SilverSide’s reaction to being seen by the Hunters was swift and powered by the Three Laws. The Third Law forced her to try to save herself. Second Law demanded that she follow the orders of humans, and though she was their leader, KeenEye’s commands to save the kin still carried weight; the First Law compelled her to do whatever she could to keep her people alive.

Which meant the prime consideration was that Central be destroyed.

SilverSide changed her shape as the Hunters turned to look up at her. She drew back the parafoil and thickened the body. Even as the Hunters raised their hands to fire their lasers, she became a streamlined, compact mass instead of a glider, and she dropped the last thirty feet like a massive stone, crashing heavily into the central column of Central. Laser beams crisscrossed the air where she had been; delicate circuitry smashed under her fall. SilverSide changed back to wolf form even as she rose from the wreckage of the core unit. She went to the wide panels surrounding the core and pushed with all the strength of her durable body. A panel toppled, striking the next in line-the array went down like a row of dominoes, sparking and crashing, the thunder of their destruction ringing in the cavernous room.

SilverSide fled the room, howling the ritual triumph of a victor even as she anticipated the Hunters’ lasers cutting her down. It didn’t matter to her. She’d done what she’d come to do.

But nothing happened; the Hunters had stopped.

Already confusion was spreading through the city-she could hear it, a thousand voices crying out in the VoidTongue that the OldMother had given her. WalkingStones were asking Central for instructions, but Central was not replying, would never reply. The alarm was spreading out through the various levels of this krajal-like society.

EMERGENCY! Central core memory damaged and off-line Command program inactive: secondary routines down.

Activate supervisory backups.

Behind her, SilverSide heard the Hunters stir. She raced into the corridor beyond Central’s room. There were no WalkingStones in sight there. She quickly altered herself once more to appear as one of the Hill of Stars’ Hunters, depending on the disguise to give her cover as she headed for the exit from the place. She listened to the continuing dialogue in her head.

City command given to Supervisor units Alpha, Beta, Gamma. The general announcement went out first over all frequencies, then three new voices boomed in her head. The direction finder in her skull indicated that all three were in widely scattered sections of the city.

ALPHA: Normal city subroutines accessed. City functions on-line and programming reinstated.

BETA: Alert situation! Central computer destroyed. Attacking unit in shape of local wolf-creatures is rogue robot. Repeat, attacking unit is robot not under control of City Supervisors.

GAMMA: Alert update. Witnessing units report sophisticated shape-changing abilities. Compass Tower Hunter-Seekers programming altered to compensate.

SilverSide increased her pace as she moved toward the exit. The corridor was crowded now, the WalkingStones returning to their routines. If the Hunters were aware that she could change shape, then her WalkingStone guise was not going to help her for very long. Someone would report her presence or discover the charade through some inadvertent response.

She knew that her victory had been short and bittersweet. Yes, she had destroyed Central. She had disrupted the city, if only momentarily. But the city had responded to the challenge all too well. If she interpreted the signals correctly, there were now three sub-Centrals, all in different places, and they knew her one advantage. If she were going to win this battle, she must move quickly, find all three of these Supervisors, and destroy them.

The next command from the trio of Supervisors dashed any hope SilverSide had at all.

ALPHA: All city units: access subroutine 3067.A.296. Immediately report any units not responding. Hold that unit at all costs until Hunter-Seekers arrive. Third Law precedence invoked - city survival involved: higher priority than individual survival.

All around her, moving WalkingStones came to an abrupt halt. An instant later, SilverSide did the same; it seemed safest.

She was wrong. A simultaneous alert was broadcast from the worker WalkingStones around her. ANOMALY! Hunter-Seeker unit in Compass Tower has stopped. In the same instant, all the workers in sight lunged for her.

SilverSide growled as she dropped back into her preferred wolf shape. She threw the nearest worker aside, the fragile body crumpling under her blow, and dashed through the opening it gave her. The alarm followed SilverSide as she darted from the building-she plowed through a worker who tried to block the entrance to the Hill of Stars and emerged into cool night.

She howled a lament.

Then she turned into the lumbering bird shape she had used once before, a black and sorrowing form.

Clumsily, her wings beat air, and she retreated from the city into the open sky. The false stars of the city below mocked her, and she knew there would be no hiding from the Hunters now.
