The following brief dialogue is credited to a manuscript source called "The Welbeck Fragment." The reputed author is Siona Atreides. The participants are Siona herself and her father, Moneo, who was (as all the histories tell us) a majordomo and chief aide to Leto II. It is dated at a time when Siona was still in her teens and was being visited by her father at her quarters in the Fish Speakers' School at the Festival City of Onn, a major population center on the planet now known as Rakis. According to the manuscript identification papers, Moneo had visited his daughter secretly to warn her that she risked destruction.
SIONA: How have you survived with him for so long a time, father? He kills those who are close to him. Everyone knows that.
MONEO: No! You are wrong. He kills no one.
SIONA: You needn't lie about him.
MONEO: I mean it. He kills no one.
SIONA: Then how do you account for the known deaths?
MONEO: It is the Worm that kills. The Worm is God. Leto lives in the bosom of God, but he kills no one.
SIONA: Then how do you survive?
MONEO: I can recognize the Worm. I can see it in his face and in his movements. I know when Shai-Hulud approaches.
SIONA: He is not Shai-Hulud!
MONEO: Well, that's what they called the Worm in the Fremen days.
SIONA: I've read about that. But he is not the God of the desert.
MONEO: Be quiet, you foolish girl! You know nothing of such things.
SIONA: I know that you are a coward.
MONEO: How little you know, You have-never stood where I have stood and seen it in his eyes, in the movements of his hands.
SIONA: What do you do when the Worm approaches?
MONEO: I leave.
SIONA: That's prudent. He has killed nine Duncan Idahos that we know about for sure.
MONEO: I tell you he kills no one!
SIONA: What's the difference? Leto or Worm, they are one body now.
MONEO: But they are two separate beings-Leto the Emperor and The Worm Who Is God.
SIONA: You're mad!
MONEO: Perhaps. But I do serve God.
