As though projected into his mind and outlined there in fire, he found his entire Mentat-attention fixated on the Zensunni admonition that was taught to every beginning student in the Mentat School:

By your belief in granular singularities, you deny all movement - evolutionary or devolutionary. Belief fixes a granular universe and causes that universe to persist. Nothing can be allowed to change because that way your non-moving universe vanishes. But it moves of itself when you do not move. It evolves beyond you and is no longer accessible to you.

"The oddest thing of all," Taraza said, sinking into tune with this mood she had created, "is that the scientists of Ix cannot see how much their own beliefs dominate their universe."

Teg stared at her, silent and receptive.

"Ixian beliefs are perfectly submissive to the choices they make on how they will look at their universe," Taraza said. "Their universe does not act of itself but performs according to the kinds of experiments they choose."

With a start, Teg came out of the memories and awoke to find himself in the Gammu Keep. He still sat in the familiar chair in his workroom. A glance around the room showed nothing moved from where he had put it. Only a few minutes had passed but the room and its contents no longer were alien. He dipped into and out of Mentat mode. Restored.

The smell and taste of the drink Taraza had given him so long ago still tingled on his tongue and in his nostrils. A Mentat blink and he knew he could call up the scene entire once more - the low light of shaded glowglobes, the feeling of the chair beneath him, the sounds of their voices. It was all there for replay, frozen into a time-capsule of isolated memory.

Calling up that old memory created a magical universe where his abilities were amplified beyond his wildest expectations. No atoms existed in that magical universe, only waves and awesome movements all around. He was forced there to discard all barriers built of belief and understanding. This universe was transparent. He could see through it without any interfering screens upon which to project its forms. The magical universe reduced him to a core of active imagination where his own image-making abilities were the only screen upon which any projection might be sensed.

There, I am both the performer and the performed!

The workroom around Teg wavered into and out of his sensory reality. He felt his awareness constricted to its tightest purpose and yet that purpose filled his universe. He was open to infinity.

Taraza did this deliberately! he thought. She has amplified me!

A feeling of awe threatened him. He recognized how his daughter, Odrade, had drawn upon such powers to create the Atreides Manifesto for Taraza. His own Mentat powers were submerged in that greater pattern.

Taraza was demanding a fearful performance from him. The need for such a thing both challenged and terrified him. It could very well mean the end of the Sisterhood.

"How is it that you can order the priests around?" Sheeana asked. "This is their place."

Odrade answered casually but picked her words to fit the knowledge she knew Sheeana already possessed: "The priests have Fremen roots. They've always had Reverend Mothers somewhere near. Besides, child, you order them around, too."

"That's different."

Odrade suppressed a smile.

Little more than three hours had passed since her assault force had broken the attack on the temple complex. In that time, Odrade had set up a command center in Sheeana's quarters, carried on the necessary business of assessment and preliminary retaliation, all the while prompting and observing Sheeana.

Simulflow.

Odrade glanced around the room she had chosen as command center. A scrap of Stiros' ripped garments still lay near the wall in front of her. Casualties. The room was an oddly shaped place. No two walls parallel. She sniffed. Still a residual smell of ozone from the snoopers with which her people had assured the privacy of these quarters.

Why the odd shape? The building was ancient, remodeled and added to many times, but that did not explain this room. A pleasantly rough texture of creamy stucco on walls and ceiling. Elaborate spice-fiber hangings flanked the two doors. It was early evening and sunlight filtered by lattice shades stippled the wall opposite the windows. Silver-yellow glowglobes hovered near the ceiling, all tuned to match the sunlight. Muted street sounds came through the ventilators beneath the windows. The soft pattern of orange rugs and gray tiles on the floor spoke of wealth and security but Odrade suddenly did not feel secure.

A tall Reverend Mother came from the adjoining communications room. "Mother Commander," she said, "the messages have been sent to Guild, Ix, and Tleilaxu."

Odrade spoke absently. "Acknowledged."

The messenger returned to her duties.

"What are you doing?" Sheeana asked.

"Studying something."

Odrade pursed her lips in thought. Their guides through the temple complex had brought them along a maze of hallways and stairs, glimpses of courtyards through arches, then into a splendid Ixian suspensor-tube system, which carried them silently to another hallway, more stairs, another curved hallway... finally, into this room.

Once more, Odrade swept her gaze around the room.

"Why are you studying this room?" Sheeana asked.

"Hush, child!"

The room was an irregular polyhedron with the smaller side to the left. About thirty-five meters long, half that at the widest. Many low divans and chairs in various degrees of comfort. Sheeana sat in queenly splendor on a bright yellow chair with wide soft arms. Not a chairdog in the place. Much brown and blue and yellow fabric. Odrade stared at the white lattice of a ventilator above a painting of mountains on the wider end wall. A cool breeze came through the ventilators below the windows and wafted toward the ventilator above the painting.

"This was Hedley's room," Sheeana said.

"Why do you annoy him by using his first name, child?"

"Does that annoy him?"

"Don't play word games with me, child! You know it annoys him and that's why you do it."

"Then why did you ask?"

Odrade ignored this while continuing her careful study of the room. The wall opposite the painting stood at an oblique angle to the outer wall. She had it now. Clever! This room had been constructed so that even a whisper here could be heard by someone beyond the high ventilator. No doubt the painting concealed another airway to carry sounds from this room. No snooper, sniffer, or other instrument would detect such an arrangement. Nothing would "beep" at a spying eye or ear. Only the wary senses of someone trained in deception had winkled it out.

A hand signal summoned a waiting acolyte. Odrade's fingers flickered in silent communication: "Find out who is listening beyond that ventilator." She nodded toward the ventilator above the painting. "Let them continue. We must know to whom they report."

"How did you know to come and save me?" Sheeana asked. The child had a lovely voice but it needed training, Odrade thought. There was a steadiness to it, though, that could be shaped into a powerful instrument.

"Answer me!" Sheeana ordered.

The imperious tone startled Odrade, arousing quick anger, which she was forced to suppress. Corrections would have to be made immediately!

"Calm yourself, child," Odrade said. She pitched the command in a precise tenor and saw it take effect.

Again, Sheeana startled her: "That's another kind of Voice. You're trying to calm me. Kipuna told me all about Voice."
