Now would be a good time for the first big twist
This early, fam?
Other boys do exist.
owever, there's an invisible barrier (even to the Extra-Normal) that exists between all of the Extra-Normal which protects them from being directly affected by each other's abilities. This is known as an Emotional-Field. It also lessens the blows behind each of their abilities - which means an Awakened with super strength can't one-shot everyone, a pyromancer cannot fry another one, a mind-controller cannot effectively mind controlling another. However, this depends on the ability and while a majority of abstractions are affected by the Emotional-Field certain abilities bypass it completely. It's case by case.
Farmer Hill, Montana.
A place few people have heard of, being a small town in the middle of nowhere. However, it couldn't have been more important. Eons ago, all the magic in the universe was used to seal a powerful God-like being known as the Glutton. This thing was an incomprehensible ball of orange light that tortured countless universes and then devoured them and has feasted to the point where it was near invincible. Its rampage was brought to an end in the universe of Glint where combined forces brought the thing down and sealed it in a mountain in a different universe. That different universe is the world where the story takes place, and that mountain was Mount Ever Reaching in Farmer Hill.
It was where the Glutton lied dormant for ages upon ages - the League of Luminscience manipulated Farmer Hill to keep the citizens away from the mountain and the existence of magic a secret. However, it all changed when the seals that kept the Glutton dormant were broken by somebody's foolishness and it was allowed to feast off of what sustained it: emotions. The Glutton's first action was attacking a campsite full of people by corrupting one powerful minion and inadvertently Awakened the people that would defeat it. It tormented this group as they tried to find a way to defeat it; ultimately knocking them into a coma for a few months.
In this few months, the Glutton turned Farmer Hill upside-down - mind-controlling countless people and turning the town into a chaotic warzone. Anyone who entered Farmer Hill was enthralled as well and in this chaos; the Glutton slaughtered any Awakened or Extra-Normal beings that it could with impunity and tortured them endlessly in its domain. However, the Awakened that was put into a coma, well, awakened from it and rebelled against it. Ultimately, they engaged in one final battle against the Glutton in the mountain and, out of desperation to escape, the Glutton broke the seals that were binding it. However, by doing this the Glutton injured itself to the point where it was eliminated and the multiverse was free from it.
However, these events were reversed as a new timeline was born from the "death" of the Glutton. A new timeline where Farmer Hill was destroyed in a catastrophic earthquake and the Awakened that the Glutton killed were resurrected. However, with the death of the Glutton, the magic was returned.
