Neysa nodded, then walked to the center of the tunnel. Stile sang a spell to make himself invisible. This was external magic only; he remained just as solid as always, despite the change in appearance. He was getting accustomed to the limits of his power. When he lifted himself by magic he was changing his locale, not his body. He could not heal his own injured knees. He could not duplicate Neysa’s shape-changing or genuine insect-flying ability, though he could create the illusion of change in himself, and could fly artificially by magic means. There were some fine distinctions, but overall he was perhaps more vulnerable than Neysa, though he was also more powerful. When she saw he was unseeable, Neysa went into her act. “Oh!” she cried. “I’m so afraid! The horrible dragon is going to eat me!” She was really working at it, since she didn’t like to talk. Stile felt a warm glow of appreciation. Once Neysa had given him her loyalty, she had been the truest of companions.
Soon there was a rumbling deep in the tunnel. A hotter, ranker wash of air passed, as if some enormous engine had started up. Stile’s imperfect confidence suffered attrition. There were after all so many things that might go wrong ... Neysa continued lamenting. The rumble increased. The Worm must be afraid that the prey would flee if not quickly nabbed—a reasonable assumption. That was one important thing Stile wanted to know about it—how alert it was, and how fast it moved. A big, ponderous creature would be easier to handle than—
All too soon the Worm arrived. It was indeed a dragon. It had a long narrow head with a conical snout, narrowing in ringlike stages. The derivation of this monster from a literal worm was evident. Of course there were many kinds of worms; Stile tended to think of earthworms because many Citizens employed them in their elegant gardens. But he knew there were other types, some of them vicious. This dragon was a vicious worm grown monstrous. Neysa screamed realistically and skipped nimbly to the mouth of the passage. The Worm exhaled a puff of smog and slid forward. Its legs were puny compared to its bulk, not really used for its forward motion—but it did indeed have horrendous claws, and seemed to be fully adequate to the task of gutting a human being efficiently. Its metallic scales did not gleam; they were drab and dirty, more like the mud-caked treads of a caterpillar tractor. Stile did not doubt they were invulnerable to ordinary attack. Theoretically the point of a sword could be slid up under a layer of scales to penetrate the flesh beneath—but that could lead to a shallow slanting wound, only aggravating the monster. And what would the Worm be doing while the swordsman was making his insertion? Sitting still? Not likely! All of this. Stile realized abruptly, was academic. He did not have a sword. He had forgotten to conjure one. He had only the Platinum Flute and his magic—which magic it was time to use.
Stile’s strategy had been to bring the monster out to the front, then cast his spell from the rear. Now a problem manifested; the Worm had no rear. Its giant cylindrical torso extended back into the gloom. The shape of a worm, naturally—long. He should have known.
Well, he should be able to enchant it anyway. Stile played the Flute, and the perfect notes poured out again, emerging like quicksilver to fill the tunnel with beauty. The magic gathered swiftly, unusually intense. Of course; they were down near the Phazite lode, so the power was near at hand.
The dragon reacted instantly. No senile mentality here! It had been about to lunge at the supposedly helpless damsel—Neysa was playing it uncomfortably close—but recognized the summoning of magic here. The tiny armored eyes oriented on Stile—and did not see him, since he was invisible. Nevertheless the front orifice opened, its diameter cranking wider in several stages until it was a good yard across. From it a blast of hot fog bellied out. In this instant it occurred to Stile that the Worm had not tried to use heat on Neysa. Maybe it preferred its meals raw.
Time for self-defense. “From head to feet, immune to heat!” Stile sang.
But as the fog struck him, Stile discovered it was a false alarm. The stuff was hot but not burning. It was like being “p” in a polluted sauna.
The dragon heaved again. This time its breath was hotter and smelled worse. The creature was old; it took it time to get up full steam. The third blast was burning, and the fourth contained pure fire. From hair-dryer to flame-thrower, in easy stages!
Now for the attack. “O mighty Worm, complete thy term,” Stile chanted, willing instant death on it. Then something strange happened. There was a coruscation in the air midway between them, as of a beam of light striking a refractive barrier. The Worm did not die. Stile tried again. “O Worm of fire—weaken, expire!”
