Chapter 16

Overview

Teg enforces Taraza’s limits on Schwangyu’s access to Duncan while wrestling with anxiety. A vivid memory of Taraza’s teachings on melange, doubt, prescience, and Ixian belief triggers an amplified Mentat breakthrough. Teg realizes Taraza and Odrade have primed him for an extraordinary, risky performance that could shape the Sisterhood’s fate.

Summary

After Taraza’s departure from Gammu, Miles Teg reorganizes Keep procedures to keep Schwangyu away from the Duncan ghola, following Taraza’s strict order: Schwangyu may observe but not touch. Despite filling his schedule, Teg experiences unsettling anxiety and finds it difficult to enter Mentat mode.

Triggering a long-buried memory, Teg recalls a post-crisis conversation with Taraza aboard her no-ship. Over a melange-rich stimulant, Taraza speaks candidly about Bene Gesserit “heresy,” the effects of spice, and the strengths of Teg’s philosophical doubt. She links the Bene Gesserit’s spice agony to Zensunni s’tori, framing doubt as essential and warning against belief’s stagnation.

The discussion turns to prescience—whether Maud’dib and the Tyrant predicted or created the future—and to how belief shapes perception, even among Ixian scientists who design experiments that confirm their assumptions. The exchange reshapes Teg’s understanding of his mother, the Sisterhood, and the burden of foreknowledge.

Snapping back to the present, Teg feels restored to Mentat clarity. The remembered lesson catalyzes a “magical” cognitive expansion in which he discards limiting beliefs and perceives patterns more transparently. Recognizing the design behind this, Teg understands that Taraza—and by extension Odrade—have deliberately amplified him for a daunting assignment that could determine the Bene Gesserit’s survival.
