Concept and theme has remained the same in this whole series only faces of new heroes and villains get introduced after some time. And that has been the idea behind the Wheel of the Time i.e changes of eras brings in new faces but the intensity of their struggle remains the same. Changes are in order after the leaking of the truth about the lord of the Black Tower. Mazrim Taim i.e the leader of the Black Tower has been lying to the people of the land and everyone around for decades and now everyone knows the reason as well. With the revelation of truth the scene has totally changed. Queen Alliandre also never expected that her end would be so much drastic because has been locked inside a cage while the keys are thrown as far as possible. Robert Jordan introduces the Daughter of the Nine Moons too in all her physical appeal which can charm anyone.
But war is at hand and no one holds the supreme power to have a strong control on the battle ground. The Eye of the World and The Great Hunt started things in the voice of Kate Reading and Michael Kramer. In those initial parts the author told us about the rotation of the Wheel of Time. In this ninth part also the time has come for the Wheel to rotate once again and change heroes into myths. New faces will take the place of old one but the process is not that easy because the old ones are not going down very easily this time i.e they are ready to fight and shed blood.
