However, the God Emperor's hatred was profound, the result of his own addiction to the company of the Duncan gholas, a need he never successfully conquered despite at least one serious attempt to do so. While the numerous particular actions and products generated significant ill will, it is more likely that the TteUaxu were generally loathed for a more primordial reason. Their genetic manipulations manned life and nature. The Bene Gesserit could be tolerated, even admired, for their pretension at improving humanity, but the Bene Tleilax's distortions only inspired primal horror. S.T. and R.S.

One of an elect group of Reverend Mothers adept in the ways of truthtrance and able to discern and identify falsehood, deceit, and insincerity. The hypnotic or ecstatic state called truthtrance was commonly induced by drug compounds known as "awareness spectrum" narcotics. However, recent evidence suggests that some experienced Trutfisayers could self-induce oiithtrance without the aid of any stimulants merely by the power of autosuggestion. What is indisputable is mat narcotic or drag preparations entirely benign to the Iruthsayer could prove fatal for anyone else inclined to secure the magic properties attributed to them. Most eminent among celebrated Truthsavers was the Reverend Mother Gams Helen Mohiarn. Justly renowned both as practitioner of the art of truthtrance and as historian and analyst of the role of the Iruthsayer since its inception just after the Butlerian Jihad, Reverend Mother Gates Helen's service as Truthsayer to the Padishah Emperor Shaddam IV offered her a unique, even inspired, vantage point from which to consider the office of Truthsayer, its function, purpose, and value. The treatise she wrote on the subject was respected, above all, for the authoritative simplicity and elegance of its style and the humility of tone it exhibited in its treatment of so exalted a subject. Her Prolegomena to the Sacred History of the Council of Nine is deeply indebted to the Sattva Codex, one of the priceless documents committed to the once secret archives of the Bene Gesserit. The Sattva Codex is a truly extraordinary document with a wealth of exhaustive detail and a breadth of continuity supplied by its addenda and appendices dating to the conclusion of the Butlerian Jihad. The original document constitutes a concise chronicle outlining the origin, purpose, philosophy, and character of the Holy Council of Nine as it evolved under the inspired leadership of Mother Jehanne.
