A long time ago, the "Civilization Game" was indeed a channel for communication between the gods.
Gods from different worlds and divine kingdoms, who wanted to cross world barriers to communicate, generally had to be at least at the Main God level to do so.
However, as time went by, the "Civilization Game" soon experienced a version upgrade.
First of all, not all gods are willing to expose themselves to the eyes of others.
Especially those gods who are inherently unsuitable for public exposure.
Their power comes from secrecy, from the dark, from death, from the eerie.
Thus, these gods came up with an idea — to support proxies.
Under every god, there is an Apostle belonging to them.
These Apostles might be mortals, might be demigods, or might even be True Gods.
Allowing Apostles under them, who are qualified to enter the "Civilization Game," to replace themselves in showing up, is indeed a great method.
