The very first war of the world occurs in the origin story. It can be traced back to its version of the Fallen Angel, a deity who once was good but he had a different desire than his brethren. This longing was either a lust for power or control over the world. Seduced by his yearning, this deity fell from grace, and gave into the darkness lurking in his heart.
The Fallen Angel is the progenitor of all evil in the world. He creates new species, typically corrupted versions of those loyal to the gods and goddesses, to serve him and aid him in his plans for conquest. He raises great armies and before long, he unleashes them against those he once called family.
Thus the first war between good and evil begins. Since it features beings with godlike powers fighting each other, the war proves to be far more destructive than subsequent ones between mortals. These battles tend to be apocalyptical as mountaintops are ripped off, pieces of land are broken off the landmass, and so on.
The Faithful, those who fought on the side of good, worked to keep the world they loved from being ravaged by the forces of evil. Though it pained them to see the people they had created die fighting evil, they knew they had no other choice but to keep fighting until the war was won.
Tossing his wicked servants to fight those who wished to protect the world wasn’t the only weapon the Fallen Angel had at his disposal. He employed greed, jealousy, and the other flaws of human nature and used them to sow discord across the land. He pitted friend against friend, brother against brother, and husband against wife to weaken his enemies.
After a long, protracted war, both sides gear up for the Great Battle, the one that would determine the fate of the world. The Great Battle becomes the most destructive of all the battles of the war as both sides go all in, wanting to be the victor. Eventually the Fallen Angel’s forces lose ground and before long, he is defeated and imprisoned.
Victory comes to the forces of good, though at a great cost. The primordial world was destroyed due to the cataclysmic battles. As a result of the Fallen Angel’s desire to rule, the world that was once pure became contaminated due to evil touching it. This pureness was forever lost, never to return.
But the discord the Fallen Angel created with his policies would persist and cause the world much turmoil in subsequent eras. People were no longer content in their lives as greed and envy and other dark elements of human nature remained with them. And some would follow the Fallen Angel down the road to evil.
