A/N: welcome all to my frozen/thor crossover! since we never really never had an explanation about how Elsa ended up with her powers, just that she was born with them, I figured i'd give her them an origin. here's my spin on it! hope you all enjoy!

Chapter 1: Such Talents

Loki sat in front of the fireplace on the floor in his chambers, reading a book of magic, intently. He'd read a certain paragraph three times over. The wording threw him at times in some of the books and he had to reread many of the paragraphs, but this particular paragraph was about something he'd never heard of before.

"Loki?"

He jumped with a start before looking to his chamber door to see his mother and mentor in magic, Frigga, stroll into the room, looking at him in wonder as she approached.

"Oh, good evening, mother," he smiled, standing as he held his place in the book with a finger between the pages to hug her tightly. "Come to say good night?"

"Yes," she smiled, giving a small laugh as she hugged him in return before looking to the book in his hand. "Still having trouble with it?"

"I'm astounded by this section," he explained, holding the book up to open it, showing her the paragraph he'd reread about five times. "Is it true that when a woman is with child you can infuse magic into the unborn baby?"

"It is true, though it is highly reckless," Frigga replied, examining the book. "And a burden for a child to be given a responsibility it cannot comprehend for the first parts of its life."

"You taught me magic when I was naught but five," he recalled, pulling the book back to examine it as he stepped toward his desk at the other end of the room.

"Yes, but you had an understanding of it," she countered. "There is a difference. To start out with so much untamed power can be devastating, especially to someone so young."

"But what if the child were befriended at the right time by another sorcerer?" Loki asked, the wheels turning in his head as he turned to Frigga. "If they were mentored as you did me."

"It is not the same, Loki," she insisted, stepping toward him to pull the book back slightly on the desk, catching his attention as she shut it and smiled, warmly at him. "Why would you attempt such a scheme, my son?"

Loki sighed, lifting a hand to run it through his raven locks before replying, "You know I love my brother as I should, but at times…he does not understand me. He has father's adoration and I am left to the wayside many a time. I am tired…of being so alone."

Frigga felt her heart clench in guilt before wrapping her arms around his shoulders to set her head on one of them, making him smile, slightly at the show of affection.

"I caution you, my Loki," she murmured. "An old Midgardian saying says, 'If one plays with fire, one will be burned.'"

"Just as well for me, I can flick fire away with the talents you've given me," he smirked, cheekily, making her pull back to give him a chastising glare. "Alright, mother. I'll not attempt it."

"You will," she sighed, making him frown, slightly. "Do not think I am stupid, my son. You will attempt it, and I cannot stop you. But I still caution you."

He chuckled, lifting a hand to hers as it sat on his shoulder, smirking, "You know me far too well, mother."

"Yes, I do," she nodded, leaning down to press a kiss to his hairline. "And you'll do well not to forget it. Good night, my son."

"Good night, mother," he nodded before she turned to head for the door.

He turned back to his book and studied the paragraph again before looking to the wall of books in front of his desk, looking for a particular book. When he spotted it he lifted his hand to use his magic to pull it from the shelf and open it as it floated toward him. He set it in front of him and flipped through the pages before he found what he was looking for: a map of Midgard. His eyes scanned over the list of places in the realm that thought he and his family were gods before coming to the places that worshipped them for the most part.

"Arendelle," he murmured with a small frown then grinned. "I quite like the sound of that. Time for a trip to Midgard."

One Month Later...

He watched her sleeping, her pregnant belly swelling under the sheets of the bed she shared with her husband. He stepped closer on silent footsteps, cloaked in an invisibility spell so as not to wake them, and if they happened to wake, they wouldn't see him.

Arendelle.

He had loved the sound of that name, and the country was beautiful. His fascination didn't stop with observing the place from Asgard, however. He'd walked among the people, acted as a servant in the king and queen's castle, just to have a look at them. They were good people, trying to have a child to carry on rule of the country.

Now, the queen was with child, and he knew she hoped for a girl…a special little girl.

"Why should your wish not come true, your majesty?" Loki smirked to himself before raising a hand and pulling back the covers to press his hand to her belly. "A very special little girl for a very special kingdom. Blessed by the God of Mischief himself."

A golden flash came from his hand, and just as it did, the queen gasped awake, feeling it as the baby's kick. Loki stepped back, still cloaked in invisibility as the queen's sudden gasp woke the king as well.

"Darling? Are you alright?" he hoped as Loki watched them both, unmoving.

"Yes," she nodded with a sigh, running a hand over her belly before smiling, "The baby just kicked and startled me."

The couple settled back down to sleep and Loki couldn't help but smirk as he disappeared, leaving the castle to go back to Asgard.

Several Years Later...

"Do you wanna build a snowman?" Anna drawled at her sister, Elsa, who was trying to sleep, but found it difficult with her little sister lying on top of her and urging her to play.

Elsa opened one eye to peer at her grinning, freckle-faced, red-headed sister. Unable to resist her any longer she shoved Anna off of her, sending her to the floor with a grunt and sat up to jump out of her bed. Anna giggled happily as she stood, making Elsa shush her and Anna slapped her hands over her mouth, but it did nothing to stop the giggles.

"We can use the ballroom," Elsa whispered before they raced to the door, but she stopped short, letting Anna race past her and into the hall.

A strange chill had gone up her spine, making her stop and look back into the room. She knew it was empty, but she felt as if she was being watched. She had felt it when she had been trying to sleep but when Anna climbed onto her bed, she figured it had been her staring. But now, the feeling was back, and having felt it before when she was alone, she was beginning to ignore it. This time, though, there was something different.

"Elsa! Come on!" Anna whispered, harshly before grabbing her sister's hand to drag her down the hall.

"Anna, slow down!" Elsa giggled, the feeling now forgotten as she was pulled toward the ballroom.

"Do the magic!" Anna giggled, jumping up and down next to Elsa.

A dark figure watched the girls from a corner. He grinned as Elsa froze the floor with a stomp of her tiny foot, then chuckled as the girls romped through the snow Elsa made. They made a snowman and named him Olaf, claiming he liked warm hugs. Elsa pushed them over the ice floor with cold winds from her hands.

The figure watched as Elsa made piles of snow for Anna to jump on, catching her from falling each time, but his smile fell when he realized Anna was jumping higher and too quickly for Elsa to keep up.

"Wait! Slow down!" Elsa begged, trying to keep up, but she slipped just as Anna jumped off a snow pile. "Anna!"

Elsa reached out, her anxiety causing her to hit Anna in the head with a burst of ice rendering her unconscious as she fell onto a nearby pile of snow. Elsa raced toward her as the figure, cloaked with invisibility from view, followed to look over Anna. A white streak appeared in the red locks as Elsa cried over her.

"Mama! Papa!" she sobbed, but with her panic, fear and anxiety, the ice spread through the room, frigid and untamed.

Loki watched the girls' parents burst into the room, backing away to let them care for Anna, later taking them to the trolls of the land. He wished he could have helped the child, but it would have involved revealing himself, and he had only planned to show himself to Elsa, the one he'd blessed with the gift of sorcery.

He watched the king and queen take the children away, and once the door was shut Loki waved a hand, the ice disappearing from the room with it. He thought of waiting for the child in her room, then guessed she would be too worried about her sister to hear what he had to say. He would have to wait just a little longer to mentor his little ice princess.

One Week Later...

Elsa sighed as she read her book sitting on her bed then jumped when a call came from her door.

"Elsa?" Anna called before knocking a beat on her door, and Elsa sighed shortly again, bowing her head. "Do you wanna build a snowman? Come on! Let's go and play! I never see you anymore. Come out the door. It's like you've gone away. We used to be best buddies, and now we're not. I wish you would tell me why."

Elsa felt a stab pierce her heart at hearing her sister plead for play and explanation. She didn't like keeping things from her sister, or not being able to play with her, but she didn't want to hurt her again. If it meant being isolated, then so be it.

"Do you wanna build a snowman?" Anna called again, making Elsa roll onto her back in exasperation. "It doesn't have to be a snowman."

"Go away, Anna!" Elsa called, sadly as she closed her eyes, trying not to feel, like her father had suggested.

"Ok, bye," Anna murmured.

Elsa felt tears coming to her eyes before she jerked with a sob, her hands flying to her face to cover the sounds of the other sobs she gave. Ice spread out from under her, freezing the covers she lay on top of and spreading until it covered every part of her bed.

"Well, that will certainly be uncomfortable to sleep on tonight, will it not?"

Elsa gasped and sat up, her eyes darting around her room, but she couldn't find the man the voice belonged to.

"He-Hello?" she called, cautiously, curling up on her ice-covered bed. "I…I've known you were there. I felt you watching me. You can come out. I promise I won't scream, or call the guards."

A shadow was cast over her, causing her to turn to her window and gasp when her ice blue eyes locked with sea green. A tall man wearing mostly black leather with flashes of gold and green appeared from what seemed like thin air, his black hair slicked back and his hands behind his back with a smirk over his thin lips.

"Your Highness," he smirked, bowing before he stepped closer to the bed where she still sat, her eyes wide as he approached. He stopped at the edge, staring down at her as she stood up on her bed, and even with the help of her mattress, she couldn't reach his full height to be eye to eye with him. "I hope I didn't frighten you terribly."

"No," she replied, and his smirk widened under her scrutiny. He remained still under her gaze as she examined his face, then his clothes as he watched her before she spoke again. "You look familiar."

"I should think so," he smirked, making her frown at him in wonder. "Your ancestors worshipped me for some time. I imagine my likeness is somewhere around this fine palace. If you'll excuse me."

He lifted her off the bed, making her gasp in surprise before he set her down next to him as she stared at him with wide eyes. He waved a hand over her bed, making the ice disappear, and Elsa grinned before scrambling up onto the bed and jumping on it as she laughed.

"Now I know who you are!" Elsa grinned, slowing her jumping as she faced him again. "You're Loki!"

"Very good, little ice princess," he smiled with a nod. "Second Prince of Asgard and God of Mischief, at your service, milady."

"What are you doing here?" she wondered, flopping onto her bottom to sit and stare up at him.

"Well," he drawled, his hands behind his back again as he strolled around the bed. "I look in on this realm occasionally, and I…sensed your powers over ice and snow. You have a lovely talent, Princess."

Elsa's smile fell, making Loki frown, wondering if she'd detected his lie, but he only noted sadness in her eyes before she cast them down to twiddle her fingers in front of her.

"I don't think it's lovely," she admitted in a murmur, making his frown fall away as a small stab was felt in his heart, but he hid it. "I hurt my sister with it. That's why I can't play with her anymore. I can't control it. Sometimes…I just touch things and they turn to ice."

Loki smiled, warmly at her before sitting at the foot of her bed and taking her tiny hands in one of his huge ones. She looked to him with wide, teary eyes, making his smile widen, slightly as their gazes met.

"I can teach you how to control it," he assured her, making her eyes widen in disbelief.

"Really?" she grinned, his hand falling from hers so she could sit next to him, making him give a chuckle.

"If you'd like," he nodded. "I was not born with my talent, but I was taught by my mother. I can certainly teach you something as simple as control."

Elsa grinned, brightly as she clapped her hands in excitement, her feet kicking over the edge of the bed and nodded vigorously, "Yes, yes! Please, Loki!"

"As my princess commands," he nodded with a smirk as he stood from the bed, bowing low and holding a hand toward her. She set her hand in his, marveling at how large they were compared to her still tiny ones before jumping off the bed, her hand still in his. "Why don't you show me a bit of what you can do?"

"But…you've seen what I can do, right?" she frowned in wonder, then giggled as he twirled her by the hand.

"Yes, I have, but I like to see you use your talent," he smiled, kneeling to look her in the eye. "Go on, darling. Let's have some fun with it before our lesson, yes?"

Elsa couldn't help but grin as she nodded before he stood and she clasped her hands together, making some snow then threw it up into the air, making it rain down on them.

"Beautiful," Loki smiled as she twirled around before he winked at her, adding, "Now, watch this."

With a wave of his hand, a small cyclone of snow floated in it, and he lowered his hand for her to see.

"Wow! I can do that too!" she marveled before doing the same gesture he had, only the cyclone was as tall as she was and its base sat on the floor.

"Be careful, now," he warned as she made the cyclone move faster and faster and he could see that was going to lose control. "Elsa, slow it down."

"Huh? Whoa!"

Elsa fell back onto her rear as the cyclone shifted and knocked her over before spinning out of control around the room, knocking things over and picking up papers and smaller trinkets on its way. Loki knelt down next to Elsa to be sure she was alright before slicing his hand through the air at the cyclone and it disappeared, the objects it had picked up falling to the floor.

"You must be careful, little one," he murmured, helping her stand and dusting off some snow from her dress. "Part of having control is to know your limitations. If you feel you may lose control of something, pull back."

"Maybe this isn't such a good idea," she muttered, making him frown at her in wonder as she kept her gaze cast down in sorrow. "Papa's right. Conceal, don't feel. Papa is always right."

"Conceal?" he echoed, still frowning. "But why? Your talents are beautiful. You shouldn't have to hide them. Just a few lessons in control and you will be the greatest sorceress in all of Arendelle. But you must be patient."

"No!" she snapped, making him pull back as she turned away from him. "I won't hurt mama or papa or Anna ever again. I won't use them, I won't!"

Elsa turned, raising her hand and struck at Loki, but he lifted his hand, girded with an armguard, making the snow and ice she shot at him bounce off of it without harming him. She gasped when she realized what she'd done and backed away from him in panic, each footstep causing ice to spread with every step she took.

"Elsa, stop," he urged, holding a hand toward her but she shook her head. "You are freezing your floor. You must calm yourself."

"No! Stay away! I don't wanna hurt you!"

"You won't hurt me. Come here."

"No!"

Loki grabbed her hand and pulled her toward him to hug her as he still knelt down at her level. She gasped but she didn't pull away as he hugged her and she let herself relax, her little arms rising to hug as much of his shoulders as she could. He sighed in relief when the ice stopped and he waved a hand over the floor to make the ice disappear. He pulled back and gently took her face in his hands to make her meet his gaze.

"You listen to me, Elsa," he whispered, lowering his hands to her small shoulders. "You will never hurt me. You can't. It's impossible. Whatever ice and snow you throw at me will do nothing, understand?"

Elsa swallowed before nodding and he gave a smile before lightly pinching her cheek and she couldn't help but giggle.

"Now, I have things to tend to in Asgard," he reported in disappointment, lifting one of her hands and covering it with his other as he looked to her worried frown. "Royal duties are never done, yes?"

Elsa nodded as she sulked, looking to their hands before he took her chin into his thumb and index finger.

"Will you come back?" she wondered, making him frown in wonder before smiling as he lowered his hand to lift one of hers and press a kiss to her fingers.

"Of course I will, princess," he smiled. "I won't leave you alone, I promise."

She grinned and threw her arms around his neck to hug him tightly, making his smile grow as he hugged her again, kissing her head.

"Thank you," she whispered.

"You're welcome."

Some Years Later...

Fourteen year old Elsa straightened out her skirt as she stood in her room waiting for Loki. He had promised the night before to return the next day, and over the years he'd been coming to see her, she found that it wasn't just his teachings she looked forward to, but his company as well. When she was younger, she loved it when he engaged her to use her powers, and as she got older, they would talk or he would read to her, or vice versa. She felt she could be herself with him, something she couldn't be with anyone else.

"You look wonderful, Elsa."

She jumped with a start before turning toward the window to see Loki smiling warmly at her.

"Loki!" she grinned, racing toward him to hug him tightly as he chuckled, hugging her in return before she pulled away again, but they froze when a knock came to the door. Elsa knew exactly who it was as she placed a hand over Loki's mouth to keep him from alerting Anna to his presence.

"Do you wanna build a snowman?" Anna called. "Or ride our bike around the halls? I think some company is overdue, I've started talking to the pictures on the walls. It gets a little lonely, all these empty rooms, just watching the hours tick by. Elsa? Do you wanna build a snowman?"

Elsa's hand fell from Loki's face, making him frown at her, but her expression read sorrow as she glanced back at her door before looking back to Loki. They heard Anna's footsteps heading away before Loki placed a hand on Elsa's shoulder to turn her attention to his smile, making her smile back, weakly.

"I brought the book I was telling you about last night," he smiled, holding said book up for her to see as her smile turned to a grin, lifting her hand to take the book but he gripped one of her wrists, making her frown at him in wonder. He frowned as well at her gloved hand, and realization hit her.

She'd always been very careful not to wear her gloves around him when her father suggested that they would help keep her powers in check. And they did, for the most part. Loki always disapproved of concealing her power and holding back, which is why she never wore the gloves around him.

"A bit warm for gloves, isn't it?" he asked, raising a brow at her in question, making Elsa swallow hard as she met his gaze.

"W-Well…" she sputtered, now trying to avoid his gaze as he still held her wrist before she finally shrugged, casually, "I-I'm just feeling a bit cold."

"The cold never bothered you," he smirked, stepping closer to loom over her as she stared up at him again. "You cannot lie to me, darling. I am the Prince of Lies. Let me have a guess. Your father suggested you wear these to keep your talent under control, yes?"

Elsa nodded, casting her gaze away from him as he released her wrist to set the book down on her window seat before taking her hand in his. He slid the glove off as she watched him when he lifted her hand to leave a kiss on her skin, his eyes meeting hers again and he gave her a wink. She gave a small giggle before he lifted her other hand to slip the glove off and repeat the gesture, finally causing a very faint blush to appear on her cheeks.

"I call you my ice princess for a reason, Elsa," he smiled, taking her hands in both of his, looking her in the eyes. "Your talent should not be concealed. And you will be able to control it, with time."

"But…if I haven't been able to by now, perhaps I never will," she despaired, tugging her hands from his to turn and look to the corner near her door that was iced over. "Look! I did this just a moment ago! It's getting worse, Loki. I can't even touch my parents because I might hurt them! I can't touch…anyone."

Loki stepped toward her as she turned back to him and he took her hand in his when she looked to him in wonder. He lifted her hand and placed it on his cheek, making her ice blue eyes widen at him when he nuzzled her palm, keeping her hand in place with one hand. He met her gaze and gave a warm smile, making her swallow as her heart skipped a beat.

"I told you when you were a child, that you will never hurt me," he reminded her. "That is still true, darling. So, if you cannot have the closeness of your parents, or your sister, or anyone else, then, my lovely Elsa, I will have to suffice."

Elsa felt tears come to her eyes, and her emotions spread to her hand that was still pressed to Loki's cheek. Her eyes widened when she noticed his skin starting to change color, from its usual pale pigment to a strange blue she knew was not coming from her abilities.

"What?" he frowned in wonder as she pulled her hand away. "Elsa? What's the matter? You don't look well."

She stared on, silent for a moment before she gave a small frown when the blue patch of skin diminished again, going unnoticed.

"Elsa?" he asked again, bringing her back to his senses.

"I'm sorry, Loki," she smiled, nervously before stepping closer to press her hand to his chest as she met his gaze. "Will you read that book to me before you leave?"

"Y-Yes," he nodded, taking her hand and pulling her back toward the window seat to lift the book and sit on the cushion, Elsa gracefully sitting next to him. He handed her the book, making her frown in wonder at him before he smiled, "I would much rather have you read to me, darling."

"I would love to, Loki," she smiled, opening the book. "It's my turn, is it?"

"It is," he nodded, and she held the book up to begin reading when she stopped short, feeling something settle in her lap. She looked down to stare at Loki grinning up at her in wide-eyed disbelief that he was being so bold as to rest his head in her lap. "Something wrong, princess?"

"Y-You—! Loki! What do you think you're doing?!" she squeaked, her cheeks stained red against her pale skin.

"I'm merely relaxing to listen to you read," he smiled, mischievously. "Read on, my snowflake. Nudge me if I fall asleep."

"You have many names for me, don't you?" she replied, unable to help smirking as she stared down at him.

"And I may have many more for you until I finally settle on the perfect one," he smirked back before lifting a hand to brush a stray lock of her white hair behind her ear.

"Maybe you should use my name," she retorted, the light blush gracing her cheeks again.

"How dreadfully boring," he muttered, taking one of her hands and setting it on his chest to fiddle with her fingers. "Endearments make things interesting, do you not think so?"

"For the God of Mischief, perhaps," she nodded, leaving her hand on his chest. "Well, if I have so many names, then you should too."

"By all means, my pet," he smirked. "I encourage it, wholeheartedly."

"Lie back and let me read, Mischief Maker," she giggled.

"Ooh, I like that one."

"Quiet! I'm trying to read."

"As you wish, princess."
