Where did Antrax dwell within this vast complex?
Where did all the information feed?
He tracked it for a time, down lines and through chambers, along corridors and around corners. But one set of relays led to another. One bank of machines was tied to a second. Lines of power opened into new lines, and there was no end of them. Nothing to tell him where to find the start and finish of things.
He tried quieting himself and tracking Antrax by feel. It was not difficult to do. But once again, there seemed to be no start or finish. Antrax was vast and sprawling. It was everywhere at once, all about and seeping through, endless and immutable. Antrax was the safehold of Castledown; spread in equal parts throughout, there was no part of the keep that it did not inhabit. It warded everything at once.
Walker did not waver from his goal. He had come too far to give up. There was too much at stake and no one else who could do what was needed. Not even …
He hesitated. The words were bitter with realities he did not want to face.
Yet what choice did he have?
He finished the sentence in a rush. Not even her.
He must change his thinking, he acknowledged in what, for some, might have been considered an admission of defeat. But Druids dealt with neither victory nor defeat, but with reality and truth. What was fated could not be denigrated or altered by imposition of moral judgment. It was not his mandate. Druids served a higher cause, the preservation and advancement of Mankind and the Races. The Great Wars had reduced civilization to ruins and humans to animals. That must not happen again. The Druid Council had been formed in the time of Galaphile to see that it could not, and every Druid since had worked in furtherance of that end.
But what could he accomplish in the time that remained to him? There, in that nightmarish place, with only a few to stand beside him, with so much at stake? What, that would give life to the bargain he had struck with Allardon Elessedil all those months ago?
Time was slipping away, time he could not afford to waste. He was taking the wrong approach to the business, he decided. His search for answers was leading him in the wrong direction. It was not Antrax that had brought him to Castledown in the first place. Antrax was a secondary concern. It was the treasure Antrax warded that mattered, that could change everything.
He must look for the books of magic.
Pervasive in presence and reach, Antrax sprawled in contented solitude across the vast complex of its underground kingdom, monitoring its sensors and readouts, fulfilling functions its creators had programmed. With the blind certainty of artificial intelligence, it relied on the reassurance of constant input and an unchanging environment. For not quite three thousand years, it had maintained its world through its preassigned functions and unswerving vigilance. Any possibility of disruption brought a swift response.
Such a possibility had just drawn Antrax’s attention. It was still tiny and signified nothing as yet, but it was there nevertheless. It wasn’t a wave so much as a ripple in the lines of power, undetectable by the warning systems that warded Castledown, virtually immeasurable as an electronic current denoting life, more like a shadow that changed light to dark and dropped the temperature a fraction of a degree. Antrax was alerted to the unexplained presence mostly because it was still searching for two of the intruders whose magic it coveted. While it held one imprisoned in dreams and fantasies, draining it of the power it possessed, assimilating it into Castledown’s power cells, the others continued to elude it. Its wronk still hunted the second, tracking it relentlessly through the forest that bordered Castledown. The readouts were steady and unchanged, so there could be no question that the wronk was still functioning properly. It would have its quarry before long.
The third, on the other hand, was proving to be an enigma that Antrax was not able to solve. That one had followed the metal probe into Castledown’s warren without resistance, but then something had happened to startle it, and it had bolted. Since then, it had managed to hide itself despite everything Antrax had done to find it. Heat and movement sensors, pressure pads, trip ports, and sound detectors had failed to uncover it. Lasers and metal probes had scoured the corridors and chambers of the complex without result. It was possible that it had escaped Castledown entirely, but there was nothing to confirm that. Antrax wanted this one in particular because it was needed to replace the intruder that had failed and been sent back as a lure. No other was suited for the drawing down of power from the blue stones. Only the one who was missing.
Nothing had ever evaded Antrax for so long. Could it be that the odd ripple it felt in the lines of power was the third intruder, changed in form? Did it possess such power, such adaptability, when the other had not? Evolution was a fact of life, of the human condition, so perhaps it was so.
Antrax extended itself through its sensors and detectors, through all its communicators, searching. It went everywhere at once, monitoring readouts. Its examination took a long time, but time was something of which it had plenty. It explored the skin of its walls and floors and ceilings as would a living creature, making certain it was whole and free of clinging debris and secreting, burrowing minutiae.
Nothing revealed itself.
All of its metal probes responded to its inquiries regarding their operability. None were broken or disrupted, where such would signal a foreign presence. Nor did the lasers register any problem. Even the vast complex that housed the recordings of the creators hummed steadily along in its transference of information from one storage unit to another, keeping fresh, keeping whole. No system failed to respond when checked. All was as it should be.
Yet something was out of place.
Antrax took readings on the intruder housed in Extraction Chamber Three. The expulsion of power into the cells was noticeably down, but the intruder was still strapped in place and the wires that monitored its bodily functions had not been tampered with. Heat sensors indicated normal temperature readings for the room and no other presence. His prisoner seemed to be resting, asleep perhaps, though that rarely happened with the extraction techniques used by Antrax. Antrax paused to consider the readings more closely. The expected bursts of power in response to perceived threats had diminished noticeably. But that could be a result of exhaustion or even the extraction machine’s determination of the subject’s need for a respite. Draining off power was a delicate process, requiring a careful monitoring of the mental and emotional condition of the victim. Antrax had learned that humans were creatures of infinite possibility if kept whole. But flesh and blood were not as durable as metal. The creators had demonstrated that.
Sometimes Antrax wished the creators would return, though less so than in the beginning. At first, it had felt they must, that the creators were essential to its ultimate survival. Later, it had discovered how well it could survive on its own. Later still, the importance of the creators had diminished to such a degree that it saw them as unnecessary.
Yet it would house and protect their recordings, awaiting their return, because that was its mandate and prime directive. Survival was assured so long as there were sources of power to draw upon and ways to gain control over them. For Antrax, that was not so difficult a task. If not one way, then another. If not by securing them here, then by tracking them there.
After all, even for an artificial intelligence of its size and capacity, there were ways to leave Castledown.
Antrax took a moment longer to consider the readouts on its prisoner, and then spun slowly back through its network of living metal threads, searching.
Cloaked in the magic of the phoenix stone, wrapped in the blanket of his thoughts, Ahren Elessedil stood close to the table on which Walker and Ryer Ord Star lay entwined. He had been waiting and watching for what seemed like an impossibly long time, and he was growing restless. Something was nudging at him, a sense of dissatisfaction with his role as observer, a feeling of opportunity slipping away. He needed to be doing something.
