Gravity — or any centripetal facsimile thereof — did not appeal to me. I set up my own tent in zero-gee and as far to stern as possible, nuzzling the forward wall of the starboard shuttle tube. The tent inflated like an abscess on Theseus’ spine, a little climate-controlled bubble of atmosphere in the dark cavernous vacuum beneath the ship’s carapace. My own effects were minimal; it took all of thirty seconds to stick them to the wall, and another thirty to program the tent’s environment.
Afterwards I went for a hike. After five years, I needed the exercise.
Stern was closest, so I started there: at the shielding that separated payload from propulsion. A single sealed hatch blistered the aft bulkhead dead center. Behind it, a service tunnel wormed back through machinery best left untouched by human hands. The fat superconducting torus of the ramscoop ring; the antennae fan behind it, unwound now into an indestructible soap-bubble big enough to shroud a city, its face turned sunward to catch the faint quantum sparkle of the Icarus antimatter stream. More shielding behind that; then the telematter reactor, where raw hydrogen and refined information conjured fire three hundred times hotter than the sun’s. I knew the incantations, of course — antimatter cracking and deconstruction, the teleportation of quantum serial numbers — but it was still magic to me, how we’d come so far so fast. It would have been magic to anyone.
Except Sarasti, maybe.
Around me, the same magic worked at cooler temperatures and to less volatile ends: a small riot of chutes and dispensers crowded the bulkhead on all sides. A few of those openings would choke on my fist: one or two could swallow me whole. Theseus’ fabrication plant could build everything from cutlery to cockpits. Give it a big enough matter stockpile and it could have even been built another Theseus, albeit in many small pieces and over a very long time. Some wondered if it could build another crew as well, although we’d all been assured that was impossible. Not even these machines had fine enough fingers to reconstruct a few trillion synapses in the space of a human skull. Not yet, anyway.
I believed it. They would never have shipped us out fully-assembled if there’d been a cheaper alternative.
I faced forward. Putting the back of my head against that sealed hatch I could see almost to Theseus’ bow, an uninterrupted line-of-sight extending to a tiny dark bull’s-eye thirty meters ahead. It was like staring at a great textured target in shades of white and gray: concentric circles, hatches centered within bulkheads one behind another, perfectly aligned. Every one stood open, in nonchalant defiance of a previous generation’s safety codes. We could keep them closed if we wanted to, if it made us feel safer. That was all it would do, though; it wouldn’t improve our empirical odds one whit. In the event of trouble those hatches would slam shut long milliseconds before Human senses could even make sense of an alarm. They weren’t even computer-controlled. Theseus’ body parts had reflexes.
I pushed off against the stern plating — wincing at the tug and stretch of disused tendons — and coasted forward, leaving Fab behind. The shuttle-access hatches to Scylla and Charybdis briefly constricted my passage to either side. Past them the spine widened into a corrugated extensible cylinder two meters across and — at the moment — maybe fifteen long. A pair of ladders ran opposite each other along its length; raised portholes the size of manhole covers stippled the bulkhead to either side. Most of those just looked into the hold. A couple served as general-purpose airlocks, should anyone want to take a stroll beneath the carapace. One opened into my tent. Another, four meters further forward, opened into Bates’.
From a third, just short of the forward bulkhead, Jukka Sarasti climbed into view like a long white spider.
If he’d been Human I’d have known instantly what I saw there, I’d have smelled murderer all over his topology. And I wouldn’t have been able to even guess at the number of his victims, because his affect was so utterly without remorse. The killing of a hundred would leave no more stain on Sarasti’s surfaces than the swatting of an insect; guilt beaded and rolled off this creature like water on wax.
But Sarasti wasn’t human. Sarasti was a whole different animal, and coming from him all those homicidal refractions meant nothing more than predator. He had the inclination, was born to it; whether he had ever acted on it was between him and Mission Control.
