Will of Heaven.
Long ago, modern humans thought they discovered the nature of reality and branded things such as heaven, hell, and soul as fabrications by their ancestors made when they had to cope with a powerful nature.
They were sure that they were right or at least, their ancestors were wrong.
Ironically, they were proven wrong four hundred years later.
In 400 YAB, an alien species appeared out of nowhere and nearly drove humanity to extinction.
At that time, the Abyssal Kings and Queens didn't appear in front of humans yet. There were many speculations and theories why this was the case.
But even without them, Abyssals had significantly more awakeners in each level and easily overwhelmed humans.
Humanity was driven out of planetoids and moons. Back then, these areas weren't fortified as there was no external threat. It happened so fast that no one really knew what was going on.
