Mutineer's Moon

“Fifth planet?” MacIntyre parroted, overloaded by what he was hearing. “You mean …?”

“Precisely, Commander: the asteroid belt. It would appear they struck your fifth planet a bit harder than Earth, and it was much smaller and less geologically stable to begin with.”

“Are you sure?”

“I have had sufficient time to amass conclusive observational data. In addition, such an act would be consistent with recorded Achuultani tactics and the deduced military policies of the First Imperium, which apparently preferred to place system defense bases upon centrally-located non-life-bearing bodies.”

Dahak paused, and MacIntyre sat silent, trying to grasp the sheer stretch of time involved. Then the computer spoke again.

“Shall I continue?” it asked, and he managed another nod.

“Thank you. Imperial analysts speculate that the periodic Achuultani incursions into this arm of the galaxy represent sweeps in search of potential competitors—what your own military might term ‘search and destroy’ missions—rather than attempts to expand their imperial sphere. The Achuultani culture would appear to be extremely stable, one might almost say static, for very few technological advances have been observed since the Second Imperium. The precise reasons for this apparent cultural stasis and for the widely varying intervals between such sweeps are unknown, as is the precise locus from which they originate. While some evidence does suggest an extra-galactic origin for the species, pattern analysis suggests that the Achuultani currently occupy a region far to the galactic east. This, unfortunately, places Sol in an extremely exposed position, as your solar system lies on the eastern fringe of the Imperium. In short, the Achuultani must pass Sol to reach the Imperium.

“This has not mattered to your planet of late, as there has been nothing to attract Achuultani attention to this system since the end of the First Incursion. That protection no longer obtains, however. Your civilization’s technical base is now sufficiently advanced to produce an electronic and neutrino signature that their instruments cannot fail to detect.”

“My God!” MacIntyre turned pale as the implications struck home.

“Precisely, Commander. Your sun’s location also explains Dahak’s presence in this region. Dahak’s mission was to picket the Noarl System, directly in the center of the traditional Achuultani incursion route. Unfortunately—or, more precisely, by hostile design— Dahak suffered catastrophic failure of a major component of its Enchanach Drive while en route to its intended station, and Senior Fleet Captain Druaga was forced to stop here for repairs.”

“But if the damage was repairable, why are you still here?”

“Because there was, in fact, no damage.” Dahak’s voice was as measured as ever, but MacIntyre’s hyper-sensitive mind seemed to hear a hidden core of anger. “The ‘failure’ was contrived by Dahak’s chief engineer, Fleet Captain (Engineering) Anu, as the opening gambit in a mutiny against Fleet authority.”

“Mutiny?”

“Mutiny. Fleet Captain Anu and a minority of sympathizers among the crew feared that a new Achuultani incursion was imminent. As an advanced picket directly in the path of any such incursion, Dahak would very probably be destroyed. Rather than risk destruction, the mutineers chose to seize the ship and flee to a distant star in search of a colonizable planet.”

“Was that feasible?” MacIntyre asked in a fascinated tone.

“It was. Dahak’s cruising radius is effectively unlimited, Commander, with technical capabilities sufficient to inaugurate a sound technology base on any habitable world, and the crew would provide ample genetic material for a viable planetary population. Moreover, the simulation of a major engineering failure was a cleverly conceived tactic to prevent detection of the mutiny until the mutineers could move beyond possible interception by other Fleet units. Fleet Captain Anu knew that Senior Fleet Captain Druaga would transmit a malfunction report. If no further word was received, Fleet Central’s natural assumption would be that the damage had been sufficient to destroy the ship.”

“I see. But I gather from your choice of tense that the mutiny failed?”

“Incorrect, Commander.”

“Then it succeeded?” MacIntyre asked, scratching his head in puzzlement.

“Incorrect,” Dahak said again.

“Well it must have done one or the other!”

“Incorrect,” Dahak said a third time. “The mutiny, Commander, has not yet been resolved.”

MacIntyre sighed and leaned back in resignation, crossing his arms. Dahak’s last statement was preposterous. Yet his concept of words like “preposterous” was acquiring a certain punch— drunk elasticity.

“All right,” he said finally. “I’ll humor you. How can a mutiny that started fifty thousand years ago still be unresolved?”

“In essence,” Dahak said, seemingly impervious to MacIntyre’s irony, “it is a condition of deadlock. Senior Fleet Captain Druaga instructed Comp Cent to render the interior of the ship uninhabitable in order to force evacuation of the vessel by mutineers and loyalists alike, after which Dahak’s weaponry would command the situation. Only loyal officers would be permitted to reenter the vessel once the interior had been decontaminated, at which point Fleet control would be restored.

“Unknown to Senior Fleet Captain Druaga, however, Fleet Captain Anu had implanted contingency instructions in his back-up engineering computers and isolated them from Comp Cent’s net. Those instructions were intended to destroy Dahak’s internal power rooms, with the ultimate goal of depriving Comp Cent of power and so destroying it. As chief engineer, and armed with complete knowledge of how the sabotage had been achieved, it would have been comparatively simple for him to effect repairs and assume control of the ship.

“When Comp Cent implemented Senior Fleet Captain Druaga’s orders, all loyal personnel abandoned ship in lifeboats. Fleet Captain Anu, however, had secretly prepared several sublight parasites for the apparent purpose of marooning any crewmen who refused to accept his authority. In the event, his own followers made use of those transports and a small number of armed parasites when they evacuated Dahak, with the result that they carried to Earth a complete and functional, if limited, technical base. The loyalists, by contrast, had only the emergency kits of their lifeboats.

“This would not have mattered if Fleet Captain Anu’s sabotage programs had not very nearly achieved their purpose. Before Comp Cent became aware of and deactivated them, three hundred and ten of Dahak’s three hundred and twelve fusion power plants had been destroyed, dropping Dahak’s internal power net below minimal operational density. Sufficient power remained to implement a defensive fire plan as per Senior Fleet Captain Druaga’s orders, but not to simultaneously decontaminate the interior and effect emergency repairs, as well. As a result, Comp Cent was unable to immediately and fully execute its orders. It was necessary to repair the damage before Comp Cent could decontaminate, yet repairs amounted to virtual rebuilding and required more power than remained. Indeed, power levels were so low that it was impossible even to operate Dahak’s core tap. This, in turn, meant that emergency power reserves were quickly drained and that it was necessary to spend extended periods rebuilding those reserves between piecemeal repair activities.

“Because of these extreme conditions, Comp Cent was dysfunctional for erratic but extended periods, though automatic defensive programs remained operational. Scanner recordings indicate that seven mutinous parasites were destroyed during the repair period, but each defensive action drained power levels still further, which, in turn, extended Comp Cent’s dysfunctional periods and further slowed repairs by extending the intervals required to rebuild reserve power to permit reactivation of sufficient of Comp Cent to direct each new stage of work.

“Because of this, approximately eleven Terran decades elapsed before Comp Cent once more became fully functional, albeit at marginal levels, and so was able to begin decontamination. During that time, the lifeboats
