There has been speculation that the thirteen towers that Egwene dreams about in Chapter 3, the Amyrlin’s Anger, represent the original thirteen Forsaken. As the towers/Forsaken fall/die, the remain towers/Forsaken become stronger. There is some vaility to this theory. However in a reread, I noticed the following reference to the chaos in Seanchan and to thirteen towers:

Chapter 1: Apples First: “At the base of the foothills, the wind turned eastward, passing an open plan kept free of trees and scrub by the soldier’s axe The killing field surrounded thirteen fortresses, tall and cut entirely from unpolished black marble, their blocks left rough-hewn to give them a primal feeling of unformed strength. These were towers meant for war. By tradition they were unoccupied. How long that would last-how long tradition would be remembered in a continent in chaos-remained to be seen?

Chapter 3: Amyrlin’s Anger: “All was dust around her, and thirteen black towers rose in the distance beneath a tar sky. One fell , and then another, crashing to the ground. As they did, the ones that remained grew taller and taller. The ground shook as several more towers fell. Another tower shook and cracked, collapsing most of the way to the ground-but then, recovered and grew tallest of all.

Could the thirteen towers in Egwene’s dream refer instead to the pending Seanchan attack on the White Tower?
