SilverSide brought the pack to a ragged halt at a ridge looking down into the shallow bowl of a valley perhaps a kilometer across at its widest point. She sat in the shadows of the last few trees; LifeCrier and KeenEye came forward and sat on their haunches to either side of the new leader. SmallFace was high in the sky; LargeFace had yet to rise. The stars-the VoidEyes, as LifeCrier called them-stared down at the city and marveled.

SilverSide felt some of that awe herself. The Hill of Stars, set like a glistening diamond in the center of the valley and rising well above the level of the surrounding hills, was a fantastic pattern of glowing lights. The slender pyramidal structure mocked the glory of the night sky.

Nor was the Hill of Stars all. Other buildings spread out around it in geometric splendor, a procession of hard, crystalline shapes filling the valley and spilling out its open end, all linked by ribbons of walkways.

And everywhere, everywhere. there were WalkingStones: all different sizes, all different builds, all different colors. They bustled along the walkways, gazed from the windows of the buildings, slid busily between the flanks of the city. There were thousands of them.

They moved in an eerie, almost mystical silence-at least to the kin. But SilverSide could hear the deafening roar of the city’s voices inside her head. An eternal chatter of orders and instructions came from the central computer; reports were constantly being funneled back to that source. And she understood the words, for they spoke as the Hunter spoke, in that language SilverSide guessed must be that of the Void where the gods lived. It was more proof that the OldMother was being opposed.

“They began with just the Hill of Stars,” KeenEye whispered to SilverSide. She panted at the remembrance, and her long, furless tail lashed from side to side. “They’ve worked like the krajal since then.”

SilverSide had seen the industrious insects called the krajal toiling ceaselessly through the undergrowth of the forest, building their mud colonies on the sides of trees. KeenEye pointed a long finger at the periphery of the city, her lips drawn back from canines in a snarl.

“See how they tear down the trees and destroy the land?” she rasped. “All this valley was forest before the WalkingStones came. They destroy everything to put up their stone caves. And the light-it’s as if the sun were resting down there for the night. The WalkingStones don’t care about kin or any of the living creatures. They don’t care that our prey animals have fled. They don’t care that their stone caves stretch out and out and out. Long before they reach PackHome, we will have left. We will have starved, or we will have been killed.”

“Do these other WalkingStones hurt the kin like the one we killed?” SilverSide asked. “There must be different species of WalkingStones down there.”

“We don’t know,” KeenEye answered. “The others have never bothered us. They stay within the stones. Only the Hunters ever come outside.”

“That also makes them like the krajal,” LifeCrier added. “Only the blue krajali get food, only the yellow-speckled krajali build the tree-homes; only the red krajali defend the homes against the LongTongues. They each have a separate task to do, and they each are shaped a little differently. Maybe it’s the same with these WalkingStones.”

SilverSide’s optics focused more closely on the hive of activity. What LifeCrier had said sounded like an accurate enough metaphor. The view of the city bore that out. Certainly the WalkingStones seemed specialized in appearance. And though the WalkingStones were obviously constructed things, their hard, unyielding bodies were like the chitinous shells of insects.

Maybe the enemy of the OldMother had fashioned the WalkingStones after insects. They had the same outward silence, and their chattering inside her head to the unseen Central seemed like the clickings of insects. Like the insect, they labored with seemingly untiring energy; like the krajal they built their own colony home rather than take refuge in what nature afforded. And this Central, perhaps that was the queen, directing all activities of the hive.

The intricacy and sophistication of the city echoed in SilverSide. It awoke memories of her initial urges: find sentient life. Find humans. She’d made the decision on what was human, but the intelligence behind the WalkingStones…

…but that was the province of the gods, or so LifeCrier’s tales had indicated. A god had sent the WalkingStones as a god had sent SilverSide herself. It felt right to admire the genius that had created the WalkingStones, a resonance of the Third Law commands that had shaped her first hours. But admiration didn’t mean that the WalkingStones weren’t enemies. SilverSide had made her choice; the OldMother had sent her to the kin.

But still…The kin were human, yes, but SilverSide yearned for something more.

“Sometimes the krajal infest a place, too,” LifeCrier was saying. “The queen breeds and breeds until the trees drip with the shiny bodies. They drop on the prey animals and bite, driving them mad until they flee. They can kill a youngling-a slow and horrible death.”

LifeCrier closed his eyes, as if remembering. “The last time that happened, two LifeCriers ago, HalfTongue was the leader. During a storm, lightning struck a tree. HalfTongue noticed that the flames killed the krajal and that they fled. She took a branch from the tree and set a blue krajali on fire. The nearby reds came to defend it, leaving an opening. So HalfTongue and the others took several burning brands and began using them to drive the krajal away until they could reach the queen and kill it. Once the queen was dead, the krajal behaved like crazy things and were easy to kill.”

“WalkingStones won’t burn. You can’t burn a rock.” KeenEye’s comment was laced with her old scorn. If she was resigned to a secondary place in the pack behind SilverSide, she was also not going to submit to any of the other kin. “The WalkingStones would laugh at a burning stick.”

SilverSide nodded in agreement, scenting KeenEye’s irritation with LifeCrier’s tales. “Still, there is a hint in LifeCrier’s story. I must find out more about these WalkingStones. KeenEye, you will lead the pack in my absence. I will go down into the city. I need to discover if these other types of WalkingStones are more vulnerable than the Hunters. If what I suspect is true, then the Hunters will come after I attack. You must watch-see what they do, see how many they send and how quickly. Then go back to PackHome quickly. I will return by another route after I have made certain that no Hunters follow me.”

“If you’re not killed right away,” KeenEye said. Her pale eyes were noncommital and SilverSide could not tell if the prospect pleased or disturbed her. “If you’re right about these other WalkingStones.”

“If anything happens to me, you become leader again,” SilverSide answered. Yes, she scented satisfaction in KeenEye with that, and she continued. “But it won’t. I don’t intend to fight the Hunters. I only need to see how they react so we can plan. You can’t hear them, but I can. The WalkingStones speak; they communicate as do the kin. I can use their language against them. I might be able to deceive them.”

“GrayMane knew the language of the OldMother,” LifeCrier said. “You see, KeenEye, it is as I said. “

KeenEye grimaced, but she said nothing.

“Watch me for the time it would take to skin a deer,” SilverSide told the group. “Remember what you see, every detail. It is very important. Then leave. Go directly back to PackHome.” SilverSide used HuntTongue to accentuate the command.

KeenEye grimaced again, but she nodded. “As you wish.“

SilverSide gave a soft bark of satisfaction. She looked at the pack, who watched the trio expectantly. The sight of the kin nudged a First Law circuit. “Keep them safe, KeenEye,” SilverSide said. “Take them back as swiftly as they can go-the Hunters may come after you if I can’t lead them away. “

“I will do as SilverSide wishes,” KeenEye answered in proud HuntTongue. “She does not have to worry.”

There was nothing more to say. SilverSide glanced around the edge of the forest, making sure that no Hunters were lurking nearby. Swiftly, she dropped onto four legs and moved out into the wash of moonlight. She was a swift, glinting presence sliding into the shadows of the nearest buildings. SilverSide moved in among them several strides, then hunched down, belly to cool stone behind one of the structures.

She listened. The WalkingStones chattered to Central endlessly. Reports went in, orders went out. The WalkingStones were concentrated more toward the Hill of Stars where SilverSide suspected Central hid, but they occasionally moved through this area. She waited, patient.

When she heard the sound of a WalkingStone’s tread, she allowed her body to deform slightly, extending an eyestalk around the comer of the building. The approaching WalkingStone was a spindly, gangly thing with arms tipped by mechanical claws rather than fingered hands. It was alone. SilverSide retracted the eyestalk, gathered herself; when the WalkingStone passed the side of the building, she leaped with a BeastTalk growl.

The WalkingStone’s arms came up too late-SilverSide hit it, her jaws clamping around the thin, long neck and her powerful muscles shaking the thing from side to side. She was careful to hold her own great strength back and use no more power than any of the kin possessed.

That strength was enough, as she had suspected. These WalkingStones were far less durable than the Hunters. A support cracked; internal wiring harnesses tore. Just before the main trunk to the brain was severed and the WalkingStone went still under SilverSide’s great bulk, she heard it call out to the distant Central.

Under attack. Damaged… .

SilverSide let the thing slump to the ground. Yes, as I thought. The Hunters were designed to be the city’s protection; the workers were strong but not overwhelming for a creature as powerful as the wolf-creatures. The worker WalkingStones, at least, were vulnerable.

And this also revealed another weakness. Not much of one, but it was all SilverSide had.

The voices in her head had gone silent. Replacing the chatter was an amplified voice, loud and commanding, resonating on all the frequencies. Central. My enemy.
