This is a galaxy created by God, a system established by God. From being alone to the establishment of the Holy See, in the face of disasters given by time, the preparations given by God are not enough.
The races under the gods are completely unaware of the coming disaster. They only see the divine system, and they spend their whole lives fighting for it to become the existence that rules everything.
God was so helpless that she could only turn to the "god envoy" who came and prayed that he could change the status quo so that these races could continue to survive.
