Loki's Sister

Pairing: Loki and Sister!reader

The library. That's where he would rather be currently. Not at some, rowdy party bursting with drunkards. But then again it was his father's birthday, and as a prince of Asgard, he was expected to be present at the royal celebration.

The raven-haired prince cast a shallow glance at the mead table where his merry brother seemed to be busy with an assortment of women. Thor had always been the party animal of the two boys. Loki was always more reserved and quiet, preferring the company of books rather than that of people. The younger prince sighed and returned his gaze to the floor.

He was currently standing on the left side of his Father's throne, not paying attention to the conversation His father, Odin, was holding with two noble looking gentlemen. To his left he caught sight of his mother, Frigga, laughing and chatting with three other women. She looked beautiful in her golden robe with a sapphire and ruby trim. Loki smiled fondly at her before resuming his staring contest with the marble floors.

There his thoughts began to wander of all that had happened the last few weeks. So many things had occurred it caused Loki's head to spin slightly. Thor had been banished for foolishness but had returned when found "worthy" as his Father called him. Odin had suffered a fatal heart attack but, as it seemed, was on the mend. The Bifrost had been destroyed by Thor to save the disheveling race of Frost Giants.

Loki sighed as he remembered his own treachery, how he placed his father in danger just to earn a name for himself. How he had allowed Asgard's worst enemies into the kingdom in order to keep his brother off the throne. How he had sent the destroyer to kill his brother and his friends. These memories of guilt swirled inside his head, and though his family had forgiven him, he knew Asgard never will.

Despite all these groundbreaking affairs, nothing shook him as much as the discovery of his race. His father had told him, right before his heart attack, that he, Loki Odinson, was not of Asgard at all but instead a foul frost giant from Jotenheim. Even now, the revelation of his heritage shocked Loki. He could never grasp that he was the son of Laufey, the very Frost giant King that was in his dungeons this very moment. Loki shook his head as if it would dislodge all the memories and the cold truth from his reality but, alas, memory is both a gift and a curse; one that can never be erased.

This startling revelation only gave Asgard another reason to both fear and hate Loki. However, his parents had strictly advised the kingdom against any attitude of hostility towards their younger son. It was humiliating, to have his parents guard him from bullies as if he were a child, but he was grateful to having been accepted and ever so loved by them, despite his differences.

Loki was jolted out of his thought by the booming voice of his father.

"Bring forth the prisoners!" Odin ordered, "The time that Asgard has so fervently desired has arrived!"

And so it had. The time of the execution of Laufey and his comrades. Men and women jostled each other in a rush to leave the great hall and flood into the courtyard for the best seats. It made Loki sick to his stomach to think that one could rejoice at the death of another. Nevertheless, he trailed his father and mother as they made their way to the courtyard.

0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0

Once there, he could see Laufey and his five companions standing before the large guillotines about to be decapitated. The executioners dragged a filthy looking frost giant toward the blade and placed him under it. The beast continued to snarl and wriggle until the blade fell and he was left completely still. The crowd roared as his head rolled onto the ground leaving a trail of dark purple blood. Loki winced as the process was repeated for three more frost giants.

Finally, all that was left was Laufey and a small frame cowering behind him. The poor thing was dragged toward the guillotine. Only when the guards dragged the frost giant from behind Laufey could Loki see that it was a young girl. She had long raven black hair and piercing blue eyes much like his own. She looked about his age and was slightly shorter than him. He looked upon her with pity. She was obviously terrified as she kept screaming in a tongue he could not decipher. She looked up at Loki her eyes fearful then angry then fearful once more. He could practically hear her pleading to him to save her. He felt a heavy cloud settle in his chest for she was bound to die.

Seeing his resolution, she left his eyes and returned them to Laufey. What she did then made Loki's heart stop. She screamed a single word.

"Father!"

Loki could feel thoughts swarming his mind as she continued screaming as she was dragged toward her death. Father? Laufey was that girl's father? But that would mean she was his… dear god could it be true?

The young frost giant screamed once more "Father please save me!"

Laufey looked at her as an evil grin spread along his features. He would not save her. He would let her die. Loki was not sure what force came over him, but he would not fight it. He suddenly felt an overwhelming deluge of emotion surge through his veins. He would not let her die.

At the top of his lungs he yelled "Stop!"

Time seemed to freeze as Loki jumped from the royal stands towards the executioner. He could hear his mother calling him back and the crowd's exclaims of surprise. He, however, did not stop. He ran up to the girl who was now looking at him in fear, but in her eyes shown a tiny glimmer of hope. When he reached the executioner, he found himself at a loss for words. He was unsure of what to say or do. How could he have been such a fool? He stood there awkward and speechless until his brother came to his rescue.

"Brother what is this madness?!"

Okay, not exactly a rescue.

Loki turned to face him. "She is the daughter of Laufey" Loki said his voice quivering.

"So?" said Thor "All the more reason for her to be killed!"

"No!" yelled Loki, furious at his brother's ignorance, "She is... m-my… sister" Loki finished.

Thor's eyes widened as the pieces clicked. By this time, Frigga and Odin had caught up to their sons. Frigga gazed upon the young frost giant, pity and motherly sorrow in her eyes. Odin, however, clenched his jaw. Loki could see anger in his eyes.

"Please" said Loki, unsure why he felt such a sudden affection for a complete stranger, "spare her life."

Odin's face relaxed Loki saw love in his eyes but also uncertainty. The king shifted his gaze to the young frost giant. She looked up at him for a split second but quickly lowered her eyes, staring at her shackles. In that quick glance, Odin saw her innocence and vulnerability; the same look he saw all those years in a temple in Jotenheim in the eyes of a small baby. Odin returned his gaze to Loki who stared back at him, imploring silently. Finally, Odin cleared his throat, getting the attention of the confused crowd.

"The execution is over! Return home!" Upon hearing the disheveled groans of disappointment from his subjects Odin added "but return this evening for a grand birthday feast!" Cheers erupted, and the crowd quickly started to disperse.

Odin turned to a guard "give her a bath and some proper clothes then bring her to me in the throne room. And you!" he said pointing to another guard "Make sure you return Laufey to his cell"

Loki bent over to help the girl up. She looked at him with confusion. Loki stared back. He studied her features and only now he realized how similar they were to his own. She looked as if she was about to ask something but before she could open her mouth she was hurried out of the courtyard by the guard.

Loki stared after her, hardly believing that fate had brought to him a true blood sibling.

0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o0o

He twirled his thumbs anxiously as he stood by his mother's side. It had been an hour since the affairs in the courtyard. Loki had tried earlier to visit the frost giant in her quarters but the guard had not let him in, saying it was "too much of a risk." Loki doubted that the young girl could have done anything to hurt him, nevertheless he did not press the matter.

Now, he and his family (excluding Thor, who was off god knows where) were waiting in the throne room to meet and question their unexpected guest or as it seemed, family member.

Loki remembered her fearful blue eyes from the courtyard as she was dragged to her seemingly inevitable death. He wondered if that would have been his fate if Odin had not picked him up that day. Loki turned his thoughts to the frost giant. Guards had tortured and interrogated Laufey and had found that she was indeed his daughter, the second of two twins. Twins! Loki thought incredulously. Not only a sister, but a twin sister at that! It was almost impossible to believe. Sure, Thor was an… adequate brother, one that he loved well enough, but he was a sibling by acceptance. Now, Loki had the privilege of having a sibling by blood and heritage, one so close that even from the beginning they were together in the womb.

This once unknown connection to the young girl stirred within Loki a swell of love and determination. He indeed believed that he must be the protector of his beloved sister, her sturdy rock, her pillar to lean on. And it was these thoughts that stirred up his insecurities. Would he be able to do these things for her? Would he be able to hold her trust? Will she put her trust in him despite all his treachery and trickery?

Will he be ready?

As if on cue, the doors of the hall swung open and in walked the girl he had been pondering about for the past hour. She still looked weak and, despite her blue skin, pale. But her hair had been brushed, her face had been washed, and her clothes had been changed. She now wore a simple dress, dark green silk with a high waistband. The sleeves were long and the skirt brushed past her ankles. Though the dress was rather plain, Loki had to admit that she looked stunning in it. Her wavy raven-hair hung loose and dangled past her hips. She still wore her shackles.

The guards pushed and pulled her roughly towards the throne. Loki clenched his jaws and fist, willing himself not to rage at them for treating her like a criminal. Upon reaching the foot of the stairs leading to the throne she was roughly forced to her knees. She lowered her head not meeting anyone's gaze.

Odin stood and slowly began descending the stairs. Loki could see her shaking as she waited. Once Odin reached her, he bent over to meet her eye. She would not look at him. He gently took her chin in his hand and lifted her eyes to meet his. What he saw hurt his heart. Here were eyes that were red from crying. He could see her carrying a flood of emotions; sorrow, fear, anger, hate, regret, guilt.

Suddenly she felt herself begin to change. Loki gasped slightly as the girl began to transform. Her blue skin blended into a peachy pale. Her features became smaller and her frame became even thinner. Within seconds, Odin's touch had transformed her into a human shape. Odin smiled fondly and gently let go of her chin. He took each of her hands in his and helped her stand. Doing so she caught sight of her now peach colored hands. Loki half expected her to recoil in fear and the other half attack in anger, but instead she stared her hands neither fearful nor furious, but rather intrigued.

"What is your name child" Odin finally spoke.

She looked up slowly and answered quietly "(Y/N), daughter of Laufey."

"Do you have a mother (Y/N)?" Odin asked.

"If I did, I no longer know her." (Y/N) answered.

"And what of a brother?" Odin pressed gently.

At this Y/N paused, an unknown emotion clouding her eyes. "Some say I had one at one point. He looked just like me, eyes, hair, and everything. But he disappeared soon after the fall of Jotenheim." Her voice was emotion-less but Loki felt his heart stop. There was no doubt now. He started forward, but his mother held him back.

"Why would Laufey bring you into Asgard?" boomed one of the guards pointing his spear at her, startling Loki. Odin looked at him with annoyance but (Y/N) barely flinched as she faced him.

"My father wanted his best warriors to join him on the mission to overthrow Asgard" she said, her face and voice darkening.

"And do you still follow that mission?" questioned Frigga.

(Y/N) immediately softened when she faced the queen "No ma'am, I never did."

Loki looked up surprised. What did that mean?

"I was supposed to kill the guards in the king's chambers" she explained, as if sensing his confusion "But I could not, for it is wrong to attack the Allfather; and for that, my father has not forgiven me." "

You- you betrayed your father?" Loki asked, his voice barely above a whisper.

For the first time, (Y/N) looked into his eyes and guiltily added "and my people."

Loki wanted to tell her how he could relate. He wanted to tell her that he too betrayed those he loved trying to what he thought was best and, in the end, placed them all in danger.

"Never mind your father or your people" Odin interrupted. "You are one of us now" he motioned Loki to come forward.

The god of mischief obliged and stood by his father's side. "This is the boy you heard rumors of. This is Loki Odinson" Odin paused...

"Your twin brother."

(Y/N) stared as if Loki had sprouted horns, her mind not fathoming the words spoken to her. She remained speechless not daring to believe the obscure truth Odin presented.

"Many years ago" Odin continued "In a temple in Jotenheim, I found a baby boy left to die. He was an innocent child, born of the blood of a monster. I could not leave him" as Odin spoke his hand went up to Loki's shoulder. Loki could see an inner war was being waged within the young girl before him as she tried to grasp the newly bestowed information.

"Well" she finally stated uncertainly "That explains why we look so similar" she smirked slightly earning a grin from Loki and a full-bellied laugh from Odin. Loki wanted to walk up to her, tell her he was there for her, hold her in his arms and be the brother for her that he never was. But as usual, Thor interrupted the moment by bursting through the door a large smile on his face.

"They are here!" he announced. "the people of Asgard have returned for Your birthday feast father!" Odin sighed and quickly turned to the guards. "Undo her shackles" he commanded. "But sire-" "Obey your king! Take off her shackles now!" obediently but resentfully the guard undid (Y/N)'s shackles. Gratefully (Y/N) rubbed her sore wrists.

It was a matter of seconds before people began to enter. Odin ordered (Y/N) to stand by Loki near the stairs while Frigga and himself engaged with the guests. The two twins stood side by side: not touching, not talking, not moving, and Loki could swear he was not breathing. Tension sat like a corpulent cloud over and between the two. The music blared. The dancers swayed. The party continued. Loki decided to finally say something.

"Are you enjoying the party?" They both said at the same time.

At first they stared, but then began to chuckle slightly. Loki tried again "Do you like parties?"

"Not really" she answered "I would much rather be in a garden or a library."

Loki stared in disbelief. "Me too!" he exclaimed a little frightened of how much they had in common.

"Well, then what are we standing here for?" challenged the girl "Come on! You must have library somewhere in this giant palace."

Loki smirked. "Indeed, we do" he said offering his arm for her to take.

She merely stared at his extended limb, befuddled.

"Oh, you take it" he offered, seeing her confusion. "Why would I take your arm when I have two of my own?" she countered.

Loki laughed and took back his arm. "Alright then, we'll just walk. Follow me." Together they strolled the maze of hallways towards the library all the while chatting of the most random of concepts; their mutual dislike for parties, their mutual love for mischief, or whether chocolate or carmel was a better substance to eat with strawberries. By the time they had reached the library, Loki was laughing as (Y/N) described the prank she had played on her father when he was having a party with the Jotenheim officials.

She and her friends faked an attack by dressing up as bandits. "They were all so frightened!" she exclaimed laughing "they all ran to the cellars to find their weapons but before they could get out we locked the door! Then we ran upstairs and ate and drank our fill. Father was furious, but we were all to drunk to care!"

Loki laughed as he opened the doors to the library. It was empty just as he expected. "So what books do you like to read?" he asked ushering her in.

"Umm… anything really, but books of wizards, dragons, and anything magical are my favorite!" Loki handed her the first book in the series he was currently in.

"Here" he said, "you might like this." Taking it, she opened the cover to the first page and started reading.

"Hang on" interrupted Loki, smiling at her eagerness "don't you want to sit down and find a place to read?"

"Oh! Um, y-yes that would be lovely" she thought for a second. "What's your favorite place to read?" she asked.

He smiled as he silently led her to the back of the library. Here he opened two small glass doors. (Y/N) gasped as a balcony overlooking an awestriking view appeared on the other side of the door. A blanket of stars stretched out above, farther than the keenest of eyes could see. She could see the rainbow bridge reflecting the stars, making it look like a ribbon of diamonds. Down below she could see the crystal water, each wave more clear and beautiful than the first. The air carried a gentle and cool breeze and the music of the party could still be faintly heard.

"If you were to take everything beautiful in the remaining eight realms and compile them together, it would not even begin to challenge this view" (Y/N) breathed. Her hands were on the balcony rail. Loki gently placed his own over hers. She looked surprised but did not move.

"Even before I found I was of Frost giant blood" Loki told her "I have always felt different. I was accepted, sure, but I was different. Never once did I find someone like me." He sighed remembering his year of loneliness. "But now" he said twirling her around making her laugh "Fate has granted me a twin sister" and he added quietly "One I intend not to lose."

"You a very right my dear brother" she said mocking his stature and accent "Let us continue to be melodramatic to the end of ages!" she ended in a mocking flourish.

He laughed grabbing her arms to stop her from moving. "I'm serious though" he said. "I want to be the brother you never had, I want to be able to support you and help you. I want you to trust me." She smiled widely and threw her arms around his neck. Loki was startled and stumbled a little bit, "that makes both of us then" she whispered into his hair. Loki felt love for his new sibling swell and flood all the cavities of his chest.

He encircled his arms around her waist and returned the heart-felt embrace.

She pulled back smiling and saying, "I have a feeling that we will not only be good siblings but also wonderful friends"

And so they would be, for unbeknownst to them, fate had woven a path of love and friendship for the two siblings, one that would never be broken.
