God Emperor of Dune

With his own hands, in the early days of his ascendancy, Leto has used an Ixian machine to dig a secret tunnel under the Sareer to his tower, doing all of the work himself. In those days, a few wild sandworms still roamed the desert. He had lined his tunnel with massive walls of fused silica and had imbedded countless bubbles of worm-repelling water in the outer layers. The tunnel anticipated his maximum growth and the requirements of a Royal Cart which, at that time, had been only a figment of his visions, In the early predawn hours of the day assigned to Siona, Leto descended to the crypt and gave orders to his guard that he was not to be disturbed by anyone. His cart sped him down one of the crypt's dark spokes where he opened a hidden portal, emerging in less than an hour at the Little Citadel.

One of his delights was to go out alone onto the sand. No cart. Only his pre-worm body to carry him. The sand felt luxuriously sensuous against him. The heat of his passage through the dunes in the day's first light sent up a wake of steam which required him to keep moving. He brought himself to a stop only when he found a relatively dry pocket about five kilometers out. He lay there at the center of an uncomfortable dampness from the trace-dew, his body just outside the long shadow of the tower which stretched eastward from him across the dunes.

From a distance, the three thousand meters of the tower could be seen as an impossible needle stabbing the sky. Only the inspired blend of Leto's commands and Ixian imagination made the structure conceivable. One hundred and fifty meters in diameter, the tower sat on a foundation which plunged as deeply under the sand as it climbed above. The magic of plasteel and superlight alloys kept it supple in the wind and resistant to sandblast abrasions.

Leto enjoyed the place so much that he rationed his visits, making up a long list of personal rules which had to be met. The rules added up to "Great Necessity."

For a few moments while he lay there, he could shed the loads of the Golden Path. Moneo, good and reliable Moneo, would see that Siona arrived promptly, just at nightfall. Leto had a full day in which to relax and think, to play and pretend that he possessed no cares, to drink up the raw sustenance of the earth in a feeding frenzy which he could never indulge in at Onn or at the Citadel. In those places, he was required to confine himself to furtive burrowings through narrow passages where only prescient caution kept him from encountering waterpockets. Here, though, he could race through the sand and across it, feed and grow strong.

Sand crunched beneath him as he rolled, flexing his body in pure animal enjoyment. He could feel his worm-self being restored, an electric sensation which sent messages of health all through him.

The sun was well above the horizon now, painting a golden line up the side of the tower. There was the smell of bitter dust in the air and an odor of distant spiny plants which had responded to the morning's trace-dew. Gently at first, then more rapidly, he moved out in a wide circle around the tower, thinking about Siona as he went.

There could be no more delays. She had to be tested. Moneo knew this as well as Leto did.

Just that morning, Moneo had said: "Lord, there is terrible violence in her."

"She has the beginnings of adrenalin addiction," Leto had said. "It's cold-turkey time."

"Cold what, Lord?"

"It's an ancient expression. It means she must be subjected to a complete withdrawal. She must go through a necessity shock."

"Oh... I see."

For once, Leto realized, Moneo did see. Moneo had gone through his own cold-turkey time.

"The young generally are incapable of making hard decisions unless those decisions are associated with immediate violence and the consequent sharp flow of adrenalin," Leto had explained.

Moneo had held himself in reflexive silence, remembering, then: "It is a great peril."

"That's the violence you see in Siona. Even old people can cling to it, but the young wallow in it."

As he circled his tower in the growing light of the day, enjoying the feel of the sand even more as it dried, Leto thought about the conversation. He slowed his passage over the sand. A wind from behind him carried the vented oxygen and a burnt flint smell over his human nostrils. He inhaled deeply, lifting $ his magnified awareness to a new level.

This preliminary day contained a multiple purpose. He thought of the coming encounter much as an ancient bullfighter had thought about the first examination of a horned adversary. Siona possessed her own version of horns, although Moneo would make certain that she brought no physical weapons to this encounter. Leto had to be sure, though, that he knew Siona's every strength and every weakness. And he would have to create special susceptibilities in her wherever possible. She had to be prepared for the test, her psychic muscles blunted by well-planted barbs.
