As for the realm beyond the natural authority... this is the blind spot of the primordial gods. Therefore, aside from simplifying some Common Divine Arts through the omniscient nature of Divine Power with the assistance of Athena, the 'Sacred Power models' mastered by different deities often exhibited vast differences, with various distinct functions.
When this power spread into the Mortal Realm, such differences also indirectly confirmed the absoluteness of the different deities within their own domains of authority, leading to a bias in the compilation of many scriptures. Of course, there were mortals who thus began to question the greatness of the deities, but this did not cause any significant impact.
After all, all gods were like this, and there had never been any being, god or otherwise, who proclaimed themselves omniscient and omnipotent; thus, these speeches were nothing but fleeting and hardly remembered by anyone as having existed.
In any case, Sacred Power and Divine Arts were integrated into the world, and simply after a few generations, they seemed to become a matter of natural course, understood and accepted by humans. Even the deities themselves gradually got used to this convenient form of energy.
However, there was an additional side story in the midst. Atop Mount Olympus, the Divine King who had also learned of the birth of Divine Arts seemed especially surprised, even once claiming that he had discovered this special system but had not yet had the chance to inform the other gods.
However, concerning his declaration, the gods only verbally agreed, while few truly believed him in their hearts.
After all, Zeus had never shown any particular talent in creation and invention in the past.
They would rather believe it was related to the former Goddess of Wisdom, Metis, than think the Divine King could have developed such a thing. After all, they were well aware that power and wisdom are not equivalent.
If she wanted to make trouble, let her. He could not break the vow he had made, but if all the other deities showed dissatisfaction, that would have nothing to do with him.
When the day came, someone would surely put pressure on Hades, who resided in the Underworld. After all, the consequences he caused affected the interests of all deities.
...
Mortal Realm.
If one were to draw a central axis for Chaos Terrain, the once Mount Othrys would undoubtedly be on that midline. It supported heaven and earth, separating north, south, east, and west; even Mount Olympus of today could not compare to it.
And if another axis were drawn for the Eastern Lands, then Olympus would be located slightly towards the northeast direction; as for the human settlements, they would be even further east.
The closer to the Mount of the Gods, the more concentrated the humans, because this was the direction of the fourth generation of human migration. After the great flood, they moved from west to east across the Eastern Lands, seeking suitable places to settle.
The closer to Mount Olympus, the shorter the migration distance and the longer the time for settling and multiplying; they held a distinct advantage in both population and culture.
Of course, this also often meant that there was more divine attention, and it was common for a city to have temples dedicated to seven or eight deities.
