Lord Shadow

Most Hunters in the world joined the Mercenary Association.  It is the largest independent organization that is acknowledged by the Seven Great Powers.

It had its own currency and services it provides to people who hunts. 

The Mercenary Association is affiliated with many other world powers as they supplied most of rare treasures and materials in the worlds.

Most of the hunters that register with the Mercenary Association would get all kinds of benefits like insurances against their death and he guarantee that their family would be provided for after their death.

It is also because of such benefits that the Mercenary Association usually give one year and a half trial period to any hunter before they are qualified to register their name into the Mercenary Association.

The Mercenary Association is given the list of the forbidden areas by the Seven Great Powers and in turn, the Hunters tell the people of the forbidden areas.

But of course, this kind of measure alone is not enough to stop people from accidentally entering these forbidden areas.

And because of that there is other measure. The location of these powerful monsters is guarded by the military of the world powers

This is one of the reason that Death Monarch separated the seven continent and giving it to any faction powerful enough to hold it. 

Not only that they are now hold legitimate power over the continent they rule, but they also have to bear the responsibility of the safety of that continent. 

Death Monarch had written this trap in the Article of Distribution.

And it is not like the one accepting the Article could not see such trap. They know of it and they jump in willingly. 

Only a powerful enough faction or organization could hold a continent and protect its people. When Death Monarch wrote the Article, there is a pragmatic approach to it

He knew that not all of the great powers that he acknowledged is clean. 

But, they have enough power to protect the people living in their dominion. Whether they like it or not, they have to protect the people living there.

Because if they could not prove to the world that they could hold a continent and pacify it, then they would be deemed unable to take the burden of the crown and they would be replaced or usurped by another force

They took and sign the article because the temptation of power is too strong for them to resist. 

Each great power is responsible for the forbidden areas of their continent. 

Death Monarch knew that if he controls the world and suppresses all of these forces, the responsibility of protecting the world also falls to him. 

And Death Monarch was never a man that wanted the world to be under him

He did not have the desire to fight or contend for the hegemony of the world. That is not in line with his character. 

It is ironic then that the one that did not want it the most, gets it.

A person that tries to minimize his responsibility the most for some ironic reason had to bear most of the responsibility

Sometimes position determine responsibility. Even if he did not want the throne, no one dares sits on the throne and no one is more qualified. 

One of the problem Death Monarch found is the containment of the forbidden areas. 

Even he could not fight all of the monsters in the forbidden areas if they were released. 

And Death Monarch knows that there are some crazy people in this world that just wanted to watch the world burns.

Of course, Death Monarch considers that his enemies would try to use the forbidden area monsters against him

But other than crazy people, nobody would be that suicidal. 

Everyone that survives the turbulent years after the Fall, knows the kind of damage and destruction that a powerful beast in the Heavenly rank could do to the world

By releasing such monster to the world, even if they somehow managed to kill Death Monarch, then the next one would be them. 

The White Dragon had burned millions of people alive. 

It freezes an entire mountain range and as it sails through the sky above that mountain range, the mountain range crumbles into glass, creating an avalanche of ice block the size of a city tumbling down, crushing even more people. 

The crumbling of such a large structure created earthquakes, land tremors and all around destruction 

And the White Dragon is not the only heavenly rank monsters that exist and wreak destruction all over the world in the day of the Fall.

Each of those forbidden area houses powerful beast and monsters that could wipe out millions if not billions of people in a matter of minutes.

When Death Monarch wrote the Article of Distribution, he was still in Disk Formation. 

Now, he might be confident to take on against the Heavenly rank monsters, but during that time, the threat of the Heavenly rank monster is the only threat to Death Monarch in the world

Even the Crime Alliance would not be that crazy to try to release the monster no matter how desperate they are and that is why they are never mentioned in any discussion when planning how to kill Death Monarch. 

If they ever had the plan to release the monster, they all would objected to it because they know they might be the first one that would be wiped out if they release such a monster. 

After all, they would be the first prey of such monster. No one knows whether these monster are intelligent or just a monster that operated in bloodlust, created to destroy the world

It is fortunate enough that they went to sleep after the Fall, no one wanted to be the sinner that woke them up

As for Void, even though it is rumored that he has a suit to counter his apparent lack of any body fortification method, nobody thinks that such suit would exempt him from dead if he were to open the seals that is put around the area of these monsters and wake them

That is why Death Monarch had never considered that Void would use the monster to attack him. 

And from what the world knows about Void is that he has a weird obsession with Death Monarch that no one understood.

Knowing him and his deranged mind, he would not be satisfied if he kills Death Monarch in such a way

But it still need protection from some crazy people like Rosulka in Russia. 

That crazy woman once tried to break the seal of one of the forbidden areas so that the monster could destroy the world

If not for Katarina quick attempt at dismantling Rosulka action, the world would have to mobilize all forces of the Seven Great Powers to try to kill the monster

Since that time, most of the seven great powers enhanced their security in the forbidden areas and each great powers is disallowed from trying to research anything around the forbidden area. 

All of this is a precaution for fearing that it might trigger something and woke the beast.
