Presently the royal pair met in the antechamber, noting the sudden stillness of the attendants. Leto, it was observed, wore a black-edged tan cape over his stillsuit's grey slickness. His sister wore a green cape. The neck of each cape was held by a clasp in the form of an Atreides hawk - gold with red jewels for eyes.

Seeing this finery, Harah, who was one of Stilgar's wives, said: "I see you have dressed to honor your grandmother." Leto picked up his breakfast bowl before looking at Harah's dark and wind-creased face. He shook his head. Then: "How do you know it's not ourselves we honor?"

Harah met his taunting stare without flinching, said: "My eyes are just as blue as yours!"

Ghanima laughed aloud. Harah was always an adept at the Fremen challenge-game. In one sentence, she had said: "Don't taunt me, boy. You may be royalty, but we both bear the stigma of melange-addiction - eyes without whites. What Fremen needs more finery or more honor than that?"

Leto smiled, shook his head ruefully. "Harah, my love, if you were but younger and not already Stilgar's, I'd make you my own."

Harah accepted the small victory easily, signaling the other attendants to continue preparing the chambers for this day's important activities. "Eat your breakfasts," she said. "You'll need the energy today."

"Then you agree that we're not too fine for our grandmother?" Ghanima asked, speaking around a mouthful of gruel.

"Don't fear her, Ghani," Harah said.

Leto gulped a mouthful of gruel, sent a probing stare at Harah. The woman was infernally folk-wise, seeing through the game of finery so quickly. "Will she believe we fear her?" Leto asked.

"Like as not," Harah said. "She was our Reverend Mother, remember. I know her ways."

"How was Alia dressed?" Ghanima asked.

"I've not seen her." Harah spoke shortly, turning away.

Leto and Ghanima exchanged a look, of shared secrets, bent quickly to their breakfast. Presently they went out into the great central passage.

Ghanima spoke in one of the ancient languages they shared in genetic memory: "So today we have a grandmother."

"It bothers Alia greatly," Leto said.

"Who likes to give up such authority?" Ghanima asked.

Leto laughed softly, an oddly adult sound from flesh so young. "It's more than that."

"Will her mother's eyes observe what we have observed?"

"And why not?" Leto asked.

"Yes... That could be what Alia fears."

"Who knows Abomination better than Abomination?" Leto asked.

"We could be wrong, you know," Ghanima said.

"But we're not." And he quoted from the Bene Gesserit Azhar Book: "It is with reason and terrible experience that we call the pre-born Abomination. For who knows what lost and damned persona out of our evil past may take over the living flesh?"

"I know the history of it," Ghanima said. "But if that's true, why don't we suffer from this inner assault?"

"Perhaps our parents stand guard within us," Leto said.

"Then why not guardians for Alia as well?"

"I don't know. It could be because one of her parents remains among the living. It could be simply that we are still young and strong. Perhaps when we're older and more cynical..."

"We must take great care with this grandmother," Ghanima said.

"And not discuss this Preacher who wanders our planet speaking heresy?"

"You don't really think he's our father!"

"I make no judgment on it, but Alia fears him."

Ghanima shook her head sharply. "I don't believe this Abomination nonsense!"

"You've just as many memories as I have," Leto said. "You can believe what you want to believe."

"You think it's because we haven't dared the spice trance and Alia has," Ghanima said.

"That's exactly what I think."

They fell silent, moving out into the flow of people in the central passage. It was cool in Sietch Tabr, but the stillsuits were warm and the twins kept their condenser hoods thrown back from their red hair. Their faces betrayed the stamp of shared genes: generous mouths, widely set eyes of spice addict blue-on-blue.

Leto was first to note the approach of their Aunt Alia.

"Here she comes now," he said, shifting to Atreides battle language as a warning.

Ghanima nodded to her aunt as Alia stopped in front of them, said: "A spoil of war greets her illustrious relative." Using the same Chakobsa language, Ghanima emphasized the meaning of her own name - Spoil of War.

"You see, Beloved Aunt," Leto said, "we prepare ourselves for today's encounter with your mother."

Alia, the one person in the teeming royal household who harbored not the faintest surprise at adult behavior from these children, glared from one to the other. Then: "Hold your tongues, both of you!"

Alia's bronze hair was pulled back into two golden water rings. Her oval face held a frown, the wide mouth with its downturned hint of self-indulgence was held in a tight line. Worry wrinkles fanned the corners of her blue-on-blue eyes.

"I've warned both of you how to behave today," Alia said. "You know the reasons as well as I."

"We know your reasons, but you may not know ours," Ghanima said.

"Ghani!" Alia growled.

Leto glared at his aunt, said: "Today of all days, we will not pretend to be simpering infants!"

"No one wants you to simper," Alia said. "But we think it unwise for you to provoke dangerous thoughts in my mother. Irulan agrees with me. Who knows what role the Lady Jessica will choose? She is, after all, Bene Gesserit."

Leto shook his head, wondering: Why does Alia not see what we suspect? Is she too far gone? And he made special note of the subtle gene-markers on Alia's face which betrayed the presence of her maternal grandfather. The Baron Vladimir Harkonnen had not been a pleasant person. At this observation, Leto felt the vague stirrings of his own disquiet, thinking: My own ancestor, too.

He said: "The Lady Jessica was trained to rule."

Ghanima nodded. "Why does she choose this time to come back?"

Alia scowled. Then: "Is it possible she merely wants to see her grandchildren?"

Ghanima thought: That's what you hope, my dear aunt. But it's damned well not likely.

"She cannot rule here," Alia said. "She has Caladan. That should be enough."

Ghanima spoke placatingly: "When our father went into the desert to die, he left you as Regent. He..."

"Have you any complaint?" Alia demanded.

"It was a reasonable choice," Leto said, following his sister's lead. "You were the one person who knew what it was like to be born as we were born."

"It's rumored that my mother has returned to the Sisterhood," Alia said, "and you both knew what the Bene Gesserit think about..."

"Abomination," Leto said.

"Yes!" Alia bit the word off.

"Once a witch, always a witch - so it's said," Ghanima said.

Sister, you play a dangerous game, Leto thought, but he followed her lead, saying: "Our grandmother was a woman of greater simplicity than others of her kind. You share her memories, Alia; surely you must know what to expect."

"Simplicity!" Alia said, shaking her head, looking around her at the thronged passage, then back to the twins. "If my mother were less complex, neither of you would be here - nor I. I would have been her firstborn and none of this..." A shrug, half shudder, moved her shoulders. "I warn you two, be very careful what you do today." Alia looked up. "Here comes my guard."

"And you still don't think it safe for us to accompany you to the spaceport?" Leto asked.

"Wait here," Alia said. "I'll bring her back."

Leto exchanged a look with his sister, said: "You've told us many times that the memories we hold from those who've passed before us lack a certain usefulness until we've experienced enough with our own flesh to make them reality. My sister and I believe this. We anticipate dangerous changes with the arrival of our grandmother."
