AN: Alright, this is not the start of a new story of mine. This idea has been floating in my head for quite a while and I've finally put it to paper. In all honesty, I'm surprised there are so few fics with Loki's children. I mean COME ON. There is so much we as fanfiction writers could do with them. But, I like this premise so much that I had to put it out there for others to see and hopefully be inspired by. It's our privilege, nay, our duty to write fics about what sparks our interest. So read my fellows and be inspired!

Loki laid in his cell counting out how many flaws he could find in the stone work on the ceiling. A very dull pastime, but until moth-Freya, came and give him some new reading material or Thor comes down and tries to 'redeem' him by blathering on like a buffoon for hours on end, he was left with little to do.

Unconsciously, he tried to use his magic to entertain himself only to scowl when his body heated up thanks to Odin's curse on him. What little magic that was left to him caused his body's internal temperature to skyrocket and as a Frost Giant, that is absolute torture. He had to commend the All-Father, he certainly has not lost his touch when it came to inventive 'punishments'.

"Indeed he has not." An unfamiliar voice echoed through the cell causing him to jolt upright as he had not sensed anyone approach. When he looked out his cell windows/walls, all he saw was an inky blackness. Wary, he prepared his magic for whatever intruder had come for him. "Calm yourself, young prince. I assure you, I mean no harm."

"You'll have to forgive me for not believing someone whose covered my cell so no one could hear me."

A chuckle that didn't echo so much as cause the floor to vibrate caused him further worry, though he masked it well. "I'm impressed. Few would be able to understand what I have done without using magic of their own. And yet you could tell by just a glance."

"Flattery will get you nowhere. Now show yourself or face my wrath."

"We both know that to be an empty boast. But I suppose we should dispense with the pleasantries, though I'm afraid that I'm not physically here."

"Why are you here?" Loki demanded. He had relaxed a little as whoever this being was, they were not here for retribution for his failed takeover of Midgard.

"I just want to make a deal with you."

"A deal? Somehow I doubt I could contribute anything while locked in here."

"True, very true. But I know you will not stay caged forever. Events beyond your control move ever onwards and only your death will keep you from ever leaving. But that is not what I desire. Tell me Loki, Prince of Asgard, Heir to Jotunheim, what would you be willing to give me, to sacrifice in exchange for your children."

Loki froze, chills dancing up and down his spine. "I don't know what you refer to," he managed to bite out.

"It is unfair, isn't it?" Loki got the distinct impression of hands gripping shoulders while someone whispered into his ear. "Their only crime in the eyes of everyone being that they were born or because you were their father. Bound and chained, tossed to the deepest oceans on another realm, dammed to Hel for all eternity, treated like a trophy only to be ridden on, and let's not forget the youngest pair who paid for your crime with their very lives."

Loki swallowed. This being, whoever they are, knows far too much about things that were never let loose from the halls of the palace. Not even the palace's staff knew any of this. He felt a particularly powerful ache at the mention of his youngest. "How could you possibly know all of this?"

Another reverberating chuckle was his answer. "The All-Father has made many enemies."

"And you are one of them." Loki stated.

"Not particularly. He has certainly not done anything to me to warrant any animosity."

"Then why?"

"The All-Father is what mortals would refer to as a chess master. Plans within plans. Plots concealed from even trusted allies. Even their own families are not beyond their machinations. Always several steps ahead, always willing to sacrifice for their goals, just not themselves. To be sure, they play a critical role in a civilization. It is an occupation that someone has to fill. Their actions can even be commendable. And yet I cannot help but despise them."

"What is it that you want?"

"Entertainment of course! To see how the mightiest of realms devolve into panic will be such an exquisite sight."

"You would risk Ragnarok for entertainment?" Loki didn't know whether that was commendable or moronic. Probably both. "I still don't know why you have come to me. I do not know the locations of my children, besides my daughter. Even Sleipnir is kept from me. I can see in no way how I can contribute to this deal. Even still, some of my children are bound by powers I cannot even touch. And I highly doubt even you could overrule the laws of the realm of the dead."

"It is true that your daughter is beyond my power to free. For now. As for why I have come for you, let's just say you'll owe me. A favor for every child."

"A favor from a fallen prince?"

"Disgraced you may be, but a favor from an imprisoned god, is still a favor from a god."

"Oh? Haven't you heard? We are not gods."

A roaring laugh that rattled his bones shook his cell. "What defines a god? Power? Knowledge? Control over life and death? Two of these you exemplify. You wield arcane arts on a scale most cannot comprehend any more. Does this not qualify you for godhood? Your knowledge is vast enough to rival the All-Father. Just because there are those stronger than you out there, does not make you any less of a god."

"Still, I cannot hold this concealment from much longer. Heimdall, will notice the disturbance soon. Deny me my entertainment and your children their freedom, or," a scroll appeared floating in front of his face, "sign on the dotted line."

Loki knew he shouldn't trust this entity at his word, yet at the same time the offer was far too tempting. More than even The Other's offer of ruling Midgard. How long has it been since his children were taken from him? How long have they suffered for his actions? Far too long. "I don't have a pen."

"A few drops of blood is all that is required." Loki brought his thumb up to his mouth and bit, drawing blood, then swiped the appendage across the line at the bottom. The scroll disappeared in a flash of flames and his wound healed. "I thank you for your cooperation. And now I must bid you adieu." Loki blinked and the darkness that covered his cell was gone. Shaking slightly, he sat back on his cot and stared at his hands.

"What have I done?"

Elsewhere

A man broke out of his stupor with a gasp and took a look at his surroundings. Feeling something in his hand, he looked and saw a rolled parchment. Slowly a chuckle bubbled from his chest before he threw his head back and let out a victorious laugh. After he calmed, but still with a victorious air around him, he walked towards the other side of the room where a large cauldron sat, boiling. Checking the scroll till he was satisfied, he then threw it into the cauldron, causing the liquid to flash through several colors before turning clear.

What Loki didn't know was that the contract was meaningless. It was only his blood he was after, for it was through the tricksters blood that his children could be found. "Let's see," he murmured, "if I remember correctly…Find Fenrir." The surface of the cauldron swirled before changing back to its mirror like state. This only made the man grin wider. "Lets try…Find Tyr's missing hand." The cauldron swirled before the image of an island on an uncharted realm came to view.

Magics that are used to hide something have to be specific in what their hiding. So while the Wolf cannot be found, the missing hand that Tyr lost to it when it was chained could. Fortunately, Fenrir was the hardest hurdle to overcome. He had spent literal days pouring over everything he knew about the Wolf before he even started this venture. But, while strong magics shrouded the Wolf, the Snake isn't. It's mere size too grand to hide, as you'd need to hide the entire realm. Unfortunately, Sleipnir is out of his reach as he's constantly guarded by Aesir royal guards, plus Heimdall and Odin, and Hel is also out of reach as she is bound to the realm for which she is named after…or was it named after her? He could hardly remember, nor care. To take Hel out of Helheim would throw a lot of things out of balance as someone else would need to take over and the prospects was rather short, i.e. none at all. As for the youngest two, he will have to entreat Hel somehow.

First things first, he needed to actually do as he had promised. So with a spring in his step, a dark chuckle on his lips, and power cloaking him he set out to give everyone a major panic attack.

Later

Loki laid on the floor in his cell going over just how stupid he had been. He continued to list the various things whoever that he made a deal with could do with that blood. He never even read the damn thing. For all he knew, it was lying about how much longer it could hold its spells. Running feet made him stand up, curious as to what was happening.

"LOKI!"

Blinking in surprise, he beheld the site of his not-brother and not-father surrounded by several of the oldest royal guards stampeding towards him. "Yes?" he asked somewhat bemused. Before he could react, the cell doors vanished and he was flung against the wall and held there by an invisible force. He could see the All-Father with his arm outstretched, hand pointing towards him. "I dare say, that is hardly necessary."

"Quiet boy!" barked the king. Once he was close enough to hold him with his hand and stared right in to his eyes, he continued. "Where are they?"

"Where are who?"

"Do not play games!" the All-Father roared. "All the realms are at risk! Your monstrous spawn have vanished. Not even their corpses remain. And Freya cannot track them. Tell us how you allowed them to escape!" Loki closed his eyes as if he were thinking things over, but it was just to mask his eyes from giving him away, and to hide how they hardened when the man slandered his children. "Well?!"

Loki opened his eyes and glared at the man who was responsible for the hectic rollercoaster that was his life. "I can say with full honesty, that I do not know what you are referring to. If it has dared cross your mind, I have been here for a year, enjoying Asgard's hospitality as always. So, I have no idea how my children escaped-" Which was true, "-nor who freed them-" also (technically) true, "-and my magic has been so restrained I am unable to contact anyone outside the prison block, let alone another realm."

Odin glared at him, trying to discern any falsehood only to snarl when he gained nothing. Letting him drop to the floor where he preceded to massage his neck, he said, "Listen well, Loki. If any evidence is found with your hand in this, the consequences shall be most dire. And not even your mother will save you." So saying, he turned and marched away, the guards behind him.

Thor stayed a moment longer, gazing at his lost brother with sorrow and a sense of betrayal in his eyes. "I'm sorry brother, but we all know the threat they pose. I only hope you are uninvolved as you say." With one last look, the thunder god strode away.

Unnoticed, Loki smiled.

Far from the Nine Realms

Four young men laid unconscious midway up a mountain, the chill wind blowing around them as if in a protective bubble, till it simply ceased. The bite of the wind caused one's eyes to snap open. They were golden, an unusual color. Seeing the bodies near him, he tensed, emitting a low growl. However, he paused, as if surprised by the sound of his own growl. Reacting, he brought a hand up to his throat only to stop and blink at his own appendage. With a startled yip, he fell backwards.

This action shook another of the boys from their slumber. Bigger than the rest by a good foot, at least, he pushed himself onto his hands and knees. Just like the first, he stopped and stared at his arms as though confused. "What?" he asked.

Breaking out of his stupor, the first one stood upright and growled lower than before. "I do not know who you are Asgardian, nor how I am in this form, but now that I am free, I will Never! be chained again!"

Blinking slowly, the second stared at the first revealing milky orbs with a black slit in the middle. "Asgardian?" he rumbled. His voice now mostly cleared from the vestiges of sleep echoed with power. "My father hails from Asgard, tis true, but you'll find no love from me for that wretched place."

The sounds of their voices finally roused the last two. By far, looking the youngest, especially compared to the other two, they resembled teenagers entering the last years of adolescence. One had silky black hair, while the other held flowing silver locks. They locked eyes and the silver one cried out, "NARFI!" He threw himself at the now named Narfi, who tensed at his actions, almost as if he were frozen. Noticing this, the silver haired one started to tear up and only held Narfi tighter. "I'm sorry brother. I'm so sorry. I-I didn't mean to, I swear."

His breaking voice finally got a reaction from the black haired one. Hesitantly, he placed his arms around his brother. "I…I know Vali. But, but-I just…" he trails off not able to continue you anymore.

"Who are you two?' barked the first one, causing the two to jump. Seeing irritated, Vali put himself between his brother and the unknown stranger. The other one, however, looked contemplative.

"I feel as if I should know those names. The ring of something familiar, yet I cannot place where." He glanced at the irritated one, then the boys. "Tell me children, what are your full names." Quickly, the boys seem to become more fearful. Being asked for their full names was being asked to identify their father, something neither was willing to do.

"What about you?" questioned the first, slowly moving himself so that he can keep the three in his line of sight. "You've yet to introduce yourself."

"As have you."

The first one growled in response, before smiling showing a full set of teeth which seemed unusually sharp for a man. "I am Fenrir Lokisson," he proclaimed. Whatever reaction he got, he didn't get it.

The second man blinked at him slowly. "Truly? Well, I am Jormungandr Lokisson."

"You lie!" Howled Fenrir. "My brother was a serpent, not a man."

"And my brother was a mighty wolf who managed to wrestle Tyr to a standstill as just a pup."

Fenrir snarled. "Don't you ever mention that name."

The two glared at each other, each sizing the other up when the wind suffered a change. Nothing major, but it allowed Fenrir to utilize his enhanced senses. The wind had calmed and he could smell the others. Taking an instinctive whiff, he caught a familiar smell, from the other three. The one who claimed to be his brother, smelt of the deep sea. A saltiness that could only be found in the oceans. But it was the other two who truly got his attention. They smelled of old paper, ink, and dried leaves. But under that, they smelled distinctly…

"You two," he addressed, "why is it that I smell my sister on you?" It truly confused him. His sisters smell is so utterly unique that no matter how long apart they have been, he could never forget. But, it wasn't something on could describe. It defied explanation.

The two looked at each other with trepidation, but with the two fearsome men looking at them, they caved. They explained who they were, who their parents were, causing both to blink in shock, and with hesitant speech, what had befallen them.

The time they took to explain allowed Fenrir to cool his heels. He wasn't always so brash, in fact he used to be quite the timid pup, scared of everything and not willing to go outside without his father. But, betrayal can change someone in surprising ways. A part of him resented his father, yet he still missed him terribly. And to hear what had befallen his now youngest brothers and their father caused his heart to ache.

"You're telling the truth," Jormungandr said, looking surprised. He even gave a hollow laugh. "Your tale has sparked my memory. I remember some Asgardians actually came to Midgard and mockingly told me what had happened. I wasn't even sure they were telling me the truth, but I was so enraged that my family suffered once more that I lost all reason. I must have been suppressing it to blot out the pain."

Fenrir sighed. The more this man talked, the more he was convinced he was his brother, but he had to be sure. "If you are indeed my brother, answer these questions. Who was it that sung us to sleep when we were just babes? From oldest to youngest, who did we idolize besides our father? And when we were children, you bit me where?"

"Father. Tyr, Thor, Freya. And your left hindquarters."

Fenrir sighed, finally dropping his guard. "So, it truly is you." Before the young ones could blink, he had disappeared and reappeared in front of Jormungandr, his arms thrown around the larger man. "Brother!" he yelled in joy, picking him up in a bear hug. Setting his brother down, who only seemed amused, he finally looked over his brother as he was in turn examined.

Jormungandr was the biggest of them all, standing a clear head and shoulders over Fenrir, who if one were to ask, stood at the height of 6'2". Yet it seemed Fenrir was built broader. That's not to say Jormungandr was lanky, he just didn't seem to carry as much muscle. Which was ironic as the two's build represented the other. Fenrir's hair was a mottled brown, looking like mud found in a forest, while Jormungandr's was a dark shade of blue/near black, like you would see in the oceans depths before the light halted its reach. Their facial structure also differentiated them. Jormungandr took after his father with his facial bones giving him a natural sophisticated look, while Fenrir's more masculine features made him look like a Wildman. Fenrir was tanned while Jormungandr was pale. The last thing of note were the pair of wolf ears on Fenrir's head.

Satisfied, the two then turned towards their newest brothers. Vali seemed to take after his mother more. Not appearing quite so feminine as to be androgynous but looking like he shouldn't be anywhere near a battlefield. A pretty boy, essentially. Narfi seemed to be a miniaturized version of Loki, but with one key difference. Well, two. First, his eyes were not green like their fathers, they instead silver, like his brothers hair. Second, he did not command the same authority their father did. He seemed skittish, as if he did or said one thing wrong, he would suffer for it, which only made them grit their teeth in silent rage. Both were pale, but not as much as Jormungandr.

All four different and distinct, but each carrying traces of their parentage that you knew them to be brothers, if only by half. Finally, Fenrir asked the question niggling at the back of his mind. "How in the Nine realms did we get hear and transformed like this?"

With all the noise now gone, they could hear the sound of paper flapping against something. Looking, Jormungandr snorted in amusement. "Brother. It seems there is a letter strapped to your back. Reaching behind him, Fenrir tried to grab it only for it to move just out of reach. He tried again only for the same thing to happen. He then began to move in a circle, his attempts to snatch the paper making him look like a dog chasing its own tale. Laughing, Jormungandr grabbed the paper and stopping Fenrir's amusing antics.

He opened it and began to read, his eyebrows rising with every line he crossed. "Well?" huffed Fenrir.

"It seems, Father has made a deal with someone. Someone powerful enough, to break through Asgards defenses, and stealthy enough to be able to avoid Heimdalls all seeing eyes."

"A deal? What was offered?"

"It fails to mention fathers price, but it was enough to find us and free us. Me from Midgard, you from wherever they imprisoned you, and our brothers from our sisters realm." That was impressive and terrifying. "Apparently, though, this being is as much a trickster as Father as the instructions for us are to do whatever we wish for as long as he can find it amusing."

"Did it mention why we are transformed."

Jormungandr nodded. "It says, 'I have given you these forms as a giant wolf, an even larger snake, and two ghosts would be hard to ignore even for the locals of this planet'. There's even a Post Scriptum. It says, 'Welcome to Remnant'."

"So, we can do whatever we desire?"

"Apparently."

"No consequences?"

"I'm sure the locals will try their best."

"And we never have to deal with Asgard?"

"Only until we are summoned for something unspecified."

Fenrir grinned. Jormungandr grinned. Even Vali and Narfi managed to smile. "I can live with that."

AN: For any of you wondering, this is up for grabs, though I would appreciate if you would mention where you go the idea from in any AN you make in your story. There will be more to come as this isn't the only idea I have. Till then!
