Earthquake of 715
From RocksfallWiki
The earthquake of 715 was a major earthquake that struck just east of the city of Omba. Still recovering from the Great Flood of 702, the city was further damaged, including the city walls and several temples containing precious ancient Ancestors. It is estimated that 400 people died and over 150 ancestors were permanently lost due to the earthquake. This further destabilized the city and led to the Bone War a few years later.
