A/N: I recently discovered Acnologia's character and fell in love with him and I couldn't help but try to write a Acnologia/Lucy fanfiction. This is one of those scenes if Lucy were to encounter him in an unexpected place. I don't know if my attempt of writing it is successful but tell me what you think. Thanks.

Warning: The characters are ooc, slightly AU, adult content, adult language, and sexual situations. There are some ocs as well. The rating may change to M in the future.

Things to note: There are some changes in the Tartaros Arc event. One, Acnologia doesn't fight Igneel, in fact, Acnologia never appears when the demons fight against the Fairy Tail members. Two, Fairy Tail never disbands. And three, Lucy is the one to temporarily leave Fairy Tail to train her magic. Not Natsu and Happy.

Disclaimer: I don't own Fairy Tail.

Celestial Light

Chapter One

Lucy Heartfelia walked through the meadows by herself. The sun was shining brightly as her blond hair shimmered. She wore a simple white dress with white sandals. A belt with her keys wrapped around her waist. She didn't mind as some specks of dirt got between her toes as she dragged her feet along the grass. There was a point she left a patch of grassy area to walk through piles of dirt. She continued on, making a trail for anyone to travel if they would dare follow her. But no one did. She was by herself with a mission in mind. Lucy was going to train to call multiple spirits on the battlefield. She was tired of relying on Natsu Dragneel, Erza Scarlet and Gray Fullbuster for fighting her battles. They were growing tremendously in strength, while she remained weak. Or at least she thought she was weak until a discussion with her golden haired spirit, Loke, made her think otherwise.

Lucy was not weak. Her approach to fighting was different from her group members. She wasn't a physical fighter like Natsu, Erza or Gray. Her strength lie elsewhere. And Lucy was leaving Fairy Tail with the money she saved to train and find her position on Team Natsu. It was a promise she made to Loke and herself that she wouldn't return to Fairy Tail without finding her true strength in herself. Thus, Master Makarov was shocked when she knocked on his door one morning and announced her vacation from Fairy Tail. She requested him not to tell the other members of Fairy Tail for the fear that they would search for her. He agreed he would tell them when they asked for her, which would give her enough time to make her way to the train station and head for the farthest town away from Magnolia.

Besides, she was tired of being Natsu's shadow. She had to watch his fights from the sidelines and use supportive magic to assist him when she could. She wanted to be more helpful to her teammates, even if it meant to use her body as a shield. More than anything she wanted to be able to stand on her two feet without having Natsu, Erza or Gray fight alongside her.

"It's going to be a hard journey," Loke admonished her as he appeared next to her from the spirit world. "Most of the time you will experience pain. The training might be hard that-"

"That I will wish I was dead," she finished for him. "Then, bring it on. I refuse to be a bystander on the battlefield." Lucy raised her head and straightened her shoulders as she stopped in the middle of nowhere. She didn't care to scan the horizon or to glimpse how the sun rays angled down on Loke casting a saintly look. Her mind was made up as she sat down on the floor crossed legged, dirtying her white dress. She placed hands on her knees and she closed her eyes.

"Lucy, I don't know if this is a good idea. Maybe we should go somewhere closer to town," Loke said as he looked around him. He squatted down on the ground next to her. "You could try mediating somewhere where we're not alone. I feel uneasy with us being here."

"Then stay with me," she whispered. Loke almost missed her words.

"I won't be able to stay with you for long," he replied.

"It's okay if my magic is not sufficient to sustain you being in the earth world," Lucy finished for him.

Loke shook his head as he realized that his mistress was becoming her stubborn self. She was determined to train her body and mind. But if something terrible were to happen to her such as she was to collapse from exhaustion or lose herself in meditation, then there were no human beings to save her. Only he and Virgo, her other spirit, would be able to return her to society.

"Are you willing to sacrifice your life to become stronger?" he asked her with a frown.

Cracking one eye open, she peered at him from long blond lashes. Loke could see his reflection in her brown eye. "Yes."

Nodding his head, he sat down crossed legged next to her. He placed one hand on his knee while he raised his other hand to remove his sunglasses. Lucy opened her other eye as she tilted her head to gaze at him speculatively. "What are you doing?"

"I will sit by your side and help you train because it was I who talked you into doing this mission. Besides, if you're so determined to get stronger, I will help you."

Lucy pink lips curved into a huge smile. The smile took Loke's breath away that he momentarily forgot to breathe. For a moment, he wished he wasn't Lucy's spirit, but a regular human who could have a relationship with her. He knew that a relationship between human and spirit was impossible. He was going to live forever and she would eventually age and, sadly, die.

"Okay, how do we begin?" she questioned him excitedly. She clapped both hands together as she gave him a hopeful expression.

Lifting a hand to his chin, Loke glanced up at the sky as if searching for the answer to some long riddle. Hitting his fist in his hand, he looked at Lucy with brightness shining in his pale eyes. "What is your goal? What do you know about how you fight?"

Lucy paused while she thought about the answers to Loke's questions. "I want to be able to summon more than one spirit on the battle field as my goal. I know that I'm not a physical fighter like Natsu, Gajeel, Erza, Gray, Laxus or the others. I think I am better with fighting from the sidelines."

"That's where you're wrong," Loke said. "When we fought against Bickslow, you fought alongside me as a partner. You didn't cower on the sidelines. You withstood Gajeel's blows, you have the ability to unlock gates from different worlds. Lucy, you are something special."

His words caused Lucy to inhale a deep breath. She never saw herself as Loke described her. She always thought she was worthless next to the other fighters in Fairy Tail. But Loke made her sound strong and cool.

"If I were to think about how you fight, I would say you're more of a strategist. You are resourceful because you have more than one type of element to fight with." Loke put his hand under his chin as he stared at the meadow. "Aquarius is a water bearer and she can only be summoned in areas with water. Taurus is a strong minotaur who is a physical fighter. Cancer is crab spirit who attacks and cut hair with scissors. You can say he's a physical fighter too. Virgo is a maid, who digs tunnels and is able to fight opponents using her chains. Sagittarius is a man wearing horse who has great skill in archery. I have the ability to magic regulus for fights. Mostly I fight using my fists. Aries utilizes wool to relax her opponents and render them useless in fights. Scorpio uses sand magic by blasting great amounts of sand from his stinger. Capricorn is an expert with hand-to-hand combat and has enhanced strength. He's a physical fighter as well. Although, if we can get him to learn his ability to use his lost magic, he may be able to possess his opponents. Gemini can flawlessly transform into anyone, copying their abilities and knowing what the person thinks. Crux is a human cross that is an archive containing information on celestial mages and their spirits. Horologium is able to heal major skin deficiencies, can shield and endure rough climates. Lyra can sing beautiful songs based on emotions and requests. Plue is known to be quick on his feet and he dances fast. Pyxis is a compass that has the ability to tell directional references. Lastly, the spirit king, the strongest spirit, is known to fight using a blade. Am I missing anything?"

Lucy was gaping at the amount of information he shared about her spirits. Listening to how he described their abilities, Lucy formed different strategies to use them in battles in her mind. However, there was an important detail he missed. "I can't summon Aquarius anymore. I broke down her golden key to be able to summon the spirit king."

"You're right," Loke confirmed. "She was your mother's former spirit as well."

Lucy nodded sadly. Tears began to form in her eyes and Loke moved to embraced her, apologizing for reminding her of painful memories. When she was okay, she lightly pushed against his chest so he would pull back. He pulled away and ran a hand through his spiky hair. Lucy smiled as she wiped away the tears. "That's why I'm here. I'm going to train harder than before."

He nodded his head. "From the long list of your spirits, what do you realize about them?"

"I mostly have physical fighters," Lucy answered.

"And understanding that each and every one of them has a contract with you, you have to decide in which battle they can fight without disrupting the rules in their contract. This is hard for any celestial mage to do. Although you have fourteen spirits and have many options, choosing the right one becomes a challenge."

"Yes, it is," Lucy agreed.

"This is what makes you different from the other guild members in Fairy Tail. You have a wider base of attacks to use than them while most of them are limited to using one element. You can use more than one element on the field if given a chance. Therefore-"

"I have to rely on mental magic. If I have mental stamina to call more than one spirit on the battlefield, then they could combine their abilities to take out their foe," Lucy said excitedly. She bounced in joy from her seat while clapping her hands together.

Loke shook his head at her childish antics when he realized something important. "But if you want to build on mental magic, then you have to give up on being physically strong," he replied, cutting off her excitement.

Lucy stopped jumping at the thought of not being able to fight with others. "Are you saying that I won't be able to fight with you or the other spirits?"

"Unfortunately, yes. You can only have one or the other. You won't be able to master both abilities in a short amount of time. Most celestial mages are mentalists than physical fighters. Since they have the ability to summon spirits, their spirits are the ones to deal the damage," he answered truthfully.

Shifting closer to him meant that Lucy had to crawl on her hands and knees until her face was mere inches from his. His face flushed with color and he averted his attention to the clouds in the sky.

"Do you think I have it in me to be a fighter and answer me truthfully?" Lucy placed her soft hands on his face and gently moved his head until he was eye level with her.

"Honestly, it pains me to see someone hurting you," he said while staring into her brown eyes. "I think it's better if you summon your spirits to fight on your behalf."

"And what if my foe is able to get my keys or hurt me by dodging you?"

"These are weaknesses we are going to train so it won't happen." Lucy nodded her head as she pulled back, causing Loke to exhale a breath he didn't know he was holding.

"Okay, so where do we begin?" she asked him. Glancing down at her dress, he noticed the stains on it. Lifting his hand, he almost began brushing the dirt of the white seams when he realized how inappropriately close he was to touching her. Instead, he lifted his hand to drag along his hair while he laughed.

"Let's try meditating. Your level depends how you will be able to control your magic." Again, Lucy nodded her head. She sat down crossed leg and placed her hands on top of her knees. She closed her eyes and inhaled a deep breath. She called upon her magic from deep within her. In her stomach, she felt a tingling sensation that grew bigger and bigger. It felt like more butterflies were expanding in her stomach and were traveling to tips of her toes and fingers. She slowly exhaled a breath and the muscles in her body relaxed. Loke saw a bright light glowing from her core. As she immersed herself with meditation, he noticed the light got stronger until the beam could rival the sun. He took a deep breath as the light engulfed her form, casting a halo and making her look like the angel she was. Slowly and steadily, he got to his feet and stepped back from her and released his breath. He continued to marvel at the lovely sight that he never sensed someone else watching from the distance.

Leaving the forest to stroll through the meadow, the dragon shift shaper inhaled a deep breath into his lungs. He rarely let himself enjoy nature in his human form but today was one of those rare days he decided to bask in the sun as one. He exhaled a breath as his enhanced hearing could make out the high pitches from the birds soaring above him; he could feel and hear the soft whispers of the breeze and swaying whispers of the leaves and grass. Also, he heard the crunching sound of the grass beneath his feet. Flexibly rolling out his shoulders, he closed his eyes to feel the warmth of the sun against his face. A slow smile spread along his lips until he felt something strange against his senses.

Who would dare enter his territory without his permission? He growled low in his throat as his peaceful moment came to an abrupt halt. Crouching, he opened his five senses to intruders who dared to enter his lair. Two magical auras hit him. So, there were human vermin on his territory. They could use magic unlike most human abominations who lived to eat, drink and breathe and destroy everything. Parasites like them gave dragons a bad name. They believed dragons to be monsters because they destroyed their homes and burned crops. The actual truth was humans were increasing like a plague and they were the reason that dragons scattered and hid from the earth world. He was not one those idiots who wanted peace with the pests. He viewed them as insects who need to be crushed before they expanded their territory in the world.

All humans were selfish, greedy, insolent, and arrogant bastards. He grinned widely, showing sharp white teeth as he recalled the day he played with a small group of humans on Tenrou Island. He blocked their escape route, heard their cries of despair as he lashed out with his wings on their puny bodies. Four of them were suppose to be dragon slayers and he easily took them out without battling an eyelash. They combined different attacks and all he felt were feathers hitting his solid scales. He laughed aloud as he used his dragon roar to erase them permanently from the world. Stupid humans had no choice but to hold their hands together as if the little action was going to save their lives. He shook his head. Maybe he ought to give the simpletons the same treatment.

The dragon shape shifter, known as Acnologia, walked quietly toward the two auras. He could hear one of them had a melodious voice. If he didn't know any better, he might have become entranced with the tone. The melodic voice lifted to a point it sounded like bells, than lowered to whispers and he found himself moving quietly and quickly toward the voice. Another voice was rougher and sounded deeper. He growled at the distasteful voice, picking it as his first victim to destroy. He smiled darkly as he was gathering his magical energy around his lithe form. But as he moved closer to the two auras, two things made him stop in his tracks. One, the auras differed greatly. He could sense one was a human while the other one was not physically part of the earth world. He frowned as he discerned both presences. One aura almost floored him as he never felt such pure energy radiating through his lands. It seemed so calm, peaceful and angelic. Acnologia never knew a human could have such a wonderful presence. Raising his hand to his head, he shook it until his long pale hair brushed against his face. Narrowing his eyes, he zoomed his magical energy on the other one and frowned. The other presence was a spirit from a different world. Closing his eyes, he could hear their voices. One voice sounded feminine while the other one sounded masculine. The one that hypnotized him was the feminine voice. Frowning, he wondered when was the last time he was interested in a female. He couldn't remember since he thought most of the dragons and insects were under him.

Deciding to shield his magic from the two invaders, he observed them using his draconic senses. The next sense caused him to clench his fists. The female smelled wonderful. It reminded him of vanilla laced with lavender. He closed his eyes to remember the last time he smelled something so delicious. Would she taste as good as she smells? He wondered to himself and almost slapped himself for having such disturbed thoughts about a petty human.

The other presence backed away from the angelic one, and Acnologia felt how his muscles stiffened. The feminine magical aura raised to a high level he never felt before from any human. She had high levels of magic in her. If she were to be a tool used as a magical source, the one feeding from her energy can feed from it in days and that was unusual task to do from a human.

Out of curiosity, he moved closer to inspect the two forms. Straining his eyes, he could see them from fifty feet away whereas they won't spot him with their dull senses. He smiled evilly as he realized he could spiral some his magic at them and destroy them in an instant. But what fun would there be in killing them instantly? He preferred to play with his prey before going in for the final kill like he did with the insects on Tenrou Island seven years ago.

His smile turned into a wider grin as he lowered himself on one knee and continued to inspect the two figures in his terrain. He would let them live for today. Maybe he could observe them, learn a one thing or two before killing them. Liking the idea, he shielded his presence and settled himself comfortably on the grass for the long wait.

The pain was excruciating as Lucy felt her muscles stiffening in her body. She had a bad feeling that when her training was over for the day, she won't be able to move a muscle and she would have to rely on Virgo's assistance with making a campsite. Her loyal spirit would stay the whole night to make sure she was safe. And Lucy hated to have her spirits worry about her. Her goal for training was to make her stronger so she could stand on equal footing with her spirits, even if it meant that she would be a magical source for them. The meditating was becoming unbearable. Her magical aura felt like it was splitting her body in half. Her arms and legs were cramped as she tried to endure summoning her magic for the past eight hours. Sweat was dripping down her face and body. Luckily, she wore a different outfit provided to her by Virgo from the celestial world. Lately, Virgo was the one who took care of her personal needs while Loke and Capricorn spent time training her.

"You can stop meditating now, my lady," Capricorn commanded. Letting out a breath, she ungracefully collapsed on the ground. Her body felt like dead weights as she was lying on her face. Loke popped out from the spiritual world to check on her. He knelt next to her as he applied gentle pressure on her arms before shifting her to lie on her back. She moaned in the back of her throat. Her breathing came out in pants. Loke brushed some of the blond locks away from her sweaty face.

"She's been training for the past four days. Will she be alright?" he asked the other spirit who was watching her exhausted state.

"Yes," Capricorn answered. "She's getting better with sustaining her magic at a certain level for a long period of time. If she were to call on two spirits, let's say Horologium and Gemini for a battle, she would have sufficient amount of magical energy to keep them on the field for more than an hour."

"What if they were hit with a deadly combo from their enemy?" Loke questioned as he furrowed his eyebrows. He positioned Lucy's hands to her sides to make her comfortable.

"They won't disappear from one blow, if that's the answer you're looking for. They should be able to withstand multiple hits because our lady's magic will sustain them and us."

"And how long do you think it will take her to be able to summon many of us on the battlefield?"

"From what I observe in her training so far, she has vastly improved with gathering magical energy and being able to hold it in her core for long periods of time. If she continues with this vigorous training, she will be capable to summon all of us at once for no more than a half-an-hour."

Loke breathed in deeply from Capricorn's estimation. He gazed at his mistress with awe. "Is that even possible?"

"From her tenacity, determination and love for us, anything is possible. I have never seen another celestial mage with her abilities," Capricorn replied as he kneeled before his mistress. "But she is a human and she has needs. We need to take better care of her because if she continues this type of training, she may die."

"Yes," Loke agreed. "She has put too much stress on her body."

Another golden flash appeared, signifying to the other spirits of Virgo's arrival. The materials to make a camp was lying next to her. Dressed in her usual garments, which consisted of a maid's uniform and chains dangling from her wrists, she approached her mistress with a hot bowl of soup and a spoon in her hands. Briefly, she looked at Capricorn and Loke and nodded her head at them. The quiet exchange between them notified to the male spirits that they were to setup the campsite. Loke moved to make a tent while Capricorn shifted to make a fire from the flints and wood Virgo was able to provide. When both of them were finished, Virgo shooed the men. Virgo raised Lucy's head into her lap and spoon fed her the soup. When Lucy finished her soup, Virgo gently placed Lucy's head back on the ground. She heard her mistress' moans from pain and dutifully, she placed the empty bowl on the side.

"My princess, I need to you summon Aries to help me change your clothes and to provide you with soft wool to sleep on tonight," she said. She leaned down and gently took Lucy's keys. She located Aries and held the key in Lucy's hand. Quietly, Lucy said the chant and Aries popped next to them.

The pink haired girl stared at her mistress and gasped at her. "I'm sorry," she muttered before bowing to both of them.

"It's not your fault. Our mistress wants to get stronger for us," Virgo reassured the gentle spirit, which was something she didn't do for just anyone. Most of the time she was stoic but witnessing how their wonderful mistress wanted to become stronger on their behalf, Virgo's compassionate side began to reveal itself. Also, Aries always blamed herself when she didn't do anything and seeing their mistress in such a helpless state worried Aries. Aries believed she wasn't strong enough to protect her mistress and the training was due to her inabilities to perform successfully on the battlefield.

Aries bowed her head in shame as she heard whimpers coming from her mistress. "I'm sorry for not being more helpful."

Virgo put a hand on Aries shoulder and shook her head. "It's not yours or anyone's fault. And you are being helpful to her. Our princess knows she has our support and that all she needs to complete her training."

Aries nodded her head at Virgo's comforting words. "Now, let's get her dressed for bed. She has another long day ahead of her." Aries followed Virgo's lead in preparing Lucy to sleep comfortably in the tent. When they were finished, Virgo gave Aries the permission to slip back into the celestial world but Aries shook her head.

"I'm sorry but I want to stay with you to help protect our princess," Aries replied with a little determination. She raised her head in the air as she took her seat next to the maid spirit.

Virgo's lips twisted into one of her rare smiles. "Okay. She will really appreciate it." Little did they know that someone was continuously observing them and waiting for the right moment to strike at their beloved mistress.

Three days later Lucy found herself huffing and puffing on the floor. She could barely stand on her two legs, far less walk to the stream next to them. Loke had them transfer their campsite to a place near where there was running water. Getting water was easier for Lucy and she could enjoy her baths in peace but the water was constantly cold and Lucy really missed enjoying hot baths. She wanted to quit the mission so she could return home and enjoy the luxuries in her apartment but she couldn't give up on herself or her spirits. The past week, Lucy felt like she made a closer bond with her spirits. They were supporting her and their friendships were more meaningful. They relied on her as she relied on them. They were a team and her family when she didn't have the Fairy Tail members with her.

And this training made her realize how wrong she was about not having a family before Fairy Tail. She always did have one. The first few spirits she had with her were her family. She considered them to be a part of her when she had to struggle to live alone. They fought at her side, kept her company when she was alone and gave her hope. Her spirits meant the world to her.

With a new resolve, Lucy forced herself to get up from the dirty ground. Capricorn watched with amazement as his mistress hands clenched into fists on the floor. She banged one of them against the grass as he heard her swore in a unladylike manner. "Damn! I can do this!" With a grunt, she slowly but surely got up while giving a little yell. And miraculously, a light from her meditation began to glow from her stomach area. He stepped back as he watched with astonishment how she stretched to her full height. Raising her hands to the air, the white light got brighter until it almost blinded him. He shielded his eyes with his hands to prevent himself from getting blind, although he was already wearing his sunglasses.

"What the hell is going on?" Loke asked as he popped next to him.

"I don't know. I have never seen this type of power coming from a celestial mage," he replied.

"Can you feel her magical aura? It's overflowing with massive energy." The air radiated with waves. Loke glanced at his feet and he could see how the grass was dancing from the powerful waves. His eyes widened as specks of dirt began to float around Lucy. He retreated and shifted his shades. He was glad that his sunglasses protected his eyes from the bright light. Diverting his attention next to him, he saw Capricorn move his hands away from his eyes.

"Do you think I should have her summon Cancer?"

"Yes," Loke answered.

"But if I do, I want her to be able to mentally summon him instead of verbally. This way if she's in a fight, she will be able to mentally call on any spirit without having to notify her opponent who it is. She will have the advantage. Also, as long as her keys are on her, she will be able to summon any of us."

Loke nodded his head. He watched as Capricorn stepped toward the young woman radiating strong magical waves in the vicinity. She looked exquisite with her blond flowing around her like a halo. Her dress was blowing around her, showing her curvaceous figure. He shook his head to deviate his thoughts from turning impure.

"My lady, try to summon Cancer in your mind. No matter what you do, don't touch his key or don't say his name," he said out loud so she could hear him.

Loke saw her frown. With her hands still raised in the air, he felt more than saw how her magical aura stopped increasing and stayed on a steady level. He realized she was concentrating. The waves soared through the area and around his and Capricorn's form, hovering around them before disappearing. Capricorn folded his arms across his broad chest as he grinned. All of a sudden, a pulse came from her and with a flash of light, Cancer was standing next to her. His scissors waiting in the air; his offensive stance screaming for a fight. Capricorn took a step forward and dashed at Cancer. Both of them began their fight.

Unknown to the spirits or their mistress, the dragon shift shaper stood from a distance observing the celestial mage grow more powerful in her training. All the years he wandered the earth, he never felt anything like her power. Even standing fifty feet from her, he could feel the immense strength of her magical aura. Day by day, he watched her grow in power. From the first day when she could only summon one spirit to stay with her for a short amount of time and than seeing her interact with three spirits a week later was a feat to accomplish. Two of her spirits, one whom looked awkwardly like a goat man in a black suit, were training with her using their own magical power. The other crab like figure with shaggy hair and scissor hands was summoned using her magic. But the pulse he felt made his muscles tightened. It stretched as far as he was standing, probably alerting her of his presence. Then, two of her spirits clashed. The goat man's fist collided with the crab man's scissors and an intense wave clashed right into his form, almost making him step back. It was astounding that the blond girl didn't move. Instead, she stayed in one place, unaffected by the two spirits' duel. The blond man he disliked, had to cross his arms over his face. His posture was in a defensive position to protect him from a deadly impact. Acnologia smiled wickedly as he noticed the drag marks on the ground by the blond man. The two spirits caused it from their sudden clash. Although, he wanted to kill the blond haired girl a week ago, he couldn't help but be impressed with her improvement. She was proving not to be a force to reckon with. And he was curious about her nature. So far from what he knew about humans, she was defying his logics. She was an enigma. Begrudgingly, he found himself wanting to know more about the golden haired girl who can summon spirits from another world.
