Dune

And what he saw was a time nexus within this cave, a boiling of possibilities focused here, wherein the most minute action—the wink of an eye, a careless word, a misplaced grain of sand—moved a gigantic lever across the known universe. He saw violence with the outcome subject to so many variables that his slightest movement created vast shiftings in the pattern.

The vision made him want to freeze into immobility, but this, too, was action with its consequences.

The countless consequences—lines fanned out from this cave, and along most of these consequence-lines he saw his own dead body with blood flowing from a gaping knife wound.

My father, the Padishah Emperor, was 72 yet looked no more than 35 the year he encompassed the death of Duke Leto and gave Arrakis back to the Harkonnens. He seldom appeared in public wearing other than a Sardaukar uniform and a Burseg's black helmet with the imperial lion in gold upon its crest. The uniform was an open reminder of where his power lay. He was not always that blatant, though. When he wanted, he could radiate charm and sincerity, but I often wonder in these later days if anything about him was as it seemed. I think now he was a man fighting constantly to escape the bars of an invisible cage. You must remember that he was an emperor, father-head of a dynasty that reached back into the dimmest history. But we denied him a legal son. Was this not the most terrible defeat a ruler ever suffered? My mother obeyed her Sister Superiors where the Lady Jessica disobeyed. Which of them was the stronger? History already has answered.

Jessica awakened in cave darkness, sensing the stir of Fremen around her, smelling the acrid stillsuit odor. Her inner timesense told her it would soon be night outside, but the cave remained in blackness, shielded from the desert by the plastic hoods that trapped their body moisture within this space.

She realized that she had permitted herself the utterly relaxing sleep of great fatigue, and this suggested something of her own unconscious assessment on personal security within Stilgar's troop. She turned in the hammock that had been fashioned of her robe, slipped her feet to the rock floor and into her desert boots.

I must remember to fasten the boots slip-fashion to help my stillsuit's pumping action , she thought. There are so many things to remember .

She could still taste their morning meal—the morsel of bird flesh and grain bound within a leaf with spice honey—and it came to her that the use of time was turned around here: night was the day of activity and day was the time of rest.

Night conceals; night is safest .

She unhooked her robe from its hammock pegs in a rock alcove, fumbled with the fabric in the dark until she found the top, slipped into it.

How to get a message out to the Bene Gesserit? she wondered. They would have to be told of the two strays in Arrakeen sanctuary.

Glowglobes came alight farther into the cave. She saw people moving there, Paul among them already dressed and with his hood thrown back to reveal the aquiline Atreides profile.

He had acted so strangely before they retired, she thought. Withdrawn . He was like one come back from the dead, not yet fully aware of his return, his eyes half shut and glassy with the inward stare. It made her think of his warning about the spice-impregnated diet: addictive .

Are there side effects? she wondered. He said it had something to do with his prescient faculty, but he has been strangely silent about what he sees .

Stilgar came from shadows to her right, crossed to the group beneath the glowglobes. She marked how he fingered his beard and the watchful, cat-stalking look of him.
