Hello there :)
After I read almost every Loki fanfiction I was shocked to find none where Loki could use Mjölnir.
I mean... come on... the scene in the movie Thor where he tried to lift up the hammer screamed almost after such a fanfiction.
Perhaps I will make this story later Loki/Sif or Loki/Oc, but I don't know yet... I don't even know how many chapters it will have. I think it depend on my motivation and time to write...
Oh and I should warn you: I am not a native english speaker, so it can happen that there are some mistakes...
However... enjoy the story ^_^
Thor was banished to Midgard. His mistake was it to attack Jotunheim against the will of the allfather. He overestimate his power and his hubris begot Asgard almost war with the Jotuns. If it was not the allfathers intervention he would have died, along with the warriors three and Loki.
But it was not just the banishment that was released with the battle on Jotunheim from the five gods. No, something else happend there.
By a frost giants touch Lokis hand turned blue and he realized that he wasn't an Aesir. After he arrived back on Asgard he went strikt to the relict hall and picked up the cube, that Odin brought a long time ago from Jotunheim and watched with shock how his skin turned blue again and how the Jotun typical lines appeared on his flesh.
He realized that his brother Thor was not his real brother, his so called father Odin not his real father and Frigga, his mother not his real mother. He was a Jotun - the monster that the parents told their children at night.
His whole life was a lie and now, that he knew, everything made sense to him - why he was always so different, why he always stand out.
It was a unfortunate event, that Odin, the allfather fell into the Odin sleep when Loki confronted him with the lie that he called his life. Wasn't it appropriate that the God of lies live until then in a big one?
He discovered that he was the son of Laufey, the king of Jotunheim and that Odin took him , because he thought it would be a great chance to unite the kingdoms in peace. The confused, from self disgust corroded men became the king of Asgard and should be it until Odin awakes or Thor comes back.
But Loki had an other plan in his mind. He wanted to show the Aesirs and his father that he was after all worthy and that he was better than their precious Thor. Magic was despited in Asgard and so he, who used it, often too. But now he would show them what a great sorcerer could do.
Yes, he would find a spell that would allow him to use the power of Mjölnir. He would show the Aesirs what real power is.
