Author's Note: Alas I should have put this in the first chapter, but mistakes happen. Needless to say the first chapter is a play on a deleted scene from Thor. I obviously took my own artistic liberty with the scene, and you can expect that throughout the rest of the story. I will not change events that are cannon per say, but since we are not 100% sure what will happen during Thor: Dark World, Captain America: The Winter Soldier, etc. I am taking a few liberties. As for the disclaimer: I own nothing. Sigyn is an adaptation of the one found in Norse Mythology, not Marvel. In fact I don't know anything about her Marvel counterpart. The rating is 'M' for violence, torture, and suggestions of sexual situations. The word 'damn' will pop up two or three times, but that is the only language you will find. Well that takes care of the housekeeping issues. Enjoy!
Sigyn left Loki and Thor, and after glancing around to make sure no one was present, she teleported herself to the spot where she would watch the coronation. Loki had addressed the spot as being in the rafters, but that was not truly accurate. The spot was actually a small ledge that was large enough to fit all three siblings when they were younger, but would probably only be large enough for Sigyn now. She sat on the ledge and swung her feet over so they were dangling in the air. The noise of the crowd was deafening. It seemed that the entire city of Asgard was in attendance for the coronation. Sigyn let her gaze wander to the throne where the AllFather sat. He was wearing his full amour just as Thor and Loki were earlier. Sigyn's mother, Frigga, stood on the top step to Odin's right. The Warriors Three stood on the steps to Odin's left. Loki stood on the step below Frigga, and Lady Sif was on the step below Loki.
Loki glanced up to the spot where he knew Sigyn was sitting. Though he couldn't see her, his magic told him it was because she had veiled herself from prying eyes. He threw a knowing smile in her direction before the crowd's roar caused him to turn his gaze towards Thor, who was making his way down the length of the great hall. Thor's antics as he approached the throne caused Loki to roll his eyes, and he imagined that a look of distaste was probably plastered on his face. While Loki loved Thor, he could not approve of his ridiculous behavior. This was not the way a king should conduct himself…
Sigyn noticed Loki looking up at her, and she blushed. She knew that he couldn't see her, but somehow he always managed to sense where she was. A sudden cheerful outburst from the crowd told Sigyn that Thor had finally made his appearance. She quickly turned to face him, and she couldn't help but shake her head at his childish behavior. You would have thought that he was drunk at some lavish banquet, not being handed the throne of Asgard. Despite his childish flaws Sigyn knew that Thor had the potential to be a great king, but part of her still questioned the AllFather's decision to hand him the throne so soon. As she watched her eldest half-brother kneel before the throne she shook her doubts away. Odin always seemed to have a reason for his actions so surely he wouldn't crown Thor before he was ready…would he? Even the AllFather could make mistakes…
As Thor began to take his oaths Sigyn glanced at Loki. Despite his best efforts, Loki looked downcast. It was a look that she had seen over and over again through the centuries, and it broke her heart. Loki always knew that the throne would go to Thor, and he had admitted to her more than once that the throne was never something he really desired. Thor was the eldest son so it was only right in the eyes of society that he should succeed Odin as king. Loki understood that, but Sigyn knew that that knowledge could not dispel the fact that Loki felt pushed aside yet again. It was difficult for Loki; he was not the typical Asagardian. His dark hair, lean frame, and striking green eyes stood in contrast to the normal appearance of the Æsir. If his looks were not enough to set him apart, than his brooding personality, affinity for magic, and soothsaying were. Loki was respected, if not feared, by many, but all of the glory and honor went to Thor. Sigyn knew that Loki had saved Thor in battle more often than Thor had saved Loki, but Thor's acts of physical valor always overshadowed Loki's instinctive thinking. It was obvious to Sigyn that Loki craved equality with Thor in the eyes of Asgard, and most of all, Odin. Though it was probably of little consolation to Loki, Sigyn had always seen him as Thor's equal. It was his differences that drew her to him. Loki was one of the few people who understood the struggle Sigyn faced with her own differences, and for that reason she had always been closer to him.
Sigyn refocused on Thor as he took his final vows. Just as Odin was about to pronounce Thor king, he froze. Sigyn looked at the AllFather in concern. Was he about to fall into the Odinsleep? Her heart rate began to quicken as Odin's lips moved, forming words that she could not hear from her spot high above the crowd. Whatever he had whispered sent the crowd into a flurry. People where running in all directions and Thor was rushing out behind Odin. Sigyn felt a hand grasp her shoulder causing her to lose her balance. She quickly lifted her concealing spell, and an arm shot around her waist catching her before she could fall off of her precarious perch. Sigyn immediately recognized the arm that caught her as Loki's, and she assumed he had teleported to her spot to tell her what in Odin's name was going on.
Loki hadn't been able to see Sigyn when he reached the spot where he knew she was sitting, and in his attempt to grab her hidden form, he had almost knocked her off of the ledge. Fortunately she had had the sense to reveal herself in time for him to grasp her. Once they were both standing safely, she spoke up.
"What is going on Loki?"
"Frost Giants…"
The look in Sigyn's eyes told him that he didn't need to explain any further.
"Where have Thor and Odin gone?" she quickly asked.
"To the vault…"
"The Casket! We must hurry to them!" Sigyn declared transporting Loki and herself off of the ledge.
She was unable to transport them directly into the vault thanks to protective magic that she herself had cast over the important room. Instead, she teleported them right outside the vault's doors. She was about to make her way in when Loki grabbed her arm.
"Let Thor, Odin, and I handle this Sigyn. You should find Sylvath and let him know that you are safe." Loki urged.
Sigyn wanted to join her brothers and the AllFather, but she knew that Loki had a point. Sylvath would be worried sick if he could not find her. Sigyn nodded in agreement with Loki's request.
"Very well, but the moment you and Thor have finished you both must meet me in the library to tell me what has happened."
Loki agreed to her request and entered the vault as Sigyn left to find Sylvath. After leaving Loki, Sigyn took a moment to quiet her mind before trying to reach out to Sylvath. Normally this would be an easy task, but there was still a multitude of people running about the palace in a frenzy. She was finally able to drown out the ruckus and reach out to Sylvath telepathically.
"Father?" The voice inside her mind asked.
"Sigyn?" He replied.
"Where are you?" she quickly asked.
"With your mother in the throne room."
"Is all well?"
"Yes, my dear."
"I will be there momentarily."
Sigyn broke the connection, relieved that her aging father was safe. She teleported herself to the throne room where she found Frigga and Sylvath waiting for her. She quickly embraced her mother whom she had not seen in almost eight years, and then quickly embraced Sylvath. The ancient Light Elf was the closest thing to a biological father that Sigyn had, and she was comforted to know that he had not been harmed by the Frost Giants.
"What damage has been done?" Sigyn asked Sylvath hoping that his magical powers were strong enough to see past her protective enchantments that surrounded the vault.
Sylvath closed his eyes for a moment and the white markings on his hands and face began to turn golden. "The only casualties are the guards that were in the vault, and the Frost Giants who invaded it… I cannot be certain, but I do not believe anything was taken." He replied before opening his eyes once more, and the golden markings returned to their white state.
Sigyn took a deep breath and relaxed slightly. She knew Loki and Thor would be able to confirm or deny her father's statement when she met them in the library.
"Tell me Sigyn, is not the protection of the vault and its artifacts your charge?" Sylvath queried.
Sigyn nodded her head.
"How is it that they were able to enter it?" he pressed.
"I am not sure…" Sigyn responded truthfully, hanging her head ever so slightly.
Frigga took her daughter's chin in her hand and raised her head so that their eyes met. "This is not your fault Sigyn. Do not torture yourself with guilt."
Sigyn gave Frigga an appreciate smile before growing serious once more.
"The magic of the vault is more concerned with protecting the individual items held within. The Casket is guarded by the destroyer, and other important items are guarded by spells that only I can bypass. It is impossible to teleport into the vault, which means that the Frost Giants just walked in through the front door."
"Why would you keep people from teleporting in, which is a rare ability to begin with, yet leave the front doors unprotected?" Sylvath questioned.
"That is what worries me, the doors are not unprotected. There is a seal that reserves entrance to the vault for specific people. The AllFather, Thor, Loki, Frigga, myself, the guards of the vault, and several other high ranking Asgardian officials are the only ones who have access to the vault." Sigyn explained.
"And that is why you are concerned." Sylvath replied now understanding his daughter's worry. "Either an extremely powerful sorcerer managed to break the seal, allowing the Frost Giants to enter, or…" he broke off.
"Or what?" Frigga asked in a worried tone. Neither her daughter nor Sylvath answered her. Instead, they regarded each other with a look of mutual understanding.
"Father you are the most powerful sorcerer in the Nine Realms and not even you could have lifted the seal…" Sigyn pointed out.
"You realize what you are implying then, do you not?" Sylvath asked.
"I do." She replied firmly.
Frigga, normally calm in these situations, finally lost patience. "What is going on!? What are you saying?"
"There is a traitor in Asgard." Sigyn replied in a tone that left not room for argument.
