With a silent Waff about twenty paces ahead of them, Odrade and Sheeana walked down a weed-fringed road beside a spice-storage yard. All of them wore new desert robes and glistening stillsuits. The gray nulplaz fence that defined the yard beside them held bits of grass and cottony seedpods in its meshes. Looking at the seedpods, Odrade thought of them as life trying to break through a human intervention.

Behind them, the blocky buildings that had arisen around Dar-es-Balat baked in the sunlight of early afternoon. Hot dry air burned her throat when she inhaled too quickly. Odrade felt dizzy and at war within herself. Thirst nagged at her. She walked as though balanced on the edge of a precipice. The situation she had created at Taraza's command might explode momentarily.

How fragile it is!

Three forces balanced, not really supporting each other but joined by motives that could shift in an instant and topple the whole alliance. The military people sent by Taraza did not reassure Odrade. Where was Teg? Where was Burzmali? For that matter, where was the ghola? He should be here by now. Why had she been ordered to delay matters?

Today's venture would certainly delay matters! Although it had Taraza's blessing, Odrade thought this excursion into the desert of the worms might be a permanent delay. And there was Waff. If he survived, would there be any pieces for him to pick up?

Despite the healing applications of the Sisterhood's best quicknit amplifiers, Waff said his arms still ached where Odrade had broken them. He was not complaining, merely providing information. He appeared to accept their fragile alliance, even the modifications that incorporated the Rakian priestly cabal. No doubt he was reassured that one of his own Face Dancers occupied the High Priest's bench in the guise of Tuek. Waff spoke forcefully when he demanded his "breeding mothers" from the Bene Gesserit and, consequently, withheld his part of their bargain.

"Only a small delay while the Sisterhood reviews the new agreement," Odrade explained. "Meanwhile..."

Today was "meanwhile."

Odrade put aside her misgivings and began to enter the mood of this venture. Waff's behavior fascinated her, especially his reaction on meeting Sheeana: quite plainly fearful and more than a little in awe.

The minion of his Prophet.

Odrade glanced sideways at the girl walking dutifully beside her. There was the real leverage for shaping these events into the Bene Gesserit design.

The Sisterhood's breakthrough into the reality behind Tleilaxu behavior excited Odrade. Waff's fanatic "true faith" gained shape with each new response from him. She felt fortunate just to be here studying a Tleilaxu Master in a religious setting. The very grit under Waff's feet ignited behavior that she had been trained to identify.

We should have guessed, Odrade thought. The manipulations of our own Missionaria Protectiva should have told us how the Tleilaxu did it: keeping themselves to themselves, blocking off every intrusion for all of those plodding millennia.

They did not appear to have copied the Bene Gesserit structure. And what other force could do such a thing? It was a religion. The Great Belief!

Unless the Tleilaxu are using their ghola system as a kind of immortality.

Taraza could be right. Reincarnated Tleilaxu Masters would not be like Reverend Mothers - no Other Memories, only personal memories. But prolonged!

Fascinating!

Odrade looked ahead at Waff's back. Plodding. It appeared to come naturally to him. She recalled that he called Sheeana "Alyama." Another confirming linguistic insight into Waff's Great Belief. It meant "Blessed One." The Tleilaxu had kept an ancient language not only alive but unchanged.

Did Waff not know that only powerful forces such as religions did that?

We have the roots of your obsession in our grasp, Waff! It is not unlike some that we have created. We know how to manipulate such things for our own purposes.

Taraza's communication burned in Odrade's awareness: "The Tleilaxu plan is transparent: Ascendancy. The human universe must be made into a Tleilaxu universe. They could not hope to achieve such a goal without help from the Scattering. Ergo."

The Mother Superior's reasoning could not be denied. Even the opposition within that deep schism that threatened to shatter the Sisterhood agreed. But the thought of those human masses in the Scattering, their numbers exploding exponentially, produced a lonely sense of desperation in Odrade.

We are so few compared to them.

Sheeana stooped and picked up a pebble. She looked at it a moment and then threw it at the fence beside them. The pebble sailed through the meshes without touching them.

Odrade took a firmer grip on herself. The sounds of their footsteps on the blown sand that drifted across this little-used roadway seemed suddenly over-loud. The spindly causeway leading out over the Dar-es-Balat ring-qanat and moat lay no more than two hundred paces ahead at the end of this narrow road.

Sheeana spoke: "I am doing this because you ordered it, Mother. But I still don't know why."

Because this is the crucible where we test Waff and, through him, reshape the Tleilaxu!

"It is a demonstration," Odrade said.

That was true. It was not the whole truth, but it served.

Sheeana walked head down, gaze intent on where she placed each step. Was this how she always approached her Shaitan? Odrade wondered. Thoughtful and remote?

Odrade heard a faint thwocking sound high up behind her. The watchful ornithopters were arriving. They would keep their distance, but many eyes would observe this demonstration.

"I will dance," Sheeana said. "That usually calls a big one."

Odrade felt her heartbeat quicken. Would the "big one" continue to obey Sheeana despite the presence of two companions?

This is suicidal madness!

But it had to be done: Taraza's orders.

Odrade glanced at the fenced spice yard beside them. The place appeared oddly familiar. More than deja vu. Inner certainty informed by Other Memories told her this place remained virtually unchanged from ancient times. The design of the spice silos in the yard was as old as Rakis: oval tanks on tall legs, metal and plaz insects waiting stilt-legged to leap upon their prey. She suspected an unconscious message from the original designers: Melange is both boon and bane.

Beneath the silos, a sandy wasteland where no growth was permitted spread out beside mud-walled buildings, an amoeba arm of Dar-es-Balat reaching almost to the qanat edge. The Tyrant's long-hidden no-globe had produced a teeming religious community that hid most of its activities behind windowless walls and underground.

The secret working of our unconscious desires!

Once more, Sheeana spoke: "Tuek is different."

Odrade saw Waff's head lift sharply. He had heard. He would be thinking: Can we conceal things from the Prophet's messenger?

Too many people already knew that a Face Dancer masqueraded as Tuek, Odrade thought. The priestly cabal, of course, believed they were giving the Tleilaxu enough netting in which to snare not only the Bene Tleilax but the Sisterhood as well.
