Canon:Istar

Istar was a city founded after a war between three families.The city grew and developed into an empire of its own, and the Kingpriest took residence here in grand palaces. The Kingpriest grew to believe he was a god, and his hubris called down the wrath of the true gods. Their power was seen in the Cataclysm. The Cataclysm destroyed the Empire of Istar, sending it to the bottom of the ocean. As the waters covered it, the Blood Sea of Istar was formed.
