When coming of age a person is determined by the ability they conjured from the deepest depths of their heart, their ability to determine their future, so having a trash ability make one a laughing stock of the era, while those who got high-level becomes the top of the world.
And you who have reached the right age have participated to awaken your ability along with a batch of kids with the same age as you.
As you drank the serum to awaken, you closed your eyes like everyone else, you entered a dream and witnessed a huge human covered by darkness veil that covered the entire world, you look around and spotted everyone who drank the serum standing.
From scrutiny everyone was standing on an island and the huge giant figure covered by a large veil is holding the island with its left hand.
You heard it muttering as it thrown several seeds entering their bodies.
At that moment you realized that what anyone awaken is not determined by fate, it's what this being allow to grow.
And you were discovered by it, you locked eyes, but that figure wanted to drag you and destroy your soul, but you were faster and closed your eyes returning to reality.
Alas because you have driven the entity to its awareness, you were not given an ability.
