Pyramid of Hazkar
A Dance with Dragons
The pyramid of Hazkar is attacked by Rhaegal after he and Viserion are unleashed upon Meereen. Rhaegal attempts to make his lair atop the pyramid, killing the slavers who are foolish enough to object. The smoking ruin eventually collapses, however, Rhaegal ends up making his lair at the pyramid of Yherizan.
Shortly after Prince Quentyn Martell dies in Daenerys Targaryen's bed, Ser Barristan Selmy stands on the highest step of the Great Pyramid and notices whips of smoke still rising from the smoldering ruin of the pyramid of Hazkar.
