The demorgorg system is dangerous to both entities despite all the advancements that Legion has made to streamline the process. It is not as dangerous as the situation Helios was in when he tried to break through and assimilate the Celestial power of the sun god, but these people are no Helios.
Helios was trying to become a transcendent while absorbing the divine power of a Celestial. The giants on the other hand are already transcendents but the tree father had to make the process more dangerous to the demons for the giants of order to have this level of survival.
Now if the danger to both giants of order and demons is eliminated completely, the demorgorg system will still become obsolete because it has a limit of power. The highest rank achievable for the demorgorgs is five stars. That is the equivalent of a titan of law and it requires a living demon lord to be sealed within a transcendent.
The demorgorg system cannot seal a demon king. That is just impossible. The divine power of a Celestial cannot bind a demon king without a violent reaction. This reaction will turn the body of the giant of order into a battlefield and kill them.
If it were possible to seal a demon king, it would require a massive cost in divine energy and the constant assistance of Authority. That means the tree father will only be able to maintain a single six-star demorgorg and he will have most of his power diverted to keep the demon king sealed as long as the six-star demorgorg exists.
That is a foolish trade because a six-star demorgorg will only have the strength of a Sovereign at most. This is because the seal will have to cripple the demon king to reduce its resistance and use it which will lead to a reduction in its output.
Already, the cost of a five-star demorgorg is prohibitive. Demon lords are unique. There can be only one in an abyssal plane. That further limits the maximum amount of five-star demorgorgs that can be created. So there is a limit to the quantity and quality of power even if there is an unlimited amount of transcendents and demons.
As it is, the only five-star demorgorg in existence is Hak. A demon lord is rare but it wasn't difficult for Aeternus to acquire some. But it was extremely difficult for giants of order to assimilate the lowest rank of demon lord.
The giants of order are only transcendents after all. It is already a miracle that someone managed to assimilate a weak demon lord. Powerful demon lords like Beelta with half-divine stats are impossible to assimilate by the current giants of order.
The good news is that no demon lords went to waste during the process of assimilation. The assimilation didn't endanger them enough before the giants of order died.
Even four-star demorgorgs who have spent thousands of years with demon nobles sealed within them and have become used to it cannot withstand the pressure of a demon lord. A demon lord is connected to an abyssal plane after all. The only one that succeeded had a lot of help from the tree father.
Hak was and is still being reinforced by the divine power of the tree father the same way the tree father assisted Helios during his breakthrough. Except he isn't using any of his divine life energy. The divine energy of order is resisting the energy well of the abyssal plane and is preventing Hak from being overwhelmed.
This can be done for other demorgorgs too. More five-star demorgorgs can be created that way. In fact, the tree father can sacrifice some of his divine power to empower the giants instead of using demons, but what use will the demorgorgs be then?
If they need his help to have power, then it is better for the tree father to keep his power for himself and use it when needed. It will be a waste to go through that route when that divine power can be used to assist Legion. Even if they go for this inefficient method, the best that they can achieve is still the five-star demorgorg.
They have no way to seal demon kings and no way to give giants of order access to their Authority without it being detrimental to Legion. That means they won't have any Sovereign level forces.
The demorgorgs are supposed to be useful for protecting the plane and assisting the realm in the era of conquest. If they don't have Sovereigns then they can't even attempt to achieve those objectives. That's why the Tree father and Helios decided it was time to create a better system.
-------
The tree father and Helios worked while their enemies also worked in the background. Tanya reached the borders of the kingdom of life after making her preparations. The border of the only stable kingdom is very apparent. It is stable because it is not at the threat of being destroyed by demons.
The plane has recovered nicely since the world war and the demon war that occurred after. The demons have sunk down to the depths of ruins where they hide. But some come up occasionally to feed on poor souls.
Any settlement outside the borders of the kingdom of life can be destroyed at any time by demons. There is no helping it because the only forces that can resist them are the demorgorgs and guardians of the god-king.
She stands before the border now. It is unmistakable. It is not an arbitrary line in the ground on a map. It doesn't shift or change across seasons and political fluctuations. The border is visible and indisputable. It is there for everyone to see because it has the might of the god-king to enforce it.
The translucent barrier that she is standing in front of marks the beginning of the kingdom of life. Any demon that sees it knows it is a no-go area. Rebels, like her, also no that they can't trespass unnoticed. That is until today.
