The sounds of the battle behind became louder. Stile looked back — and saw a squadron of winged dragons coming from the south. The cyborgs fired bazookas at them. Their aim was excellent — but after the first few dragons went down in flames, the others took evasive action. They dived down close to the ground and strafed the cyborgs with their flaming breath. The goblins who had been engaging the cyborgs screamed; that strafing was hurting them, while the metal bodies of the machine-men withstood the heat better. The dragons might as well have been the cyborgs' allies.
"Keep moving," Sheen cautioned Stile. Indeed, he had become distracted by the action, forgetting his own important role. He hurried to place more plastic.
But haste made waste. They ran out of plastic and time before the job was done; several barriers remained. They had had enough of each, and had wasted part of both. "We must move," Sheen warned. "In ten minutes the plastic detonates, with or without us."
"Better head back for the ball," Stile said. "I want to be ready just before the plastic goes off, so we can start the ball rolling right at the moment of goblin disorganization."
They began running back toward the Phazite. New contingents of goblins were arriving from the north; they were swarming all over. Stile saw that the enemy was winning the battle of the hill; both animalheads and cyborgs were being contained and decimated. The goblins were absorbing huge losses, but prevailing because of their greater numbers and overall organization. A new force was advancing toward the Phazite. They would overrun the site before Stile could return.
"Conjure us there!" he cried.
"Can't," Sheen snapped. "The enemy Adepts have focused their full attention on this place, blocking off new magic. They're learning how to impede the potent book spells by acting together. This is the final squeeze, Stile."
"Then send my image there; that's an existing spell."
Suddenly his image was in the chamber. There were the Brown Adept and the troll, holding laser rifles clumsily, trying to oppose the advancing goblins. The remaining golems stood about awkwardly; their hands were not coordinated enough to handle modern weapons, and their wooden minds not clever enough to grasp this rapidly changing situation.
"That's no good," Stile said. "You can't stop a hundred vicious goblins by yourselves."
They looked at him, startled. "We feared for thee!" Brown exclaimed.
"Fear for thyself; they will be upon thee before I can return in the flesh. They want the book, and we must keep it away from them at any cost." Stile pondered a moment. "Trool — canst thou take Brown and the book into the tunnel and shield them with thine invisibility?"
Trool faded out. In a moment Brown faded out too. "Aye," his voice came. "But it is not safe in the tunnel, Adept; goblins are coming from the far end. We have blocked them off for the moment, but-"
"Canst thou fly with her to safety?" Stile cut in. Time was so short! "It need be but for a few minutes, until the explosive we have set goes off. Then will the enemy Adepts' attention be distracted, and we can use the spells of the book to protect ourselves."
"I will try," Trool's voice came. From several feet up, Brown cried, "Hey, this is fun!" Then they were out a ceiling aperture and away.
The goblins burst in, caving in the mound walls with pikes. They spied Stile and charged him — but their points had no effect on his image. On inspiration, he pretended that he could be hurt, and dodged about to avoid the thrusts, so as to distract them as long as possible. He didn't want them working on the Phazite ball, now vulnerable.
The golems were still standing awkwardly. Stile realized that they needed to be told what to do. "Protect yourselves!" he cried. "Golems, fight the goblins!"
Now the golems acted. They were neither smart nor swift, but they were as tough as wooden planks. The goblins swarmed over each golem and were hurled back violently. Yes, it was after all possible to make a decent fight of it!
Abruptly he was back with Sheen, at the base of the hill. The two of them were running through the battlefield, and it was grim. Goblins and animalheads lay dead and dying. This was where the animalheads had been fated to lose half their number, he realized. Some cyborgs were here too, their metal lying twisted and smoking; Stile saw one with its metal skull cracked open, the human brain exposed and shriveled. The odor of carnage was strong.
"We must find help," Sheen said, "to clean out the goblins and get the ball rolling."
"I wish we could save these creatures in pain," Stile said.
"We can't do it now. Once the ball crosses, we can."
Stile knew it was true. They had to move the ball first. Now only seconds remained before the plastic detonated.
They found a bearhead just recovering consciousness. Stile put his hand on the creature's shoulder, breaking the invisibility-spell for this one individual. "We need thee," Stile said. "Follow us."
"Aye, Blue," the bearhead agreed dizzily.
Sheen found a cyborg in the process of self-repair; it had lost a foot, but was affixing the foot of a dead cyborg in its place. Sheen introduced herself similarly. The four hurried on.
As they reached the crest of the hill, they smelled smoke. Something was burning in the mound. "The golems!" Sheen said grimly.
Stile winced. He knew the wooden golems were not truly alive, but surely they hurt when they burned. The goblins had used a devastating weapon, and the Brown Adept would be mortified.
They charged the mound, staring into its broken chamber. In the smoke of the golem bonfire, the goblins were trying to push the ball back into the spiral tube. The ball was shaking, starting to rock. Soon they would get it moving.
The four burst into the chamber. The goblins cried out and scattered as they saw the bearhead and cyborg, but rallied in a moment and drew their weapons. Stile and Sheen, invisible to them, knocked the pistols from the goblins' hands. Unable to fathom this new menace, the goblins nevertheless fought bravely, overwhelming their opposition, both visible and invisible, by force of numbers.
Then the plastic explosive detonated. The barrier wedges blew up, raining fiery pieces on the heads of the goblin army. The goblins in the mound disengaged and dashed out to see what new danger threatened. There was general disorganization.
"Now we roll it!" Stile cried. The four of them, joined by a charred but surviving golem, picked up the scattered limbs of golems and their tools and started levering the ball forward. They were more disciplined and purposeful than the goblins had been, and the ball was poised for this direction, but it was so massive they had just as much trouble budging it. "We need better levers!" Stile gasped. But he knew of none within range — and now they heard the goblins charging up the spiral tunnel. There was no time for a search.
A hawk flew into the chamber. "Clip!" Stile exclaimed. "What art thou doing here?"
The unicorn changed to man-form. "I knew thou wouldst foul it up by thyself, Adept," he said. "Mere men always do. So I brought some friends to bail thee out."
Now a bee, a hummingbird, and a blue heron flew in, changing to three more unicorns. The third had an iridescent mane. "Belle!" Stile said, recognizing her.
"She was wandering toward the battle," Clip said diffidently. "I could not leave her to such danger, and she does feel she owes thee, Adept, for the manner in which she was used to-"
"Yes, of course!" Stile agreed. "The four of you-help us push this ball down the hill!"
Clip shifted to equine form and played musical directions on his sax-horn. He was answered by a violin, tuba, and ringing-bell tune of agreement. The four put their horns carefully down into the crevice between ball and floor; then, musically coordinated, they levered up and forward.
