Foundation has made a point in showing that the once all-powerful Empire is crumbling. Cracks are showing not only in the amount of planets that have broken away from the Empire, but also between the Cleons themselves. Queen Sareth of the Cloud Dominion is shifting the balance of power on Trantor, and now she has discovered one of the biggest secrets of the Empire. This discovery can help her gain further power over Brother Day and can even lead to her bringing down the Empire.
