The city, located on the north end of the Isle of Cedars, vanished in a heartbeat during the Doom of Valyria. The ancient brick walls and stepped pyramids of the slaver port of Ghozai suffered the same fate as Velos on the south end of the island - a wall of water 300 feet high descended on the city, drowning hundreds of thousands of men, women, and children, leaving none to tell the tale. The broken pyramids are currently infested with monkeys.
A Dance with Dragons
Victarion Greyjoy orders the Iron Fleet to chase a trading galley, the Ghiscari Dawn, which tries to escape by drawing close to the Isle of Cedars. By the time Lamentation comes alongside its prey, both ships are so close to the haunted ruins of Ghozai that they can hear monkeys chattering as the first light of dawn washes over the city's broken pyramids.
