The Preacher lowered his head as though in prayer.

Alia felt herself shivering with awareness. Gods below! That voice! It had been cracked by years in the burning sands, but it could be the remnant of Paul's voice.

Once more The Preacher raised his head. His voice boomed out over the square where more people had begun to gather, attracted by this oddity out of the past.

"Thus it is written!" The Preacher shouted. "They who pray for dew at the desert's edge shall bring forth the deluge! They shall not escape their fate through powers of reason! Reason arises from pride that a man may not know in this way when he has done evil." He lowered his voice. "It was said of Muad'Dib that he died of prescience, that knowledge of the future killed him and he passed from the universe of reality into the alam al-mythal. I say to you that this is the illusion of Maya. Such thoughts have no independent reality. They cannot go out from you and do real things. Muad'Dib said of himself that he possessed no Rihani magic with which to encipher the universe. Do not doubt him."

Again The Preacher raised his arms, lifted his voice in a stentorian bellow: "I warn the priesthood of Muad'Dib! The fire on the cliff shall burn you! They who learn the lesson of self-deception too well shall perish by that deception. The blood of a brother cannot be cleansed away!"

He had lowered his arms, found his young guide, and was leaving the square before Alia could break herself from the trembling immobility which had overcome her. Such fearless heresy! It must be Paul. She had to warn her guards. They dared not move against this Preacher openly. The evidence in the square below her confirmed this.

Despite the heresy, no one moved to stop the departing Preacher. No Temple guard leaped to pursue him. No pilgrim tried to stop him. That charismatic blind man! Everyone who saw or heard him felt his power, the reflection of divine talent.

In spite of the day's heat, Alia felt suddenly cold. She felt the thin edge of her grip on the Imperium as a physical thing. She gripped the edge of her spy hole window as though to hold her power, thinking of its fragility. The balance of Landsraad, CHOAM, and Fremen arms held the core of power, while Spacing Guild and Bene Gesserit dealt silently in the shadows. The forbidden seepage of technological development which came from the edges of humankind's farthest migrations nibbled at the central power. Products permitted the Ixian and Tleilaxu factories could not relieve the pressure. And always in the wings there stood Farad'n of House Corrino, inheritor of Shaddam TV's titles and claims.

Without the Fremen, without House Atreides' monopoly on the geriatric spice, her grip would loosen. All the power would dissolve. She could feel it slipping from her right now. People heeded this Preacher. It would be dangerous to silence him; just as dangerous as it was to let him continue preaching such words as he'd shouted across her square today. She could see the first omens of her own defeat and the pattern of the problem stood out clearly in her mind. The Bene Gesserits had codified the problem:

"A large populace held in check by a small but powerful force is quite a common situation in our universe. And we know the major conditions wherein this large populace may turn upon its keepers -

"One: When they find a leader. This is the most volatile threat to the powerful; they must retain control of leaders.

"Two: When the populace recognizes its chains. Keep the populace blind and unquestioning.

"Three: When the populace perceives a hope of escape from bondage. They must never even believe that escape is possible!"

Alia shook her head, feeling her cheeks tremble with the force of movement. The signs were here in her populace. Every report she received from her spies throughout the Imperium reinforced her certain knowledge. Unceasing warfare of the Fremen Jihad left its mark everywhere. Wherever "the ecumenism of the sword" had touched, people retained the attitude of a subject population: defensive, concealing, evasive. All manifestations of authority - and this meant essentially religious authority - became subject to resentment. Oh, pilgrims still came in their thronging millions, and some among them were probably devout. But for the most part, pilgrimage had other motivations than devotion. Most often it was a canny surety for the future. It emphasized obedience and gained a real form of power which was easily translated into wealth. The Hajji who returned from Arrakis came home to new authority, new social status. The Hajji could make profitable economic decisions which the planet-bound of his homeworld dared not challenge.

Alia knew the popular riddle: "What do you see inside the empty purse brought home from Dune?" And the answer: "The eyes of Muad'Dib (fire diamonds)."

The traditional ways to counter growing unrest paraded themselves before Alia's awareness: people had to be taught that opposition was always punished and assistance to the ruler was always rewarded. Imperial forces must be shifted in random fashion. Major adjuncts to Imperial power had to be concealed. Every movement by which the Regency countered potential attack required delicate timing to keep the opposition off balance.

Have I lost my sense of timing? she wondered.

"What idle speculation is this?" a voice within her asked. She felt herself growing calmer. Yes, the Baron's plan was a good one. We eliminate the threat of the Lady Jessica and, at the same time, we discredit House Corrino. Yes.

The Preacher could be dealt with later. She understood his posture. The symbolism was clear. He was the ancient spirit of unbridled speculation, the spirit of heresy alive and functioning in her desert of orthodoxy. That was his strength. It didn't matter whether he was Paul... as long as that could be kept in doubt. But her Bene Gesserit knowledge told Alia that his strength would contain the key to his weakness.

The Preacher has a flaw which we will find. I will have him spied upon, watched every moment. And if the opportunity arises, he will be discredited.

Leto had come up in the night with Stilgar to the narrow ledge at the crest of the low rock outcropping which Sietch Tabr called The Attendant. Under the waning light of Second Moon, the ledge gave them a panoramic view - the Shield Wall with Mount Idaho to the north, the Great Flat to the south and rolling dunes eastward toward Habbanya Ridge. Winding dust, the aftermath of a storm, hid the southern horizon. Moonlight frosted the rim of the Shield Wall.

Stilgar had come against his will, joining the secretive venture finally because Leto aroused his curiosity. Why was it necessary to risk a sand crossing in the night? The lad had threatened to sneak away and make the journey alone if Stilgar refused. The way of it bothered him profoundly, though. Two such important targets alone in the night!

Leto squatted on the ledge facing south toward the flat. Occasionally he pounded his knee as though in frustration.

Stilgar waited. He was good at silent waiting, and stood two paces to one side of his charge, arms folded, his robe moving softly in the night breeze.

For Leto, the sand crossing represented a response to inner desperation, a need to seek a new alignment for his life in a silent conflict which Ghanima could no longer risk. He had maneuvered Stilgar into sharing the journey because there were things Stilgar had to know in preparation for the days ahead.
