The forest was more chaotic than ever. Monsters who lived within the forest for decades were frantically avoiding the creatures that suddenly emerged, and those creatures were doing the same.
The animals of modern Earth, warped by mutation and forced evolution, felt something instinctual stir within them. A deep, unsettling insecurity triggered by the world's unnatural cleanliness. The purity of this world's mana clashed violently with the corrupted essence they had been born into. Their cores reacted instinctively, painfully, to the imbalance.
So they fled.
Fled from the safety of the unknown monsters, fled from the pressure emanating from Noah's and the drake's battle, and the strong fled to find a place to adapt.
Driven by instinct, these creatures knew survival meant change. And change meant power. So long as they lived, they could evolve. They could grow stronger.
And some creatures of Earth understood that better than the others.
