This understanding does not merely originate from herself, but from the Forest Queen Melikai.
Gaven seriously recalled the future development of the gods, and indeed it was like this.
It seems that the rise of the short-lived races in Felen is not simply due to their own development, but rather integrated with the needs of the gods.
Without the latter, the former would encounter obstacles everywhere during their rise, possibly even perishing midway.
The Nesserel Empire is such a case. Besides the now popular theory of destruction due to the Felen Demon Sunflower War, there's also a theory of divine conspiracy.
If the Nesserel Empire hadn't collapsed, how would the Nesserel Pantheon have completely disappeared? How would the new human gods led by Tempus have risen?
Conversely, one could also understand that the g0ds of the Nesserel Pantheon were defeated, leading to the complete collapse of the Nesserel Empire.
