She was his, and that, was how it always was.

When they were mere children, Loki could remember how she looked at him, it was how every man wished his lover to look at him. Hazel eyes gleaming with love, admiration and desire. It almost dripped from them like liquid gold, precious and beautiful only making his emerald eyes gleam with envy. Her full lips, slightly a gape as Thor successfully defeated his third sparring partner.

Sifs hair seemed to match Thor's almost perfectly, like Odin had made them that way, in the hope that one day, they would produce perfect children whose hair gleamed like the sun.

She was tall for a girl, a strong athletic build, with distinctively long legs, even as a small child. As many years passed, Loki watched her grow. Each day she was blessed with with more and more radiant beauty. Long gleaming gold hair, and strikingly hazel eyes. Her and Thor became inseparable.

This irritated Loki, but at first, he couldn't figure out why, as a small boy, he believed it was pure disdain, towards this golden haired goddess, who wielded a sword better than he and was purely infatuated with his brother. Whom pitied and patronised him, who always ignored his efforts to fit in, who laughed at his magic and teased him to no end.

But after his transition from a boy to man he realised that hate was nothing more than jealousy. He wanted to look like the sun, like the other asgardians, he wanted to be a good warrior, to be loved, to have her look upon him like she did his brother.

Loki could not have been more opposite, he was a tall slim frame, his hair black as night, his skin like ivory and his eyes an enchanting shade of green. He was no warrior, he was a sorcerer, Loki loved to read, research and experiment, he was an artist, a scholar and an enigma in more ways than one.

Chapter 1 - Jealousy

It had been a hot day in Asgard, Loki detested the heat, it was almost like he could feel himself melting away in it. He had made his mind up, he was to stay in doors.

Loki found himself a comfortable spot in the palace library, he sat at the small golden desk and began to read a new potion book titled "The art of appearance" with the envy of Thor's golden hair growing Loki had decided to research deeper in trying to change his own appearance. Despite his loathing of vain, superficial imbeciles, his curiosity had gotten the better of him.

Within moments of getting comfortable, Loki was alarmed by the clanking of armour and someone's heavy steps coming towards him. Panicked, Loki threw the book onto the floor and kicked it under the desk, his research on such a topic was to remain a secret.

Much to Loki's surprise, there stood the infamous Sif in front of his tall, her silvery armour shone magnificently, she looked so regal and strong. Puberty was serving her well, her armour was now modified to display her new and more womanly body shape, she had never looked more like a goddess than she did now.

Arrogantly flipping her luscious golden hair, she looked directly and Loki,

"Why are you in here on such a beautiful day Loki? Thor, Fandral, Volstagg and Hogan and I were just about to play a game of hide and seek in the gardens, we need someone to come looking for us, will you join us?"

"Does it look as though I have time to play such childish games to you?!" Loki snarled.

"Well it hardly looks as though you're doing anything of any real importance to me, I know lady Frigga would like it if you joined us, she worries for you sitting in here alone all the time."

"Don't involve my mother in this, I choose to spend my time in here constructively rather than gallivanting with you and your half wit friends." Loki said, casually, whilst pretending to be reading another one of his books.

"Well aren't you delightful this afternoon. I was only asking, I didn't realise the heat affected your mood swings so much."

Just as Sif turned to leave, Loki sighed. "Fine, I'll join your silly game, if it pleases you, Lady Sif."

Sif smiled softly, "it does, Thor will be so pleased."

As Loki followed her into the gardens, his expression darkened, of course Thor will be pleased, his heart jumped a little when Sif had come alone to ask him to join in their game, but it now it was obvious why, Thor had put it her up to it.

As the afternoon dragged on the game became more and more predictable and annoying. Loki's skin began to prickle with the heat and frankly, he wasn't amused. Volstagg was only ever hiding where there was food, Fandral was constantly side tracked, spending half the game flirting with the maids, Hogun was probably the most challenging to find and had a knack of being unnaturally quiet.

This left just Thor and Sif, who, no doubt we're hiding together, much to Loki's displeasure.

The gardens were undeniably beautiful, overlooking all of Asgard, trees and bushes with the most exotic flowers you have ever laid eyes upon. The afternoon sun shone gracefully over the green pillars of the garden.

It was then the giggling caught his ears, eagerly, he stormed towards the direction of the fire Lilly bush, the fire Lilly's were in full bloom, rich red and white flowers decorated the bush intricately. Loki noticed an opening in the shrubbery, a clear indication someone had rummaged their way through it rather indiscreetly.

Pushing his way through the small gap, he suddenly stopped, point blank in his tracks. There was Sif, sat, infact, straddling his brother, kissing him like he had never seen before. Not like the small pecks they exchanged normally, he could almost see their tongues dancing with one another, roaming one another's mouths.

Loki felt hot and sick. Something in his heart cracked that day. It felt like it had hit his stomach, like nothing he had ever felt. It was then and only then, he realised he was infatuated with Sif and in that same moment, he realised she was in love with his brother, and would never love the lanky sorcerer with black hair in the same way.

The same evening at dinner it was tense, Loki had seen what he'd seen and Thor and Sif were well aware. Loki slipped off quietly, being the god of mischief and being a notably jealous person had proven a bad concoction at this moment in time.

He had retrieved his spell book from earlier, carefully revising the page "Curse of the crow hair."

Loki knew this was a spiteful trick, even for him, but nothing could stop him, he was fuelled with rage and jealousy, he was livid. His brother and Sif had become everything Loki hated recently and he made it his mission to shatter their insufferable arrogance and vanity once and for all.

Using a spell to appear invisible, Loki, with a knife in one hand and potion in the other, slid like a serpant into the Lady Sifs chambers. There she lay, soundly, possibly even more ravishing as she slept, blissfully unaware of Loki's cruel intentions.

After cutting the first golden lock from the warrior goddesses hair, the rest seemed to just drop off, cutting, slashing, ripping in swift, graceful movements. Once the lady was free of her silken gold mane, he then dripped the potion on to her scalp, suddenly, long, thick, black strands of hair grew rapidly from her scalp.

Within moments, her hair was long, black and very much like his. One thing was for sure, she would never forgive him for this.

Weeks passed, and no one could find a reverse spell for the cruel trick. Sif despised him for it, loathed him, however Loki was somewhat pleased with himself. The years passed and they all grew, Thor and Sif had gone from lovers to best friends, Thor found himself entertained by the foolish bore-some girls of court and Sif focused more on her warrior duties. Loki was a man now, a man of magic, a god, and as the many years passed, his intense jealousy only grew stronger.
