Colin fought a sense of incredulity. Nobody could build a shield with that much surface area! Yet if Dahak said they were shield generators, shield generators they were … but the scope of such a project!
“Whatever else it was, the Empire was no piker,” he muttered.
“As thou sayst,” Jiltanith agreed. “Yet methinks—”
“Status change,” Dahak said suddenly, and a bright-red ring circled a massive installation in distant orbit about Birhat itself. “Core tap activation detected.”
“Maker!” Tamman muttered, for the power source which had waked to sudden life was many times as powerful as Dahak’s own.
“New detection at nine-point-eight light-hours. I have a challenge.”
“Nature?” Colin snapped.
“Query for identification only, sir, but it carries a Fleet Central imperative. It is repeating.”
“Respond.”
“Acknowledged.” There was another brief silence, and then Dahak spoke again, sounding—for once—a bit puzzled. “Sir, the challenge has terminated.”
“What do you mean? How did they respond?”
“They did not, sir, beyond terminating the challenge.”
Colin raised an eyebrow at Jiltanith’s holo-image, and she shrugged.
“Ask me not, my Colin. Thou knowest as much as I.”
“Yeah, and neither of us knows a whole hell of a lot,” he muttered. Then he drew a deep breath. “Dahak, give me an all-hands link.”
“Acknowledged. Link open.”
“People,” Colin told his crew, “we’ve just responded to a challenge—apparently from Fleet Central itself—and no one’s shooting at us. That’s the good news. The bad news is no one’s talking to us, either. We’re moving in. We’ll keep you informed. But at least there’s something here. Hang loose.
“Close link, Dahak.”
“Link closed, sir.”
“Thank you,” Colin said, and leaned back, rubbing his hands up and down the arm rests of his couch as he stared at the crowded, enigmatic display. More light codes were still appearing as Dahak moved deeper in-system, and the active core tap’s crimson beacon pulsed at their center like a heart.
“Well, we found it,” Colin said, rising from the captain’s couch to stretch hugely, “but God knows what it is.”
“Aye.” Jiltanith once more manned her own console in Command Two, but her hologram sat up and swung its legs over the side of her couch. “I know not what chanced here, my Colin, but glad am I Geb is not here to see it.”
“Amen,” Colin said. He’d once wondered why Geb was the only Imperial with a single-syllable name. Now, thanks to Jiltanith and Dahak’s files, he knew. It was the custom of his planet, for Geb had been one of those very rare beings in Battle Fleet: a native-born son of Birhat. It was a proud distinction, but one Geb no longer boasted of; his part in the mutiny had been something like George Washington’s grandson proclaiming himself king of the United States.
“But whate’er hath chanced, these newest facts do seem stranger still than aught else we have encountered.” Jiltanith coiled a lock of hair about her index finger and stared at Command Two’s visual display, her eyes perplexed.
With good reason, Colin thought. In the last thirty-two hours, they’d threaded deeper into the Bia System’s incredible clutter of deep-space and orbital installations until, at last, they’d reached Birhat itself. There should have been plenty of room, but the Bia System had not escaped unscathed. Twice they passed within less than ten thousand kilometers of drifting derelicts, and that was much closer than any astrogator cared to come.
Yet despite that evidence of ruin, Colin had felt hopeful as Birhat herself came into sight, for the ancient capital world of the Imperium was alive, a white-swirled sapphire whose land masses were rich and green.
But with the wrong kind of green.
Colin sat back down, scratching his head. Birhat lay just over a light-minute further from Bia than Terra did from Sol, and its axial tilt was about five degrees greater, making for more extreme seasons, but it had been a nice enough place. It still was, but there’d been a few changes.
According to the records, Birhat’s trees should be mostly evergreens, but while there were trees, they appeared exclusively deciduous, and there were other things: leafy, fern-like things and strange, kilometer-long creepers with cypress-knee rhizomes and upstanding plumes of foliage. Nothing like that was supposed to grow on Birhat, and the local fauna was even worse.
Like Earth, Birhat had belonged to the mammals, and there were mammals down there, if not the right ones. Unfortunately, there were other things, too, especially in the equatorial belt. One was nearly a dead ringer for an under-sized Stegosaurus, and another one (a big, nasty looking son-of-a-bitch) seemed to combine the more objectionable aspects of Tyrannosaurus and a four-horned Triceratops. Then there were the birds. None of them seemed quite right, and he knew the big Pterodactyl-like raptors shouldn’t be here.
It was, he thought, the most God-awful, scrambled excuse for a bio-system he’d ever heard of, and none of it—not a single plant, animal, saurian, or bird they’d yet examined—belonged here.
If it puzzled him, it was driving Cohanna batty. The senior biosciences officer was buried in her office with Dahak, trying to make sense of her instrument readings and snarling at any soul incautious enough to disturb her.
At least the sadly-eroded mountains and seas were where they were supposed to be, loosely speaking, and there were still some clusters of buildings. They were weather-battered ruins (not surprisingly given the worn-away look of the mountain ranges) liberally coated in greenery, but they were there. Not that it helped; most were as badly wrecked as Keerah’s had been, and there was nothing—absolutely nothing—where Fleet Central was supposed to be.
Yet some of the Bia System’s puzzles offered Colin hope. One of them floated a few thousand kilometers from Dahak, serenely orbiting the improbability which had once been the Imperium’s capital, and he turned his head to study it anew, tugging at the end of his nose to help himself think.
The enigmatic structure was even bigger than Dahak, which was a sobering thought, for a quarter of Dahak’s colossal tonnage was committed to propulsion. This thing—whatever it was—clearly wasn’t intended to move, which made all of its mass available for other things. Like the weapon systems Dahak’s scanners had picked up. Lots of weapon systems. Missile launchers, energy weapons, and launch bays for fighters and sublight parasites Nergal’s size or bigger. Yet for all its gargantuan firepower, much of its tonnage was obviously committed to something else … but what?
Worse, it was also the source of the core tap Dahak had detected. Even now, that energy sink roared away within it, sucking in all that tremendous power. Presumably it meant to do something with it, but as yet it had shown no signs of exactly what that was. It hadn’t even spoken to Dahak, despite his polite queries for information. It just sat there, being there.
“Captain?”
“Yes, Dahak?”
“I believe I have determined the function of that installation.”
“Well?”
“I believe, sir, that it is Fleet Central.”
“I thought Fleet Central was on the planet!”
“So it was, fifty-one thousand years ago. I have, however, been carrying out systematic scans, and I have located the installation’s core computer. It is, indeed, a combination of energy-state and solid-state engineering. It is also approximately three-hundred-fifty-point-two kilometers in diameter.”
