Forsyx remembered there were a lot of theories regarding the start of the Apex game world in his past life.
The most famous one among them was about these wild zones.
Basically, according to that theory, most of the inlanders in the game world had, at some point, come here through these wild zones.
It's just that the species living in the game world were so weak that they were unable to stop the wild zone's growth.
At some point, those wild zones expanded so much that entire invading species came to the game world permanently, destroying the space cracks.
This was a widely accepted theory because of how different species use the same mana in different ways.
According to this whole theory, the game land went through a series of wild zone invasions.
The first to invade were mid-sized creatures; they became the inlanders and thrived in the game world, but then some big-sized creatures invaded the land.
They hunted the inlanders of that time and replaced them.
