The power that determines the fate and destiny of all creatures in the world is the will of the heavens that is in charge of maintaining the grand net made of countless threads of fate and strings of destiny.
Every creature and every entity and even inanimate objects like rock and sand have a destiny of their own.
Stars die off and burst into supernovae, creating a foundation for the birth of new stars; such is the destiny of a star.
Even black holes are susceptible to 'change,' let alone ordinary beings like humans.
Strings of destiny and fate connect the entire world and maintain 'order.'
If there were no threads of fate and destiny trying to actively maintain the 'balance' and 'order' of the world, the world would collapse all by itself, as catastrophic world-destroying events would have a higher chance of happening.
The Sea of Endless Miasma is one such catastrophic existence; it is the literal embodiment of destruction and decay.
