Topri moved to the room’s one door. There was a clattering bustle as everyone stood and the chairs were folded and stacked against the wall opposite the door. At a signal from Siona, Topri tapped three times on the door panel, waited for a two-count, then tapped four times.

The door opened and a tall man in a dark brown official singlet slipped into the room. He wore no mask, his face open for all of them to see—thin and imperious with a narrow mouth, a skinny blade of a nose, dark brown eyes deeply set under bushy brows. It was a face recognized by most of the room’s occupants.

“My friends,” Topri said, “I present Iyo Kobat, Ambassador from Ix.”

“Ex-Ambassador,” Kobat said. His voice was guttural and tightly controlled. He took a position with his back to the wall facing the masked people in the room. “I have this day received orders from our God Emperor to leave Arrakis in disgrace.”

“Why?”

Siona snapped the question at him without formality.

Kobat jerked his head around, a quick movement which fixed his gaze on her masked face. “There has been an attempt on the God Emperor’s life. He traced the weapon to me.”

Siona’s companions opened a space between her and the ex-Ambassador, clearly signalling that they deferred to her.

“Then why didn’t he kill you?” she demanded.

“I think he is telling me that I am not worth killing. There is also the fact that he uses me now to carry a message to Ix.”

“What message?” Siona moved through the cleared space to stop within two paces of Kobat. She recognized the sexual alertness in him as he studied her body.

“You are Moneo’s daughter,” he said.

Soundless tension exploded across the room. Why did he reveal that he recognized her? Who else did he recognize here? Kobat did not appear the fool. Why had he done this?

“Your body, your voice and your manner are well known here in Onn,” he said. “That mask is a foolishness.”

She ripped the mask from her head and smiled at him. “I agree. Now answer my question.”

Siona heard Nayla move up close on her left; two more aides chosen by Nayla came up beside her.

Siona saw the moment of realization come over Kobat—his death if he failed to satisfy her demands. His voice did not lose its tight control but he spoke slower, choosing his words more carefully.

“The God Emperor has told me that he knows about an agreement between Ix and the Guild. We are attempting to make a mechanical amplifier of… those Guild navigational talents which presently rely on melange.”

“In this room we call him the Worm,” Siona said. “What would your Ixian machine do?”

“You are aware that Guild Navigators require the spice before they can see the safe path to traverse?”

“You would replace the navigators with a machine?”

“It may be possible.”

“What message do you carry to your people concerning this machine?”
