Conservation of Shadows - By Yoon Ha Lee Page 0,46

memories of the wielder.

“One more has surfaced,” Kerang says. “The character in the maker’s mark resembles a sword in chains. They are already calling it Arighan’s Chain.”

“What does it do?” she says, because he will tell her anyway.

“This one kills the commander of whoever is shot,” Kerang says, “if that’s anyone at all. Admirals, ministers, monks. Schoolteachers. It’s a peculiar sort of loyalty test.”

Now she knows. “You want me to destroy the Chain.”

Once upon a universe, a duelist named Shiron took up the gun that an empress with empiricist tendencies had given her. “I don’t understand how a gun that doesn’t work could possibly be perilous,” the empress said. She nodded at a sweating man bound in monofilament so that he would dismember himself if he tried to flee. “This man will be executed anyway, his name struck from the roster of honored ancestors. See if the gun works on him.”

Shiron fired the gun . . . and woke in a city she didn’t recognize, whose inhabitants spoke a dialect she had never heard before, whose technology she mostly recognized from historical dramas. The calendar they used, at least, was familiar. It told her that she was 857 years too early. No amount of research changed the figure.

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 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
