One of the D-wolves, a large female, moved out on Ulot's left flank. She swerved inward and leaped across his path. Giant fangs ripped Ulot's shoulder and staggered him but he did not fall. The pungency of blood was added to the forest smells. A smaller male caught his right hip and at last Ulot fell, screaming. The pack pounced and his screams were cut off in abrupt finality.

Not stopping to feed, the D-wolves again took up the chase. Their noses probed the forest floor and the vagrant eddies in the air, scenting the warm tracery of two more running humans.

The next runner in the line was named Kwuteg, an old and honorable name on Arrakis, a name from the Dune times. An ancestor had served Sietch Tabr as Master of the Deathstills, but that was more than three thousand years lost in a past which many no longer believed. Kwuteg ran with the long strides of a tall and slender body which seemed perfectly fitted to such exertion. Long black hair streamed back from his aquiline features. As with his companions, he wore a black running suit of tightly knitted cotton. It revealed the workings of his buttocks and stringy thighs, the deep and steady rhythm of his breathing. Only his pace, which was markedly slow for Kwuteg, betrayed the fact that he had injured his right knee coming down from the man-made precipices which girdled the God Emperor's Citadel fortress in the Sareer.

Kwuteg heard Ulot's screams, the abrupt and potent silence, then the renewed chase-yelps of the D-wolves. He tried not to let his mind create the image of another friend being slain by Leto's monster guardians but imagination worked its sorcery on him. Kwuteg thought a curse against the tyrant but wasted no breath to voice it. There remained a chance that he could reach the sanctuary of the Idaho River. Kwuteg knew what his friends thought about him-even Siona. He had always been known as a conservative. Even as a child he had saved his energy until it counted most, parceling out his reserves like a miser.
