 Nonetheless, the bloodline manipulations of the Bene Gesserit produce a supremely intelligent and perceptive killer in Fenring, who later serves as Emperor Shaddam's chief counselor.As related in "God Emperor of Dune" (1981), Quintinius Violet Chenoeh, specially trained as an oral recorder, is sent (with Tawsuoko) by Syaksa to Arrakis on a fact-gathering mission in 13,725 A.G. She is invited to converse with the God Emperor himself, and he is uncharacteristically indulgent of her questions and somewhat generous with his own information, however cryptic.Emperor Leto tells Chenoeh that he plans to restore "outward spiritual freedom" for mankind, and then refers to Siona Atreides as his "achievement" (which the Sisterhood correctly interprets as being related to Leto's own breeding program).
