The monsters could not be bargained with, nor did they seek out something tangible like world conquest. Two hundred years ago a legion of creatures known as the Evil Deities suddenly appeared and began to lay waste to the New World. They are the reason why the New World has a decimated population, responsible for killing most of the dragons, and convinced Platinum Dragon Lord that creatures from YGGDRASIL are evil. Walking Spoiler: They were the second group of YGGDRASIL MMO player characters to enter the New World.It appears he recognizes the structure or the original guild from the YGGDRASIL MMO. Forbidden Zone: The Floating Palace of Eryuentiu is designated as such by Momonga after learning of its existence in the New World.Platinum Dragon Lord resides within the fortress and keeps vigil over the Greed King's fearsome guild weapons. It was the guild dungeon of the Eight Greed Kings and might have similarities with the Great Tomb of Nazarick. Eternal Engine: The Floating Palace of Eryuentiu continues to manufacture equipment and magic items despite the deaths of the Greed Kings.This eventually brought about death, either from each other or the New World resistance. Brought Down to Normal: Each time the Greed Kings died they suffered resurrection Level Drain, growing weaker and weaker.This internal conflict greatly weakened them, making it possible for the oppressed races to rally and destroy the Greed Kings. However, unwilling to share the prize, the Greed Kings began to squabble and war among themselves. Unable to oppose their immense armies and invincible magics, the New World was easily conquered by them. Their arrival heralded an age of unbridled death and destruction, ushering terror and misery to all. Terrible beings who appeared in the New World five hundred years ago.
Which means that by the time the Greed Kings appeared, only one of the Gods was left (possibly due to him also being an undead creature), and he was no match for a full eight YGGDRASIL players and killed. Worf Had the Flu: Turns out the Eight Greed Kings' rampage not really involving them much one way or another was for a very good reason: it turns out that YGGDRASIL characters -or Player Characters at least- that enter the New World get the same lifespan beings of their race/species would have there.They are the reason why the New World has a magic system (and terminology) that mimics the YGGDRASIL MMO, which initiated the fall of the dragons by inadvertently corrupting the native Wild Magic system.
