Will I lose Gurney, too? Paul wondered. The way I lost Stilgar—losing a friend to gain a creature?
"They have no throwing weapons," Gurney said. "I've made sure of that myself." He glanced around the room, seeing Paul's preparations. "Feyd-Rautha Harkonnen is with them. Shall I cut him out?"
"Leave him."
"There're some Guild people, too, demanding special privileges, threatening an embargo against Arrakis. I told them I'd give you their message."
"Let them threaten."
"Paul!" Jessica hissed behind him. "He's talking about the Guild!"
"I'll pull their fangs presently," Paul said.
And he thought then about the Guild—the force that had specialized for so long that it had become a parasite, unable to exist independently of the life upon which it fed. They had never dared grasp the sword . . . and now they could not grasp it. They might have taken Arrakis when they realized the error of specializing on the melange awareness-spectrum narcotic for their navigators. They could have done this, lived their glorious day and died. Instead, they'd existed from moment to moment, hoping the seas in which they swam might produce a new host when the old one died.
The Guild navigators, gifted with limited prescience, had made the fatal decision: they'd chosen always the clear, safe course that leads ever downward into stagnation.
Let them look closely at their new host , Paul thought.
"There's also a Bene Gesserit Reverend Mother who says she's a friend of your mother," Gurney said.
"My mother has no Bene Gesserit friends."
Again, Gurney glanced around the Great Hall, then bent close to Paul's ear. "Thufir Hawat's with 'em, m'Lord. I had no chance to see him alone, but he used our old hand signs to say he's been working with the Harkonnens, thought you were dead. Says he's to be left among 'em."
"You left Thufir among those—"
"He wanted it . . . and I thought it best. If . . . there's something wrong, he's where we can control him. If not—we've an ear on the other side."
Paul thought then of prescient glimpses into the possibilities of this moment—and one time-line where Thufir carried a poisoned needle which the Emperor commanded he use against "this upstart Duke."
The entrance guards stepped aside, formed a short corridor of lances. There came a murmurous swish of garments, feet rasping the sand that had drifted into the Residency.
The Padishah Emperor Shaddam IV led his people into the hall. His burseg helmet had been lost and the red hair stood out in disarray. His uniform's left sleeve had been ripped along the inner seam. He was beltless and without weapons, but his presence moved with him like a force-shield bubble that kept his immediate area open.
A Fremen lance dropped across his path, stopped him where Paul had ordered. The others bunched up behind, a montage of color, of shuffling and of staring faces.
Paul swept his gaze across the group, saw women who hid signs of weeping, saw the lackeys who had come to enjoy grandstand seats at a Sardaukar victory and now stood choked to silence by defeat. Paul saw the bird-bright eyes of the Reverend Mother Gaius Helen Mohiam glaring beneath her black hood, and beside her the narrow furtiveness of Feyd-Rautha Harkonnen.
There's a face time betrayed to me , Paul thought.
He looked beyond Feyd-Rautha then, attracted by a movement, seeing there a narrow, weaselish face he'd never before encountered—not in time or out of it. It was a face he felt he should know and the feeling carried with it a marker of fear.
Why should I fear that man? he wondered.
He leaned toward his mother, whispered: "That man to the left of the Reverend Mother, the evil-looking one—who is that?"
Jessica looked, recognizing the face from her Duke's dossiers. "Count Fenring," she said. "The one who was here immediately before us. A genetic-eunuch . . . and a killer."
The Emperor's errand boy , Paul thought. And the thought was a shock crashing across his consciousness because he had seen the Emperor in uncounted associations spread through the possible futures—but never once had Count Fenring appeared within those prescient visions.
It occurred to Paul then that he had seen his own dead body along countless reaches of the time web, but never once had he seen his moment of death.
