Since the flood wiped out civilization, and the mortal realm was in turmoil, countless springs and autumns have passed over the land.
To the deities, this wasn't an excessively long period, but for humans, it had already become an era too significant to ignore. It was long enough for a newborn to grow into adulthood, long enough for their migrating paths to traverse mountains and seas, and long enough for mortals to establish new institutions during the process.
However, this time, there was no Prometheus to guide them, and the gods likewise did not interfere in this process. Except for the followers of the Goddess of Hearthfire bringing the knowledge of the old era under the divine will, the new generation of humans was entirely in a state of natural growth.
