The Ancient Era has come to an end. Gods, demons and ancient beasts strong enough to rule anything with power and roam free in the universe... All vanished mysteriously.

No one really knows how it has ended and what actually have happened. Some records state that it was the constant war between gods and demons that caused their demise, or even the conflicts they had against members of their own race that ended that golden age.
