Loki silently slipped into the cold room, and gazed into the darkness. He muttered a spell under his breath, and made a small orb that emanated a powerful green light appear in the palm of his hand. He walked over to the nearest shelf and gazed at the thousands of volumes of books that were seated on it. He glanced over each quickly, until he had located what he needed. He grabbed the book from the shelf and extinguished the light.
Like a shadow, Loki disappeared from the room and began weaving his way through the many halls of the castle that he had grown up in alongside his "brother" Thor, and until recently, had been a prisoner in. Loki smiled to himself as he recollected how relatively easy it had been to escape, and how easy it would be to finally take his revenge on the people he hated the most. While he was a prisoner it had been all too easy to earn everyone's trust, just as it had been too easy to earn back Thor's trust.
After the battle on Earth, and Loki had been captured and taken hostage as a prisoner in the realm he had once ruled over as the rightful king. Bound and filled with a burning hatred he was brought before the all-father to have judgment passed over him for his crimes. But, much to Loki's surprise, Thor had defended him saying that he had completely forgiven his "brother" and that to punish him would be a terrible mistake. Had Loki not loathed Thor with such a strong passion, he might have even felt grateful towards the other god.
What shocked Loki further still was that Odin had been swayed by Thor's defense. Loki was not to be stripped of his powers and exiled as first planned, but to be imprisoned until it could be proven that he was trustworthy enough to be released and restored to the throne as a prince of Asgard and a son of Odin.
It took all of Loki's self-restraint not to laugh in their faces at their blind stupidity. Instead he played the part well of a broken prodigal son desperately seeking forgiveness. He had even knelt before the man who had dared lied to him his whole life and called him "father" and called Frigga "mother" and beg of their forgiveness. He held back a satisfying smirk when he saw a single tear fall down the Queen's cheek. He finally allowed Thor to embrace him warmly, even though he wanted to spit in his face and tare the flesh from his body.
Loki was led away by two armored guards to the cell that would confine him, until he could escape and extract his glorious revenge. He was chained by the wrists and ankles to the back wall of the cell, and the bars were reinforced with a special magic put in place by Odin himself that greatly weakened his powers. This did not concern Loki, for it did not weaken his silver tongue.
The two guards took shifts guarding over Loki; the male during the day, and the female at night. They would give daily reports to Odin on Loki's behavior and made sure that Loki was feed properly. At first the guards were very rigid and always on high alert around the imprisoned god, but as time ticked by and Loki proved to be an absolute perfect model of goodness they began to relax... this was their first grave mistake. The second happened two months into his imprisonment when the female struck up a conversation with him.
Her name was Selieve. The moment Loki learned the female guard's name; he knew she would be the key to his freedom. He began putting his silver tongue to good use, and over the next four months Loki formed with Selieve what she believed to be a friendship. Of course, Loki also noticed the rosy blush that would come to her cheeks and the brightness in her eyes whenever she was in his presence. Brokol (the name of the second guard Loki learned much later) would converse with Loki as well, but more from shear boredom than from the desire to, like Selieve.
It was Selieve's daily reports to Odin of Loki's impeccable behavior and changed ways that led Odin to decide that it would be safe enough to travel to another realm briefly without the worry of Loki attempting escape. As soon as Loki heard this news from Selieve he had told her that he was grateful that Odin was beginning to trust him again, but on the inside he celebrated that this was the opportune moment he had been waiting for.
The night Odin left and Selieve began her shift Loki's silver tongue gleamed brighter than ever. He weaved lavish compliments of her beauty and grace. He watched with increasing pleasure as her lust became more and more prominent.
Around mid-night, Loki asked if he could have his dinner. Because he was still seen as the son of Odin, Loki's meals were more lavish than the average prisoner, but were usually served to him on plain levitating plates to prevent the guards from getting too close. However, in the last month Selieve had been comfortable in his presence to go into his cell and serve him herself, and even eat alongside him occasionally. Loki always remained chained to the wall, but he never once did anything that made her fearful.
His bright green eyes never left her as she slowly opened the cell door and walked over to Loki, plate in hand. She handed it over to him, but he slowly set it down on the floor beside him, never breaking eye contact. She looked at him with question in her eyes, but Loki stood straight up once more and placed a hand gently upon her cheek.
"Loki..." She questioned, but he cut her off by placing a finger upon her lips.
"Shhh... Be calm my beautiful Selieve." And with that he placed his lips firmly upon her own.
He instantly felt her melt into his kiss as her breathing became rapid. She began weaving her fingers through his long black hair, and he placed his hand firmly on her hips. The kiss became more heated and Selieve groaned with pleasure as Loki felt a smile form on her lips.
"Do you know how long I have wished for this?" She whispered into his ear.
"As long as I have, my love." He whispered back. He kissed her more firmly, while he traced her neck with his left hand.
"Selieve?" He asked after a few moments, breaking the kiss.
"Yes, Loki?" She inquired, her voice sounding as if she were dizzy from too much wine.
Loki slyly smiled, his bright green eyes flashing,
"Thank you."
Selieve opened her mouth to inquire further, but before she could utter a word, Loki grasped her by the throat tightly and threw her back against the wall. Her head snapped back and hit the wall with a loud echoing thud. She stumbled back up and reached for the dagger on her belt, but in a flash Loki had grabbed hold of one of his chains and wrapped it tightly around her neck. Selieve struggled and put up a good fight, but the god proved to be too strong for her.
Loki watched as agony and betrayal filled her eyes, and smiled like a mad man as all life slowly drained from her face. As soon as she lay still, Loki set her down gently and retrieved the keys from her belt. He unlocked the chains that bound him and sighed with relief. He looked down at the still figure at his feet.
"Forgive me my dear, but it had to be this way," He apologized knelling down and brushing her dark hair from her pale face. "It is truly a pity to destroy such a beautiful creature, but I must have my revenge." He closed her eyes, and gave her cheek one final stoke before standing. He walked through the door way of the cell and felt his full powers return to him. Loki smiled and laughed out loud. The first step in his plan was now complete.
He quickly made his way up the stairs and out of the dungeon. He had one final stop to make in order to complete his ultimate plan. While he sat in his prison cell, he had remembered a certain incantation that he stumbled upon when he was much younger and more naive. In order to do defeat The Avengers he needed to surpass them in power, and this spell would be just the thing to increase his power.
Sometime later, Loki stood at the edge of the bridge and gazed down into the eternal darkness below. With book in hand, he gazed back over his shoulder at the towering kingdom of Asgard for one final time. He felt tears well up in his eyes, but quickly reminded himself that he didn't belong there- that he didn't belong anywhere. Loki took a deep breath and leaped over the side of the bridge. The familiar and agonizing feeling of the darkness encased him as he plummeted towards his destiny.
