Author's Note: I couldn't get this idea and OC design out of my head, so here I am writing another fanfiction for all you Fairy Tail fans. XD (That is what happens when I should think about homework and study…. My brain loves to do this to me when I need to concentrate on something else… xD) Nevertheless, I hope you will enjoy this story and like my OC Celeste! :3 Have fun reading~

Prologue

In the year x774, a fecerious demon from the books of Zeref, known as Deliora, rampages through a small city in the north. It wrecked havoc on his way, destroyed buildings and killed hundreds of people and families, until only debris was left of the once so peaceful town. Only then, Deliora was satisfied and continued on his way, leaving only destruction behind.

A fearless ice wizard and her student arrived by the scene just as Deliora was growing smaller in the distance.

Ur looked around the destruction and tsked. "Once more Deliora only left chaos and death behind in his path… How much longer will this have to continue? How much longer do we have to bear with this rampaging demon?!"

Meanwhile, Lyon looked around the debris, searching for survivors. Suddenly, he heard a silent groan and spotted a boy his age, half buried under a piece of debris. "Ur! Over here!" He shouted for his sensei and rushed to the boy's side. "Oi, are you alive?!"

Ur quickly appeared next to him and lifted the debris from the boys leg. "A survivor?!"

The boy with dark hair slowly opened his eyes. "Deliora…" Gray mumbled as he stemmed himself up and stared fearfully at the demon who was slowly vanishing in the horizon.

"Hey. Are you alright?" Ur touched the shoulder of the boy carefully, as it seemed to be a miracle to her that the little guy was able to survive such destruction.

And just as if Ur was able to break Gray out of his stupor, the boy bolted up and looked frantically around. "Cel!" He called loudly in panic while looking around.

"Cel? Who's that?" Lyon asked Gray in confusion while Ur stood up and looked at the panicking Gray sadly.

"Celeste! M-My imouto! Where is she?!" He shouted at them, not wanting to believe that something happened to her after they just lost their parents a few hours ago.

Ur looked sadly down to Gray. "I'm sorry… but you're the only one we found alive."

Gray's eyes widened at that in disbelief and fear. "N-No! That can't be! S-She was just right next to me!" He screamed at her before turning around and running towards the debris, where he knew his little sister was before he blacked out. "CEL! CEL!" Gray shouted desperately at the verge of tears as he remembered his sister's brave face after seeing their parents die… No, she couldn't have died! There was just no way!

Ur just looked utterly sadly at Gray as he started to try and dig through the mountain of debris, all the while screaming his sister's name. Lyon just sighed.

"C-Cel!" Gray screamed again and dug his fingers into the debris, tears streaming down his face. Just then he spotted something familiar looking and lifted a little piece of debris off it. His eyes widened in horror as it was a little, torn off and bloodied piece of the yellow dress with sunflower pattern his sister had worn… as well as a little arm peeking out from the rest of the debris. "N-No….! Celeste… Y-You can't be…. You can't… Imouto…" Gray choked on air as he collapsed next to what he found that belonged to his little sister… Had belonged to his little sister. "NOOOOO!" The boy screamed before breaking out in tears. It was a sound filled with unbelievable sorrow, sadness and horror, nothing someone his age should be capable of making.

"…I'm sorry." Ur apologized sadly to the boy as she knelt down behind him and laid a hand on his shoulder in support. "But I believe there's nothing more we can do for her…"

Lyon looked sympathically at Gray before staring sadly down at his feet, knowing exactly how he felt, being a survivor of Deliora's destruction himself.

Gray just gritted his teeth while tears streamed down his face as he softly took the torn off piece of the dress in his hands. "…He will pay! DELIORA WILL PAY FOR THIS!" He shouted in rage and thrist for revenge.

Ur frowned sadly at that before she sighed and stood up, already having decided on taking the boy in as her student. No matter how much darkness now surrounds him, she may be able to help him back to the path of light. That's what she's living for and that's what she will fight for.

Meanwhile, in an unknown place…

"W-Where am I…?" A little, seven year old girl slowly opened her brilliant green eyes. She looked around but couldn't move. The dark haired girl's gaze shifted around in confusion. She was surrounded by bright golden light and seemed to float in a sphere of some sorts. "W-What's going on?!" Celeste narrowed her eyes as she tried to figure out…where she was…and what happened…

Green eyes widened as she finally was able to get through the hazyness of her mind and recalled what happened: Deliora attacked their town and destroyed everything in his path… Her parents then hid her and her older brother just before both got killed… She remembered how she and her brother fled out of their collapsing house… How they both tried to get away from the demon before she suddenly stumbled and tripped… How Gray stopped to help her getting back up…. And that's when she recalled what happend then… How she got a bad feeling and looked up just to see a huge piece of debris flying their way and then… how everything seemed to slow down… How time itself slowed down as she pushed her older brother as far out of the way as she could without even thinking… And then, how she was hit by the giant piece of debris and crushed by its sheer weight…

Celeste gasped at that and shuddered before she was slowly able to lift up her arms as her frozen state seemed to wear off. "…I'm dead…..?" She whispered into the bright, seemingly endless space of light while staring at her hands in disbelief and confusion, her child mind not being able to wrap around that fact…. Nor the fact that she still could think…and feel her fingers…

"Fear not, child…" Suddenly, a loud, deep, rumbling, but warm voice sounded through the sphere.

"Huh?!" Celeste got out and looked around the sphere as she slowly sat up…not being able to make out from where the voice came from as it sounded like it was coming from all around her.

"You were right, Celeste Fullbuster. You indeed died." The voice told her.

Little Celeste furrowed her brows before nodding slowly in understanding. "…I see. But what is about Nii-san? …Did Gray also …" She asked the voice desperately, hoping her brother was able to survive.

The voice was silent for a while, as if baffled to how this child was able to get over her death this quickly and especially accept the fact. That is something he almost never sees, only by special and strong willed humans. But that she still worries over others after everything that happened was truly something special. "…Gray Fullbuster is still alive." The voice told her after being silent for a couple of minutes…well…if there would exist time in a place like this.

"Really?! I'm so glad." Celeste smiled happily, being able to accept her fate because she could save her brother after all, so there's was nothing to regret on her part.

The heavenly voice fell silent at that for a moment again. "You have no regrets, Celeste Fullbuster. But fate was not supposed to be that way. A lot of important matters were planned for your future. You're something special, child."

Celeste blinked at that. "What do you mean, mister… sir…? Ehm… Excuse me, but I don't think I got your name…" She said in childish wonder.

"Child… That is not of importance at the moment. Do you know where you are?" The voice grumbled at her.

The seven year old girl looked around the bright light sphere and chewed on her lip thoughtfully. "In the afterlife maybe…?"

"Not exactly. You're in a timeless space in between the world of the living and the world of the death." The voice explained to her. "But there's a reason you're here and not in the afterlife together with your parents."

"Mommy and Daddy are there?" Celeste couldn't help but interrupt him as sadness flooded through her as she remembered the death of her parents.

"Quiet, mortal. Let me explain first, and then you can ask questions as much as you want."

Celeste bit on her lip at that and nodded quickly, not wanting to anger whoever was taking the time to talk to her.

"As I already mentioned, you're something special because it wasn't planned for you to die today. In fact, both you and your brother Gray should have survived the attack. But something… happened that changed the events… for the worse. That's why I am left with only one option to fix this issue or the mortal world will be doomed. This option is you, Celeste Fullbuster."

Celeste bit on her lip at that to not interrupt the explanation of the being that spoke to her. Her thoughts raced as her child mind tried to understand the things that were being said. Luckily, she always was smarter than others her age and so was able to understand the majority.

"Celeste Fullbuster, you were chosen to deal with the… problems in the mortal world. You were chosen to fight for the right things and hinder everything from collapsing. That means, as much as it usually is against my profanities, you can be revived and send back to the human realm to live with Gray Fullbuster, but only if you swear on your brother's life that you will also live to fulfill the tasks given to you…for the sake of everybody."

Celeste just gaped in disbelief at what the voice said. "I…" She opened her mouth to say somethig, only to close it again as no word was able to come out. Was this really happening? Could she really trust this voice? …Was there really a chance for her to live with her brother…but for what price? Celeste chewed on her lip as all these questions ran through her head, but the more she thought about it… The more it was getting clear to the seven year old. She had nothing to lose anymore, she already had died. And now for someone to offer her something like this… that she could see her brother again, who was already hit so hard by their parents death, not to mention hers as well now…. To see her brother again and support him, she would risk it all. And if it was for the greater good, what was there to lose?

"…I accept your conditions, sir." She told the voice in true determination, not knowing what these tasks were yet, but having the feeling already that she would do the world a favor if she does this.

"…Good choice, child. Indeed a wise decision from someone your age. Just a warning before I ask you again: The world's fate will lay on your shoulders and you will have very hard times and fights before even being able to get near your brother. Do you still want to accept, even when knowing that you will have to go through a lot for that?"

Celeste just nodded, not considering declining that offer, even regarding the danger awaiting her."Yes, if that is what it takes, I will do it."

The voice fell silent for a moment at that. "You're really someone brave for your age, Celeste Fullbuster. I will tell you everything then. But before that child, now that I'm able to trust you enough, let me tell you one important thing..."

Celeste blinked at that and couldn't help but feel childish curiousity rising up in her. "What is it?"

"Celeste Fullbuster, because you will fight for the greater good and as a thank you for your upcoming duty, you're worthy enough to know my name. I am known as Ankhseram to your mortals, the overlooker of all!"

"…W-What?!" Celeste eyes widened at that in utter surprise, she had read about the name Ankhseram in the books of ancient history before, that her mom loved to read just as much as she does. "…Y-You're kami-sama?!"

So, that was the Prologue! :3 I hope you are interested in reading more of this story as well as getting to know more about Celeste herself. I would love to read your thoughts on this, so feel free to comment! :)
