Pantheon:
It is a devastating tale that you will soon learn. Once one of the seals that bound the Goddess of Destruction was released, many catastrophic events followed. Such was the case with the fall of Ye Sagira.
Scholars including myself were dispatched to study the ruins. Soon all other races came as well.
I cannot recall the event fully, but Theodore knows more about when the migration of all the races came to Talking Island Village. You should speak with him.
