Set after Thor: The Dark World... There will be spoilers.
I started this story with the idea that "the Avengers need help from the one person that cannot help them. Loki. So Thor brings the one person who knew Loki best, his wife Sigyn. Only to find out that Loki is not as they thought he was." But then the story decided to go it's own way, and I have no idea what is going to happen. Right now it is a bunch of back story and character development for Loki and Sigyn. I completely cut the Avengers out.
I imagine Sigyn looking like the cover picture, a brunette Amanda Seyfreid. I originally had her eyes as golden, but after looking at the picture a little more, I think I like them that silvery blue color.
There will be flashbacks and Loki will be a little ooc in his younger self, Pre-first Thor movie and childhood. There isn't much known about Sigyn, so I will use what I know and try to make well-informed deductions and creative links. Let me know your thoughts. Sigyn might start out a little meek, but... Hell, she is married to Loki. You don't think he would marry a meek little mouse do you? Give her a little time to grow if you think she is a little washed out. If you google Sigyn there are all kinds of theories about her and ideas, but I found a really cool website that talks about her hidden strength, and I'm going to try and focus on that type of interpretation.
##############Whatever our souls are made of, his and mine are the same.#####################
Sigyn walked through the gates of the palace. Called to the hall of the All-Father for an audience with Odin. She had come from the country estate she had been living in for the past 4 years. Since Loki's betrayal of Asgard, she had exiled her self to the home. This was her first time in the capitol city since then, even when Loki had been imprisoned, she had not set foot through the golden walls nor laid eyes on the palace.
Now she felt the eyes of the All-Father's court on her, watching her. It was as if blood were on the snow and the wolves were circling. After her husband's actions, no one trusted her. The only one who had, Frigga, had died only days earlier in the attack. Sigyn was truly alone now.
Standing before the large double doors, refusing to sit as small groups walked past, whispering behind their hands while their eyes traveled over her, Sigyn thought of Loki. And how things had been.
Sigyn stood the grass of the royal courtyard, blades tickling her feet and strands of a weeping willow stroking her hair as she looked at the sky. There was a sound, and she turned. Loki sat on the stone bannister of the veranda, watching her.
"My Lord," She laughed, moving out from the curtain of the willow. "How long have you been there?"
"Long enough to gaze on your thighs." He smirked, giving his characteristic crooked answer. He must have been watching her since she took off her shoes.
Shaking her head in amusement, she stopped on the grass once she was out of the tree's embrace.
His eyebrows rose. "Will you not come to me, My Lady?"
"I will not, My Prince." She turned away from him, tucking a curl behind her ear before holding her hands behind her back, strolling slowly down a path.
She missed the determined look on his face when he slid off the banister and strode toward her. He was quickly next to her, mimicking her pose and pace as they walked the gardens. "Lovely Sigyn, when shall we marry?"
She laughed, her face thrown up to the sun. "Your flattery is appreciated, My Lord, but we will never wed. I am betrothed to Theoric(*1), and we will marry once he returns from war."
He shook his head in disappointment. "If he had twice his own intelligence he still would not be worthy of you." He caught her hand, making them both stop on the path. Loki brought her hand to his lips but didn't kiss it, instead letting his next words wash over her skin. "I would have married you and never left your side." Finally his lips touched her smooth skin, brushing back and forth in a non-traditional kiss.
Sigyn's breath caught in her throat. Suddenly the distance between them seemed too small, as if his green eyes were pulling her silver ones in.
"Sigyn!" Frigga's voice cut through the tension between them and Loki dropped her hand while she took a step back out of propriety.
"I am here, My Queen." Sigyn's voice was light as she caught her breath, moving towards the queen.
"Oh, yes. Loki, what a surprise to find you here in this sedate setting. Shouldn't you be causing trouble with Thor?" Frigga tucked Sigyn's hand into her elbow, patting it in a motherly gesture. "Come along, dear, we must get to your lesson."
Sigyn nodded, but before they could step away, Loki caught a curl of her hair, twisting it around his finger. "Until we meet again, my lovely Sigyn, I shall be thinking of ways to sway you."
"Your pardon, My Prince, but I will not be swayed from my commitments." She tugged away from him and continued to her lesson with the queen.
True to his word, that hadn't been the last time Loki tried to woo her from her betrothed. Then they received word from the battle lines that Theoric had died, and Sigyn mourned for months. When she finally returned to court, Loki redoubled his efforts to cultivate her affections. Successfully.
"Why do you want me for your wife?" Sigyn posed the question coyly, brushing a soft petaled flower against her neck as she looked out over the sea. She sat on the beach below the rainbow bridge, her bare feet partially sunk in the sand.
Loki lay in the sand near her, lounging like a hedonistic roman statesman, propped on one elbow. "I find you to be many things; intelligent, clever..."
She laughed. "Those are the same thing, My Prince!"
"I disagree. Intelligence is knowledge, cleverness is the ability to use knowledge." He shrugged before giving her a wink. "You are beautiful and protective of those you love. You are also witty, and I find you amusing. You are kind and truthful, and have never thought of me as second to Thor."
"Why would I think you second to Thor?" And he loved her all over again. She couldn't even comprehend people thinking of him as a replacement should anything happen. Thor was not first in her heart, and nothing she did was in pursuit of him.
He sat up and took the flower from her hand. Silently casting a simple spell, he tapped it on her nose, making small golden lights shower over her face and catch in her hair, leaving tiny glowing sparkles. She laughed again, and when she looked at him again he was sitting facing her, legs folded next to her, with one arm stretched over her legs and braced on the other side of her. His hand palmed her cheek and her breath caught as his face hovered only inches away.
"My Lord?"
He grinned wolfishly. "I will have you say my name before I kiss you."
Her voice dropped to a whisper, as if they were sharing a secret. "And if I do not?"
"Then I will enthrall you until you shout to all of Asgard that you are mine." He inched closer, his strong nose brushing hers.
"Do you think you are capable of that, My Prince?" Her voice taunted him with the unspoken refusal to say his name.
He smirked. "That and more, sweet Sigyn."
"What shall I say?" She whispered as his mouth hovered less than an inch from her skin.
Using his grip on her jaw, he turned her head slightly, moving his mouth down her neck, not close enough to touch but close enough for her to sense him on her skin. "Say you will wed me. Say you will romp in my bed and carry my children." He exhaled on the skin joining her neck and shoulder, inhaling as he traveled back up again. "Say nothing but my name and I will worship you."
"My Prince..."
His mouth hovered over hers again, and she tilted her chin up, but he grinned and avoided her. "Say my name."
Sigyn licked her lips, watching Loki's eyes darken. She had some sort of feminine power over him, and as much as she wanted to experiment with it, he also had power over her. "My Lord Loki..."
She lifted her mouth to him, compliant for his kiss, but his jaw clenched and he denied her again. "Just my name Sigyn. I may set Asgard ablaze if you do not." His green eyes were glowing brighter than the bifrost with their heat.
"My..." She swallowed, licking her lips again, making him growl in warning. "My... Loki."
Suddenly he was kissing her, her hands coming up to cup the sides of his jaw as he slanted his mouth over hers. "Your Loki. I like that." He nudged her face with his, tilting her mouth up as he laid her down in the sand.
One of his hands settled on her waist, while the other propped her head out of the sand. Nibbling her lips, Loki trailed kisses over her cheek and down her neck. Her back arched and he groaned against her collar bone.
The sound of a large carriage rattled nearby, the sound jolting her and she scrambled out of his grasp. He jumped up to follow her but she held out a hand in warning. They stood on the beach, a few strides from each other. "My Lord, if we are caught in this manner..."
He grinned. "Then you would have to marry me."
Judging by her expression that was the wrong answer. "I must return home, My Prince." She grabbed her shoes and ran down the beach, faster than he had thought she could.
That was their first kiss, but not their last. It soon became common for them to sneak out together after dark. Their relationship was secret for months until she agreed to wed him. Asgard was shocked when it was announced. The speed of the nuptials had everyone convinced that she must have been pregnant.
Finally the guards opened the doors and she walked confidently through the almost empty room. Reaching the edge of the platform, she spread her skirt while dropping into a deep curtsy, averting her eyes in deference.
Odin said nothing until the guards closed the doors and they were left alone. "Lady Sigyn, you are more lovely than last I saw you."
"Thank you, My King." Her head remained bowed, awaiting his permission to rise.
Loki looked down at the young woman in front of him. He had waited a long time to hear her call him 'Her King.' She was more beautiful than ever, her curling mahogany hair had become longer and richer in the intervening years. Her body had filled out from the Asgardian form of puberty, and unlike many of the women in court, she was hourglass shaped rather than straight and thin. She was graceful, with long limbs and a presence that always brought him a feeling of calm. Even now she held the curtsy without wavering.
"You may rise." Loki was disappointed that he had to wear the illusion of his father to see her like this. If Odin had given him the throne from the beginning, Loki would have had Sigyn call him king a thousand times in a thousand different positions. Oh, how he would have her cry out for him. He still desired her with all the strength of his youthful passions, and loved her with the new appreciation of a wiser heart. He would have had his own princes and princesses from her body by now. Another reason to curse Odin.
"Do you know why you have been called here?" Odin's voice echoed through the chamber.
She still would not meet his eyes, which chafed him. "No, My Lord." He wanted to see her silver eyes looking up at him.
"You never visited your husband while he was imprisoned here." Loki hadn't meant to say that. But now that he had, he wanted to know. He turned away from her to look out the large windows. "Were you so fickle in your devotion?"
He could see the confusion on her face, her answer slow and thoughtful. "No, My King. I did not think it wise to visit. Loki betrayed Asgard. Many thought me an accomplice to his plans, and attempts were made on my life. I had to move from the city for my own protection. My Queen Frigga..."
Her words brought Odin's head around quickly. People had tried to kill his wife? For his crimes? Her hesitation over his mother's name... "Continue."
"I will not betray My Lady's confidences, nor think ill of her. I trust she told you of our contacts and did what she thought best." Her voice was soft but firm, unwavering in her devotion to Frigga, but still not confronting her king.
Loki's mind whirled. His mother had not delivered any messages from his wife. Why? To protect him or to protect Sigyn? "I knew of your communications, but not of their content. I'm sorry that I did not question her further, but... Please. Tell me of what you and my wife spoke, as I cannot ask her myself." Sigyn and Frigga's affection for each other was a secret from no one, so it was easy to play upon her loyalties to his mother and her grief over her death.
She hesitated, but eventually spoke. "My Lady Queen said that she would deliver my messages to my husband. I conveyed several to her though our communications. I sent news, my love, and... The words of a wife to her husband. For my own safety, I had to remain in Bredablik(*2)." Loki thought of the shining palace that he had built for them, and the plans they both had.
Loki's forearm was pressed firmly in the small of Sigyn's back with his hand splayed possessively over her hip, holding her body tight to his, while his other hand cradled her head. His long fingers were threaded through her hair, her willingly following his guide so that he could plunder her mouth. Her arms were wrapped around his shoulders, one palm on the bare skin of his neck while the other gripped and tugged at the shoulder of his armor.
Odin and Frigga stood in front of them, sharing a look of indulgence for the newlyweds. Meanwhile Thor shifted uncomfortably on his feet, along with Sif, Fandrel, Volstagg, Hogun, and Tyr. Finally, when it seemed the newlyweds would not separate, Odin cleared his throat. Loki broke contact for the briefest of seconds, his eyes taking in the discomfort of the others.
With a sly smile he returned to the lips of his bride, eyes closing in pleasure. While the others watched, magic swirled around them. Within seconds, Loki had transported himself and his bride to Bredablik. A shining palace that he commissioned the moment he convinced her to be his wife. He designed the entire place with her in mind, and the bedroom they appeared in was no different.
Cream and ivory linens, furs, and silks covered nearly every surface, from the large canopied bed with silver etchings in the ebony headboard, the floor to ceiling curtains and drapes, to the large chaise with silver embroidery. The plush rugs made of the softest furs caressed their feet and the softly scented breeze shifting their clothes reminded him that he wanted her naked beneath him.
Her nails scraped along the neck of his armor, and he hissed, green eyes flashing open to stare into her bright silver eyes that were dilated with arousal. He would have her tonight, and judging from her response to the thrust of his hips, she was going to have him as well. They had waited for this moment, Loki's love and respect for her outweighing his passion, only barely enough to last him through the quick engagement.
"My Lady Queen told me that..." She hesitated again, though not out of protection of his mother. She was choosing her words. "That Loki was not well. He would not accept the comfort or advice that she offered him. My Queen said that he would not benefit from my presence and... He would use his words to hurt me. My Queen wanted to spare me that pain and I allowed her to take the burden alone when I should have... I should have taken care of Loki and lightened her heart."
He was jolted from his memories before his illusion started to suffer and Loki stared at her through Odin's eyes. She was telling the truth. Sigyn always was so innocently truthful. "In these years you have remained loyal to Loki?"
"Of course, My King." Loki's eyes went to her hand, searching for the ring he had given her. It was there. The black star-sapphire surrounded by diamonds in a white band sat on her finger, loose as if she had lost weight since he last saw her.
"Walk with me." Odin stepped down from his throne platform, striding to her then motioning her to walk next to him. They crossed to the balcony and began walking the long marble path around the throne room. It was time to do what he had brought her here for.
"Loki is dead." He watched her face as he said it, but her laughter made him scowl.
His scowl must have transferred to the illusion because she stopped. "I'm sorry my Lord, but I do not understand. I thought you spoke in jest."
"Thor took Loki to the Dark World to save Asgard. He died in battle, and has been forgiven for his crimes due to his heroic actions."
She was silent for a long time. Then she moved to the edge of the bannister and stared out over the city, hands placed calmly on the cool stone. "Odin All-Father... I do not wish to offend you," Loki internally flinched at being called by his false father's name. "But, Loki is not dead."
Loki stared at her, pausing to formulate his response. Did she truly know him so well that she could guess his movements? Know that he wouldn't allow himself to be killed on some far away planet and that it was all a ruse? "What do you mean?"
He stood next to her, looking at her profile as she stared at the sky. Her hair was swept back from her face with braids to cascade down her back and the skin over her cheekbones took the light like polished ivory.
"I have known Loki since we were children. I knew him again in adolescence when we shared the learning of Lady Frigga's magic." She sighed, tilting her head and Loki watched a small curl fall over her forehead.
"And then we were separated. After a long time apart, we returned to find each other grown, and with a deep link to each other. When we wed, our connection was seared into us. I would know if he had died." She met his eyes for the first time that day and smiled. "I would have felt as if my heart were ripped from my body as the connection vanished." She ducked her head almost bashfully, but there was a hint of resignation. "I can still feel him."
Loki felt the air get sucked out of him as his vision tunneled on her. "You can tell no one of this. Do you understand? I must speak with others, and send out a search party for his body." His voice was desperate, she must never tell anyone that he was alive.
"Of course." She nodded. "When you find him, what will happen to him? Will he be imprisoned again?"
"No." He could not tell her his real plan, to take the throne, but he needed to tell her something. "Thor does not want the throne, but I cannot allow Loki the position. He has been absolved of his crimes but the people still hold him responsible. He must be given time to change. To convince the people that he is worthy. For now, nothing is certain."
She nodded. After a few more minutes, they returned to the throne room, Loki as Odin dismissed Sigyn, and returned to the royal chambers. He spent the next few days deep in thought.
#########################################################
Theoric was killed by Loki in the Marvel info I found online. I prefer to write it as he made sure that Theoric's commander kept him in the field of battle, giving him time to woo Sygyn, instead of actively killing him. Theoric just so happened to die.
Bredablik was actually a palace belonging to Balder, Odin's secret son and Thor's half brother(in real mythology, not Marvel mythology). I stole it for Loki.
