Would it be possible to write an encyclopeadia of Dune? I dont think it would be possible for the following reason. Shaddam,Paul and Leto II were the emperors of a million planets. Does anybody online or in the real world have time to catalogue all of these worlds. Also returning to the theme of this discussion, with one million planets is it possible that the empire is run and controlled from somewhere a little more central in the galaxy rather than from the end of an obscure spiral arm? With so many planets maybe thay found somewhere much better. ;D
