The monster wheeled about again, and again it rushed down the sky at him, even lower than before; he leaned sideways in the saddle, ducking out of its path, and struck upward again. The point of his sword bounced and scratched along the creature's belly, then rang metallically from a hind leg and was knocked aside. There was still no sign that the dragon had felt a thing.

If it came in any lower on its next pass, Garth knew, he would be unable to duck under it where he was. As it looped about with another roar, he prodded Koros' flank with his heel and shouted a command.

The startled warbeast broke into a run, moving forward under the dragon's next howling lunge. This time the monster spat forth a jet of flame that seared the grass where the warbeast had stood a moment earlier, and Garth congratulated himself on his decision to dodge.

He watched intently as the creature turned again; it moved smoothly and gracefully, but was not actually very fast in maneuvering. It seemed unable to bank more than a few degrees; Garth guessed that, perhaps due to its size, it was not as stable in flight as a bird. A sufficient tilt might bring it down. He wondered if there were any way to use that against it, then forgot about aerodynamics as it swept down toward him again.

He sent Koros sideways this time, turning the warbeast out of its path. He misjudged slightly, or perhaps the dragon had allowed for his motion, and he felt the heat of its fiery breath at his back. Koros roared in pain; the fur of its tail had been singed.

Garth patted the warbeast, apologizing, as he considered the situation. The traditional method of dragon-slaying, according to legend, was to find some minute chink in the creature's armor and strike at it. He had seen no sign of any flaw in this dragon's defenses-but then, he had been too busy dodging to study it very closely. Still, the armor on this monster seemed almost unnaturally perfect-countless rows of fine golden scales in flawless, gleaming array.

The dragon was not making another attack, he realized; instead, it was circling, far out of reach. It appeared almost to be waiting for something, as if to see if the overman still intended to fight. Garth considered retreating, then dismissed the idea. When diving, the dragon moved with the speed of a falling stone, and it could probably catch him from behind before he could reach the forest. It might, he thought, be trying to coax him into just such a foolhardy maneuver.

He watched it wheel about, and an idea struck him. The thing was gigantic, and as it made the far part of its turn, he glimpsed its broad, smooth back, as wide and solid as the deck of a ship. If he could get atop it, he could hack at it at his leisure; with its limited aerodynamic ability, it might be unable to dislodge him. He had used a similar technique against a monster once before, the great worm that lived beneath Dыsarra; though that particular creature had not had the benefits of flight, flame, and armor.

The difficulty lay in getting onto the thing, but even that might not be impossible. He looked down at Koros' blackfurred back, shoulder muscles rippling under its hide as it shifted its stance. He had seen the warbeast leap to and from low rooftops, and bound over crowds of humans. It could almost certainly manage the jump he wanted.

Of course, he was not at all certain that he himself could manage his part of the feat he planned, but if he did not, it would probably mean nothing worse than a long fall. He could take a fall. He could see little to be lost by trying; the dragon could slay him just as easily if he did not make the attempt.

The dragon still circled smoothly in the sky above the mound; he turned the warbeast toward it and gave the command to charge.

Koros roared, so loudly that Garth's ears rang, and began bounding up the slope. Seeing this, the dragon turned and came to meet the overman and warbeast, bellowing and screaming and smoking like a burning city. As they drew nearer to one another, Garth gauged the distance carefully and, when he judged the moment to be right, shouted the command to leap.

Koros leaped, jaws wide and claws out, to attack the dragon; the warbeast was roaring with bloodlust. Garth felt the leap as a great surge upward; so smooth was the movement that he hardly realized when Koros left the ground. As the dragon loomed up before him, a gleaming coppery wall, he leaped himself, flinging himself upward from the saddle to grab at the monster's neck.

He struck hard against a shining red-gold flank and clung desperately, digging fingernails into the overlapping of the scales and scrambling upward with his feet.

His faithful mount, thrown off course by his own jump, hit the dragon full in the chest, then fell away, yowling with pain and anger, as its fangs and claws failed to penetrate and grip the gleaming armor.

Garth watched, concerned, as the warbeast fell. When Koros landed, catlike, on all fours and rose, apparently unhurt, Garth turned his attention back to his own situation with great relief.

He had a precarious purchase on the monster's shoulder, the wind whipping about him as the dragon sped through the skies. With all his superhuman strength, he forced himself upward against the hard scales and, with muscles straining, managed to haul himself up atop its back.

When he felt that he was reasonably secure between the mighty shoulders, he looked the beast over. He was surprised to discover that the scales felt fully as metallic as they looked.

The dragon seemed to be searching for something, looping back and forth across the mound and the meadow below, and Garth realized that it was unaware of his presence on its back.

It could feel nothing through its armor and thought that he, too, like Koros, had fallen.

He smiled, brushed aside a lock of black hair that had fallen into one eye, and drew his dagger. He had lost his sword in his leap, releasing it without conscious thought when he had to find a fingerhold, but his axe was slung across his back, and the dagger's sheath was secure on his belt. He set about prying at the scales on the back of the dragon's neck, wedging the point of the knife beneath their overlapped edges and working upward.

The scales tore loose and fell, tinkling down past the dragon's wings into space. To Garth's surprise, the monster did not react. He leaned forward to look at the spot of hide thus uncovered, as the wind of a high-speed turn lashed at him.

Beneath the scaly armor was a fine wire mesh, and beneath that, Garth could faintly make out a myriad of gears, chains, springs, and sprockets, ticking quietly.

He sat motionless for a moment, absorbing this discovery of the dragon's true nature. Quickly, he reached a decision; he could not kill this thing, obviously, and now he decided that he did not want to destroy it. He sat back and waited.

It was almost pleasant, crouching atop the broad metal back of the dragon as it swooped through the air. Garth had never flown before and found what little he could see from where he sat to be intriguing indeed. The wind was fresh and exhilarating when the monster was not in one of its sudden turns or dives, and the view was amazing.

He did not have to wait long; after a few more passes across the hillock and meadow, the dragon looped back up across the riverbank, then soared gracefully down into the gaping mouth of a cave on the eastern shore, at the base of the hillock. It braked by cupping its wings forward.

Inside the opening, it folded its wings and settled neatly to the ground, landing with a heavy thud and a mild bump. Then, in a scant second, it froze into total immobility, losing completely its incredible semblance of life and becoming a mere metal construct.

Garth glanced up and about and saw that the entire inside of the mound was hollow. Nor was it a natural cave; stone arches braced the ceiling, and niches were occupied by flaring oil lamps. Three young men stood off to one side, well away from the dragon; they had not yet noticed its unwanted passenger.
