Taraza had listened secretly to the previous day's session between Sheeana and Odrade.

What was I listening for?

Young girl and teacher had been out here in the roof garden, facing each other on two benches, a portable Ixian damper hiding their words from anyone who did not have the coded translator. The suspensor-buoyed damper hovered over the two like a strange umbrella, a black disc projecting distortions that hid the precise movements of lips and the sounds of voices.

To Taraza, standing within the long meeting room, the tiny translator in her left ear, the lesson had occurred like an equally distorted memory.

When I was taught these things, we had not seen what the whores of the Scattering could do.

"Why do we say it's the complexity of sex?" Sheeana asked. "The man you sent last night kept saying that."

"Many believe they understand it, Sheeana. Perhaps no one has ever understood it, because such words require more of the mind than they do of the flesh."

"Why must I not use any of the things we saw the Face Dancers do?"

"Sheeana, complexity hides within complexity. Great deeds and foul ones have been done at the goading of sexual forces. We speak of 'sexual strength' and 'sexual energies' and such things as 'the overmounting urge of desire.' I don't deny that such things are observable. But what we are looking at here is a force so powerful that it can destroy you and everything you hold worthwhile."

"That's what I'm trying to understand. What is it the whores are doing wrong?"

"They ignore the species at its work, Sheeana. I think you can already sense this. The Tyrant certainly knew about it. What was his Golden Path but a vision of sexual forces at work recreating humankind endlessly?"

"And the whores don't create?"

"They mostly try to control their worlds with this force."

"They seem to be doing that."

"Ahhh, but what counterforces do they call forth?"

"I don't understand."

"You know about Voice and how it can control some people?"

"But not control everybody."

"Exactly. A civilization subjected to Voice over a long period develops ways of adapting to this force, preventing manipulation by those who use Voice."

"So there are people who know how to resist the whores?"

"We see unmistakable signs of it. And that is one of the reasons we are here on Rakis."

"Will the whores come here?"

"I'm afraid so. They want to control the core of the Old Empire because they see us as an easy conquest."

"Aren't you afraid they'll win?"

"They won't win, Sheeana. Depend on it. But they are good for us."

"How is that?"

Sheeana's tone echoed Taraza's own shock at hearing such words from Odrade. How much did Odrade suspect? In the next instant, Taraza understood and she wondered if the lesson was equally understandable to the young girl.

"The core is static, Sheeana. We have been almost at a standstill for thousands of years. Life and movement are 'out there' with the people of the Scattering who resist the whores. Whatever we do, we must make that resistance even stronger."

The sound of approaching 'thopters broke Taraza from her reverie of remembrance. The VIOs were arriving from Keen. Still at some distance, but the sound carried far in the clear air.

Odrade's teaching method was a good one, Taraza had to admit as she scanned the sky for a first glimpse of the 'thopters. Apparently they were coming in low and from the other side of the building. That was the wrong direction but perhaps they had taken the VIOs on a short excursion over the remains of the Tyrant's wall. Many people were curious about the place where Odrade had found the spice hoard.

Sheeana, Odrade, Waff, and Tulushan went back into the long meeting room. They had heard the 'thopters, too. Sheeana was anxious to show her power over the worms. Taraza hesitated. There was a laboring sound in the approaching 'thopters. Were they overloaded? How many observers had they brought?

The first 'thopter lifted over the penthouse roof and Taraza saw the armored cockpit. She recognized treachery even before the first beam arced out of the machine, slicing through her legs below the knees. She fell heavily against a potted tree, her legs completely severed. Another beam slashed out at her, slicing at an angle across her hip. The 'thopter swept over her in an abrupt roar of booster jets and banked away to the left.

Taraza clung to the tree, shunting the agony aside. She managed to cut off most of the bloodflow from her wounds but the pain was great. Not as great as the spice agony, though, she reminded herself. That helped but she knew she was doomed. She heard shouts and the multiple sounds of violence all around the museum now.

I have won! Taraza thought.

Odrade darted from the penthouse and bent over Taraza. They said nothing but Odrade showed that she understood by putting her forehead to Taraza's temple. It was the ages-old cue of the Bene Gesserit. Taraza began pouring her life into Odrade - Other Memories, hopes, fears... everything.

One of them might yet escape.

Sheeana watched from the penthouse, staying where she had been ordered to wait. She knew what was happening out there in the roof garden. This was the ultimate mystery of the Bene Gesserit and every postulant was aware of it.

Waff and Tulushan, already out of the room when the attack came, did not return.

Sheeana shuddered with apprehension.

Abruptly, Odrade stood and ran back into the penthouse. There was a wild look in her eyes but she moved with purpose. Leaping up, she gathered glowglobes, grabbing them in bundles by their toggle cords. She thrust several bundles into Sheeana's hands and Sheeana felt her body grow lighter with the lift of the globes' suspensor fields. Trailing more clusters of the globes beyond their field range, Odrade hurried across to the narrow end of the room where a grill in the wall indicated what she sought. With Sheeana's help, she lifted the grill out of its slots, revealing a deep airshaft. The light of the clustered glowglobes showed rough walls inside.

"Hold the globes close to get the maximum field effect," Odrade said. "Push them away to lower yourself. In you go."

Sheeana clutched the toggle cords in a sweaty hand and hopped over the sill. She let herself fall, then fearfully clutched the globes close. Light from above told her Odrade was following.

At the bottom, they emerged into a pump room, the susurrations of many fans a background for the sounds of violence from outside.

"We must get to the no-room and then to the desert," Odrade said. "All of these machinery systems are interconnected. There will be a passage."

"Is she dead?" Sheeana whispered.

"Yes."

"Poor Mother Superior."

"I am the Mother Superior now, Sheeana. At least temporarily." She pointed upward. "Those were the whores attacking us. We must hurry."
