Author's Note: Alright, darlings, I know I said that this ought to be a sequel to my Legend of the Seeker story Through the Chilly Mist. Well, haha, I lied. ^_^ My first Loki/OC story will not be about my OC in that story, after all. Worry not, I will still update all of my stories! Please review, or just favourite or follow this story, please! Thanks for reading, darlings!

Please understand that this would not be the typical Loki love story. Meaning that the girl would not be the innocent, good little saint and our favourite villain would not 'turn good'. They will not be enemies and the girl would not say things like 'No, I will never help you! You evil monster! Good always wins!' Yucks... Well, I promise a happy ending for both of them, okay?

Disclaimer: I do not own The Avengers or Thor. If I did, all the Avengers would have been tortured to death by a thousand Crucios and Sectumsempras. The Hulk would have been left to burn in Tartarus to pay for his unforgiveable crime of hurting Loki. Thor would have been forced to endure ridicule of the people on the streets by eating slugs in public. And above all, Loki would have had a perfectly evil powerful girlfriend and a happily ever after!

I am Loki of Asgard,

and I am burdened with

glorious purpose...and a frozen heart.

I am Sapphira of Hades,

and I am burdened with

glorious purpose...and a frozen heart.

/^Frozen Hearts^\\\\\\\\\\\\\\\\\

Sapphira was a most unusual girl in every way possible. She was extremely powerful at magic, feared and worshipped throughout the whole world of magical people. Sapphira was not human, but a demi-goddess. The daughter of a Greek god, Morpheus the God of Dreams to be exact. Her mother was Morgan Le Fay, unfortunately long dead. Before you start bursting with indignant questions, please be patient and understand Sapphira's family history and unique situation.

When she was born, a prophecy was made. She was said to bring darkness and chaos to the mortal world that history had never witnessed, and her full powers, if awakened, will be strong enough to overthrow Zeus. It took the joint efforts of every deity in the Underworld to persuade the universal ruler not to murder the child. A war caused by this quarrel almost raged. In the end of the negotiation, Sapphira's family promise to never make her completely immortal, but the king, in turn, must swear to never interfere with the child's life. Zeus, caught between of being overthrown right then by the ancient dark divinities or being possibly overthrown in the future, agreed. What he did not realise then was that the deal did not forbid the girl to use her own powers to become immortal. Morpheus, already expecting Zeus to realise his mistake anytime, secretly used his own illusion powers to deceive almost everyone else into believing that his daughter was dead. The only people who knew the truth were Nyx, his mother, Thanatos and Hypnus, his brothers, Hades, Lord of the Underworld, and Hecate, the Goddess of Magic. All these divinities shared a single aim: to defeat Zeus. And their most assured hope was the prophecy child, Sapphira. They made her exceptionally powerful, but she was not fully immortal. The little girl had long since grown into a young lady, and accepted her destiny and potential. She spent a few centuries' time to learn magic, her power growing every single day. Sapphira's own ambition to take over the human world first made her try an almost crazily dangerous spell that was supposed to make her invincible, but the unexpected price was that her heart was frozen. Hecate, upon hearing the situation, gave Sapphira the ability to unfreeze it, but once she did so, she would live in terrible pain. So from that day on, Sapphira remained with a frozen heart, almost impossible to go through emotions and sheltered from human weaknesses.

She found that she preferred the way she was. But deep inside, Sapphira hoped that one day, someone will come into her life and make her feel again, to melt a little bit of her heart without causing her pain.

Present time, Sapphira returned to reality from her thoughts and memories. She had tried to take over the wizarding world by helping the powerful dark wizard, Voldemort years ago. But he was mortal, after all, and in the end, despite all their trying, he perished at the hand of a silly little boy. Sapphira was very angry, more so at herself than at the failure. She had almost felt something for the handsome Tom Riddle the teenager! No, no, human emotions were something she can never afford to experience. Love made people weak, power made you strong.

Sapphira smiled emotionlessly into the gold-rimmed mirror of her bedroom. She still appeared a girl of fifteen, or if she applied darker and more mature make-up, seventeen or twenty at the most. A side effect and a gift for being frozen the inside out. She was beautiful beyond human imagination: hair as dark as the gloomiest midnight, pale skin, perfectly shaped rosy lips. The thing that stood out most about her appearance, however, was her eyes. They can only be described as chilling and magical - the most electric sapphire blue at the rim, but near the middle there were radial patterns of pale blue that seemed to be floating ice. The pupils, catlike. Countless people shuddered at the eeriness of Sapphira's eyes, but she knew that they symbolised her power over ice and hearts. She gazed at her perfect image for another minute, then the boredom produced by her frozen heart started to take over, and she immediately stood up, dressed in an exquisite black dress, black heels. Dark make-up to not be thought as a little girl. As usual, she plucked a lovely poppy flower from her many, many poppy vases, wore it on her hair, and walked out of her apartment. Because of all those damned people who wanted her dead or captured, Sapphira now had to flee from Britain and actually Europe all together - she cannot afford a scene when she was still not fully ready to show the world who and what she truly was. So now, she had to stay in this pathetic modern city full of filthy muggles - New York. (A/N: No offense to Americans, I merely wrote this sentence to fit in the plot.)

The moment she stepped outside, however, a wave of electric current seemed to hit her. She gasped. The source of raw power was almost hypnotizing, excuse the irony. It was the closest to a true feeling she had felt in real life for a very long time. Sapphira at once closed her eyes and followed the pull of the alluring power. It was new, completely. As if it did not come from this universe, but perhaps that was exactly the case. She teleported herself to the location, wherever it was, and when she opened her eyes once more she groaned as she recognised where she was - S.H.I.E.L.D. Great, just where she need to be, the universally famous Department of Shits. Some of her useful minions were defeated by this accursed department, hope all the supposed Avengers rot in Tartarus. In spite of the slight disappointment, Sapphira proceeded toward the direction where the power was calling. A guard saw her and started walking toward her.

'Miss, how did you get in? This is - ' Before he even started to call for his superiors, Sapphira acted quickly and pulled his heart of, in an instant freezing it, before shoving it back to his chest. At once the man's once brown eyes turned a strange frozen pale white-blue colour, like the patterns in her own eyes. His face looked blank as he automatically kneeled before the girl known as the Mistress of Hearts.

'Mistress, how may I - ' The man was cut off almost instantly, however, by his impatient Mistress.

'Tell me, did anything strange happen here, tonight?' Sapphira questioned quickly.

'Yes, there is something called a Tasseract in that room, and just now it shot out some strange blue light, and oh, a strange man appeared, we are told to stop him if he comes our way, and...' The guard's eyes suddenly widened fearfully, 'Mistress, you have to hide! I need to protect you! I think that man is coming this way right now, the voice, wait, I need to call for help - '

'Oh I don't think so.' Sapphira replied in a bored voice, 'Kill yourself, now.'

At her command, the guard at once dropped dead on the spot, clutching his chest as he went down to the floor.

She looked around, and before she can continue walking, a man with a scepter appeared with a few followers. Sapphira narrowed her eyes curiously. Incredible power was radiating off him and the scepter in magical waves, and she almost lost herself in the wonderful scent of power. Not the raw power that she felt earlier, but extremely powerful nevertheless. The most fascinating was that the magical energy that drew her here in the first place seemed to be, for some reason, in the suitcase carried by one of the followers. Sapphira decided not to mention it straight away, though. She took her sweet time to take in his appearance at the same time that she seemed to be observing hers. He had dark, slicked back hair, pale skin, thin lips that even Sapphira the Ice Queen herself had to admit as sexy, and such coldly bewitching green-blue eyes. That man was just as inhumanly handsome as he was powerful.

A brief but magnetic eye contact confirmed that the appreciation worked both ways.

A short but welcoming silence followed before the man smirked, real charming, and Sapphira found herself doing the same thing at exactly the same moment.

'Mind talking outside this place, my lady? I've got a hundred guards on my tail already.' He flashed her a confident smile, showing perfect white teeth.

'Why, of course, my lord.' She replied, equally polite, gladly enjoying a civilised and well-educated conversation in the land of mortals for once.

They left the place quite smoothly, with the mysterious man's servants shooting about a dozen guards along the way. Sapphira casted bored glances at the bodies, and she can feel the other stealing curious glances at her cool attitude toward killings. She observed the servants, and noticed that their eyes were all a glowing blue colour like the gemstone on the scepter, and all their faces were strangely yet familiarly blank. Sapphira smirked. The scepter must have the power to control people. Interesting.

They seemed to be going into some kind of a basement, and it was obvious that the man prepared for her bombarding questions. She surprised him by speaking nothing. Why should she ask questions before even arriving at a suitable room? It was not as if she had anything to fear. Sapphira was a soon-to-be goddess, after all. And then again, she cannot feel fear. Or anything else almost for that matter.

At last, they reached what was apparently their final destination. A meeting room of some sort, decorated with green, black and gold. In fact, the colour tune here was almost all like this - someone's favourite colours, obviously.

'Leave and take care of it.' The man commanded, voice the same silky quality that Sapphira enjoyed particularly.

'Yes, master.' The servants responded monotonously before quickly exiting the room, leaving the two of them alone.

'So, I suppose that an introduction is in order, Lady...?'

'Sapphira, my lord.' She answered.

'Beautiful name, fitting,' He cocked his head to the sky and narrowed his eyes, 'I can feel it, you are powerful. You are not human, are you?'

'Are you?' Sapphira echoed slyly.

He smirked at her, as if satisfied. 'No, indeed I'm not. I am Loki, the God of Mischief and Lies.'
