David Weber - Empire from the Ashes

"On your way, then," he said, and the engineer stepped into the airlock.

As per Cohanna's insistence, there was no contact between Chernikov's workboat and the battle station, but Chernikov studied the looming hull yet again as Chandra floated across the kilometer-wide gap on his suit propulsors. This ancient structure was thousands of years younger than Dahak , but the warship had been hidden under eighty kilometers of solid rock for most of its vast lifespan. The battle station had not. The once bright battle steel was dulled by the film of dust which had collected on its age-sick surface and pitted by micro-meteor impacts, and its condition made Chernikov chillingly aware of its age as Dahak 's shining perfection never had.

Chandra touched down neatly beside a small personnel lock, and his implants probed at the controls.

"Hmmmmm... ." The tension in his voice was smoothed by concentration. "Dahak was right, Commander. I've got live computers here, but damned if I recognize the machine language. Whups! Wait a minute, I've got something—"

His voice broke off for an agonizing moment, then came back with a most unexpected sound: a chuckle.

"I'll be damned, sir. The thing recognized my effort to access and brought in some kind of translating software. The hatch's opening now."

He stepped through it and it closed once more.

"Pressure in the lock," he reported, his fold-space com working as well through battle steel as through vacuum. "On the low side—'bout point-six-nine atmospheres. My sensors read breathable."

"Forget it right now, Jehru."

"Never even considered it, sir. Honest. Okay, inner lock opening now." There was a brief pause. "I'm in. Inner hatch closed. The main lighting's out, but about half the emergency lights're up."

"Is the main net live, or just the lock computers?"

"Looks like the auxiliary net's up. Just a sec. Yes, sir. Power level's weak, though. Can't find the main net, yet."

"Understood. Give me a reading on the auxiliary. Then I want you to head up-ship. Keep an eye out for..."

Colin rested in his couch, eyes closed, concentrating on his neural feed as Chandra penetrated the half-dead hulk, gaining in confidence with every meter. It showed even in the technicalities of his conversation with Vlad.

Colin only hoped they could ever dare to let him come home again.

"... and that's about the size of it," Cohanna said, deactivating her personal memo computer. "We hit Chandra's suit with every decon system we had. As near as Dahak and I can tell, it was a hundred percent sterile before we let him unsuit, but we've got him in total isolation. I think he's clean, but I'm not letting him out of there until I'm certain."

"Agreed. Dahak? Anything to add?"

"I am still conversing with Omega Three 's core computers, Captain. More precisely, I am attempting to converse with them. We do not speak the same language, and their data transmission speed is appreciably higher than my own. Unfortunately, they also appear to be quite stupid." Colin hid a smile at the peeved note in Dahak's voice. Among the human qualities the vast computer had internalized was one he no doubt wished he could have avoided: impatience.

"How stupid?" he asked after a moment.

"Extremely so. In fairness, they were never intended for even rudimentary self-awareness, and their age is also a factor. Omega Three 's self-repair capability was never up to Fleet standards, and it has suffered progressive failure, largely, I suspect, through lack of spares. Approximately forty percent of Omega Three 's data net is inoperable. The main computers remain more nearly functional than the auxiliary systems, but there are failures in the core programming itself. In human terms, they are senile."

"I see. Are you getting anything at all?"

"Affirmative, sir. In fact, I am now prepared to provide a hypothetical reconstruction of events leading to Omega Three 's emplacement."

"You are?" Colin sat straighter, and others at the table did the same.

"Affirmative. Be advised, however, that much of it is speculative. There are serious gaps in the available data."

"Understood. Let's hear it."

"Acknowledged. In essence, sir, Fleet Captain (Biosciences) Cohanna was correct in her original hypothesis at Defram. The destruction of all life on the planets we have so far encountered was due to a bio-weapon."

"What kind of bio-weapon?" Cohanna demanded, leaning forward as if to will the answer out of the computer.

"Unknown at this time. It was the belief of the system governor, however, that it was of Imperial origin."

"Sweet Jesu," Jiltanith breathed. "In so much at least wert thou correct, my Hector. 'Twas no enemy wreaked their destruction; 'twas themselves."

"That is essentially correct," Dahak said. "As I have stated, the data are fragmentary, but I have recovered portions of memoranda from the governor. I hope to recover more, but those I have already perused point in that direction. She did not know how the weapon was originally released, but apparently there had been rumors of such a weapon for some time."

"The fools," Cohanna whispered. "Oh, the fools! Why would they build something like this? It violates every medical ethic the Imperium ever had!"

"I fear my data sample is too small to answer that, yet I have discovered a most interesting point. It was not the Fourth Imperium which devised this weapon but an entity called the Fourth Empire ."

For just a moment, Colin failed to grasp the significance. Dahak had used Imperial Universal, and in Universal, the differentiation was only slightly greater than in English. "Imperium" was umsuvah , with the emphasis on the last syllable; "Empire" was umsuvaht , with the emphasis upon the second.

"What?" Cohanna blinked in consternation.

"Precisely. I have not yet established the full significance of the altered terminology, yet it suggests many possibilities. In particular, the Imperial Senate appears to have been superseded in authority by an emperor— specifically, by Emperor Herdan XXIV as of Year Thirteen-One-Seven-Five."

"Herdan the Twenty-Fourth ?" Colin repeated.

"The title would seem significant," Dahak agreed, "suggesting as it does an extremely long period of personal rule. In addition, the date of his accession appears to confirm our dating of the Defram disaster."

"Agreed," Colin said. "But you don't have any more data?"

"Not of a political or societal nature, Captain. It may be that Omega Three will disgorge additional information, assuming I can locate the proper portion of its data core and that the relevant entries have not decayed beyond recovery. I would not place the probability as very high. Omega Three and its companions were constructed in great haste by local authorities, not by Battle Fleet. Beyond the programming essential for their design function, their data bases appear to be singularly uninformed."

Despite his shock, Colin grinned at the computer's sour tone.

"All right," he said after a moment. "What can you tell us about the effects of this bio-weapon and the reason the fortifications were built?"

"The data are not rich, Captain, but they do contain the essentials. The bio-weapon appears to have been designed to mount a broad-spectrum attack upon a wide range of life forms. If the rumors recorded by Governor Yirthana are correct, it was, in fact, intended to destroy any life form. In mammals, it functioned as a neuro-toxin, rendering the chemical compounds of the nervous system inert so that the organism died."

"But that wouldn't kill trees and grasses," Cohanna objected.

"That is true, Commander. Unfortunately, the designers of this weapon appear to have been extremely ingenious. Obviously we do not have a specimen of the weapon itself, but I have retrieved very limited data from Governor Yirthana's own bio-staff. It would appear that the designers had hit upon a simple observation: all known forms of life depend upon chemical reactions. Those reactions may vary from life form to life form, but their presence is a constant. This weapon was designed to invade and neutralize the critical chemical functions of any host."
