During the War of Power, there were two plans as to how to defeat the Shadow; one was the plan supported by Latra Posae Decume, a female Aes Sedai of great strength and prominence to use the ter'angreal access keys to wield the One Power through the giant sa'angreal in order to defeat the forces of the Shadow and to erect a barrier around Shayol Ghul until a way to deal with the problem could be devised. Using the statues directly was impossible due to the massive amounts of the One Power and due to the difficulty of transporting them to the field of battle.
