When they saw it, they jumped out of their dish and sank into the water. "Halt or I'll shoot," said the Iron Fley again, then hurled its spell. The dish shattered abruptly into small bits and a hissing cloud burst out of the water. The terrible creature circled over the floating fragments for a few minutes, then flew off upstream. When it was gone the seven magicians appeared, climbing out of the river on the far side. "Damn it!" said one. "A good boot lost, and not a bit of iron. I told you we ought to wait for night!" "It doesn't make any difference," said another gloomily. "It's always on watch. Nobody's gotten away with any iron for three or four seasons." "Well," said Alyar, after the magicians had straggled off down the river, "now we've seen it. It certainly put a powerful spell on that floating dish, but it didn't hurt the magicians. Maybe if we're careful it won't bother us." They followed the twisting canyon and eventually began to hear a roaring noise ahead. It turned out to be the water falling over a cliff, and to go any farther they had to climb out of the canyon again. When they were on top they could see, ahead of them, what was undoubtedly Iron Mountain. Parts of it were broken or rusted, but most of it was the non-rusting kind. Its shape was a surprise. It didn't look like a mountain, but something made by giants, broken off and stuck into the ground. It was wonderful to stand here, beholding the mightiest magic in the entire world. Still, Alyar wasn't satisfied. He felt he must go closer, even—possibly—touch it. "You'd better stay here. Bru, if anything happens to me, take the girls and run. You can get back to the beasts by going down the river." Bru was dismayed. "Don't go any closer! You saw what happened to the magicians' dish!" "They were trying to steal iron." He unloaded the metal he was carrying, smiled at them, and went on. He'd only covered a hundred man-lengths or so when he heard the distorted voice, coming from over his head. He looked up, then stood rooted as the Iron Fley came spiraling down toward him. He tried to think the purest, most serene thoughts he could, though the fervent wish to be somewhere else kept intruding.
