Wrath of the Righteous
Azlant is a lost continent in the Arcadian Ocean that was the first center of human culture on Golarion. Azlanti society and culture grew by leaps and bounds until their arrogant leaders began to think of themselves as superior to the gods. In retribution, the gods sunk the entire continent and condemning Golarion to thousands of years of darkness. Now all that remains of the once-mighty continent are a string of islands and atolls spread across a large swath of the mid-Arcadian; they are the only parts of the continent still above sea level.
Aroden was once one of the immortal Azlanti people, and somehow escaped from the sinking continent. He traveled Golarion for centuries seeking a way to free the world from the darkness that enshrouded it.
