The Sin attacks were the costliest natural disaster in the history of Spira. The attacks currently rank as the most intense Sin landfalling. Overall, over 9,000 people died in the disaster and subsequent floods, making it the deadliest Spiran attack ever. Total property damage estimates at $108 billion (gil), roughly four times the damage wrought by Sin during the Machina War. Sin caused severe destruction along the Zanarkand coast, much of it due to the flood surge and levee failure. Severe property damage occurred in coastal areas, with waters reaching 20–29 km from the beach. Sin attacked Zanarkand during a blitzball tournament, in which the stadium collapsed.
Maester in the church of Yevon Seymour responded,
“What happened in Zanarkand looked like the curse of Sin, in time if Zanarkand recovers and becomes the pristine city it can become it may in time be called a blessing. But at this time it’s called a curse.”
The Dream of the Fayth later rebuilt Zanarkand, creating the city directly from their memories.
