I am beginning to suspect that kirk55555 is actually Brian Herbert...
Or one of the many "prequelites" (the polite form of that term; there is a much more rude form which I won't use here) who infest the Dunenovels forum and drive the Orthodox Herbertarians away for lack of intelligent conversation.
, how do you square Frank Herbert's assertion in Dune that Paul was born on Caladan with KJA/BH's nonsense that he was born on Kaitain? That was the first major bit of retconning that infuriated a lot of Dune readers. But unfortunately, it wasn't the last.
