trip (which itself would take at least a ten days by flight, more so since they were planning to bring supplies for the crystal ponies), when she encountered a strange, yet fascinating variation among the dreams of Crystal ponies.

Her curiosity awakened, Princess Luna entered the dream, unaware of the defenses left behind by the creature's master...

As she entered the dream, Princess Luna found herself fascinated, as she hovered in the air. She was inside a temple of some sort, as a long row of creatures, covered in dark clothing, stood still, each holding a staff with a candle at the top. The line reached from the door all the way to the altar, where a furless creature in white dress sat on its knees, its mane covered head bowed as its claws clasped together in silent prayer.

She recognized the prayer, because she had once seen a Minotaur in similar position, praying to his earth deity. Yet as she turned her gaze towards the altar, what she saw rendered her speechless.

In the air, a giant green crystal hovered, easily the size of four story buildings, radiating with far more power than even the Tree of Harmony had since before she and her sister had removed the Elements of Harmony from it. She was almost sure that this dream was based on memory, rather than figment of one's sub consciousness.

A tiny movement of light at the corner of her eye ended her trance, as she turned her gaze towards the other side of the room; on the opposite side of the row of creatures, a small ball of light hovered, witnessing the dream in progress; while it was too far to see properly, Luna recognized a dreamer when she saw one.

Yet before Luna could approach the creature, the dream world shook as Luna felt a spike of pain in her head; a clear sign something was wrong. An involuntary gasp of pain left her, as her vision went blurry for but a moment.

Sparks of black and yellow energy around her went unnoticed, coming and fading in a blink of an eye.

As her eyes focused once more, she did not have time to search for the cause, as black shadows began to stream around the crystal, slowly enveloping it as the dream constructs yelled out in shock. Luna had but a moment to surround her with a shield, before a force of pure darkness surged forth, snuffing all light within her view.

"Leave or suffer!" A deep voice echoed in the darkness.

The force of impact that followed the voice sends her flying, before light appeared as she crashed in middle of an empty field. Luna quickly straightened herself as she looked around, no longer in the temple but a field surrounding a small village. As she looked around, her eyes snapped to the dreamer; it was observing a creature like the one who had been praying, except this one was shepherding a flock of sheep, with smaller creature at its side.

She however did not have time to process what this meant, as the ground beneath her shook while another spike of pain flickered in her head. This time, she recognized it as an outside force, attempting to force her out, though she resisted... and the dream constructs paid the price.

Once again, she failed to notice the sparks of black and yellow magic, turning the dream against her.

Her gaze fell upon the village, as a pillar of light erupted from beneath the earth, lifting the ground before it sank beneath, creating a massive sinkhole as both it and the pillar of light grew.

Luna had but a moment to take flight, raising her shield as the light hit her with full force, sending her flying once more, while a distant cry from the dream constructs could be heard. She could do nothing, as the light of the pillar was bright enough to force her to close her eyes, burning as if the might of an entire sun was struck against her; another echo of a memory.

"You are not welcome, intruder!" The deep voice once again echoed.

As she once again landed, gasping for breath, Luna took a moment to gather her breath, as she looked around. She stood in a stone platform, surrounded by darkness, with a large pillar of stone in front of her, split in two as a sense of sickening evil filled the air, a red light glowing between the two parts of the pillar.

Yet as she spotted the dreamer once more, as the dreamer hovered above what looked like the shepherd, before entering the red light ahead "Wait, stop" Luna yelled, her cries ignored as she took few steps towards the light, only to stop as the 'shepherd' turned around.

It looked like the creature from before, yet it wasn't: A dark, maleficent being that merely used the form as a disguise. Yet, as this memory of evil spoke, she heard the same voice as before; "You have intruded far enough, mortal! Leave now, or suffer our wrath" The deep, echoic voice spoke again, this time from the lips of the shepherd.

"We demand you surrender, foul demon. We must save the dreamer from your corruption" Luna yelled, her horn glowing as her spell struck the memory, only to reveal that it did nothing, as the creature shifted its form in an instant, this time appearing as the creature, who had prayed before the giant crystal.

"Yet it is you who seeks to harm 'the dreamer'. Your power means nothing to a god. Leave now, for the power of the celestial shall not be yours!" The deep, echoic voice replied from the lips of the priestess.

"We don't care about this 'Celestial' or its power. Now begone, demon!" Luna yelled, as she struck again, this time striking until her head felt light from the effort. Usually, such a show of power was enough to collapse the dream, yet it did not even affect it, let alone the monster in front of her.

Yet as Luna's horn glowed once more, the spell died as the creature shifted a final time; This time, it was her own form, standing tall and proud with emotionless expression.

"I am no demon, mortal. I am Ouroboros, the god of destruction. Once, I laid worlds to waste, as I sought to invade the Celestial Realm, home of the greatest civilization to exist; home of the gods. I have fought the champions of the Celestial's at their fullest power, bringing them to their knees. Now, I shall bring your realm chaos, hatred, fear, jealousy, corruption, brutality... excitement!" The deep, echoic voice yelled out from the lips of her double, before a bright red light surrounded them.

Luna shielded her eyes, before blinking as her surroundings had changed; now she stood in a different platform, levitating in a red void, as the skies were covered in rifts, which showed hundreds of worlds from above. However, Luna did not have the time to enjoy the view, as she faced the monster before her.

"Now, it is time! Here, in the infernal realm, you shall meet your end!" The deep, echoic voice once more spoke, as the demon's true form was revealed; A large creature, with four clawed hands, a red gem at the lower face and a large horn on its head, where the two yellow eyes pierced at her at the base. She could see the tentacles emerging from behind its back, though Luna ignored the rest as she focused solely on the creature's eyes, gazing down at her.

The sheer power she felt from the creature rivaled the memory of crystal, even surpassing it with great deal. As the creature moved its arms, a magical symbol appeared behind it as a whirlwind of magic gathered at its arms, before it directed it at her. Luna gathered her remaining strength to raise a shield just in time as the attack connected, bringing her to her knees, as a spike of pain once more pierced her head, causing the shield to collapse.

Teary eyed, Luna desperately gasped for breath, before her focus finally focused on the left shoulder of the monster, where a familiar ball of light hovered, failing to notice the yellow and black sparks around her.

Luna's eyes widened, as she looked at what she thought was a demon again; A realization shook her, as she understood that this thing was not a demon possessing it's victim, rather merely a replica constructed by the dream from a memory. That alone said much, as even a memory of such a being was invincible, as long as the dreamer dreamed it so.

"Dreamer, please stop this. We only intended to help, not steal your secrets" Luna yelled, as she reached her hoof towards the dreamer; Every encounter she had here, in this bubble of a dream, had been to drive her out, though she has mistook them as a sign of a great demon invading it.

Though she still couldn't see the dreamer, she could tell that it had turned towards her. For a brief moment, she felt as the pressure of pain started to vanish, before it redoubled once more as the dreamer answered.

"Remove her" Dreamer's high pitched voice spoke, as Luna's eyes widened in total fear.

The deep, echoic voice of the memory echoed with its laughter, as it spread it's claws; snakes of blue energy surrounding the hundreds of worlds in the sky, before they exploded with a mighty fury, bringing with them untold power as this 'Ouroboros' pointed his arms towards Luna.

And with a flash of her horn, the princess of night and dreams fled the dream, as a blast of light hit where she had been but a moment ago, her forcible and hasty exit ending the dream as the princess fled and Airy began to awaken...

Luna gave a yell of surprise as her eyes snapped open, involuntarily moving as she stumbled from her throne onto the hard floor.

"Luna! Are you alright?" A voice called out, causing Luna to turn her weary eyes towards her sister, Celestia, as she galloped up the stairs, stopping next to Luna with concern written all over her face. Calm began to spread through Luna, as her breathing calmed down and she stood up, no longer feeling weak or powerless as she had in the dream realm.

"Yes, dear sister; it was merely a... bad dream, that we encountered. Is it time to start the day?" She asked, as Celestia looked at her with concern, before nodding "Yes, I was about to come tell you, before I heard your yell. Are you sure you're alright, sister?" she asked, as she eyed Luna with concern in her eyes.

Luna huffed, as she looked away "We are fine, it was merely a dream we had not expected. A good day's rest will do me good" She said dismissively, before her horn glowed as the night sky disappeared below the horizon. Celestia said nothing, only watching her sister for a moment, before her own horn glowed and the sun replaced the moon in the sky.

Luna let out a sigh, before she began walking towards her quarters, only to stop as Celestia's hoof landed on her shoulder "Luna, if something is wrong, please tell me" She said, as she looked at her younger sister.

Luna stayed silent for a moment, before replying "As we said, it was merely a bad dream. Now, we believe you have some work to do, so we can finally go help Princess Amore... or do you not trust us?" She questioned her sister, who looked at her with wide eyes "Of course I trust you, you're my -" "Then good. Now, we need some sleep, the nightmares will not quell themselves tonight" Luna interrupted, as she walked away, leaving worried Celestia behind.

Luna would also fail to remember, that she hadn't talked with Princess Amore about the situation in the Crystal Empire, nor when they'd be arriving there.

And so, it would be her pride and ego, facing defeat at a mere memory of a great demon and the dreamer who turned against her, as well her choice to not consult in her sister, that would eventually lead Luna down a dark path as her dreams that day and years to come were filled with distant echoes of Ouroboros' laughter, coming from a mouth of her mirror image.

It would also bother her to remember the monster quote of the Celestial realm... a home of the race of gods named Celestials, a name far too similar to her own sister for her comfort.

And as the memories would fade in the coming years, it would be the words of a 'fairy', which she would become to consider a friend in those following years, which would eventually push her over the edge...

Airy groaned, as her weird dreams of Ouroboros and ponies ended, bringing her back to the waking world and leaving her unaware of her master's magic having been at work, a protective spell against unwanted intruders, which turned her dreams from harmless to lethal defenses... at least, lethal to all but Princess Luna, who managed to escape just in time.

A lesser magic user would have perished at the temple. Luckily for them, those who could travel dreams were extremely rare, for none other than Luna would face Airy's dreams, now or in the future.

Airy yawned, as the sunlight poured into her room, a start of a new day of work. Slowly standing up, Airy stretched her body, before she dressed up and took flight, landing on the string next to the door and ringing the bell.

A mare of green coat and light blue mane in armor opened the door "Hi, I’m Airy. You must be Shard, Glint told me about you yesterday. Could you help me a little and fill the washing bowl for me?" Airy pleasantly introduced herself, as the guard nodded her head and walked away, before returning a moment later with a maid, who walked in with a pitcher, before walking to the other table and filling the bowl with clean water.

With a thanks to the maid and the guard, Airy flew behind the curtain as the door closed, leaving her alone as she stripped down once more, before taking a soak in half-filled bowl of water.

It was so nice, to bathe in the lukewarm water, as she sun shined on her bare skin. She took her time cleaning and enjoying herself, but eventually she dried off and dressed up again, before drying her wings and flying off to ring the bell. As the guard, Shard, escorted her to dining hall for breakfast, the maid who had waited outside entered, beginning her (rather simple) task of cleaning the room.

"So, I don't mean to pry... but what did you two do?" Airy asked her guide, who stiffened, before pretending that nothing was wrong "What do you mean" Shard asked, her tone getting defensive "Come on, it's pretty clear that something happened, otherwise Thunder wouldn't have put you two to serve as maids; so please tell me, otherwise I'll have to ask Princess Amore" Airy replied, as Shard let out a sigh of defeat.

"Couple of us tried playing a prank on a fellow guard, but we accidentally dropped a cold bucket of water on a lieutenant as he came in for a surprise inspection" Shard explained, getting an "ooh" from Airy.

As they arrived at the dining hall, Shard knocked on the door, before opening it to let Airy inside. With a wave of thanks, Airy flew in, the door closing behind her as she flew to where Princess Amore, Radiant Hope and Sombra were already eating their breakfasts "Greetings, your highness, Radiant, Sombra. So, are we continuing the spell work today?" she asked, as the three greeted her back.

"Why yes; it would seem, that despite the early evening I gave them, my students were hard at work last night" Amore said with a smile. After glancing at the two, Airy could tell that the two were still sleepy, so while they slowly woke up, Airy decided to order a cup of water and a cherry; a perk of this form, as she required so little food while she stayed small.

Of course, if she transformed and stayed in her larger forms, she'd have to change her daily food size from a cherry to a pony sized plate... maybe even literally.

Airy was glad she didn't have such worries yet.

And so, the second day of work began, with the four of them joined by Glimmer and Thunder, with the six of them idly chatting as they began to eat their breakfasts of choice...

Celestia let out a sigh, as she finally sat down for the dinner. Between worrying about her sister and dealing with all the governmental duties associated with rebuilding entire towns destroyed during Tirek's rampage, Celestia couldn't help but wish she'd never see another villain again.

When the ponies had first accepted her and her sister as new rulers of Equestria due to their abilities to control the sun and the moon (as well as a moderate convincing from their former teacher, Star Swirl), it had taken so much time to learn proper governing on her part. Of course, Luna also did her duty, but it was mostly different from hers; Princess Luna's duties mostly consisted of managing the thestrals and healing the mind of their subjects from damages nightmares caused, while Celestia's duty was to manage the unicorns, the pegasi and the earth ponies.

Of course, it was only natural; As Celestia ruled during the day, most ponies came to her despite the fact that her sister also could have taken care of their problems; as such, the night court usually stood empty, with Luna dealing with dream realm while interrupted once in a while by thestrals.

Often weeks went by with nopony attending her court.

Maybe it was because of this, that her sister looked so worn down; dealing with nightmares of others took most of her time and magic, it left her with little rest, before she slept once more past the daily life. As the servant brought her food, Celestia idly began to wonder if she should start shifting more duties to night court, before dismissing those thoughts; it was clear, that Luna was already stressed enough as it is, dealing with repeated nightmares of Tirek.

And so, as Princess Celestia ate and began to idly read on reports of the unicorns and pegasi on their non-rebuilding related projects, she remained completely unaware of the seeds she planted; seeds of doubt about Luna's ability to reign, ones that would cause many misunderstandings between the sisters for years to come.

Yet as the time would come when such troubles began to heal, the actions and words left behind by one fairy would grow those seeds into a tree of villainy, one the world would fear a thousand years and strike grieve in Celestia's heart for millennia to come.

The one they would call... Nightmare Moon.

Author's Note

Now that the first five chapters are out, i'll be moving new chapter posts to be every 2 weeks or later, to pace myself.

You might have noticed the mention of Nightmare Moon, years before she would appear. This is not a coincidence. It's to let the audience know, that certain events would still come to be; A mare in the moon and lost empire among the things future elements would have to deal.

Yet as they dealt with these problems, the experience shall be different... for YOU, the reader, shall read on as the two genuinely good ponies eventually become among greatest of villains of Equestria, as well as the after effects of their changed origins.

Also yes, the realm is actually called "The Celestial realm" in bravely default, though it's the real world as shown to players. The Celestial in the story is YOU, the player, so don't over analyze it.

Also, fair mention at this point; Nothing from Bravely Default will cross over, other than the attempted copies of what Airy chooses to bring over. So no heroes, no villains, nothing; just things she makes.
