For a long time he let thor and his friends laught at him. Never did he stop smiling or smirking for their stupidity.
Being a sorcerer was seen as a womanly way in asgard but he didn't care, why would he? He had more power at his finger type than anyone on his home save a few select like his father or his brother.
From a young age he understood his difference, he was no aesir. Too lean, too small to be an asgardian. It took him time to understand what he was but one couldn't dwell in the art of sorcery without a sharp mind.
His first reaction was to lash out, he yelled and cried, his whole life based on lie. He tried to reason, to think on why his family lied to him but he couldn't reach an answer. It explained so much, why he was different and why he could never please his father.
As he thought of his life, his only constant was the love of his mother who helped him learn the art he so much love, who loved him no matter what his people said of him. He couldn't push her out of his life even if there was no blood bond between them.
Thor coronation approached and he found he didn't care anymore, what good ruling would bring him. Sure he could make sure his brother wouldn't be made king, he could bring some frost giant in asgard to make him look like the spoiled kid he is but what would it bring him? A hurtful lie, one that would hurt his mother. He did not care if his lie hurt but not his mother, never her.
As such, he just stopped trying to belong with his brother or his people. He stopped searching the attention of his father. He just kept on working on his spell, his art.
As strong as he was, magic is an ever evolving art where nothing was set, everything changed. With the help of his mother, he invented spell never imagined before, he summoned beast from legend and created being of magic.
Sadly, his introvert way was seen as insanity and his father forced him to "help" his brother on his adventure until he was made king. The warriors three were not pleased by his presence but seeing that he was not trying to speak or interact with them, they let him be.
Every time they spoke of his spell, of his art, they just mentioned them as trickery not worth mentioning even if said trickery saved their lives.
Their comment kept on but he ignored them. They were warriors, they would never understand what sorcery could really do and he would never show them.
As soon as he could, he would leave this realm, leaving behind his title of prince and this barbarian. Midgard would be a good start. Last time he went there, they mastered thunder and made carriage that didn't use horse. Their short lifespan made them advance faster and it would be nice to see where they would go, would they destroy themselves or reach the other realm?
He did not know but they were interesting and for him; it was all that matered.
