In the beginning, this world was a normal world, somewhat like the Federation, where people of various Races lived in relative peace and prosperity.
However, everything changed after some Kingdoms began to flourish.
A dark wave appeared in the sky, clearly warning everyone that horrible things would happen if they didn't obey it.
At that time, the civilization on the continent named Celestial Ridge was at its peak, so naturally, people paid no heed to such things.
Especially the dominant Rexin Kingdom on the continent at that time, whose King led by completely ignoring this order; not even waiting for nightfall, a terrifying wave began to circulate.
In a matter of a day, half of the citizens of this massive nation of millions were dead.
This act terrified numerous countries, and at that time, nearly every existing entity knelt down and submitted to that wave.
Because this Power was so immense, they couldn't see any opportunity for rebellion.
