“Why don’t they flee?” Perrin asked.

Hopper sent confusion.

“I’m going to them,” Perrin said, willing himself forward.

Nothing happened.

Perrin felt a stab of panic in his gut. What was wrong? He tried again, this time trying to send himself to the base of the dome.

It worked. He arrived in an eyeblink, that glasslike surface rising in a cliff face before him. It’s this dome, he thought. It’s blocking me. Suddenly, he understood the trapped feeling the wolves had sent. They couldn’t get away.

Was that the purpose of this dome, then? To trap wolves so that Slayer could kill them? Perrin growled, stepping up to the surface of the dome. He couldn’t pass in by imagining himself there, but perhaps he could get through by more mundane means. He raised a hand, then hesitated. He didn’t know what touching the surface would do.

The wolves sent images of a man in black and leather, with a harsh, lined face and a smile curling on his lips as he launched arrows. He smelled wrong, so wrong. He also smelled of dead wolves.

Perrin couldn’t leave them in there. No more than he could leave Master Gill and the others to the Whitecloaks. Furious at Slayer, he touched the surface of the dome.

His muscles suddenly lost strength. They felt like water, his legs unable to hold him up. He fell to the ground, hard. His foot was still touching the dome—passing through it. The dome appeared to have no substance.

His lungs no longer worked; inflating his chest was too difficult. Panicked, he imagined himself elsewhere, but it didn’t work. He was trapped, as surely as the wolves!

A gray-silver blur appeared next to him. Jaws grabbed his shoulder. As Hopper pulled him free of the violet dome, Perrin immediately felt his strength return. He gasped for breath.

Foolish cub, Hopper sent.

“You’d leave them?” Perrin said, voice ragged.

Not foolish to dig in the hole. Foolish for not waiting for me in case hornets came out. Hopper turned toward the dome. Help me if I fall. He padded forward, then touched his nose to the dome. Hopper stumbled, but righted himself and continued on slowly. On the other side, he collapsed, but his chest continued to move.

“How did you do it?” Perrin asked, rising.

I am me. Hopper as he saw himself—which was identical to who he was. Also scents of strength and stability.

The trick, it seemed, was to be in complete control of who you were. Like many things in the wolf dream, the strength of one’s mental image was more powerful than the substance of the world itself.

Come, Hopper sent. Be strong, pass through.

“I have a better idea,” Perrin said, standing up. He charged forward at full speed. He hit the violet dome and immediately went limp, but his momentum carried him to the other side, where he rolled to a stop. He groaned, shoulder hurt, arm scraped.

Foolish cub, Hopper sent. You must learn.
