He caught glimpses of Hopper bounding ahead. His prey vanished. Young Bull didn’t break pace, charging through that spot and catching the scent of Hopper’s destination. Young Bull shifted onto an open plain with no trees and an unfamiliar scrub patching the ground. His prey was a series of streaking blurs in the distance. Young Bull followed, each bound carrying him hundreds of paces.

Within seconds, they approached an enormous plateau. His prey ran directly up the side of the stone shelf. Young Bull followed, ignoring what was “right.” He ran with the ground far below at his back, nose toward that boiling sea of black clouds. He leaped over clefts in the rock, ricocheting between two sides of a rift, cresting the top of the plateau.

Hopper attacked. Young Bull was ready. He rolled, coming up on all fours as his prey leaped over his head, passed over the cliff’s edge, but then vanished in a flash and was back standing on the lip of the cliff.

Young Bull became Perrin holding a hammer made of soft wood. Such things were possible in the wolf dream; if the hammer hit, it would not harm.

Perrin swung, the air cracking with the sudden speed of his motion. But Hopper was equally fast, dodging out of the way. He rolled, then leaped at Perrin’s back, fangs glistening. Perrin growled and shifted so that he was standing a few feet from where he had been. Hopper’s jaws snapped open air, and Perrin swung his hammer again.

Hopper was suddenly shrouded in a deep mist. Perrin’s hammer slammed down through it, hitting the ground. It bounced off. He cursed, spinning. In the fog, he couldn’t see, couldn’t catch Hopper’s scent.

A shadow moved in the mist and Perrin lunged, but it was only a pattern in the air. He spun and found shadows moving all around him. The shapes of wolves, men, and other creatures he couldn’t see.

Make the world yours, Young Bull, Hopper sent.

Perrin focused, thinking of dry air. Of the musty scent of dust. That was what the air should be like, in an arid landscape like this.

No. It wasn’t what the air should be like. It was how the air was! His mind, his will, his feelings slammed against something else. He pushed through.

The mists vanished, evaporating in the heat. Hopper sat on his haunches a short distance away. Good, the wolf sent. You learn. He glanced sideways, looking toward the north, seeming distracted by something. Then he was gone.

Perrin caught his scent and followed to the Jehannah Road. Hopper dashed along outside the strange violet dome. They jumped back to this place frequently to see if the dome ever vanished. So far, it had not.

Perrin continued the chase. Was the dome meant to trap wolves inside? But if that was the case, why had Slayer not sprung his trap at Dragonmount, where so many wolves had for some reason gathered?

Perhaps the dome had another purpose. Perrin memorized a few notable rock formations along the perimeter of the dome, then followed Hopper to a low shelf of rock. The wolf leaped from it, vanishing in midair, and Perrin followed.
