The world is like a system, divided into mechanisms. In ancient times, there were gods, demons, humans... As time went by, some things were like shell crabs left on the shore when the sea rose. These gods knew that besides them, there were things older and more powerful than them. In other words, they were also created by this thing. They call this thing "forbidden."
?
I don't know when God suddenly knew some secrets about "restrictions" and the theory of time and space. There are other worlds outside the world we know, which humans today call "parallel time and space." This made many gods and humans panic and even led to riots, resulting in numerous deaths and injuries. In order to maintain order in all walks of life and quell riots, the gods at that time erased all memories of those who had nothing to do with it, and negotiated an alliance to jointly protect the safety of all time and space.
?
So far, the alliance has been divided into departments with different responsibilities.
Various races fight openly and secretly, not wanting their own clans to disappear, but also to maintain the balance of time and space. They have been living in peace and harmony for a long time, but something happened that made them think they could know more secrets of the 'forbidden', but a hand was slowly surrounding them, trying to recreate the scene from ancient times...
Concept: There is no real right or wrong in this world, it's just differences in experiences and positions.
