What would happen when all the grave sites were full?

Maybe Lord Hammer knew. But Hammer didn't have much to say.

We passed another circle about noon. It was dead.

The day was warmer, the sky clear. The ice began melting. We made good time. Lord Hammer seemed pleased.

I stared straight ahead, at Russ's back, all morning. If I looked at a tree I could hear it calling. The pull was terrifying.

Chenyth seized my arm. "Stop!"

I almost trampled Russ. "What's up?" Lord Hammer had stopped.

"I don't know."

Fetch was dancing around like a barefoot burglar on a floor covered with tacks. Lord Hammer and his steed might have been some parkland pigeon roost, so still were they. We shuffled round so we could see without leaving the safety of the trail.

We had come to a clearing. It was a quarter mile across. What looked like a mud-dauber's nest, the kind with just one hole, lay at the middle of the clearing. It was big. Like two hundred yards long, fifty feet wide, and thirty feet high. A sense of immense menace radiated from it.

"What is it?" we asked one another. Neither Lord Hammer nor Fetch answered us.

Lord Hammer slowly raised his left arm till it thrust straight out from his shoulder. He lifted his forearm vertically, turning the edge of a stiffened hand toward the structure. Then he raised his right arm, laying his forearm parallel with his eyeslits. Again he stiffened his hand, facing the structure with its edge.

"Let's go!" Fetch snapped. "Follow me." She started running.

We whipped the mules into a trot, ran. We weren't gentle with the balky ones.

We had to go right along the side of that thing. As we approached, I glanced back. Lord Hammer was coming, his mount pacing slowly. Hammer himself remained frozen in the position he had assumed. He was almost indiscernible inside a black nimbus.

His mask glowed like the sun. The face of an animal seemed to peep through the golden light.
