Aah! I see a small space in the murky waters. Everything has just become a little clearerIt's a prologue to Dune (as stated in the french edition), Lewis Orne and fellow psy talents are first experiment in a field which will lead to Guild Navigators. Lewis' mother and sisters are formind a women society and encouraging careful breeding. Ring a bell ? Beside compare how Lewis Orne's mother act with his fater, and compare it to Miles Teg's mother and Lady Fenring, or any Bene Gesserit in Dune. The pattern are there, not yet refined but still there.
