Era beginning/end
The departure of the gods from the ancient Kyonyita Sea, and the subsequent draining and desertification of the sea which caused it to become the Kyonyita Desert of today.
The Fall from Grace was the event which catalyzed the formation of the Kyonyita Desert, and which the Khangka people believe to be the great disgrace of their ancestors. In their greed and complacence, the ancient Khangka sea tribes failed to worship the Tagushana, which caused them to leave the earth and deprive the people of their many blessings. The sea drained to nothing and the Kyonyita became a toxic, unlivable wasteland, forcing the Khangka to live underground and pray for the return of the sea.
