After Geth'xun fell into Deepholm, he corrupted the stone troggs that became known as the Felrock. They attacked the area, subduing drakes on the ground. Aeosera, however, refused to leave her eggs. Therazane sent the Farseer of the Earthen Ring to rescue the stone drakes, kill the corrupted troggs, and reassemble fallen Opalescent Guardians in order to carry Aeosera's eggs to safety. Opal Defenders were also throwing boulders onto the enemies.
