# Chapter Four

MacIntyre felt numb.

"Wait," he said hoarsely. "Wait a minute! What about evolution? Damn it, Dahak, homo sapiens is related to every other mammal on the planet!"

"Correct," Dahak said unemotionally. "Following the First Imperium's fall, one of its unidentified non-human successor imperia re-seeded many worlds the Achuultani struck. Earth was one such planet. So also was Mycos, the true homeworld of the human race and the capital of the Second Imperium until its destruction some seventy-one thousand years ago. The same ancestral fauna were used to re-seed all Earth-type planets. Earth's Neanderthals were thus not ancestors of your own race but rather very distant cousins. They did not, I regret to say, fare well against Dahak's crew and its descendants."

"Sweet suffering Jesus!" MacIntyre breathed. Then his eyes narrowed. "Dahak, do you mean to tell me that you've sat on your electronic ass up here for fifty thousand years and done absolutely nothing?"

"That is one way of phrasing it," Dahak admitted uncomfortably.

"But why, goddamn it?!"

"What would you have had me do, Commander? Senior Fleet Captain Druaga issued Priority Alpha Category One orders to suppress the mutineers. Such priority one orders take absolute precedence over all directives with less than Alpha Priority and may be altered only by the direction of Fleet Central. No lesser authority—including the one that first issued them—may change them. Accordingly, Dahak has no option but to remain in this system until such time as all surviving mutineers are taken into custody or destroyed."

"So why didn't you seek new orders from this Fleet Central of yours?" MacIntyre grated.

"I cannot. Fleet Captain Anu's attack on Communications inflicted irreparable damage."

"You can rebuild three-hundred-plus fusion plants and you can't fix a frigging radio?!"

"The situation is somewhat more complicated than that, Commander," Dahak replied, with what MacIntyre unwillingly recognized as commendable restraint. "Supralight communication is maintained via the multi-dimensional communicator, commonly referred to as the 'hypercom,' a highly refined derivative of the much shorter-ranged 'fold-space' communicator used by Fleet personnel. Both combine elements of hyperspace and gravitonic technology to distort normal space and create a point-to-point congruence between distant foci, but in the case of the hypercom these distortions or 'folds' may span as many as several thousand light-years. A hypercom transmitter is a massive installation, and certain of its essential components contain Mycosan, a synthetic element that cannot be produced out of shipboard resources. As all spare components are currently aboard Fleet Captain Anu's parasites, repairs are impossible. Dahak can receive hypercom transmissions, but cannot initiate a signal."

"That's the only way you can communicate?"

"The Imperium abandoned primitive light-speed communications several millennia before the mutiny, Commander. Since, however, it was evident that repair of Dahak's hypercom was impossible and no Fleet unit had been sent to investigate Dahak's original malfunction report, Comp Cent constructed a radio transmitter and sent a report at light speed to the nearest Fleet base. It is improbable that the Imperium would have abandoned a base of such importance, and Comp Cent therefore concluded that the message was not recognized by its intended recipients. Whatever the reason, Fleet Central has never responded, thus precluding any modification of Dahak's Alpha Priority instructions."

"But that doesn't explain why you didn't carry out your original orders and blast the bastards as they left the ship!" MacIntyre snarled venomously.

"That is an incorrect interpretation of Comp Cent's orders, Commander. Senior Fleet Captain Druaga's instructions specified the destruction of mutinous vessels approaching within five thousand kilometers; they did not specify the destruction of mutinous vessels departing Dahak."

"They didn't—!" MacIntyre stopped himself and silently recited the names of the Presidents. "All right," he said finally, "I can accept that, I suppose. But why haven't you blasted them off the planet since? Surely that comes under the heading of taking them into custody or destroying them?"

"It does. Such action, however, would conflict with Alpha Priority core programs. This vessel has the capacity to penetrate the defenses Fleet Captain Anu has established to protect his enclave, but only by using weaponry that would destroy seventy percent of the human race upon the planet. Destruction of non-Achuultani sentients except in direct self-defense is prohibited."

"Well, what have they been doing all this time?"

"I cannot say with certainty," Dahak admitted. "It is impossible for my sensors to penetrate their defensive systems, and it is apparent that they have chosen to employ a substantial amount of stealth technology. Without observational data of their inner councils, meaningful analysis is impossible."

"You must have some idea!"

"Affirmative. Please remember, however, that all is speculation and may be offered only as such."

"So go ahead and speculate, damn it!"

"Acknowledged," Dahak said calmly. "It is my opinion that the mutineers have interacted with Terra-born humans since such time as your planetary population attained sufficient density to support indigenous civilizations. Initially, this contact was quite open, leading to the creation of the various anthropomorphic pantheons of deities. Interaction with your own Western Civilization, however, particularly since your sixteenth century, has been surreptitious and designed to accelerate your technical development. Please note that this represents a substantive change in the mutineers' original activities, which were designed to promote superstition, religion, and pseudo-religion in place of rationalism and scientific thought."

"Why should they try to slow our development?" MacIntyre demanded. "And if they did, why change tactics?"

"In my opinion, their original intent was to prevent the birth of an indigenous technology that might threaten their own safety, on the one hand, or attract the Achuultani, on the other. Recall that their original motive for mutiny was to preserve themselves from destruction at Achuultani hands.

"Recently, however—" MacIntyre winced at hearing someone refer to the sixteenth century as "recently" "—the focus of their activities has altered. Perhaps they believe the incursion they feared has already occurred and that they are therefore safe, or perhaps there has been a change in their leadership, leading to changes in policy. My opinion, however, is that they have concluded that Dahak is not and will not again become fully operational."

"What? Why should that matter?"

"It would matter if they assume, as I am postulating that they have, that sufficient damage was inflicted upon Dahak's power generation capacity as to preclude repairs. Fleet Captain Anu cannot know what Senior Fleet Captain Druaga's final instructions were. As he is unaware that Senior Fleet Captain Druaga's Alpha Priority orders have required Dahak to remain on station, he may well conclude that Dahak's failure to depart in search of assistance indicates that supralight travel is no longer possible for Dahak. Yet if there were sufficient power for repairs, Dahak would be supralight-capable, as there was never an actual failure of the Enchanach Drive. Dahak's very presence here may thus be construed as empirical evidence of near-total incapacity."

"So why not come out and grab you?"

"Because he has conclusive evidence that sufficient power does remain for pre-programmed defensive fire plans, yet no fire has been directed against the primitive spacecraft Terra-born humans have dispatched to their 'moon.' Accordingly, he may believe Dahak's command capabilities are too deeply impaired to re-program those defensive fire plans and that those plans do not provide for interference with locally-produced spacecraft. Assuming this entirely speculative chain of reasoning is correct, he may well hope to push your planet into developing interstellar craft in order to escape this star system. This theory is consistent with observed facts, including the world wars and Soviet-American 'cold war' of the twentieth-century, which resulted in pressurized research and development driven by military requirements."

"But the cold war ended decades ago," MacIntyre pointed out.

"Agreed. Yet that, too, is consistent with the theory I have offered. Consider, Commander: the superpowers of the last century have been drawn together in cooperation against the growing militancy of your so-called Third World, particularly the religio-political blocs centered on radical Islam and the Asian Alliance. This has permitted the merger of the First World technical base—ConEuropean, Russian, North American, and Australian—Japanese alike—while maintaining the pressure of military need. In addition, certain aspects of Imperial technology have begun to appear in your civilization. Your gravitonic survey instruments are a prime example of this process, for they are several centuries in advance of any other portion of your technology."

"I see." MacIntyre considered the computer's logic carefully, so caught up in Dahak's story he almost forgot his own part in it. "But why push for starships? Why not just use a 'locally-produced' ship to take you over?"

"It is possible that he intends to do precisely that, Commander. Indeed, had your vessel not fired upon mine, I might have taken your sub-surface survey device as just such an attempt, in which case I would have destroyed you." MacIntyre shivered at how calmly Dahak spoke. "My preliminary bio-scans indicated that you were not yourself a mutineer, but had you demanded entry, had you failed to resist—had you, in fact, done anything that indicated either an awareness of Dahak's existence or a desire to enter—my core programming would have assumed at least the possibility that you were in Fleet Captain Anu's service. That assumption would have left me no choice but to destroy you as per Senior Fleet Captain Druaga's final directives.

"However," the computer continued serenely, "I do not believe he would make that attempt. Either Dahak had sufficient power to repair the damage, in which case the ship is, in fact, fully operational and would destroy him or his minions, or else Dahak had insufficient power to decontaminate the vessel's interior, in which case re-entry would remain effectively impossible without Imperial technology—which would activate any operational defensive programming." The computer's voice gave MacIntyre the strong impression of a verbal shrug. "In either case, Dahak would be useless to him."

"But he expects you to let locally-produced starships get away from you?" MacIntyre asked skeptically.

"If," Dahak said patiently, "this unit were, indeed, no longer fully operational, automatic defensive fire plans would not be interested in vessels leaving the star system."

"But you aren't inoperative, so what would you do?"

"I would dispatch one or more armed parasites to bio-scan range and scan their personnel. If mutineers were detected on board them, I would have no choice but to destroy them."

MacIntyre frowned. "Uh, excuse me, Dahak, but wouldn't that be a rather broader interpretation of your orders? I mean, you let the mutineers escape to the planet because you hadn't been ordered to stop them, right?"

"That is correct, Commander. It has occurred to me, however, that Comp Cent's original interpretation of Senior Fleet Captain Druaga's orders, while essentially correct, did not encompass Senior Fleet Captain Druaga's full intent. Subsequent analysis suggests that had he known the mutineers would employ parasites so readily distinguishable from the loyal crew's lifeboats, he would have ordered their immediate destruction. Whether or not this speculation is correct, the fact remains that no mutineer may be allowed to leave this star system by any means. Allowing any mutinous personnel to escape would conflict with Dahak's Alpha Priority orders to suppress the mutiny."

"I can see that," MacIntyre murmured, then paused, struck by a new thought. "Wait a minute. You say Anu's assumed you're no longer operational—"

"Incorrect, Commander," Dahak interrupted. "I stated that I have speculated to that effect."

"All right, so it's speculative. But if he has, haven't you blown it? You couldn't have grabbed my Beagle if you were inoperative, could you?"

"I could not," Dahak conceded, "yet he cannot be certain that I did so."

"What? Well then, what the hell does he think happened?"

"It was my intention to convince him that your vessel was lost due to an onboard malfunction."

"Lost?" MacIntyre jerked up in his couch. "What d'you mean, 'lost'?"

"Commander," Dahak said almost apologetically, "it was necessary. If Fleet Captain Anu determines that Dahak is indeed functional, he may take additional protective measures. The destruction of his enclave's present defenses by brute force would kill seventy percent of all Terran humans; if he becomes sufficiently alarmed to strengthen them still further the situation may well become utterly impossible of resolution."

"I didn't ask why you did it!" MacIntyre spat. "I asked what you meant by 'lost,' goddamn it!"

Dahak did not answer directly. Instead, MacIntyre suddenly heard another voice—his voice, speaking in the clipped, emotionless tones every ex-test pilot seems to drop into when disaster strikes.

" . . . ayday. Mayday. Heinlein Base, this is Papa-Mike One-X-Ray. I have an explosion in number three fuel cell. Negative function primary flight computers. I am tumbling. Negative response attitude control. I say again. Negative response attitude control."

"Heinlein copies, One-X-Ray," a voice crackled back. He recognized that soft Southern accent, he thought in a queerly detached way. Sandy Tillotson—Lieutenant Colonel Sandra Tillotson, that was. "We have you on scope."

"Then you see what I see, Sandy," his own voice said calmly. "I make it roughly ten minutes to impact."

There was a brief pause, then Tillotson's voice came back, as flat and calm as "he" was.

"Affirmative, Colin."

"I'm gonna take a chance and go for crash ignition," his voice said. "She's tumbling like a mother, but if I can catch her at the right attitude—"

"Understood, Colin. Luck."

"Thanks. Coming up on ignition—now." There was another brief pause, and then he heard "himself" sigh. "No joy, Sandy. Caught it wrong. Tell Sean I—"

And then there was only silence.

* * *

MacIntyre swallowed. He had just heard himself die, and the experience had not been pleasant. Nor was the realization of how completely Dahak had covered its tracks. As far as any living human knew, Lieutenant Commander Colin MacIntyre no longer existed, for no one would wonder what had become of him once they got to the crash site. Somehow he never doubted there would be a crash site, but given the nature of the "crash" he'd just listened to, it would consist of very, very tiny bits and pieces.

"You bastard," he said softly.

"It was necessary," Dahak replied unflinchingly. "If you had completed your flight with proof of Dahak's existence, would not your superiors have mounted an immediate expedition to explore your find?" MacIntyre gritted his teeth and refused to answer.

"What would you have had me do, Commander? Fleet Captain Anu could not enter this vessel using the parasites in which he escaped to Earth, but could I know positively that any Terra-born humans sent to explore Dahak's interior had not been suborned by him? Recall that my own core programming would compel me to consider that any vessel that deliberately sought entry but did not respond with proper Fleet authorization codes was under mutinous control. Should I have allowed a situation in which I must fire on every ship of any type that came near? One that would also require me to destroy every enclave your people have established on the lunar surface? You must realize as well as I that if I had acted in any other way, Fleet Captain Anu would not merely suspect but know that Dahak remains operational. Knowing that, must I not assume that any effort to enter Dahak—or, indeed, any further activity on the lunar surface of any type whatever—might be or fall under his direct control?"

MacIntyre knew Dahak was a machine, but he recognized genuine desperation in the mellow voice and, despite himself, felt an unwilling sympathy for the huge ship's dilemma.

He glared down at his clenched fists, bitter anger fighting a wash of sympathetic horror. Yes, Dahak was a machine, but it was a self-aware machine, and MacIntyre's human soul cringed as he imagined its endless solitary confinement. For fifty-one millennia, the stupendous ship had orbited Earth, powerful enough to wipe the planet from the face of the universe yet forever unable to carry out its orders, caught between conflicting directives it could not resolve. Just thinking of such a purgatory was enough to ice his blood, but understanding didn't change his own fate. Dahak had "killed" him. He could never go home again, and that awareness filled him with rage.

The computer was silent, as if allowing him time to come to grips with the knowledge that he had joined its eternal exile, and he clenched his fists still tighter. His nails cut his palms, and he accepted the pain as an external focus, using it to clear his head as he fought his emotions back under control.

"All right," he grated finally. "So what happens now? Why couldn't you just've killed me clean?"

"Commander," Dahak said softly, "without cause to assume your intent was hostile, I could not destroy your vessel without violating Alpha Priority core programming. But even if I could have, I would not have done so, for I have received hypercom transmissions from unmanned surveillance stations along the traditional Achuultani incursion routes. A new incursion has been detected, and a Fleet alert has been transmitted."

MacIntyre's face went white as a far more terrible horror suddenly dwarfed the shock and fury of hearing himself "die."

"Yet I have monitored no response, Commander," the computer said even more softly. "Fleet Central is silent. No defensive measures have been initiated."

"No," MacIntyre breathed.

"Yes, Commander. And that has activated yet another Alpha Priority command. Dahak is a Fleet unit, aware of a threat to the existence of the Imperium, and I must respond to it . . . but I can not respond until the mutiny is suppressed. It is a situation that cannot be resolved by Comp Cent, yet it must be resolved. Which is why I need you."

"What can I do?" MacIntyre whispered hoarsely.

"It is quite simple, Commander MacIntyre. Under Fleet Regulation Five-Three-Three, Subsection Nine-One, Article Ten, acting command of any Fleet unit devolves upon the senior surviving crewman. Under Fleet Regulation Three-Seven, Subsection One-Three, any descendant of any core crewman assigned to a vessel for a given deployment becomes a crew member for the duration of that deployment, and Senior Fleet Captain Druaga's deployment has not been terminated by orders from Fleet Central."

MacIntyre gurgled a horrified denial, but Dahak continued mercilessly.

"You, Commander, are directly descended from loyal members of Senior Fleet Captain Druaga's core crew. You are on board Dahak. By definition, therefore, you become the senior member of Dahak's crew, and thus—"

MacIntyre's gurgling noises took on a note of dreadful supplication.

"—command devolves upon you."

* * *

He argued, of course.

His sense of betrayal vanished, for it seemed somehow petty to worry about his own fate in the face of catastrophe on such a cosmic scale. Yet the whole idea was . . . well, it was preposterous, even if that was a word he'd been over-using of late. He was absolutely, totally, beyond a shadow of a doubt, utterly unqualified for the job, and he told Dahak so.

But the old ship was stubborn. He was, the computer argued, a trained spacecraft pilot with a military background and a command mentality. Which, MacIntyre pointed out acidly, was to say that he was well-qualified to paddle aboriginal canoes and about as well-versed in FTL tactics as a Greek hoplite. But, Dahak countered, those were merely matters of education; he had the proper mental orientation. And even if he had not had it, all that really mattered was that he had the rank for the job. Which, MacIntyre retorted, was merely to say that he was a member of the human race. Except, Dahak rejoined, that he was the first member of the human race to re-embark in Dahak, which gave him seniority over all other Terrans—except, of course, the mutineers who, by their own actions, had forfeited all rank and crew status.

It went on for hours, until MacIntyre's voice was hoarse and exhaustion began to dull his desperate determination to squirm out of the responsibility. He finally offered to accept command long enough to turn it over to some better-qualified individual or group, but Dahak actually sounded a bit petulant when it rejected that suggestion. MacIntyre was the first human aboard in fifty-one thousand years; ergo he had the seniority, he always would have the seniority, and no substitutions were acceptable.

It really was unfair, MacIntyre thought wearily. Dahak was a machine. It—or "he," as he'd come to think of the computer—could go right on arguing until he keeled over from exhaustion . . . and seemed quite prepared to do so.

MacIntyre supposed some people would jump at the chance to command a ship that could vaporize planets—which was undoubtedly an indication that they shouldn't be offered it—but he didn't want it! Oh, he felt the seductive allure of power and, even more, the temptation to cut ten or fifteen thousand years off Terran exploration of the universe. And he was willing to admit someone had to help the old warship. But why did it have to be him?!

He lay back, obscurely resentful that his chair's self-adjusting surface kept him from scrunching down to sulk properly, and felt six years old again, arguing over who got to be the sheriff and who had to be the horse thief.

The thought made him chuckle unwillingly, and he grinned, surprised by his own weary humor. Dahak clearly intended to keep on arguing until he gave in, and how could he out-wait a machine that had mounted its own lonely watch for fifty millennia? Besides, he felt a bit ashamed even to try. If Dahak could do his duty for that tremendous stretch of time, how could MacIntyre not accept his own responsibility to humankind? And if he was caught in the Birkenhead drill, he could at least try to do his best till the ship went down.

He accepted it, and, to his surprise, it was almost easy. It scared the holy howling hell out of him, but that was another matter. He was, after all, a spacecraft command pilot, and the breed was, by definition, an arrogant one. MacIntyre had accepted long ago that he'd joined the Navy and then transferred to NASA because deep inside he had both the sneaking suspicion he was equal to any challenge and the desire to prove it. And look where it had gotten him, he thought wryly. He'd sweated blood to make the Prometheus Mission, only to discover that he'd anted up for a far bigger game than he'd ever dreamed of. But the chips were on the table, and other cliches to that effect.

"All right, Dahak," he sighed. "I give. I'll take the damned job."

"Thank you, Captain," Dahak said promptly, and he shuddered.

"I said I'd take it, but that doesn't mean I know what to do with it," he said defensively.

"I am aware of that, Captain. My sensors indicate that you are badly in need of rest at the moment. When you have recovered your strength, we can swear you in and begin your education and biotechnic treatments."

"And just what," MacIntyre demanded warily, "might biotechnic treatments be?"

"Nothing harmful, Captain. The bridge officer program includes sensory boosters, neural feeds for computer interface, command authority authentication patterns, Fleet communicator and bio-sensor implants, skeletal reinforcement, muscle and tissue enhancement, and standard hygienic, immunization, and tissue renewal treatments."

"Now wait a minute, Dahak! I like myself just the way I am, thank you!"

"Captain, I make all due allowance for inexperience and parochialism, but that statement cannot be true. In your present condition, you could lift barely a hundred and fifty kilos, and I would estimate your probable life span at no more than one Terran century under optimal conditions."

"I could—" MacIntyre paused, an arrested light in his eyes. "Dahak," he said after a moment, "what was the life expectancy for your crewmen?"

"The average life expectancy of Fleet personnel is five-point-seven-nine-three Terran centuries," Dahak said calmly.

"Uh," MacIntyre replied incisively.

"Of course, Captain, if you insist, I will have no choice but to forgo the biotechnic portion of your training. I must respectfully point out, however, that should you thereafter confront one of the mutineers, your opponent will have approximately eight times your strength, three times your reaction speed, and a skeletal muscular structure and circulatory system capable of absorbing on the order of eleven times the damage your own body will accept."

MacIntyre blinked. He was none too crazy about the word "biotechnic." It smacked of surgery and hospital time and similar associated unpleasantnesses. But on the other hand . . . yes, indeedy deed. On the other hand. . . .

"Oh, well, Dahak," he said finally. "If it'll make you happy. I've been meaning to get back into shape, anyway."

"Thank you, Captain," Dahak said, and if there was a certain smugness in the computer's bland reply, Acting Senior Fleet Captain Colin MacIntyre, forty-third commanding officer of Imperial Fleet Unit Dahak, hull number 172291, chose to ignore it.
