Lightspeed: Year One

Later, Shiron deduced that the man she had executed traced his ancestry back 857 years, to a particular individual. Most likely that ancestor had performed some extraordinary deed to join the aristocracy, and had, by the reckoning of Shiron’s people, founded his own line.

Unfortunately, Shiron didn’t figure this out before she accidentally deleted the human species.

“Yes,” Kerang says. “I have been charged with preventing further assassinations. Arighan’s Chain is not a threat I can afford to ignore.”

“Why didn’t you come earlier, then?” Shiron says. “After all, the Chain might have lain dormant, but the others—”

“I’ve seen the Mercy and the Needle,” he says, by which he means that he’s copied data from those who have. “They’re beautiful.” He isn’t referring to beauty in the way of shadows fitting together into a woman’s profile, or beauty in the way of sun-colored liquor at the right temperature in a faceted glass. He means the beauty of logical strata, of the crescendo of axiom-axiom-corollary-proof, of quod erat demonstrandum.

“Any gun or shard of glass could do the same as the Mercy,” Shiron says, understanding him. “And drugs and dreamscalpels will do the Needle’s work, given time and expertise. But surely you could say the same of the Chain.”

She stands again and takes the painting of the mountain down and rolls it tightly. “I was born on that mountain,” she says. “Something like it is still there, on a birthworld very like the one I knew. But I don’t think anyone paints in this style. Perhaps some art historian would recognize its distant cousin. I am no artist, but I painted it myself, because no one else remembers the things I remember. And now you would have it start again.”

“How many bullets have you used?” Kerang asks.

It is not that the Flower requires special bullets—it adapts even to emptiness—it is that the number matters.

Shiron laughs, low, almost husky. She knows better than to trust Kerang, but she needs him to trust her. She pulls out the Flower and rests it in both palms so he can look at it.

Three petals fallen, a fourth about to follow. That’s not the number, but he doesn’t realize it. “You’ve guarded it so long,” he says, inspecting the maker’s mark without touching the gun.

“I will guard it until I am nothing but ice,” Shiron says. “You may think that the Chain is a threat, but if I remove it, there’s no guarantee that you will still exist—”

“It’s not the Chain I want destroyed,” Kerang says gently. “It’s Arighan. Do you think I would have come to you for anything less?”

Shiron says into the awkward quiet, after a while, “So you tracked down descendants of Arighan’s line.” His silence is assent. “There must be many.”

Arighan’s Flower destroys the target’s entire ancestral line, altering the past but leaving its wielder untouched. In the empire Shiron once served, the histories spoke of Arighan as an honored guest. Shiron discovered long ago that Arighan was no guest, but a prisoner forced to forge weapons for her captors. How Arighan was able to create weapons of such novel destructiveness, no one knows. The Flower was Arighan’s clever revenge against a people whose state religion involved ancestor worship.

If descendants of Arighan’s line exist here, then Arighan herself can be undone, and all her guns unmade. Shiron will no longer have to be an exile in this timeline, although it is true that she cannot return to the one that birthed her, either.

Shiron snaps the painting taut. The mountain disintegrates, but she lost it lifetimes ago. Silent lightning crackles through the air, unknots Zheu Kerang from his human-shaped shell, tessellates dead-end patterns across the equations that make him who he is. The painting had other uses, as do the other things in this room—she believes in versatility—but this is good enough.

Kerang’s body slumps on the couch. Shiron leaves it there.

For the first time in a long time, she is leaving Blackwheel Station. What she does not carry she can buy on the way. And Blackwheel is loyal because they know, and they know not to offend her; Blackwheel will keep her suite clean and undisturbed, and deliver water, near-freezing in an elegant glass, night after night, waiting.

Kerang was a pawn by his own admission. If he knew what he knew, and lived long enough to convey it to her, then others must know what he knew, or be able to find it out.

Kerang did not understand her at all. Shiron unmazes herself from the station to seek passage to one of the hubworlds, where she can begin her search. If Shiron had wanted to seek revenge on Arighan, she could have taken it years ago.

But she will not be like Arighan. She will not destroy an entire timeline of people, no matter how alien they are to her.
