The Legend of the Bapharian Divine

Long ago, the Bapharian Divine who ruled Regnus vanished, causing humanity to lose its technological foundation and fall into decline.
As civilization neared collapse, divine emissaries came forth with the "Oracle."
This gave rise to the Bapharian Creed, guiding humanity's rebirth.

Today, people know the Divine were simply another race resembling humans. Yet most still hold them in deep reverence.
