Introduction: This story is created using the prompt njchrispatrick provided in chapter 4 of the story A Happy Accident: 70 Years. It goes as follows:

"Loki gets turned into a baby human female and has his memory wiped to learn a lesson after he constantly seduces Aesir men. His new name is Lily Potter. Thor decides to take a jaunt down to Earth while his brother is under punishment. Unfortunately, he does not know what Loki looks like, and decides to use the rest of his free time with the beautiful redheaded woman drinking alone. Lily's boy is born with golden blonde hair and glowing green eyes placed on a face that was much too masculine to have been James's. To keep James from knowing she disguises the baby to look like him. What happens when, over a decade later, the truth is revealed?"

I know two stories on this prompt already have been posted, but this is my take. I hope you'll enjoy reading!

Living out a life as a human is a common punishment on Asgard. Loki is being punished; he remembers nothing of his life, thinking that his name is Lily. Lily's marriage becomes strained when she cannot have children, however she meets a tall blond man and one unplanned night later everything changes. This is the story of what happens years later when Loki wakes up in his own body.

Conceiving the Impossible

Chapter 1
Words: 3 643

Loki woke from slumber. He blinked his eyes and saw the contours of his chamber coming into focus. It was normal. It was boring. Perhaps it was comforting. He rose languidly, stretching and flexing his muscles. He got to his feet, splashed cold water on his face from the bowl that servants had prepared for him.

After using a soft towel to pat away the water he regarded his reflection in the mirror and when he saw his face he stiffened. He didn't look any different, he knew that intellectually. He still had pale skin and chiselled features, dark hair and green-blue eyes. Yet, it was all wrong.

He remembered his father's words then, hearing them spoken in his head. "If you continue to insist on constantly taking the appearance of women, using the form to seduce good men, you need to learn what it truly means to be a woman. Perhaps then, you will understand and honour them and stop with this nonsense."

He had been sent away. He had lived a different life. As a woman. A mortal woman. It never ceased to astonish him how Odin could preach that the people of Midgard were their equals and at the same time use them for lessons and punishments, as if they existed simply for the purpose of educating their betters.

Though perhaps having them be teachers spoke of him honouring and respecting them. They lived shorter, more intense life, having to experience everything in a fraction of the years the Aesir had at their disposal. Living like them could therefore teach much more than any punishment set in Asgard could.

Lily Evans, had been his name. A girl with dark red hair and green eyes. A witch. Magic had not been taken from him even during the punishment. It had been a good life. School and friends and magic. And love too. Lily Evans married Potter. "James," he whispered, remembering with sorrow how he had heard him die by Voldemort's wand. And then… "Harry!"

He began to search for clothes. He needed to get back. He needed to get back to his baby. The next thought stopped him as he was pushing his arm through the sleeve of his robe. "Thor," he whispered, eyes widening in a manner that would be comical had his face not also turned ghostly white. "Damn him!" He was filled with absolute horror at what had happened. "Oh, fuck!" He straightened his grab and exited his chambers at a half run. He knew time must have passed. It always went a long time before anyone who lived out the full life of a human settled back into their own body. He could only hope that not too long had passed. Not that it mattered. Thor would be made aware of his blunder. Of what had…he swallowed down bile that threatened to spill up his throat… his brother would know what had happened between them.

"Where can I find my brother?" he asked of a guard stationed not far from his rooms, he noticed that his voice was a croak, but he couldn't make himself care even as the guard frowned at him.

"In the courtyard, my Lord," the man said slowly. "The King and Queen will be pleased to hear that you have awoken," he added hesitantly.

"I'm sure they will be," he said with a half-sneer-half-smile. There had been no mention of a son, no mention of Harry being happy to hear that he was once more among them. This could mean either that Harry was dead- yes he could think it, even if it hurt, it wouldn't be very surprising - or that his family who must know, had not cared to interfere and bring him home. Neither thought was pleasant.

He was in a hurry and did not care for decorum or to diminish his abilities to keep people comfortable and as soon as he had rounded a corner he gathered his magic and transported himself to the courtyard. There were protections against such magic, but he had an advantage in having learnt the way to travel instantly from the magical humans and in their never ending arrogance the rulers of Asgard had not accounted for such magic. He passed freely though the protections appearing at Thor's side. The blond warrior was sparring with the Lady Sif.

"Excuse me, My Lady," Loki said with a small bow, trying to keep himself together by once more reverting to being courteous, or perhaps he only did it because she was Lady Sif, and he didn't have any qualms with her. "But I shall need to borrow this dim-witted oaf."

"Loki?" Sif said in surprise, stopping her double bladed sword a handbreadth from his face, as her reflexes had made her attack at his abrupt arrival.

"Brother!" Thor crowed in delight, slapping Loki on the back. "You have finally awoken!"

Sneering Loki turned around and punched him, he wanted to do more, but one hit in the jaw would have to do for now. "You absolute bumbling idiot!" he yelled hotly.

Thor's smile ran off his face and he looked perplexed. "What have I done?" he asked, more solemnly, rubbing at his chin, surprised at the hit rather than hurt by it.

"Oh, you have no idea, do you?" Loki laughed hollowly, perhaps a bit hysterically.

"No, I confess I do not."

The warriors who had been training in the courtyard had all stopped their drills and sparring to regard the two royal siblings; Loki looked them over and remembered that they were not in private. "This is not something everyone needs to hear. Lady Sif, by your leave."

The woman nodded. That was what Loki liked about her, she was a no nonsense sort of person. She had to be, to compete with the men who wouldn't accept her if she was anything less than perfect.

Loki grabbed onto Thor's arm and apparated them back to his chambers. He saw with glee that the blond stumbled as they landed and looked faintly ill.

"What was that?" he asked in a groan and quickly sought a place to sit down.

"A trick I learned in my absence. Now I need you to tell me how many years have passed since my banishment."

"Thirty? Forty? I'm not certain, years pass quickly," Thor said, massaging his temples. "That trick was truly cruel, brother."

"Are you truly this stupid? Are you too much of a bumbling idiot to even keep track of time?"

"What does it matter?"

"Truly you must know that humans live longer than that. I died young. I left people behind. People I care about. People who are important to me." Loki drew in a deep breath. "A child."

Thor looked up abruptly, his eyes large. "A child? But the spell, it would not let you conceive a child with a mortal."

Loki laughed. "And it didn't." He changed his appearance, shrinking in height, his body getting curves and his hair turning auburn, his clothing shrinking to fit his new body. "Do you see now?" he asked, his voice soft and feminine, mocking and hysterical and so much more all at once. "Do you understand what we- what you have done?"

- Conceiving the Impossible-

Thor would never have thought that he would miss his brother. It was true that they were family and that they shared a bond, but they had never been close as they couldn't understand each other. Much of the blame lay on his shoulders, he knew this but it was only in recent years that he had begun to become aware of it.

It had been a fight where they as usual were of different opinions, and they had gone their separate ways. Both had failed to complete the task that was set, and then as they were forced to work together they had at last succeeded. It had opened his eyes to his brother's good qualities. They had gotten friendlier after that. But enough that he would miss Loki after only a couple of decades? He hadn't thought so.

He had come to miss his brother's wit and remarks dripping with acid. He missed the adventures they had gone on together. The Warriors Three and Lady Sif were good companions, but Loki added something to their ensemble that he found himself longing for. A human life is short, and from the perspective of those who live for thousands of years even more so, yet he found that if he had the option he would want to meet Loki now and not in a century's time.

As a way to feel closer to his brother in spirit he travelled to earth.

The society of Midgard had changed a lot since he last visited. That had been several hundred years before and it hadn't occurred to him that the people of Midgard would evolve so much. In Asgard things rarely changed and in his experience the same was true for Earth, but now they had vehicles that moved at velocities that could rival the battle ships of Asgard, buildings that were as tall as the Royal Palace and there were lights everywhere. It was strange and it was fascinating. It took him some time before he was able to walk among them without drawing attention for his strange appearance, foreign mannerisms and archaic speech.

On the eve of the last day he had planned for his visit to Midgard, Thor ventured to the lands he had most often visited during the days when it was common for the people of Asgard to journey to Earth. Though things had changed in this land as well it was possible to find places where people chose to remember the old, and it was in such an establishment he retired for the evening to drink and seep in the atmosphere.

The air was filled with the smoke of a fire over which a whole suckling pig was being roasted. The walls and ceiling were made out of large wooden logs, the beams of the construction visible and carved with different figures of beast and man.

He looked around and his gaze fell on a woman who was sitting by the bar, nursing a near empty tankard of what may either be mead or bear, depending on how far the establishment had gone in trying to recreate the days long since past. From where he stood by the entrance he could only see that she was small and that she had hair the colour of a deep sunset falling in soft ringlets down to her shoulder blades.

He approached the bar and took the stool next to her. From his new position he could see her face and it did not make him regret his decision to approach her. She was beautiful with soft, symmetrical features and green eyes. She did not appear to be happy however, looking down into her drink as if searching for answers in the golden-brown liquid.

"God kveld," he said softly, politely.

"I'm sorry, I don't speak Norwegian," she replied without looking up, "and I'm not interested."

"English is it?" Thor asked.

Now she looked at him and he felt the impact of her eyes. They were even greener than he had first thought. "Oh," she breathed softly. "I..." Her face had taken on a pensive look as she regarded him, eyes narrowed and brows furrowed. "I feel like I know you from somewhere."

"That couldn't be, I would remember beauty such as yours."

Her lips twitched into a reluctant smile. "Not interested, remember?" She held up her left hand and he could see the golden wedding band that sat there.

He inclined his head, admitting defeat. "I see. What I don't see however is a reason to not share a drink as friends."

She gave him an incredulous look. "Really? Were you not looking for a conquest? A partner for the night?"

Thor shrugged his large shoulders. "I am leaving for my home tomorrow and I wished to spend one last night enjoying myself, I had given little thought to if the night would end early or late. I saw you sitting here alone and chose to seek your company; no one should have to drink alone. If you simply wish me to sit here silently I will do so. If you wish to talk, I'll listen. If you want to hear stories to keep from thinking of whatever sorrows you hold, I can provide too. If you had wanted more I would have been honoured. Simply allow me to spare you loneliness tonight."

All hostility had melted away from her countenance as he spoke. It left a small spark of gratefulness and hope, greatly tempered by desolation and sorrow. "Lily," she said holding out her right hand for him to shake.

He took it, but did not shake as was the contemporary custom on Midgard, instead bringing it up to his lips and placing a small kiss on the knuckles. "Lady Lily," he murmured as she blushed lightly. "I am Tor." That was the name he had used since he better came to understand Midgard. It was a common enough name in the lands he had visited in his youth, a variation of his name to reflect the languages spoken in the region where they had once worshipped the people of Asgard, he had thought it fitting.

"As the Norse God of Thunder," she said.

He simply smiled brilliantly, but did not comment on it. "Let me provide you with a new drink."

"Okay."

- Conceiving the Impossible-

They had shared on drink which became two and three. In the beginning Thor talked about his travels around the world and that he missed his brother who he said was gone without specifying anything. And when they became more comfortable with each other Lily told him what she was doing there. She had been in a fight with her husband because the doctors had said that she was unable to have a child. They were both disappointed. They had wanted a family together. She felt like she had let him down. Her husband, James, was from an old family and though he claimed that it didn't matter, the idea that his line wouldn't be continued because he had fallen for an infertile woman, pained him. He had not said a single cruel world to her, he had assured her that he loved her as much now as he always had and that he didn't regret marrying her. He had assured her that he would do it all over again even knowing. However for all his words and all his kindness the sorrow she could see in his eyes was coming between them.

Lily didn't know what to do. She thought about divorcing him so that he could be free to search for another woman to love, a woman who could give him a child. After a month of living together, everything continuing as it had been before but feeling hollow, Lily had said that she would travel for a bit, just for a few days or so. She had told him frankly that she had to think about what to do now, she had to be sure that this wouldn't come between them, that they could still be happy without being able to have a child. Some time apart to think would do them good. She had arrived in Norway the very same day and she felt tired of it all and more alone than she had imagined. She missed James and she said that perhaps that was her answer.

Thor hadn't meant to do it and Lily had started their acquaintance by saying that she wasn't interested, but he felt the need to comfort her somehow and a kiss that was aimed at her cheek had ended up on her mouth. It created a spark between them, two strangers who had been drinking together and sharing their stories.

Thor drew back, looking at her, hesitantly, wondering if he should apologize.

She looked conflicted, though not angry. "We can't," she whispered. "We absolutely can't."

"Then we don't," he answered easily.

"You feel familiar somehow," she said for a second time. "I feel like I know you. But we truly mustn't." Still she pressed her lips against his again as if drawn there.

"It's okay. I'll take no more than you want to give."

"No, you must stop this now. There is something about you…"

"It will be okay."

In the end she had given everything, perhaps just because he hadn't asked anything of her. She was gone when he woke up in the morning, her scent still lingering in his bed sheets. Thor had spared her a last thought, hoping that things would go well for her then he had returned to Asgard his longing for his brother soothed.

- Conceiving the Impossible-

"Norns have mercy," Thor whispered. He had turned frighteningly pale. "Lily. You were Lily." He looked at his brother in the form of the woman he had spent one night with. Now he had his answer to what had become of her. The spell their father had placed on Loki so that he would not have a child and form any attachments that would follow him into his ordinary life had been the reason why Lily could not have a child with her husband. And soon after their meeting she must have died. It was also the reason why she had insisted that she knew him, even if he could not recognize her.

"I am," Loki said shifting back to his own form.

Thor swallowed. "We… I… we had… I sle-"

"Yes, you big baby, we had sex."

"It's wrong! We are brothers!"

"Yes, it is wrong and believe me when I say that I draw no more pleasure from remembering what happened than you do."

"So I didn't pleasure-"

"Don't you dare make this about your pride! I suggest that we agree on never speaking about that evening again." Loki waited for Thor to nod. "What is much more important is that I, as Lily, had a child by you." He laughed hollowly at how absurd the notion was.

"We have a child?"

"Yes. A son who I named Harry. I died to protect him and now you and I are going to demand answers from our father regarding what became of him."

Thor looked pained.

"What?" Loki demanded.

"Father has entered the Odin sleep. He will not be available ere the morrow."

"Let us see Heimdall then, he will be able to tell me where my-"

"Our," Thor butted in.

"-son is. If he is alive and well."

"Why wouldn't he be alive?" Thor asked with concern, flinching when Loki grasped his arm once more and the world twisted around them.

"Weren't you listing?" Loki snarled, uncaring about the fact that Thor's complexion had turned slightly green after they'd apparated again. "I told you that I died to protect him, of course he would be in danger."

"Sorry," Thor mumbled, closing his mouth soon again as to not let anything unwanted, both insults and bile, escape up his throat and out past his lips.

"Heimdall," Loki called, walking into the observatory with a determined stride.

"I know why you have come," the Gate Keeper said calmly, turning around on the dais he was standing on.

"Then this should be quick. I shall not ask you about my father's intentions; I will want to hear them from him. So I ask you what's befallen my son. Is he alive? Is he well?"

"He is alive," replied Heimdall. "And he is well considering."

"What?"

"After the death of your incarnation as Lily Potter, the dark lord Voldemort tried to kill him, he could not. Your sacrifice had left him with protection and the curse designed to destroy lives rebounded, his Asgardian blood also protected him."

"Is Voldemort gone then?"

"Alas, no. He was too deeply emerged into the darkest of magicks to die a normal death. His spirit remains and is ever searching for a way to return."

"I see, he shall have to be dealt with then. And Harry, what happened to him after?"

"He was placed with Petunia Dursley by Albus Dumbledore."

"Excuse me?" Loki said in a deadpan. "I couldn't possibly have heard you right. He would never place Harry with Petunia. No one in their right mind would place a magical child with my sister."

"Sister?" Thor said.

"Not now, Thor," he brushed away the inquiry.

"That is nevertheless what happened."

"If she has hurt him, I will hurt her."

Heimdal's countenance was grim.

"She did," Loki concluded.

"She had not been a loving or just guardian."

"What is the year?"

"Today it is the fifth of November 1995."

"Will I find him at Hogwarts?"

"You will."

"Open the gate, we are going."

"As you wish."

"Loki, do you believe this to be the wisest cause of action? It's hasty, and unlike you," Thor said, holding onto his brother's arm.

"Yes, it should be you who wished to go, yet I see that's not the case. Do you regret the outcome of that night then? Would you like to pretend that there was no outcome, same as I've claimed that we shall never discuss what we did for Harry to be born?"

"It's complicated, you've expressed this yourself. I would like to meet him, but it should be done right."

"The right thing would have been for me to wake up much sooner. I will not delay this. Come with me or not, I do not care." Loki twitched free and approached the portal that had been opened by Heimdall.

"I will come. He should meet us both," Thor insisted.

Loki smiled thinly. "Good."

End Chapter 1

AN 7th June 2014:

The only thing I didn't enjoy about this prompt was how Lily cheated on James, and I'm not completely pleased with how I handled it, still I tried to make her as sympathetic as possible, and we'll get to see what Lily/Loki thought that night a bit more closely at a later point. As I said in the introduction, this prompt has spawned to additional stories and I recommend that you look at them too. They are A Case of Mistaken Identities by savya398 and Seidr Legacy by Coho Commanche.

In any case I enjoyed writing this chapter a lot, there will be more to come, though I don't dare say when.
