Nevertheless, he had not yet reached the end of the passageway that opened onto the central power chamber when a new alarm went off, this one directly ahead and localized. Then he heard explosions and smelled the raw burn of magic, and he realized that another had gotten to the chamber ahead of him. Pulling Ryer Ord Star after him, not quite certain what he was going to find, he began to run. It was as apt to be the Ilse Witch as one of his companions. The sounds of battle were unmistakable, however, as machines shattered and glass exploded out of walls. Bits and pieces of creepers flew across the passageway entrance as he neared the power chamber, where smoke roiled through a surreal landscape of flameless lamps and fire threads.
He glanced back at Ryer Ord Star. The exhilaration was gone from her face, the joy from her eyes. Desperation had replaced both, born of more than her recognition of the obvious dangers that waited. It was as if she had divined both his intent and her complicity in advancing it by saving him earlier. Her face was pale and taut, and her silver hair flew out behind her in a thin curtain, lending her a ghostly look. She tried to say something, but saw the intensity of his expression and kept still.
They burst through the power source entry into a vast chamber dominated by a pair of towering cylinders situated in the center of the room and connected everywhere by pipes and conduits. Smaller machines surrounded them, metal cages and housings bristling with flexible lines. Walker had no idea how they worked, how Antrax fed, how it converted magic to a fuel it could consume. The technology for the process had been dead for more than two and a half millennia, and only Antrax itself possessed the knowledge to keep it operating. That was true of the lifeblood that fed Antrax and preserved the library of the Old World. Destroy either, and you destroyed both.
It was what Walker had come to realize he must do, a sacrifice of one to put an end to the other.
He no longer thought to debate the matter. He knew that Antrax would eventually reach out for other sources of magic, other magic-infused humans, and the cycle would begin again. Sooner or later, it would siphon off everything of worth from the world that had replaced the one Antrax had served, and all to preserve a machine that no longer mattered. Antrax must be stopped, destroyed while there was still time.
Fire threads ringed the cylinders that formed the power source, shifting at random this way and that, keeping at bay anything that might try to harm the capacitors they protected. Smoke clouded the chamber in a thick haze, giving everything the appearance of a nightmarish netherworld. The creepers that appeared out of its brume had the look of shades, and even the equipment seemed to shift and turn in the mix of light and shadow.
Then abruptly, out of nowhere, Ahren Elessedil appeared, hands stretched forth as if to ward off invisible things, slender body taut and gathered to strike as he stepped gingerly through the debris. Blue light flashed from between his fingers, shattering creepers that crossed his path, clearing the way forward. Walker felt a surge of renewed hope. The Elven Prince had managed to recover the missing Elfstones, something he had not dared to hope could happen. With their magic to aid his own, he would have a better chance to succeed in doing what was needed.
“Ahren!” Ryer Ord Star shouted out even before Walker could speak.
The Elven Prince turned toward them, his eyes as blue and wild as the fire of the Stones. He registered the presence of Walker and the seer but only barely. He was consumed by the magic, so caught up in its throes that all that mattered to him, all that he could feel, was the rush of its power through his body.
Walker moved toward him swiftly, unafraid of the dark look in his eyes, of the blue fire gathered at his clenched fists. He reached out for the Elven Prince and touched him lightly, drawing him out from the haze into which he had been carried, bringing him back to himself. Ahren stared at him in anger, then confusion, then with undisguised relief.
“You’ve done well, Elven Prince,” Walker said, drawing him close, eyes shifting this way and that for the enemies that circled all around them. “Draw the magic back into yourself. Quickly!”
Walker watched the blue light of the Elfstones fade, then cloaked Ahren with concealing magic, as well. “Come this way.”
Aware that Antrax was searching, he moved Ahren and Ryer to one side, changing their position in the chamber. He had thrown out images and set off the alarms on the pressure plates that Antrax had activated earlier, confusing things further. The sirens shrilled everywhere, and warning lights on wall panels flashed like red eyes blinking through the cross-hatching of the fire threads. Momentarily confused, the creepers shifted this way and that. They could not find either the Druid or his companions; in the chaos, their sensors were unable to fix on anything.
Walker had drawn the Elf and the seer all the way back to the partially shattered wall of the extraction chamber, where they would have some protection. “Wait for me here,” he ordered.
Gathering his robes about him, he slipped away from them, maneuvering past the creepers toward the cylinders that warded the power source. There was no time left for subtlety. He would have to strike quickly. He found a seam in the plating, a weakness that might be exploited, and attacked. Druid fire rent the metal with a withering blast, peeling it away. Before Antrax could react, Walker moved again. A dozen yards farther on, he struck once more. Then the fire threads were seeking him, striking at random because they were unable to fix on him within his covering of magic. He dodged them as he attacked, avoiding the creepers, as well, circling the cylinders and surrounding machinery, continually seeking vulnerable points.
Yet despite his best efforts, the protective metal of the power source held firm. He was depleting his strength, but gaining no advantage. Another way must be found. Still throwing out distractions and false targets, he moved back across the floor, barely escaping a random fire thread that singed his cloak. Sooner or later, his luck would run out. Antrax would already be mounting a counterattack.
He barely finished the thought before the attack began. A beam of oddly hazy light radiated from a port high in the ceiling, flooding the room and outlining Walker where he crouched. If he had not already been moving, leaving images in his wake, he would have been incinerated by the fire threads that shifted instantly to find him. As it was, he was pinned between two of the smaller machines, unable to move anywhere as the creepers, able to pinpoint him at last, closed in for the kill.
Seeing the danger, Ahren Elessedil stepped away from Ryer Ord Star and turned the magic of the Elfstones on the port that had released the revealing light, shattering it, then fusing it shut. The light faded, and Walker was up and moving once more. Ahren struck out at the closest of the creepers, clearing a path for the Druid, giving him a chance to escape. Walker raced to join him, grabbed his arm, and pulled him back against the wall again. Throwing out a new set of distractions, he dragged both Elven Prince and seer into the doorway of the extraction chamber.
“Stand here!” he shouted into Ahren’s ear over the din. “Hold them back for as long as you can—then run!”
He turned into the room, searching out the power feeds that were built into the wall. He had been going about the battle in the wrong way. He could not attack the power source from without; whoever had constructed Antrax would have made certain that sabotage of that sort was very difficult. Any permanent damage would have to come from within. Antrax had been installed inside Castledown to protect the library of the Old World against attacks from without. There would be internal defenses, as well, but they would not be as substantial. The intake lines that fed raw power into the capacitors for conversion and storage would have near-infinite capacity, since such power would necessarily come in different forms and increments.
