The Heroes Lose (Twice)

In the year 4000 AGD (After Goddess's Death), the world of Ardun suffered the greatest tragedy since then: the arrival of the one known as the Demon Lord.

With the arrival of the Demon Lord, the race of creatures known as Demons poured out of the rift in the sky from which the Demon Lord first emerged. They sent forth hordes of monsters into human settlements and seem intent on conquering all of humanity.

Despite stiff resistance, the Demons are winning their war with a ferocity not seen in any other opponent. In desperation, the temple invokes a forbidden ritual that calls upon the Goddess's very essence to summon warriors from other worlds to fight.

With their success, the 3 warriors (Yoo Jeongyeon, Park Jihyo, and Son Chaeyoung) are summoned and must save the world with their immense power.

At the same time, the Great Seer, within his prison within the Demon Lord's Keep, is troubled with strange visions. He sees the destruction of the world and the ultimate failure of the warriors but does not see Demons as the cause and that there may be more going on than anyone knows.
