In real norse mythology, Loki gets his mouth sewn shut. Now, what would happen if this happened in the Marvel Cinematic Universe? I don't own any of the characters. Just saying. :3

Long ago, two races ruled over Earth: Humans and Monsters. One day, war broke out between the two races. After a long battle, the Humans were victorious. They sealed the monsters underground with a magic spell. Many years later... they say who climbs Mt. Ebott, n e v e r r e t u r n s. Untill a child returned. *The barrier has been broken Have you ever wondered why humans are so violent? There's a simple answer for a simple question, they're scared. And what do people do when they're scared? They attack. Some people have welcomed the monsters to the surface, others have not. The others are scared. But who isn't? When you find out a new species besides humans walk on earth and are capable of everything a human is capable of and more how can you not be scared? But of course there are people on the fence that say they just don't care. Humans and monsters have came to an agreement. As long as monsters don't attack the humans won't attack. So, that there will be peace on Earth. But in reality nothing really is in peace. They just say that to comfort the citizens But I know, I can see through their lies, but I don't care. I'm more of a person that's on the fence, who knew a fence could be so comfy?

It all began when someone left the Window open.

Sans goes through another almost Genocide Route, but the most unexpected thing happens. The human loses their soul and is used to break the barrier. Sadly, the remaining monsters weren't greeted with a warm Welcome.
