Presently the light winked out. The hooded figure moved with a betraying swish of fabric, took up a station at one side of the arched doorway. Anyone aware of the routine here in Sietch Tabr would have suspected at once that this must be Stilgar, Naib of the Sietch, guardian of the orphaned twins who would one day take up the mantle of their father, Paul Muad'Dib. Stilgar often made night inspections of the twins' quarters, always going first to the chamber where Ghanima slept and ending here in the adjoining room, where he could reassure himself that Leto was not threatened.

I'm an old fool, Stilgar thought.

He fingered the cold surface of the light projector before restoring it to the loop in his belt sash. The projector irritated him even while he depended upon it. The thing was a subtle instrument of the Imperium, a device to detect the presence of large living bodies. It had shown only the sleeping children in the royal bedchambers.

Stilgar knew his thoughts and emotions were like the light. He could not still a restless inner projection. Some greater power controlled that movement. It projected him into this moment where he sensed the accumulated peril. Here lay the magnet for dreams of grandeur throughout the known universe. Here lay temporal riches, secular authority and that most powerful of all mystic talismans: the divine authenticity of Muad'Dib's religious bequest. In these twins - Leto and his sister Ghanima - an awesome power focused. While they lived, Muad'Dib, though dead, lived in them.

These were not merely nine-year-old children; they were a natural force, objects of veneration and fear. They were the children of Paul Atreides, who had become Muad'Dib, the Mahdi of all the Fremen. Muad'Dib had ignited an explosion of humanity; Fremen had spread from this planet in a jihad, carrying their fervor across the human universe in a wave of religious government whose scope and ubiquitous authority had left its mark on every planet.
