Long ago, when the world was recovering from the chaos left after the Great Calamity War, five mortals succeeded in achieving godhood.
These five individuals, Silvermoon, Everbright, Dreamweaver, Lancaster, and Nightfall, ascended from the Mortal Domain through the Spirit Domain and into the Upper World, the highest of the five layers of reality.
In this realm, they became the pinnacle of knowledge and power.
As the Calamity-ranked beings, their influence is so vast that their mere gaze can cause the lower realms to tremble, and a direct clash between them would redraw the geographical map of the world or cause a global catastrophe.
To avoid such a reality-shattering conflict, the Five Calamities swore the Oath of Balance between them.
The Oath stated:
None of the Five Calamities shall engage in direct warfare or cause physical harm to one another, nor shall they strike any individual belonging to their respective bloodlines.
It became their rule.
