For over a thousand years, the Continent has been divided into two sides: the Monster Realm, home of the all-powerful Dark Lords and the monster hoards that they command, and the Human Realm, home of humankind and its kin.
In the year LP0007, the forces of the monster army suddenly invade the Human Realm, striking with both overwhelming strength and ferocity.
The civil war between Dark Lords, which had been locked in a stalemate for several years, had finally ended. Its victor, the Dark Lord Kayblis, was declared ruler of all of monsterkind.
His first decree was to take back the human territories using all of the forces at his disposal.
While the major human nations of the world attempt to fight off the invading threat, the immense power difference between their armies and the united monster army quickly becomes clear.
Humanity's strength steadily begins to waver in the face of the seemingly unstoppable foe.
The Human Realm's major world leaders hold a summit to discuss a means of combating the monsters, but are unable to reach an agreement between each other.
