The so-called Pantheon was not simply the temple of a single god. To be precise, its nature was the same as the Alliance of Divine Academies. It was an alliance of a group of temples.
Under normal circumstances, the temples would repel each other. Many of them even had irreconcilable grudges because of the grudges between gods.
Even if there was no deep hatred, they would not be too harmonious because of the fight for believers, let alone form a substantial alliance.
However, the Divine Kingdom on land was different.
Because of the war between the gods and the humans, the power of the various temples on the land was almost completely destroyed. Although they were rebuilt one after another, under the constraints of the Supreme Oracle, the power that the gods could project was very limited, and the speed of developing believers was greatly limited.
