Great War

The Great War (大戦) is a worldwide conflict that occurred during the Mythical Age, between the demon kingdom of Dilhade against the alliance of the human continent of Azesion, the spirit forest of Aharthern, and the divine realm of Azure Sky of the Gods. It ultimately came to an end with the Demon King Anos Voldigoad's sacrifice, who erected magical barriers to isolate the four races for a millennium so that their hatred would disappear in due time.

Two thousand years later, an attempt to restart the Great War was made by a radical group of humans led by the fallen Hero Jerga with the aid of the Heavenly Father God Nosgalia.

Summary
The war went on for so long that the reason why they were even fighting was lost. No one knows if it was humans or demons who made the first move. But once it happened, it began a cycle of murder, revenge, retaliation, and death. Humanity, who was naturally weaker than the demon race, received support from the spirits and gods. Likewise, the demons who constantly fought one another banded together against their common foe.

History
During the highpoint of the Mythical Age, various demons fought amongst each other in order to become the ruler of their races. Many of them invaded Azesion in order to expand their own domains. The fire of war embraced them both inside and outside the country, and each demon was forced to with their internal enemies as well as independently deal with the more organized and united humankind, and the spirits and the gods who assisted them.

Humans and spirits feared that the demons would become united, because it was the demons' internal conflicts that made it possible to maintain the balance of power between Azesion and Dilheid with equilibrium. If the demons had a single ruler that would be able to unite the entire race under one banner, the course of conflict would instantly overturned.

Azesion's army continued to cunningly sow the seeds of distrust in the rulers who dominate the various regions of Dilheid. By forcing the demons to fight each other, they planned to increase the advantage in the Great War and while the demons underestimated the humans by considering them to be insignificant race. The humans were able to influence the course of hostilities and their goal slowly but surely bore fruit.

Over the course of the Mythical Age saw the rise of many powerful "king-class" demons, who possessed enough power to rule over a domain of Dilhade, as they raised armies to battle their enemies to seize full control of Dilhade and crush the enemies of the demons. The most prominent and powerful of these were the Four Evil Kings: the Conflagration King Eldmed Ditigeon, the Netherworld King Aeges Code, the Cursed King Kaihilam Jiste and the Scarlet Stele King Grysilis Derro.

However, one more contender emerged from the shadows. This figure was the Demon King of Tyranny Anos Voldigoad, who soon became known as the most powerful demon in Dilhade. He and his army succeeded in bringing down the Sun of Destruction, as Anos turned the Goddess of Destruction Abernyu into his Demon Castle Delsgade, which he built in the city of Midhaze. Afterwards, he and his army repelled the armies of other demons who attempted to conquer the city of Midhaze in the aftermath of Sorcerer King Bomiras Heros' death, as Anos brought city under his control.

Meanwhile, in order to respond to the rise of the Demon King Anos, the humans formed the Demon King Subjugation Battalion, a elite army created to battle and defeat the Demon King. While choosing the who would become the leader of the army, many advocated for the selection Hero Kasim, on the account of his superior swordsmanship and command over holy magic. However, Kasim proved incapable of lifting and wielding the legendary holy sword: Evansmana, the Sword of Three Races, to which the Demon King was vulnerable against. Ultimately, Kasim's junior, the Hero Kanon proved capable of wielding Evansmana and became the leader of the Battalion, as he lead them in countless battles against Demon King Anos and his army.

During one battle, Anos was able to corner Kanon, but the latter managed to force him to retreat despite being put in an unfavorable position. Over the course of the war, Anos and Kanon gained an unspoken respect for each other, as Anos became fascinated by Kanon' courage and strength of will.
