Everything was peaceful and development of a magic society began and ended two thousand years ago. When a deranged necromancer used their power to raise the warriors gathered by Henry's daughter back from the dead as undead servants. That deranged necromancer was successful in turning them all into undead they than had them train other undead monsters and make them as destructive as the original elite warriors. However this deranged necromancer later used necromancy to raise an entire army of undead and had the warriors train them and over time those first undead became generals leading the undead while the leaders led them all soon they killed the deranged necromancer and continued to raise their numbers and better their individuals. Unfortunately one thousand years ago those undead attacked for the first time over taking over half of the world and forcing the other half of the world to be the only safe place everyone worked together to create an impenetrable and unbeatable defense. After taking over half of the world the numbers of the undead multiplied by thousands of new undead as a result they had to begin training these new undead to become invincible warriors. Five hundred years ago those undead warriors attacked once more after a corrupt noble allowed them in. Unfortunately this allowed the undead to take over almost half of the remaining world and turning it into their territory. Where the new undead were trained to become monster like warrior's. Two hundred Fifty years ago the undead attacked again taking over almost all of the world all that remained was a single human nation. After the rest of the world was overrun with undead the new undead had to be trained and turned into monster's.
