It is also at this time Azief realizes something.
When he is inside the Crystal Palace and comprehending the Etherna inheritance, he must have been shielded from the outside world
In these twenty years, the people grows, the world powers strengthened their foundation, the rogue's faction that has been beaten in the last war recuperated
Everyone took these twenty years' time to all improve themselves.
And the Heavenly will in that span of twenty years had grown stronger
the stronger the people, the more the energy, the more people that died, the more powerful the Heavenly Will becomes.
And the Heavenly Will also wanted to take back the one third of His power and domain. There is a reason why sometimes people refers to Death Monarch as the heaven of earth
Because he controls one third of the Heavenly Will. That alone gives him all kinds of unfair advantage whine fighting on earth.
