“Very well, then,” Tsh't cut in. “Galaxy Two is our goal. Tanith Sector. Tanith World. I will tell Kaa to proceed.”
In theory, clients weren't supposed to interrupt their patrons. Though Tsh't was only trying to be efficient.
At the same time Sara thoughtâ
We're heading toward Earth. Soon we'll be so near that Sol will be a visible star, just a few hundred parsecs away, practically round the corner.
That may be as close as I ever get.
Gillian Baskin answered with a nod.
“Yes, let us proceed.”
A
BOUT ONE SUBJECTIVE DAY AFTER SETTING
forth, pursuing the mysterious interlopers, Harry learned that an obstacle lay dead ahead.
Hurrying across a weird province of E Space, he dutifully performed his main task, laying instrument packages for Wer'Q'quinn alongside a fat, twisty tube that contained the entire sidereal universe. All the galaxies he knewâincluding the complex hyperdimensional junctions called transfer pointsâlay circumscribed
within the Avenue. Whenever he paused to stare at it, Harry got a unique, contorted perspective on constellations, drifting nebulae, even whole spiral arms, shimmering with starlight and glaring emissions of excited gas. It seemed strange, defying all intuitive reason, to know the domain inside the tube was unimaginably more vast than the constrained realm of metaphors surrounding it.
By now he was accustomed to living in a universe whose complications far exceeded his poor brain's ability to grasp.
While performing the job assigned to him by Wer'Q'quinn, Harry kept his station moving at maximum prudent speed, following the spoor left by previous visitors to this exotic domain.
Something about their trail made him suspicious.
Of course what I should be doing is lying low till Wer'Q'quinn's time limit expires, then collect the cameras and scoot out of here before this zone of metareality transmutes again, melting around my ship and taking me with it!
So dangerous and friable was the local zone of eerie shapes and twisted logic that even meme creaturesâthe natural life order of E Spaceâlooked sparse and skittish, as if incarnated ideas found the region just as unpleasant as he did. Harry glimpsed only a few simple notion-beasts grazing across the prairie of fuzzy, cactuslike trunks. Most of the mobile concepts seemed no more complex than the declarative statementâ
I am.
As if the universe cared.
His agile vessel made good time following the trail left by prior interlopers. Objects made of real matter left detectable signs in E Space. Tiny bits of debris constantly sloughed or evaporated off any physical object that dared to invade this realm of reified abstractions. Such vestiges might be wisps of atmosphere, vented from a life-support system, or clusters of hull metal just six or seven atoms wide.
The spoor grew steadily warmer.
I wonder why they came through here
, he thought. The oldest trace was about a year old â¦Â if his
Subjective Duration Meter could be trusted, estimating the rate at which protons decayed here, converting their mass into microscopic declarative statements. From dispersal profiles, he could tell that the small craft in frontâthe earliest to pass byâwas no larger than his mobile station.
They must have been desperate to come this way
 â¦Â
or else terribly lost.
The second spoor wasn't much younger, coming from a bigger vessel, though still less massive than a corvette. It had nosed along in evident pursuit, avidly chasing after the first.
By sampling drifting molecules, Harry verified that both vessels came from his own life order.
Galactic
spacecraft, carrying oxygen-breathing life-formsâactive, vigorous, ambitious, and potentially quite violent.
The third one had him confused for a while. It had come this way more recently, perhaps just days ago. A veritable cloud of atoms still swirled in its wake. Sampling probes waved from Harry's station, like the chem-sense antennae of some insect, revealing metal-loceramic profiles like those associated with mech life.
As an acolyte of the Institutes, Harry was always on the lookout for suspicious behavior by machine entities. Despite precautions programmed into mechs for billions of years, they were still prone to occasional spasms of uncontrolled reproduction, grabbing and utilizing any raw materials in sight, making copies of themselves at exponentially increasing rates.
Of course this was a problem endemic to all orders, since opportunistic proliferation was a universal trait of anything called “life.” Indeed, oxygen breathers had perpetrated their own ecological holocausts in the Five Galaxies, sometimes overpopulating and using up planets much faster than they could restore themselves. Hence laws of migration that regularly set aside broad galactic zones for fallow recovery. But machine reproduction could be especially rapid and voracious, often beginning in dark corners where no one was looking. Once, a wave of autonomous replicators had built up enough momentum to seize and use up every small
planetoid in Galaxy Three within the narrow span of ten million years, converting each gram into spindly automatons â¦Â which then began disassembling
planets.
The calamity continued until a coalition of other life orders intervened, bringing it to a halt.
Nor were machines Harry's sole concern. At times like this, when oxygen-breathing civilization was distracted by internal struggles, it was important to keep watch lest the rival culture of hydrogen breathers take advantage.
Still, the traces Harry picked up seemed more strange than dangerous. The lavish amount of metallic debris suggested that this particular mech could be damaged. And there were other anomalies. His sensors sniffed amino acids and other organic detritus. Perhaps small amounts of oxy-life were accompanying the machine-vessel. As cargo perhaps? Sometimes mechs used biological components, which were more resistant than prim logic circuits to damage by cosmic rays.
At the stroke of a midura, he had to halt the pursuit in order to lay another of Wer'Q'quinn's packages, aligning it carefully so the cameras peered straight into the Avenue, collecting data for NavInst technicians. Harry hoped it would prove valuable.
Of course his boss had plenty of measurements already, from probes that laced each transfer point, as well as hyperspatial levels A, B, and C. Moreover, travelers routinely reported conditions they encountered during their voyages. It seemed obscure and unconventional to send Harry all this way gathering information from such a quirky source. But who was he to judge?
I'm near the bottom of the ol' totem pole. I can just do my job as well as possible, and not try to second-guess my chief.
In pre-mission briefings, Harry had learned that strain gauges were showing increased tension along nearly every navigable route in the Five Galaxies. Ruptures and detours had grown routine as commerce began suffering noticeably. Yet, when Wer'Q'quinn made inquiries to high officials at Navigation Institute headquarters, the response consisted of little more than bland, reassuring nostrums.
These events are not unexpected.
Provisions have been made (long ago) for dealing with the phenomena.
Agents at your level should not concern themselves with causes, or long-term effects.
Perform your assigned tasks. Protect shipping. Safeguard the public. Continue reporting data. Above all, discourage panic. Hearten civil confidence.
Maintain your equipment at high levels of readiness.
Cancel all leaves.
It wasn't the sort of memorandum Harry found exactly inspiring. Even Wer'Q'quinn seemed disturbedâthough it wasn't easy to read the moods of a land-walking squid.
The situation prompted Harry to wonder again about his current mission.
Perhaps Wer'Q'quinn didn't clear my trip with his bosses. He may have sent me to get a look at things from a perspective that no one at HQ could co-opt, anticipate, or meddle with.
Harry appreciated his supervisor's confidence â¦Â while at the same time worrying about what it implied.
Could everything be falling apart?
he pondered.
Maybe the Skiano proselyte is right. If this is the end of the world, what can you do but look to the state of your own soul?
Just a midura before taking off on this mission, with some mixed feelings and trepidation, he had accepted an invitation from the Skiano to visit its small congregation of converts. Entering a small warehouse bay in one of the cheaper quarters of Kazzkark, he found a motley assortment of creatures following the strange new sect.
There had been a pair of portly synthiansâcreatures traditionally friendly to Terran customs and conceptsâalong with several little wazoon, a goggle-eyed pring, three por'n'aths, a striped ruguggl, and â¦
Harry recalled rocking back in surprise, dismayed to see a cluster of terrifying Brothers of the Night! With
muscular, streamlined arms and sharklike faces, Brothers were famed for their intense though fickle religious impulses, sampling different creeds and pursuing them fanaticallyâuntil the next one came along. Still, it shocked Harry to see them in such a gregarious setting, worshiping alongside beings who had no relationship at all with their race or clan.
The variegated faithful had gathered before a symbol that Harry found at once both quaint and unnerving â¦Â a holo portrait of
Earth
, homeworld to his neo-chimpanzee line, depicted with cruciform rays of sacred illumination emanating outward. As the hologram turned, the planet seemed to swell â¦Â then burst apart, donating its own substance to the brilliant rays, enhancing the gift of enlightenment with an act of ultimate self-sacrifice.
Then, moments later, the world recoalesced in a feat of miraculous resurrection, beginning the cycle once more.
“We are taught that the aim of life is its own perfection,”
preached the Skiano, speaking first in a flashing dialect of Galactic Two, with glitters from its lower pair of eyes, then almost simultaneously via audible Gal-Seven through a vodor held in one hand.
“This wisdom is true, beyond arty doubt. It crosses all boundaries of order or class. Once sapiency is achieved, life must be about more than mere self-gene-ego continuation. Long ago, the Progenitors taught that our highest purpose is to seek a
sense
of purpose. For existence to have meaning, we need a goal. A target at which to aim the projectile of our lives.
“But what in the universe
is
perfectible? Surely not matter, which decays, eventually reducing even the greatest artifacts and monuments to a dim glow of heat radiation. Any individual organism will age and eventually die. Some memories may be downloaded or recorded, but true improvement grinds to a halt.
“Even the cosmos we perceive with our senses appears doomed to entropy and chaos.
