IN THE warm season when the satellite weather controllers were forced to contend with winds across the great seas, evening often saw rainfall at the edges of the Sareer. Moneo, coming in from one of his periodic inspections of the Citadel's perimeter, was caught in a sudden shower. Night fell before he reached shelter. A Fish Speaker guard helped him out of his damp cloak at the south portal. She was a heavyset, blocky woman with a square face, a type Leto favored for his guardians.

"Those damned weather controllers should be made to shape up," she said as she handed him his damp cloak.

Moneo gave her a curt nod before beginning the climb to his quarters. All of the Fish Speaker guards knew the God Emperor's aversion to moisture, but none of them made Moneo's distinction.

It is the Worm who hates water, Moneo thought. Shai-Hulud hungers for Dune.

In his quarters, Moneo dried himself and changed to dry clothing before descending to the crypt. There was no point in inviting the Worm's antagonism. Uninterrupted conversation with Leto was required now, plain talk about the impending peregrination to the Festival City of Onn.

Leaning against a wall of the descending lift, Moneo closed his eyes. Immediately, fatigue swept over him. He knew he had not slept enough in days and there was no let up in sight. He envied Leto's apparent freedom from the need for sleep. A few hours of semi repose a month appeared to be sufficient for the God Emperor.

The smell of the crypt and the stopping of the lift jarred Moneo from his catnap. He opened his eyes and looked out at the God Emperor on his cart in the center of the great chamber. Moneo composed himself and strode out for the familiar long walk into the terrible presence. As expected, Leto appeared alert. That, at least, was a good sign.

Leto had heard the lift approaching and saw Moneo awaken. The man looked tired and that was understandable. The peregrination to Onn was at hand with all of the tiresome business of off-planet visitors, the ritual with the Fish Speakers, the new ambassadors, the changing of the Imperial Guard, the retirements and the appointments, and now a new Duncan Idaho ghola to fit into the smooth working of the Imperial apparatus. Moneo was occupied with mounting details and he was beginning to show his age.

Let me see, Leto thought. Moneo will be one hundred and eighteen years old in the week after our return from Onn.

The man could live many times that long if he would take the spice, but he refused. Leto had no doubt of the reason. Moneo had entered that peculiar human state where he longed for death. He lingered now only to see Siona installed in the

Royal Service, the next director of the Imperial Society of Fish Speakers.

My houris, as Malky used to call them.

And Moneo knew it was Leto's intention to breed Siona with a Duncan. It was time.

Moneo stopped two paces from the cart and looked up at Leto. Something in his eyes reminded Leto of the look on the face of a pagan priest in the Terran times, a crafty supplication at the familiar shrine.

"Lord, you have spent many hours observing the new Duncan," Moneo said. "Have the Tleilaxu tampered with his cells or his psyche?"

"He is untainted."

A deep sigh shook Moneo. There was no pleasure in it.

"You object to his use as a stud?" Leto asked.

"I find it peculiar to think of him as both an ancestor and the father of my descendants."

"But he gives me access to a first-generation cross between an older human form and the current products of my breeding program. Siona is twenty-one generations removed from such a cross."

"I fail to see the purpose. The Duncans are slower and less alert than anyone in your Guard."

"I am not looking for good segregant offspring, Moneo. Did you think me unaware of the progression geometrics dictated by the laws which govern my breeding program?"

"I have seen your stock book, Lord."

"Then you know that I keep track of the recessives and weed them out. The key genetic dominants are my concern."

"And the mutations, Lord?" There was a sly note in Moneo's voice which caused Leto to study the man intently.

"We will not discuss that subject, Moneo."

Leto watched Moneo pull back into his cautious shell.

How extremely sensitive he is to my moods, Leto thought. I do believe he has some of my abilities there, although they operate at an unconscious level. His question suggests that he may even suspect what we have achieved in Siona.

Testing this, Leto said, "It is clear to me that you do not yet understand what I hope to achieve in my breeding program."

Moneo brightened. "My Lord knows I try to fathom the rules of it."

"Laws tend to be temporary over the long haul, Moneo. There is no such thing as rule-governed creativity."

"But Lord, you yourself speak of laws which govern your breeding program."

"What have I just said to you, Moneo? Trying to find rules for creation is like trying to separate mind from body."

"But something is evolving, Lord. I know it in myself!"

He knows it in himself! Dear Moneo. He is so close.

"Why do you always seek after absolutely derivative translations, Moneo?"

"I have heard you speak of transformational evolution, Lord. That is the label on your stock book. But what of surprise..."

"Moneo! Rules change with each surprise."

"Lord, have you no improvement of the human stock in mind?"

Leto glared down at him, thinking: If I use the key word now, will he understand? Perhaps...

"I am a predator, Moneo."

"Pred..." Moneo broke off and shook his head. He knew the meaning of the word, he thought, but the word itself shocked him. Was the God Emperor joking?

"Predator, Lord?"

"The predator improves the stock."

"How can this be, Lord? You do not hate us."

"You disappoint me, Moneo. The predator does not hate its prey."

"Predators kill, Lord."

"I kill, but I do not hate. Prey assuages hunger. Prey is good."

Moneo peered up at Leto's face in its gray cowl.

Have I missed the approach of the Worm? Moneo wondered.

Fearfully, Moneo looked for the signs. There were no tremors in the giant body, no glazing of the eyes, no twisting of the useless flippers.

"For what do you hunger, Lord?" Moneo ventured.

"For a humankind which can make truly long-term decisions. Do you know the key to that ability, Moneo?"

"You have said it many times, Lord. It is the ability to change your mind."

"Change, yes. And do you know what I mean by longterm?"

"For you, it must be measured in millennia, Lord."

"Moneo, even my thousands of years are but a puny blip against Infinity."

"But your perspective must be different from mine, Lord." "In the view of Infinity, any defined long-term is shortterm."
