The law of the universe
/*unedited*/
Since the beginning of the universe, there is an entity that controls everything and put them in order. We call it, the law.
The law puts everything in line and it is absolute.
However, since the creation of the universe, there is something that either merges with the law or diverts from it. It is called free will.
It is either planned by a higher being or was created by mistake but freewill became the crucible to chaos. And because of that there formed two factions within the universe. Those who follow the law and merge with it or go above it became rulers and deities, but those who divert from it and bends it became the rebels or the outcasts.
Thousands and millions of years have passed and those who are called outcasts are now starting to make their move. They began by entering the planets and slowly corrupting the mortals within and adding them to their ranks.
