The boy sat at the base of the World Tree, gazing upon it's branches and listening to the whispers of it.
The boy sat, in his true skin, cerulean skin and ruby eyes, learning the truth.
Ragnarök, or a heartbeat as it is called by few, its cycles and ends were spoken and understood.
The truth, that Odin is not the most powerful being in the nine realms, that there are two beings, The Master of Time and The Master of Knowledge that wish to have a third member.
The group of elementals that wish to take ultimate power and their henchman were spoken of as well.
The reason behind his adaption, the reason for Thor being favored over him and the reason why he was here was spoken too.
In fact he was told everything.
….
This is how the Chitauri found the boy, gazing upon the World Tree, something that no living thing should be able to do. They took the boy, who not struggled at all, to their Master.
The Master 'taught' the boy to hate his life, but he would not listen.
So the Master took the scepter that was taken from Asgard's treasury and 'convinced' the boy, told him about freedom being life's greatest lie, told him about how he was wrongly thought of being weak and that in return for Thor's precious Midgard he was to give the Tesarach to the Master.
So Loki went to Midgard to get the Tesarach to his Master, even though deep, deep down he felt what he was doing was wrong.
….
So now 2 years since the attack on Midgard and 3 months since Loki had started his job as prankster of the Avengers' tower, Loki was now playing co-op Portal 2 with the Master of Knowledge in a building nearby to said tower while the Avengers were with Mrs. Fury.
Loki had burst out laughing when Danny told him that when he arrived at his former Avenger tower floor.
So the two powerful beings played on and discussed future plans, while the Avengers' were facing near death.
(Sorry if this is random, but it is not. It gives an explanation for SAPMI and what Loki did while in the void.)
