Sandworms of Dune - Entry #6

     "The Golden Path".  Always questions about it since Leto II never divulged what it was and where it led.  Each of our most important characters have struggled with this, curious and questioning.  As Murbella is trying to map out a strategy for the humans to fight the machines, she too struggles with it:

     If the Tyrant's prescience was so formidable, how could he not have foreseen the existence of the great machine empire, no matter how far away it was?  How could the God Emperor not have known that another titanic conflict awaited humankind?  She felt a faint shudder.  Or had he, and everything was playing out exactly as the Tyrant planned?

(Sandworms of Dune, p. 342)

     By the way, notice the use of "humankind" not "mankind".  Love that.
